A Compost Happening

I feed and water my compost “pets,” and they do the same for my plants.

Homemade Butterfinger Ice Cream

Here is an excellent recipe for homemade Butterfinger ice cream.

A vegetable garden is more than what you see on the surface — dirt, plants and (hopefully!) some mulch. Under the surface, a complex web of dirt, roots, microbes and fungi transforms plain old dirt into a superior growing medium — soil. But that intricate web will exist only if you boost your plain old dirt with nutritious amendments, such as homemade compost. And in addition to being a garden soil amendment, compost can be worked into the soil around trees, bushes and flowers to also give them a nutritional boost.

Composting is a natural process, similar to the way nature breaks down leaves and other dead material on the forest floor. A combination of green and brown vegetable matter kept barely moist and turned regularly will “rot” into a dark, aromatic material filled with the beneficial bacteria, microbes and fungi that your plants need to grow like champs.

Getting Started

Where will you work your compost? You can easily make a 3-to-4-foot-wide “cage” from chicken wire, welded wire or plastic gardening fencing to contain your compost materials. Place the compost cage in a corner of your garden, where the nutrients carried by rainwater will feed vegetables planted nearby. If there’s no room in the garden install it as close as possible because you’ll also want to add weeds and culled vegetables to the compost heap. Leave a space of equal size adjacent to the container (more on this below).

If you don’t want to build your own cage, there are numerous sizes and shapes of commercial compost tumblers available. While tumblers are compact and convenient to use, a well managed-compost pile can handle a lot more material — and is almost free.

What to Add — Or Not

The best compost heaps contain a good variety of green and brown ingredients:

  • whole or chopped leaves and stalks (if chopped, they will break down quicker)
  • vegetable and fruit trimmings
  • herbicide-free grass clippings
  • weeds
  • straw or hay
  • shredded paper or cardboard
  • manure from grazing animals

If you have too much wet, green material (grass clippings and fruit or veggie trimmings), the pile may get smelly. If you have too much dry, brown material (chopped leaves, straw or shredded paper), the heap will take much longer to decompose. So, a fairly equal ratio of greens and browns will produce the most efficient pile.

There are a few ingredients you should never add to your composting pile:

  • meat
  • oily or greasy food and paper
  • manure from meat-eating animals, such as dogs and cats
  • herbicide-treated grass or other clippings

Keep it Going

Now that you have a pile of mixed vegetable matter, what do you do with it? You will want to keep it damp, similar to a wrung-out sponge. To speed up the decomposing process (this is where the space beside the container comes in) turn the material every week or two. The easiest way to do this is to lift the cage off and set it next to the pile. Then fork the pile back into the cage, thus inverting and mixing the material. If the material seems dry, spray it with your garden hose while you’re turning the pile. It is not necessary to turn the pile, but it will accelerate the process. Over time, unless you are adding a lot of new material, your pile will decrease in size as it decomposes.

Within a few months of adding to the mix and regularly turning it, you will have rich, nutritious compost to add to your garden soil.

I VISIT my local STARBUCKS about once a week. They save me their used coffee grounds which goes into my compost.

It is one of the best "browns" you could get. Just a little addition of lime neutralizes the acidity.

I add all but the worst weeds to my pile. I will not add vines like ivy or morning glory as they will root nearly anywhere, but most weeds once pulled up die rather than rooting in your compost, and if you get them before they go to seed you don't have much to worry about. I try to pull weeds when they are still too small to have produced seeds but even if I don't, I am not worried. If weed seeds aren't growing in my compost pile, why would they suddenly sprout when I spread the compost? They've had access to heat and moisture and all the nutrients they can get. If they're going to grow, they'll grow before the compost is finished. I've known of potatoes and other garden crops growing out of an un-turned compost pile, but I've rarely seen weeds make it!

I got six free pallets from a local store; stained them (not necessary); nailed them into a frame and voila...bins for compost piles with three sides and open front. Plus it re-purposes the pallets. Works like a charm.

If you are interested in a hot compost pile, and you don't have access to manure from grazing animals, do a google search on joe jenkins and read his free book on humanure. Another way to save mother earth, and cut back on pollution of fresh clean drinking water.

Weeds, seeds, etc all no problem IF and only IF your compost pile is large enough that it is generating sufficient HEAT to kill off the weeds, seeds, roots etc etc. I make quite a large compost pile and weeds and everything goes into it and then I'll leave them in there and providing there is sufficient heat generated by the compost decomposing, enough air and enough moisture the heat inside the pile can be too hot to touch which is plenty hot enough to "cook" the seeds. Not sure what the temp needs to be, but if you leave the seeds inside that cooking compost long enough they are NOT going to grow when you put it out on your garden.

I've never started a compost pile but my research so I can do so during this winter has all said "no weeds". Can the author of the article explain their reason for addding weeds, please.

How much percentage wise manure or green matter should be added so the heat will be high enough to kill weed seeds?

I'm surprised that this article mentions adding weeds to the compost. I have read in other articles to not add weeds as their seeds can sprout in your garden.
