If you’ve been reading your gardening catalogs, you’ve probably seen advertisements for activators that accelerate the composting process.
To get the whole process started, you need to have a population present of the microorganisms that actually do the work.
Under most conditions, the best ingredients to use as activators are garden soil and compost. Soil contains the organisms that will break down the organic material into more soil, so it makes a great bio-activator.
Unless your soil is seriously deficient in organic matter, it should be enough to start the composting process. If you’re in doubt, add some fully decomposed compost as a starter.
