If you’re interested in making a compost pile, you’ve come to the right place. We’ve put together the following information to help guide you during your compost pile creation.
Before we get going, let’s make sure you’re in the right place. The information below is specifically for those of you that want to compost outdoors on a small-scale (e.g. backyard or urban composting). If you’re interested in learning more about large-scale composting, please visit the following page – Build a Compost Pile (large-scale composting).
Now that we know you’re in the right place, let’s get started.
There are several different methods you can use when making a compost pile; however, for the purposes of this guide we’ve chosen a method we learned from Elliot Coleman, one of our organic gardening gurus. The following guidelines have been adapted from Coleman’s text – The New Organic Grower. If you haven’t read this book, please please PLEASE do yourself the honor and order it now.
Are you an avid composter? If so, please skip this section. If not, there are a few basic composting topics we want to cover before we begin building our piles.
The key to making high quality compost begins with an understanding of these three critical areas:
Sometimes this can be the most difficult part of the entire compost-building process, especially when you live in an urban area. This becomes even more challenging if you’re living in a newly-developed urban area; there are so few sources of organic matter (e.g. large trees) in new subdivisions.
Whatever your living situation, here are some suggestions to help you find compost ingredients locally:
Ideally, when making a compost pile, you’re able to collect ALL of your compost ingredients before you start building the pile. However, that’s typically not the case. Instead, what usually happens is that you build your compost pile gradually over a period of several months.
This is an important step in making compost. Once you have your ingredients, you want to form them into a pile using alternating layers. For example, in the diagram below, we have repeating layers of 3″ of straw, 2″ of fresh grass clippings, and 1″ of topsoil mixed with rock dust.
Depending on your specific composting materials, you may have to experiment with different thicknesses of each layer.
Why do we recommend adding rock dust to your compost?
In this example, rock dust is used to describe a natural mineral powder that can be added to compost to encourage biological activity and add nutrients to the final compost product. Soil microbes love this stuff and help to shuttle it into your plants. For more information on rock dusts and how they can take your growing to the next level of productivity, please sign up for our email updates and compost newsletter.
There are many different compost bins and techniques that you can use to contain your ingredients; however, in this example we’re following Elliot Coleman’s advice and he recommends building a compost bin using a straw-bale enclosure.
Why straw bales?
Using straw bales to build a compost bin is similar to using concrete blocks. Be sure to interlock the bales from layer to layer. To create additional air flow, leave spaces between adjoining bales (see diagram below).
Below are a few diagrams to help you when you’re making a compost pile using straw bales to build your bin.
We need to answer one final question about making a compost pile – how often should you turn it?
In Coleman’s book, he says that once a pile is built in the above manner, there is no need to turn it. As long as you monitor the pile’s moisture and keep it covered (use a tarp, an old rug, a piece of carpet, or a 3-4 inch layer of topsoil), your compost should be ready within 18 months.
If you don’t want to wait that long, we suggest turning your pile at least once a month. If built and maintained properly, your compost should be ready within 6-8 months.
