Homegrown Paleo – Compost Happens

In my last Homegrown Paleo blog we explored sheet mulching an in-place passive composting system that instantly transforms a space into a garden. This post explores good old-fashioned compost. I love it when people ask me how to establish a landscape or garden. It gives me the opportunity to help at the ground level and advise them on proper soil preparation. My advice? You guess it – add compost.

Technically speaking, composting is a process that results in a product called humus. This happens through the microbial decomposition of organic material into a nutrient-rich and fertile soil amendment. Not only does compost provide innumerable benefits to your plants and landscape, it’s also free to make and reduces the amount of green waste sent to the local landfill.

Many people have the misconception that composting is messy, smelly and attracts vermin. This is not true. When done correctly, composting is easy and results in vigorous plants and bountiful garden crops. It is probably the most valuable thing you can do for your yard.

The basic compost recipe is equal parts of green material and brown material, plus a little soil, water and air. Green material includes fresh organic waste, such as grass clippings, deadheaded flowers and kitchen scraps. Brown material is dried or dead organic waste, such as fallen leaves, dried grass, pruned wood, shredded newspaper or cardboard. Never add meat scraps, pet waste, weeds with seeds, or diseased materials to your compost pile. All materials you add should be less than 2 inches in size so that it will break down quickly.

Select a location for your compost pile that is tucked away somewhere in your yard, or simply build it where you eventually want to build your garden. Make sure the area you select gets about six hours of sunlight each day. You can heap all of the material together in a loose pile, construct a simple bin, or purchase a commercially made compost bin. This MSU Extension Publication will help you get started.

Once you have found a place for your composting venture, it’s time to pile up your green and brown materials. It should be at least 3 feet to 4 feet square. About every foot, add an inch or two of soil, which will supply microbes to decompose the organic matter. Add water as you go. The microbes need water and air in order to get to work, so keep the compost pile wet, but not soggy. It should be about as damp as a wrung-out sponge. If it is too wet, the process will switch from aerobic to anaerobic decomposition, and the pile WILL smell.

Air is the final ingredient and is added to the recipe by turning your pile. Let the pile sit for about two days and then check the temperature. You can poke your hand into the middle of the pile, or use a thermometer. Once the internal temperature is about 160 F, it is time to turn it. This will aerate the pile, but decrease the temperature. Continue to monitor the heat, and turn the pile again when it reaches 160 F. If you continue turning the pile every time it heats back up to 160 F, you should have usable humus in about two or three weeks. It is important to not add any new materials if you are actively turning your pile.

Alternatively, you can just leave the pile sit, and not turn it. The composting will still take place, but much more passively. It will take more time – sometime up to a year – but will not require as much effort by you. Either way, you will enjoy seeing your plants thrive as your compost does its magic in your soil.
