The compost adds much needed nutrients, the expanded shale breaks up the clay, and the greensand acidifies our very alkaline soils.

How to Make Compost



Composting is a technique used to accelerate the natural decay process. The technique converts organic wastes to a mulch which is used to fertilize and condition soil. Leaf waste decomposes naturally in about two years. Composting can take as long as a year or as little as 14 days.


Most yard wastes can be composted, including leaves, grass clippings, plant stalks, vines, weeds, twigs and branches. Compostable food wastes include fruit and vegetable scraps, coffee grounds, eggshells and nutshells. Other compostable materials are hair clippings, feathers, straw, livestock manure, bonemeal and bloodmeal.

The soil must also be amended below the original soil level to a depth of 4-6 inches for optimum plant performance.

To prepare the bed, dig out the existing clay soil to a depth…
