The goal of succession planting is simple — to enjoy a continuous and uninterrupted supply of fresh vegetables. This type of planting is particularly important in small backyard gardens, where space is at a premium. Many of my favorite crops for succession planting are those that thrive in the cool and cold weather of spring and fall. They enjoy an extended growing season, unlike the warm season crops, which have a very specific window of cultivation between the frost dates.

Succession planting starts with a little planning. Make a list of what you want to grow, and then write in the expected planting dates and the number of days to harvest. This will tell you how long it will take from the time you plant until you can expect to start harvesting the crop. Because some crops, like leaf lettuce, can produce over an extended period, it’s also helpful to know the general length of the expected harvest. Once the crop is finished, it’s time to replant.

In addition to creating an endless harvest, practicing succession planting can help you outwit certain insect pests by avoiding their prime season. For example, if squash vine borers are a problem in your garden, planting a second crop of zucchini in early summer, after the adults have finished laying their eggs, will help ensure that you get to enjoy the fruits of your labor. To put succession planting to work for you, keep the following tenets in mind.

Keep on Seeding

One of the easiest ways to practice succession planting is simply to keep on seeding. This technique works best with quick-growing vegetables, like lettuce, arugula, radishes, and bush beans, which can be planted every few weeks. Continual sowing will produce a staggered harvest — that is, your whole crop isn’t ready at the same time. After all, who needs to have a whole packet of radish seed mature at once? For a family of four, it makes more sense to sow about 20 radish seeds every 2 weeks. Once radishes reach maturity, they start to lose their quality rather quickly. By planting in succession, you’ll be able to harvest perfectly mature radishes for months.

In order to keep on seeding, you’ll need to leave space in your garden bed for subsequent plantings. In our garden, a 4-by-4-foot bed is often divided into six mini rows, each measuring about 8 inches wide and planted right up next to each other. No wasted space! I can sow a mini row of leaf lettuce or mesclun mix every 2 weeks for a continuous crop from early spring to late fall. By the time your second and third mini rows are ready to harvest, the first is exhausted and ready for the compost heap. Work an inch of compost into the original row and then replant with more leaf lettuce, or another crop of your choice.

Some crops that are ideal for this type of succession planting are most salad greens, radishes, bush beans, beets, kohlrabi, and carrots.

Pick and Sow

I also like to practice the pick-and-sow type of succession planting. This allows me to grow a continuous series of vegetables in the same space over the course of the gardening year by following one crop with another. Once the first crop is finished, I remove it and plant another in its place. For example, I often follow spring radishes with Black Seeded Simpson lettuce, followed by arugula, followed by tomatoes, followed by a crop of fall radishes. The garden space is never empty, and by varying the types of vegetables that are grown in each successive planting, I help prevent the depletion of certain nutrients. Any crop can be grown with this technique, as long as you’re planting at a time appropriate to the vegetable (cool, warm, or cold season) and leaving enough time for the crop to mature.

Another easy way to use the pick-and-sow method is to let the season dictate what you’ll plant. For example, start with a cool-season crop, like peas or broccoli, that can be planted very early in the spring (super-early crops can be grown under mini hoop tunnels). Once this initial crop has been harvested, the weather will have warmed up and a warm-season crop — corn, tomatoes, or bush beans — can be planted in the same space. After a late-summer harvest, pull the warm-season crop and replace it with another cool- or cold-season vegetable — kale, arugula, winter lettuce, spinach, radishes, or mâche, for example.

Choose Staggered Cultivars

My family loves broccoli, so I like to have an ample supply on hand from early summer to late autumn. Keeping a handful of broccoli transplants on hand for succession planting every few weeks is a pain, though; I’m just not that organized! I rely on the third succession planting technique, choosing staggered cultivars, which enables me to make just two plantings — one in spring for a summer harvest and one in midsummer for a fall harvest. The key is to select varieties that mature at different times, so each harvest, summer and fall, is extended for as long as possible. You can buy separate varieties or you can buy a mixed packet of seed (often called All-Season Blend or something similar). By planting early, mid-, and late-maturing types of broccoli at once, our summer harvest stretches over a period of about 2 months instead of 3 weeks. This mixture of maturity dates prevents all 40 of our broccoli plants from being ready at the same time, which might be fine for a market garden but not for a backyard family vegetable patch. No matter how much we like it, one family can eat only so much broccoli.

This technique will also work on many other crops, including cabbage, cauliflower, kohlrabi, beets, turnips, potatoes, tomatoes, and peas.

Five Gardening Tips Successful Succession Planting

Plan in advance. Although I can’t claim to be a super-organized gardener, I’m always sure to order enough seed with my annual orders for a full year of succession planting. A bonus is that, if stored properly, most seed will easily keep for several years, so even if you don’t use it all that first season, you can save the rest for the future.

Start more seedlings. By mid-May, my warm-season veggie seedlings have been planted in the garden, and the space under my grow light is empty. But it’s not time to unplug for the season. Instead, I start planning for succession crops and fall/winter harvests. I start by planting more cucumber seeds, which are relatively quick growing and will supply a second crop of crisp cukes for a late-summer harvest, just when the first crop starts to lose steam. Also, I’ll seed more celery for a second yield in late summer and fall. The first planting tends to get pithy and hollow if left to mature. Then, in mid-June, I’ll plant a new crop of broccoli and kale that will be transplanted to the garden in late July for a cool- and cold-season harvest. With a little protection, the kale will keep producing throughout the winter.

Feed the soil. To keep production high, I always add a 1-inch layer of compost to the garden between successive crops. If your soil isn’t overly fertile, add a granular organic fertilizer at this time; just be sure to follow the directions on the package.

Turn over plantings quickly. To get the most out of your space, remove any spent crops immediately after harvest or as soon as their production declines. Don’t wait for the last few peas to mature — just haul out the plants, toss them on the compost pile, and replant right away with another family favorite.

Don’t forget rotation. Although it’s easy to get caught up in the whirlwind of succession planting, it’s important to keep in mind what's planted where. A notebook will come in handy! Try to group families (for example, legumes — beans, peas, soybeans). If certain diseases or insects are an annual issue, it is essential to keep rotating your crops. A three-year rotation is considered adequate for most problems, although the longer the rotation, the better.

Top Five Vegetables for Succession Planting

1. Leaf lettuce. Because we eat so many salads and because it’s so quick and easy to grow, I rely on leaf lettuce to fill in any unexpected empty spaces in the garden. A quick sprinkling of seed results in a generous harvest in just a few weeks. What could be easier? Plus, with such an array of leaf colors, shapes, and textures, lettuces are as pretty as they are productive.

2. Arugula. Arugula is another workhorse in the garden. It tolerates the unstable weather of early spring and late autumn, and grows so quickly that its nickname is “rocket.”

3. Bush beans. Bush beans are an ideal veggie for succession planting, as many varieties are ready to harvest in just 50 days. We start sowing seed directly in the garden in mid-May and continue to sow seed every 2 to 3 weeks until late July.

4. Radishes. Perhaps the perfect succession crop, radishes are ridiculously fast growing; they’re often ready for harvest in just 21 days. Unless you have a serious hankering for radishes, just sow a small amount of seed every week or two for a continuous supply of fresh roots. You can also succession-plant an assortment of varieties for an extended harvest. We like ‘Cherry Belle’ (21 days), ‘French Breakfast’ (28 days), and ‘White Icicle’ (35 days).

5. Carrots. One of my garden goals is to have fresh carrots ready for harvest 365 days a year! Although that takes both planning and luck, we are able to enjoy carrots most of the year. In spring, summer, and fall, baby carrots are ready to pick in just under two months! You can also get a jump on the spring crop by sowing a band of seed in the cold frame in late winter.
