Safety Warnings

Avoid excessive moisture to prevent leaching of nutrients into the surrounding soil.

stainless steel hand trowel — for mixing and turning materials

garden fork — for aerating the compost heap

organic waste — green and brown organic materials(as needed)

moist soil — nutrient-rich garden soil(small amount for layering)

Select a site for your compost heap, preferably in a location that allows for natural drainage.

Tip: Avoid areas where runoff could cause leaching of nutrients.

Prepare the base by adding a layer of moist soil to provide a foundation for the heap.

Tip: Moist soil is superior to coal ashes for initiating the composting process.

Begin adding organic waste materials to the heap, layering greens and browns.

Tip: Waste nothing to maximize the amount of organic matter processed.

Ensure the pile remains moist to support the activity of minute organisms and bacteria.

Tip: Maintain consistent moisture to prevent the process from stalling.

Avoid allowing the pile to become overly saturated to prevent anaerobic fermentation.

Tip: Proper aeration prevents foul odors and nutrient loss.

Allow the materials to decompose slowly over time without the need for frequent turning.

Tip: Cold composting relies on natural decomposition rates over a longer period.

Harvest the finished compost once it has broken down into a dark, crumbly texture.

Tip: Apply the finished compost to the ground before planting to enrich the soil.

Use a variety of organic wastes to ensure a balanced nutrient profile in the final compost.
Moist soil is a better starter for compost heaps than coal ashes.
