How to Make Your Own High-Quality Compost

By on July 27, 2012

Tricia shows you how to make high quality compost like this, with the fast and hot method.

Cook up your own FAST, high-quality compost and either use it immediately in your garden, or brew it for a great compost tea.

Compost is one of the cornerstones of organic gardening and we have loads of information for you about compost and compost tea.

*  Want to make fast compost to enrich the soil in your garden? Our video shows you how to do that in easy steps.

*  Do you want to brew large amounts of aerated compost tea? Watch our video about making aerated compost tea in commercial size quantities, with our Growing Solutions Compost Tea Brewer System.

*  If you’re a home gardener, check out our video about brewing 5 gallons of aerated compost tea in our own PVFS Compost Tea Brewer. An article explaining aerated compost tea is linked to the video.

As in any recipe, the finished product is only as good as the ingredients. The better your compost, the better your compost tea. By “better” we mean there are more microorganisms in the tea, bringing more life to your soil.

What is high quality compost?

High quality compost comes from a carefully tended compost pile with the right mixture of brown and green matter, water, and oxygen. When all is working optimally in a pile it will reach high temperatures of 120-150°F. The high heat will kill most pathogens and weed seeds, but the beneficial mycorrizhae will survive. There is a natural “cooling off” period and then the compost is “finished compost” or “humus” and can be put to use.

To make the best compost you should create a fast, hot compost pile (in a bin or on the ground) and add all the composting ingredients at once. If you manage your compost pile well, you can have finished compost in 2-8 weeks.

*  Fill your compost bin, or build the pile by layering equal amounts of brown and green ingredients. The pile should not be bigger than a 3-foot cube, since you will need to be able to turn it often. If you are composting outside a bin, in a windy area, you should go up to a 4-foot cube size, to retain the heat better. With this fast process you will need to watch the balance of brown and green ingredients as the composting goes along, and be prepared to supplement with more brown or green if the pile develops problems.

*  Speed up decomposition by using small pieces of ingredients (shredded leaves, not whole leaves, for instance). Don’t use branches in a fast compost pile, because they take longer to break down.

Spray water on each layer. Kick up the speed in the pile by adding compost inoculants to the water you spray on the pile. Keep the pile as moist as a wrung-out sponge at all times. Be careful when you touch the pile because it will be HOT using this composting technique.

Turn the pile every 3 days with a digging fork or compost aerator tool.

Monitor the temperature of a fast compost pile. Your friends who are new to gardening will squawk when they hear you own a compost thermometer, but you’ll have the last laugh when you produce superb compost in a few weeks. A speedy pile may go up to 120°F in the first 2 days, and up to 130°F in 3 to 4 days. When the temperature drops to 110°F the compost may be close to finished, if your pile has been performing at the fastest rate—or it may need a boost of additional turning and water to heat up again.

Compost is “finished” when it is dark, crumbly, and sweet-smelling. You should not be able to identify the original pieces of the ingredients. Let it sit for a few days, then spread it an inch thick in your garden, or use it to make your compost tea!
