Now that it’s July, the heat and humidity have reached our part of the Midwest, and it’s as if a drowsy spell has been suddenly cast over the farm.  We find that the days are somehow busy, yet lazy at the same time.

Each day begins early, trying our best to take advantage of any cool remaining from the night before and before the sun is fully up. Work continues until it is simply too hot to pull another weed, till another row, or shift another load of spent hay from the goat shed. This is when the drowsy of summer seems to settle in; the comforts of life on the farm: the rumble of distant thunder, the sweet scent of just-mowed grass, or the hum of a combine harvesting winter wheat.

Somehow the temptation to “just rest my eyes” is too great, and I find myself inside Maizy, our little 1963 camper, “resting” and listening to the sounds of summer. While there are always chores that need doing, I decide to work on them tomorrow. I promised a young friend I’d share some gardening lessons I’ve learned along the way, and jotting them down in the quiet of a cozy retro camper seems like a good idea.  

This young lady is right out of high school and knows exactly what she wants: to live a homesteader’s life.  She’s reaching for her dream by selling home-baked bread, setting up a coop with 6 happy hens, and planting a vegetable garden. She and I have been talking gardens lately, because it seems that July is a turning point…the days are hot, the rain is less, and the weeds and pests seem to come out with strong determination. And so, while sharing my tips & tricks with her, I thought you just might find some new solutions for your own gardens as well.

These “recipes” have been handed down through the years and do a great job for me. However; there is no guarantee and you may find you need to make adjustments depending on the “critters” or conditions in your own garden. All in all, my thoughts are this: these simple remedies are usually effective and won’t harm the environment. To me, that makes them worth a try!

First; set up a Garden Farm-acy…you probably already have these items in your pantry, paired with a few fresh ingredients, you’ll use them for the “recipes” below:

Epsom salts, canola oil, baking soda, ground cinnamon, apple cider vinegar, hot sauce, cayenne pepper, liquid soap (not laundry detergent)

Tomato Booster – combine 2 Tablespoons Epsom salts in 1 gallon of water; stir to dissolve. Once tomato plants have begun to bloom, pour this solution on the soil surrounding the plant…it’ll encourage stronger, healthier blooms and tomatoes.

Tomato Blight Fight – 1 Tablespoon canola oil, 1 teaspoon baking soda, 1 gallon water; combine and shake to blend. Spray on plants early in the season to help fight fungal blight.

Critter Ridder – pour ½ cup apple cider vinegar, 1 teaspoon hot sauce, and 1/4 teaspoon liquid soap in a spray bottle; gently shake to blend and spray on the undersides of leaves. This peppery spray is great for discouraging critters who want to nibble on garden plants.

Cinnamon Spray – ¼ teaspoon ground cinnamon stirred into 2 cups warm water; shake to dissolve. Pour into a spray bottle and spray on leaves to fight powdery mildew.

Mite Fighter – ¼ cup buttermilk, 2 cups whole wheat flour, 2-1/2 gallons water, combine and spray on plants.   

Pepper Hot Shot – 2 Tablespoons cayenne pepper, 5 drops liquid dish soap, 1 gallon water; combine all and spray underside of leaves to fight beetles.

Garlic Spray Concentrate -  4 cloves minced garlic combined with 1 Tablespoon oil; set aside overnight. Strain mixture and add to 2 cups water along with 1 teaspoon dish soap; shake to blend.  To use: Dilute first:  Fill a spray bottle with 2 cups water and 2 Tablespoons Garlic Concentrate; shake. Spray undersides of leaves to discourage beetles and mites.

I hope these natural remedies help in keeping your garden healthy so you can enjoy the fruits of your summertime labor!

Grow Successful Sweet Corn

Caring for Your Sweet Corn Crop

Sweet corn needs hoeing and weeding at least twice, once two weeks after sowing, and once at four weeks. Even better are four rounds: at 7, 14, 21 days (when the plants are 6-12” (15-30cm) tall) and finally one around 35 days when they are 18-20” (45-50cm) high. We use a walk-behind tiller, and follow up with hoeing and thinning. A wheel hoe can be a great tool for this job if you don’t have or want a rototiller.

Never allow soil in corn plantings to dry out. At tight spacing this becomes very important. You might need more than 1” (2.5cm) per week for maximum productivity, although corn is more drought tolerant than some crops. The most important times for watering are silking (when the silks first become visible outside the husks) and while the ears are filling out.

Flame-weeding can be used after planting before the corn emerges, or after the crop is 2” (5cm) tall, using a carefully directed flame. Consult ATTRA Flame Weeding for Vegetable Crops

People used to recommend removing the suckers that came from the base of the plant, thinking it led to higher yields. This idea has been tested, and in fact it can damage plants and possibly even reduce yields.

Undersowing Cover Crops in Sweet Corn

Another practice that has been shown to lower yields rather than raise them is planting into strips tilled in a white clover living mulch.  Jeanine Davis addresses this in NCSU’s Organic Sweet Corn Production. The clover can out-compete the corn, become invasive and hard to get rid of. Soil temperatures will be lower (a disadvantage in spring) and slugs and rodents may increase.

A more successful practice is sowing a cover crop into the corn 28-35 days after emergence. We undersow with soybeans (oats and soybeans for our last planting). Although soybeans don’t supply the highest amount of nitrogen compared to other legumes, soybeans are cheap, quick, somewhat shade tolerant and can withstand the foot traffic during harvesting. Other growers sow forage brassicas. Research has shown that this does not depress corn yields. The brassicas can be harvested for forage after the sweet corn harvest is finished. Undersowing with white clover is also possible, if you can leave it to grow after the corn is finished.

Harvest Sweet Corn All Summer

In order to have a continuous supply of sweet corn all summer, a bit of planning and record-keeping is called for so that each year’s plan can be fine-tuned. The easy and approximate method of getting a good supply is to sow more corn when the previous sowing has 3-4 leaves, or is 1-2” (2.5-5cm) tall. That will be about every two weeks.

For fine-tuning for the most even supply, nothing beats real information about what happened, written at the time it happened. We have a Planting Schedule on a clipboard in the shed, and we write down actual sowing dates (next to the planned sowing date), and harvest start and finish dates. See Growing sweet corn for the whole summer to read about the Succession Planting method to calculate best planting dates and intervals for a continuous supply. We make six plantings: 4/26, 5/19, 6/6, 6/24, 7/7 and 7/16, to provide fresh eating every two weeks. The planting intervals are 23, 18, 18, 13, and 9 days.

By planting three varieties each time, we get new corn coming in three times during each two weeks. Sow varieties with differing days to maturity. We sow Bodacious (77 days), Kandy Korn (89 days) and Silver Queen (96 days) on the same day, and get over two weeks of harvests.

Early Maturing Sweet Corn Varieties

Remember, if you decide to grow several kinds, not to mix Sh2 kinds with anything else, or everything will taste starchy. For more on this, see my previous article Growing sweet corn for the whole summer.

Early Maturing Sh2 Varieties: The Supersweet corn varieties are where most of the attention goes these days, and bicolor is preferred. In order of maturity (speediness in ripening): Catalyst XR (bicolor, 66days); Sweetness synergistic (bicolor, 68d); Kickoff XR (bicolor, 69d); Temptress synergistic (bicolor, 70d); Xtra-Tender 2171 (bicolor, 71 d); Nicole (white, 72d); Xtra-tender 20173 (bicolor, 73d); Signature XR (bicolor, 73d); Anthem XR (bicolor, 74d); Natural Sweet Organic (bicolor, 74d); Xtra-tender 3473 (white, 75d); SS2742 (Bicolor, 75d)

Early Maturing SU Varieties: Among yellow SU cultivars, Earlivee is the earliest to mature, at 58 days, and Seneca Horizon matures in 65 days. Sugar Pearl at 73d is the earliest white cultivar to mature. Quickie, at 64 days, Double Standard (OP, 73d) and Butter and Sugar at 73 d, are the earliest bicolor cultivars to mature.

Early Maturing SE Varieties: Among yellow SE varieties, Precocious and Spring Treat mature earliest, at 66 and 67 days, respectively. Bodacious (yellow, 75d) is well worth the wait! Of white varieties, Spring Snow, at 65 days, is the earliest to mature. There are no bicolor SE varieties.

Early maturing SE+ varieties: Sugar Buns (yellow, 70 days); Trinity (bicolor, 68d)

Pests and Diseases of Sweet Corn

Crows and other birds can be troublesome, removing the seed before it even grows. We leave the row-marking ropes in place after sowing. Bird-scaring flash-tape may be even more effective. Rowcover would also work.

Some say interplanting corn with big vining squashes deters raccoons and other critters, but I think it deters people too!

There are several caterpillar pests. An integrated organic approach to keeping pest numbers below economically damaging levels includes crop rotations, tillage, choosing resistant or tolerant varieties, encouraging beneficial insects, and ensuring adequate fertility and water. The next step is to scout for pests regularly, and take action as required.

Corn Ear Worm (CEW) is the most common pest. There may be six generations a year in the South. These caterpillars can bite – it’s just a nip, but can be a shock! A first line of defense is to choose varieties with tighter husks, which are harder for the worms to get into (Bodacious, Tuxedo, Silver Queen). Natural predators can be encouraged by planting alyssum or other small, open-flowered plants. You could buy Trichogramma wasps.

Caterpillars can also be dealt with putting a few drops of vegetable oil in the tip of each ear. Mixing with Bt gives better results, when applied 2-3 days past the full-brush stage of silking. . The Zea-later was a tool developed for applying vegetable oil in the tip of each ear, mixed with Bt, 2-3 days past the full-brush stage of silking. Unfortunately the treatment caused pollination problems at the tip of the ears, and so it has fallen out of use. If pest numbers are not too high, you can simply cut or snap the ends off the ears.

European Corn Borer (ECB) drills through the whorl of leaves of the young plants, leaving a pattern of large holes as the plant develops. Bt and Spinosad will kill these, as will Trichogramma wasps. To reduce damage in future years, be sure to mow and disk old corn stalks into the soil at the first opportunity. Organically farmed soils have less of a problem with ECB.

Fall Army Worms (FAW) are also killed by Bt and Spinosad. These three pests (CEW, ECB, FAW) can be monitored in a single program, starting when the corn plants are at the whorl stage. At that point, scout for FAW, and treat if more than 15% of your plants are infested. At the pre-tassel and tassel stage scout for ECB and FAW. If infestation exceeds 15%, make a foliar spray with Bt or Spinosad. Check again in a week and repeat if needed. Then at the early silk stage, look for CEW and if needed, inject oil in the tips. If you also see ECB moths, apply Bt or Spinosad.

Cutworm can be a problem following sod, or if there are adjacent grassy areas. Bait them with bran, cornmeal and hardwood sawdust mixed with molasses and water – these baits swell inside the pests and kill them. For more effectiveness, add Bt to the mix.

Corn Rootworms are best controlled by rigorous rotations. Spotted cucumber beetles are the adults of corn rootworms.

For a more complete description of corn insect pests, see the 2004 Organic Insect Management in Sweet Corn by Ruth Hazzard & Pam Westgate. It includes good photos of the beasties. Cornell has a good Resource Guide for Organic Pest and Disease Management. Search under Crop Management Practices for Sweet Corn.  Be aware of the updated info on the pollination issues with applying oil in the ear tips, since these publications came out.

Corn Smut fungus (Ustilago maydis), known in Mexico as Huitlacoche, is edible at the stage when the galls are firm and tender. The flavor is sweetish. Silver Queen is the variety “best” at producing this fungus, should you wish to grow it. We carefully harvest the infected ears (or pieces of stem) into a special Smut Bucket, trying not to scatter the spores. Because none of us like this delicacy, we take it to the compost pile.

Sweet Corn Harvest

Harvest corn before daybreak for best flavor, because the sugars manufactured in the plant the day before become concentrated during the night. Harvest may start 18-24 days after half the ear silks show, if the weather has been reasonably warm. Judging corn’s ripeness is a skill, based on information from many of the senses.

The first sign we look for is brown dead silks. If the ear has passed that test, we investigate further. All ears should look and feel plump and rounded to the tip. Each variety is a little different, so close attention is needed. Some varieties exhibit “flagging” of the ear, meaning it leans away from the stalk as it matures and gets heavier. New crew can test for ripeness by opening the side of the husk with thumb nails, and puncturing a kernel: the kernels should look filled-out and rectangular, not round and pearly; the juice should be milky, not watery or doughy. The advantage of opening the side of the husks is that it is possible to close the gap if the ear is not ripe, without risk of collecting dew or rainfall. If the ear is ripe, we bend it downwards, give it a quarter-turn twist, and then pull up away from the plant.

Harvest every day or every other day. Leaving a three-day gap risks poor quality starchy ears and a lower total yield. After harvest, refrigerate the corn quickly, and keep it cool until it reaches the boiling water.

This Tech Startup Could Reward Small Farmers for Sustainable Practices

Photo by U.S. Department of Agriculture “There’s an app for that”.

It’s not only a trademarked slogan of Apple, it's becoming a fact of life. Well, what if I were to tell you that there is a new app in development that will help reward farmers for adopting sustainable practices. An app that will create a marketplace for farmers to sell their produce directly to buyers, and allows farmers to cooperatively purchase inventory to lower their operating costs.

Seems like a big ask right? Well, that is exactly what the folks over at the Carbon Drawn Initiative are building with Genihub, A tool designed to reward farmers for adopting sustainable practices, and much, much more. But before we dive into what exactly GeniHub is, I want to give you a bit of a background.

The Soil from Which this Tech Springs

Tokya Dammond, a co-founder of the Carbon Drawn Initiative, is a family friend. Over the years, I have done a lot of odd jobs for him as I grew up. From cutting his grass to attempting to fix his old, out-of-date BMW. During the years of working with Tokya, I learned about his company, SymBio.

Symbio is an international company that Tokya used to develop organic supply chains. A company he has operated for three decades, SymBio has always encouraged farmers and companies to adopt more sustainable practices, oftentimes working with farmers directly to teach them how to be more sustainable and creating an avenue for them to sell their produce.

This 30-year experience has played a crucial role in the development of the GeniHub tool, created by the Carbon Drawn Initiative. So what exactly is GeniHub?

Take a Look at GeniHub

Tokya Dammond, Co-founder of The Carbon Drawn Initiative, says to “think of it as the combination of Facebook, Amazon, and PayPal of Regenerative Food. Farmers will love how Geni automates all their payments plus their bookkeeping and accounting for you — it doesn’t matter which bank or accounting program you use. Geni is designed to truly be your "Geni in the bottle" (or in this case, in their smartphones). All the while helping farmers steward their land while growing nutritious foods.”

Genihub performs a lot of roles including to track produce from the seed stock to the farmer, and from the farmer to the production line. It allows farmers to co-op and buy equipment, seed, fertilizer, and more, and creates a new marketplace for farmers to sell directly to buyers. Finally, it allows corporations to reward farmers for adopting sustainable practices.

GeniHub will Track Produce from Source to Table

GeniHub will track a farmer's purchases like the seed and fertilizer they purchase. And follow the produce as it is grown all the way to the manufacturing plant they are sent to.

How is this helpful?  Well, not only will GeniHub help manage your accounting. It will act to verify that your produce is grown the way you say it is. In much the same way that farmers pay hefty fees to get their produce certified as organic or non-GMO. GeniHub will improve the integrity of produce, and increase consumer confidence in the products they purchase, at no added cost to farmers.

For example, if an oat farmer in Wisconsin does not use synthetic fertilizers, and practices crop rotation. GeniHub will be able to verify this with their purchase history, and other auditing methods. This will allow consumers to be more informed about the products they are purchasing. Which can create a deeper level of trust in a product that does not currently exist.

The App Will Allow Farmers to Co-op for Purchases

“Being able to work with other farms would help us learn and utilize different technologies,” says Nate Krause, Operations Manager at Swans Trail Farms. “It is one thing to get hard data on our growing practices, but being able to interpret the information and apply them to our growing program is key.”

To put it simply, things are better when we work together. However, that is not always as simple as it seems. But GeniHub creates a collaborative space for farmers as part of what they call “Regen Street”. Essentially the Wall Street for regenerative farmers.

The technology will allow farmers to take advantage of bulk discounts by allowing them to collectively purchase seed, fertilizer, and pesticides. Additionally, farmers can co-op to purchase equipment that they need to implement a new sustainable practice, but simply cannot afford on their own.

And through the tracing of which practices work and don’t work, GeniHub will be able to provide feedback on what practices or produce work best in each region.

Creates a B2B and B2C Marketplace

In many ways, GeniHub serves as both a Facebook of sorts combined with an Amazon marketplace. Verifying products exist and that they are the quality they are said to be.

Farmers small and large will collectively gain access to a global market of businesses and consumers. Here they can list their produce and set their own price. And even allow them to negotiate with buyers through the GeniHub network.

For example, let's say two farmers offer a similar oat product. Both have been verified as being non-GMO crops grown without pesticides. One farmer wants $2 a pound for his products and another is happy with $1 a pound. Meanwhile, the buyer is willing to pay $1.50 a pound.

In this scenario, Geni will notify each of them and automate the sale by serving as the “middleman”, much like how eBay automates the sale of a T-shirt. Additionally, the buyer will get details he wouldn’t otherwise receive about the produce such as; the region where the produce was grown if any pesticides were used, the variety of seed that was used, and any other practices the farmer may have implemented.

Allows Corporations to Reward Farmers Sustainable Practices

“Carbon Drawn plans to donate Geni to farmers around the world so that you will be able to login and have all of your marketplace transactions automated,” says Dammond. “Better yet, farmers can connect with other farmers to enter markets together. Even connecting with NGOs for financial assistance. Geni even allows you to connect directly to consumers and larger buyers. Geni will be able to authenticate the quality of inputs and products all along the way.”

In my opinion, this is one of the coolest features of the GeniHub marketplace. Here’s the deal: Corporations know that the last century of mono-cropping agriculture is simply unsustainable. And the last thing a corporation that turns a profit selling food wants is a collapse in the supply chain due to a new disease, drought, or other natural disaster.

As a result, corporations are constantly creating incentives for farmers to develop more sustainable practices. From purchasing carbon credits to giving farmers grants for practicing crop rotation. Corporations are continually looking to invest in more sustainable agriculture to stabilize their supply chains. As a result, farmers large and small can receive benefits, or higher profit margins by adopting better practices. And GeniHub will allow farms of all sizes to access these grants.

How Farmers Can Be Involved

GeniHub will aim to revolutionize the way that produce is grown, bought, and sold around the world. Furthermore, it creates a tool that small and mid-sized farmers with sustainability in mind can use as leverage to compete with the mega-farms using “conventional” farming practices.

Best of all, the tech is free for small farmers who qualify. The application is expected to be released and functional by the end of 2021. Only time will tell how impactful this app will be on the market, but it couldn’t have arrived at a better time.

Illustrated Guide to Growing Radishes

With proper planting and care, your small radish patch can award you with plenty of delicious harvest.
Photo by Michael Feldmann

Radishes are incredibly easy to grow, as they tolerate most soil types and are very quick to be ready for harvest (usually within three to four weeks). They’re delicious when eaten raw, offering a fiery burst of flavor to salads.

There’s a wide variety of radish cultivars to choose from, ranging from near-spherical red-and-white roots to long, thin white radishes, also known as mooli. And however, growing radishes is not hard at all. In fact, with proper planting and care, nearly anyone can become a successful radish gardener.

Choosing Your Favorite Variety

 

Radishes are so easy to care for and grow so quickly that you won't even notice when the harvest is ready.

Most commercial radishes are red, but there are white, red-and-white, and even black ones. There are two main types: ordinary ones, small and quick maturing, and winter ones, larger and more pungent. Both the flesh and skin of ordinary radishes are edible, but the skin of winter radishes should be removed to expose the white inner tissue.

Fine ordinary radish varieties are:

  • Burpee White. ‘Burpee White’ radishes, best eaten at 1″ across. It is quick and easy to grow in cool weather. They are ready to be harvested in around 25 days after planting.
  • Cherry Belle. ‘Cherry Belle’ is an extra-early variety with exceptionally short tops and bright red skin color. They are ready to be harvested in about 21 to 27 days after planting
  • French Breakfast. ‘French Breakfast’ is a large, scarlet radish, oblong in shape with white tips. The flesh is crisp, juicy, mild, and sweet. French Breakfast radishes are ready to be harvested in around 20 days after planting.

 

‘Cherry Belle’ is an excellent radish variety with exceptionally short tops and bright red skin color.

  • Sparkler. ‘Sparkler’ is ready in 25 days, bearing white roots that change to pink closer to the leafy stems. Novelty radishes, including the following, are becoming more popular.
  • White Icicle. White Icicle radishes have a snowy white color and are ready to be harvested in about 32 days. This heirloom radish can grow to be 5 to 6 inches in length and about 1 inch in diameter.

Good winter radish varieties are:

‘Round Black Spanish’ radishes have a white interior and black skin. They are ready to be harvested in around 55 days after sowing seeds.
Illustration by Mary Peterson

  • Round Black Spanish. ‘Round Black Spanish’ radishes have a snow-white interior and jet-black skin. A very old heirloom variety. They are ready to be harvested in about 55 days after planting.
  • White Chinese. Also called Celestial, white, 6 to 8 inches long, 2 to 3 inches across. A 12-foot row yields about 6 pounds over a week. They are ready to be harvested in around 60 days after planting.

Growing Radishes in the Garden

Radishes provide beauty in the garden and abundant flavor in your kitchen. Radishes are very easy to grow and, once planted, require little care besides watering and harvesting. So, if you're just getting started with an edible garden, radishes are great to start. Here are some easy tips on planting and caring for these almost carefree, beautiful, flavorful plants.

Radishes tolerate partial shade and grow best in well-worked, well-drained soil with a pH of 6.0 to 7.0. They grow fast; fertilizer applied after planting will not reach the roots, so prepare the soil before sowing: dig about 2 inches of compost or 4 inches of cow manure into a strip 12 to 18 inches wide and 8 inches deep, then add 1 pound of 10-10-10 fertilizer to every 10 feet of row.

In most of the United States and Canada, where frost is expected in winter, sow seeds of ordinary varieties in early spring when the soil can be worked and continue to plant every 10 days until a month before maximum daytime temperatures are expected to average over 80 degrees Fahrentheit. In late summer, when maximum daytime temperatures average below 80°, start successive plantings of ordinary radishes again and continue until night temperatures drop to about 40 degrees. Sow winter radishes once, about two months before minimum night temperatures average below 20 degrees; they can be harvested in fall for storing over winter.

In regions where winter temperatures rarely fall below 30 degrees, start successive plantings of both types in fall; make the final planting of ordinary radishes a month before maximum daytime temperatures average above 80 degrees, and make the final planting of winter radishes a month earlier.

Sow seeds ½-inch deep. Space ordinary varieties 12 inches apart in rows 4 to 6 inches apart. When seedlings are 1 to 2 inches tall, thin them to stand 1 inch apart. When sowing winter varieties, group three or four seeds in a spot; set each group 4 to 6 inches apart in rows 12 inches apart. When seedlings are 1 to 2 inches tall, cut off all but the strongest in each group. Give your radishes enough water to keep the roots growing quickly.

Gathering the Harvest

 

Nothing can compare to a fresh juicy harvest of homegrown radishes.

The time from planting to harvest is 20 to 30 days for spring radishes, and 50 to 60 days for winter radishes. Pull up the whole plant when the radishes are the right size. Test- pull a few or push the soil aside gently to judge the size, and remember that the biggest radishes aren't necessarily the best. If you wait too long to harvest, the centers of spring radishes become pithy.

Storing and Preserving Radishes

There are several ways of storing radishes. In the home, they can be stored for up to two weeks in zipper plastic bags in the fridge. Line the inside of the bags with moistened paper towels to keep them damp. Remove the leaves and roots but don’t wash the radishes for optimal storage.

Alternatively, radishes can be stored in the basement or cellar. This is also the longest storage method and you can expect radishes to store up to three months this way. The basement or cellar should be unheated and dark with between 34 and 42 degrees, and high humidity. The radishes should be put in cardboard or wooden boxes with moist sand or dirt. Spread the unwashed and untrimmed radishes between layers of sand or dirt, making sure the roots don’t touch. Check them once every several weeks for rot.

Radishes can also be successfully stored by pickling. This way is very easy, effective, and delicious. Wash your radishes well and remove the leaves and stems. Then slice the radishes thinly and place them in a sterilized jar. Heat vinegar, spices, sugar, and salt in a saucepan until boiling, then pour over the radishes. Seal the jar and allow it to cool. Allow the radishes to pickle for at least 2 to 3 days. This way, radishes can be stored in the refrigerator for up to 4 months.

Propagating Radishes by Saving Seeds

To save seeds from your radishes, allow several plants to bloom together, and wait until the seed pods dry and turn brown before harvesting the seeds. The seeds can be stored in a cool, dry place for up to five years.

Understand Promiscuous Pollination in Landrace Gardening

Promiscuous pollination is essential to the long-term survival of landrace crops. Some species are very promiscuous. Other species are mostly self-pollinating, crossing occasionally.

Promiscuous pollination rearranges the genetics of the plants. Shifting genetics allows life to adapt to changes in the ecosystem or in farming practices.

Pollination is Highly Localized

A flower is most likely to be pollinated by the nearest compatible flower. The closer we inter-plant different varieties, the more likely they are to cross. I typically sow the barely crossing varieties jumbled together to get the most crossing possible.

The mathematics of pollination are quadratic, meaning that doubling the distance between two flowers cuts the chances of cross-pollination to a quarter. Increasing the distance tenfold lowers the chances of cross-pollination a hundredfold.


Pollen flow between flowers. Diagram by Joseph Lofthouse

Pollen flow is highly localized
Diagram by Joseph Lofthouse

The graph showing pollen flow between flowers applies at any scale. It applies to the separate flowers in the umbel of a carrot as it does between umbels on the same plant. It applies to separate plants in the same patch, and to separate patches in the same field.

An awareness of the highly localized nature of pollination allows us to design plantings to either minimize pollination for maintaining isolation distances, or to maximize it to encourage crossing.

Purity and Isolation Distances

People express fear about saving seeds. What if they flub isolation distances? What if a variety gets polluted? How about inbreeding depression? What if the seed is a hybrid? What about poisons and deformed monster plants? My response is that those things are of little consequence.

The essential knowledge regarding seed saving is that plants produce seeds. They can be harvested and replanted. For plant breeding, add that offspring resemble their parents and grandparents. Sometimes a trait skips a generation.

Growing Landrace Populations

Growing landrace populations greatly simplifies seed saving. It reduces worry about plant purity and isolation distances. Worrying about purity is one of the biggest impediments to seed saving. Maintaining purity leads to inbreeding depression. I don’t worry much about isolation distances or keeping cultivars pure. Plants are stronger when cultivars cross-pollinate each other. If a Hubbard squash and a banana squash cross-pollinate, the offspring are still squash. They grow like squash, they look like squash, they cook like squash.

When two great varieties cross, the offspring inherit greatness. People started domesticating plants up to 40,000 years ago. The vast majority of undesirable traits have been eliminated from domesticated crops. I don’t observe crossed plants turning into poisonous mutants. When two highly domesticated varieties cross, the offspring are likewise highly domesticated. The offspring’s traits blend those of the parent varieties.

Troubleshooting When Plant Breeding Goes Wrong

Sometimes I make crosses to wild, less-domesticated parents. I hope to incorporate more diversity. Occasionally in those crosses, I find a poisonous fruit, or other undesirable traits. Melon, squash, cucumber, bean, and lettuce poisons are well behaved. They taste horrid. Terrible tastes are a good indication that a plant produces poisons. Nightshades might taste good, but the poisons make me want to barf.

I planted a “pocket melon”, which is a tiny cantaloupe with a perfume smell. I taste every fruit before saving seeds. The pocket melons tasted nasty! Poison in melons tastes horrid. I discarded the whole year’s seed crop. I couldn’t risk introducing poison into the cantaloupes.

When I introduced genetics from wild watermelons, the “exploding melon” trait appeared. If jostled while sun-warmed, the fruits popped open. Gradual selection eliminated the trait in a few years.

I consider tepary beans to be semi-domesticated. My original strains had a trait which I call “hard seed.” About 10% of the seeds wouldn’t absorb water when soaked. They would take weeks or months to germinate. I eliminated that trait by pre-soaking the seeds, and only planting those that absorbed water immediately. The wild watermelon brought the same trait with them, which self-eliminated. Watermelon is a full-season crop at my place. Plants that take a long time to germinate don’t reproduce before frost.

These days, if I choose to grow wild ancestors of domesticated crops, I grow them in a separate field for a few years. This ensures that they don’t introduce unfortunate traits. It’s easier to keep them isolated in the beginning, rather than eliminating a trait later on.

I keep hot peppers separate from sweet peppers. I don't care what a sweet pepper looks like. It can be any shape, any color, or any size as long as it is not hot. The most important sweet pepper trait in my garden is: “must produce fruit.”

Considerations for Inbreeding Crops

For the mostly inbreeding crops like common beans and grains, I consider them isolated at 10 feet (3 meters) apart. With the mostly outcrossing crops, I consider them isolated at 100 feet (30 meters) apart. I observe around 1% to 5% crossing at that distance.

Crops flowering at different times don’t cross-pollinate. An early maturing and a late maturing corn may grow next to each other, without worry of crossing. That’s how I grow flour corn and sweet corn in the same field.

Likewise, inbreeding depression is only a problem when growing a cultivar in strict isolation. It doesn't much matter how many plants are in the population if new genes arrive regularly. The inflow of new genes is counteracting the gene loss due to inbreeding.

I wonder if the “minimum number of parents” recommendations are a ruse by the mega-seed companies to discourage people from saving seeds. The standards necessary for growing a seed crop for the entire world are much different from what is required for growing local food for the local neighborhood. I’m not going to suggest magic numbers of how many plants to save seeds from. Save seeds from as many as is easy for you and your community. Be generous during selection. If a variety loses vigor, allow it to cross with something else.

I don’t care if there are a few percent off-types in what I grow. I’m harvesting by hand. I’m holding each vegetable in my hand before cooking. If I don’t like it, I compost it or feed it to animals.

Potato-Hilling Method for Northern Gardeners

We Get Lots of These 

We get lots of these

In conjunction with our recently published book, The Self-Sufficient Backyard (in Mother Earth News Store), we’ve been making short videos of how we do things around the homestead. One of the things generating interest is how we grow potatoes.

Our Method for Growing Potatoes

I know everybody has their methods for growing potatoes from covering them in hay, planting them in barrels, buckets, grow bags and the list goes on. For over 40 years, we’ve planted potatoes only one way. Why change when we have been so successful. Success for us is measured in the consistent size and quantity of potatoes a hill produces year in and year out.

Although we have not weighed our potato harvests, it’s safe to say we lug bucket after bucket down to the root cellar and inventory close to 400 pounds. We always have several buckets of small potatoes set aside for seed for the following year. Seed size is roughly the size of a golf ball, perhaps a tad larger.

Potatoes Ready For the Root Cellar

We will plant potatoes only one way: in a traditional row that is hilled up multiple times. We’ll start by defining our row with a couple of stakes and a string. The stakes are banged into the ends of the row and string tied between to use as a guide making it easier to hoe a straight furrow.

Planting Seed Potato

A furrow roughly 3 inches deep is made using a hoe and the seed is set in the furrow roughly 10 to 12 inches apart. We’ll let the sun warm the seed and soil for a few hours and then we’ll cover the furrow back up.

Weeks later after the potato has sprouted above the soil, we’ll come by and hoe soil on top completely covering the new plant. We don’t worry about killing the plant. It will emerge again. Once it has, we’re more aggressive about hilling up soil from both sides of the plant row and burying the plant again. The tuber will bust through the soil once more. With our hoe, we’ll take soil from each side of the row and bury it a third and final time.

We now have a nice straight row of potatoes that have been hilled up. The base of our row should be at least 20 inches across and the hill should be roughly 9 inches tall. It’s very important we have a good mound of soil. We will be growing many, large potatoes come fall and if some potatoes outgrow our hill, they’ll be susceptible to sun burn and greening.

I think covering the emerging plants make them mad and more determined to grow. We like to have mad, determined potato plants. Not to worry though our plants don’t stay mad at us for long and they reward us with strong healthy, plants and good eating tubers.

Now we monitor daily. We are looking for insect damage and any indications of fungal problems. Depending on the insects, it might be as simple as plucking a few beetles off or a shot of insecticidal soap or BT. Fungal might be as simple as removing and burning a few leaves or a shot of a fungicide like copper or sulfur. Sulfur would be our first choice.

Good News From Our Orchard

While we’re chatting here, I thought we might update you on our orchard we’ve talked about in previous posts. In our last post, we explained the pitfalls we’ve dealt with over the years establishing our orchards. We expressed hope that the trees planted last spring would flower this year and give us some fruit.

One of Twelve Flowering Apple Trees

It is thrilling to see twelve trees in bloom laden with lots of flowers this spring. How much fruit sets will be the million dollar question. The trees are still young and many flower clusters are on the branch tips so we want to limit production to a degree. Once we actually see small apples forming, we will probably limit each tree to a dozen apples this year.

We’ll remove the least desirable apples and leave only a small percent of the best looking apples so the trees continue to put energy into growth and root systems. Keep in mind, many of these trees were just planted last spring so we don’t want to stress them with their first fruiting. We are expecting substantial, vigorous growth and it’s important to us we don’t rush the fruit production. It is a balance between our age, ( we aren’t spring chickens) our desire for a root cellar overflowing with apples and what’s best for long term interest of the trees. What good would it do to have every branch laden with so much fruit that ultimately it breaks off from too much weight and damages the tree? So we will be patient and smart about this.

We are currently shooting video of our homestead and hope to have a virtual tour movie for people to view since it’s nice to talk about all these things but better still, to actually see them from a camera’s perspective. In the meantime, in our next chat, we’ll give you our experiences with root cellars of all kinds.

Intensive Gardening Basics for a Huge Vegetable Harvest

Do you know the best way to maximize your vegetable harvest? Gardening intensively will give you twice or thrice the amount (and types) of vegetables than you can achieve in traditional gardening. Using the same amount of land, you can learn how to plant in succession and replace everything you harvest with a new crop.

There are many methods for gardening intensively and information on two of the most popular ways can be found in Intensive Gardening. Since we take a lazy approach to gardening we came up with our own method that cuts down on the amount of work and money that many named methods require. 

Let’s take a look at how to:

  • use your gardening space wisely
  • replenish your soil
  • plan for the following growing year.

Wise Use of Spaces

Harvesting more from the same gardening space saves you both time and money. Your tasks can be planned for more efficient movement, and you’ll save both time and money because it takes less input to keep up productivity. In our main garden of 2000 square feet we grow 75% of the huge amount of vegetables our small family eats in a year.

Having a place to grow our own seedlings is a big part of our year-round abundance. We start seedlings off inside during the depths of winter to plant out as soon as the temperatures allow. During the summer we grow seedlings of fall crops so that they are ready to transplant as soon as summer crops are harvested. Our approach to lazy, yet productive, gardening includes both succession planting and inter-cropping. 

The Garden in Spring

In March we begin planting cold season crops that mature quickly. Spring radishes are ready to eat in 4 weeks, leaf lettuce can be harvested after 50 days, and small cabbages planted as seedlings are picked 6 weeks after planting. As those beds are harvested we replant them with summer crops. Vegetables with a shorter and earlier harvest season, will be followed with fall crops. For tomatoes, peppers, okra, melons, and other vegetables with a long harvest window, we’ll utilize inter-cropping or wait and plant quick growing fall/winter veggies after the summer harvest is completed.

When harvesting just a plant or two from a bed, quickly pop in fast growing seeds of another vegetable in those spots.  When harvesting an entire crop, top the soil with compost then immediately plant a second crop.  Alternate heavy feeder crops (think cabbage and corn) with light feeders such as beans or sweet potatoes.  Go vertical whenever possible on teepees and trellises so that you can plant other crops in front of, or in between, them.

Here’s what we’ve planned for a few of our beds in 2021:

  • Purple bush beans, followed by drumhead cabbage for winter harvest
  • Winter sown spinach, followed by sweet corn, and ending with rutabagas
  • Spring beets, then sweet corn, ending with winter radishes sown under the corn
  • Winter sown sugar snaps on a fence, with beets in front; zucchini rampicante on the fence with lemon squash in front; a final planting of kale to carry through into winter
  • Spring carrots, tall climbing cucumbers on the fence, and a planting of mustard late summer
  • Successions of spring lettuce, followed by caged tomatoes, and winter radishes planted wherever a tomato plant stops producing
  • Spring radishes, then lots of sweet potatoes, ending with tatsoi and Swiss chard
  • Beets, then small melons (partially on the fence), then turnips into the winter
  • Early cabbage, succeeded by bush beans, finishing off with fall beets

 using the fences

We use the fences surrounding our garden as trellises, having made the garden beds right up to the fence lines. Pole beans grow on bamboo pole teepees creating shade for summer lettuce to grow under them. In addition to the usual suspects, small melons, summer squash, and climbing cucumbers trellis well. Take the sun into consideration when planting vertically so that you know where you will be creating shade.  By planning summer shade you can carry spring crops over into the hotter months.

Feed Your Soil

Compost is an important part of the process so take a look at Create Your Own Compost for some ways of making your own without a lot of effort. The key to intensive gardening, no matter the method you use, is to regularly replenish the soil with compost. When you do that you can keep a large part of the garden planted for most of the year and harvest continually for more months than you ever thought possible. Here in Zone 6b we have something actively growing in the garden almost year ‘round and typically harvest during 10 months of the year.

A thin layer of soy bean meal on empty garden beds, topped with a layer of fluffed straw, at the end of the season will nourish your garden for the first crops of spring. You can replenish your soil with nutrients and minerals by using fish fertilizer, seaweed tea, or beneficial microbes. If your soil tends to be acidic, you should test your soil to determine its pH balance. Adding dolomitic lime at the end of the growing season will “sweeten” your soil over the winter.

Looking Ahead and Planning

During the winter months we select our seeds, deciding which crops to grow the next year and planning the garden on graph paper. The goal is to have every bed growing at least two crops during a year, while some grow as many as 3-4 crops. It’s also important to identify quick growing crops for each season that can be spot-planted as we harvest individual plants of other vegetables.

Developing a Seed Plan will help you through all the details of getting your garden plan on paper during the winter. It’s always fun to begin your gardening year in the comfort of your chair in front of the fireplace.
