Vermicompost is the product of the decomposition process using various species of worms, usually red wigglers, white worms, and other earthworms, to create a mixture of decomposing vegetable or food waste, bedding materials.
 
Vermicompost, or castings, is worm manure. Worm castings are considered by many in horticulture to be one of the best soil amendments available. The nutrient content of castings is depends on the material fed to the worms–and worms commonly feed on highly nutritious materials, such as food waste and manures.
 
Vermicompost has a profound effect on plants. It boosts the nutrients available to plants, helping seeds to germinate more quickly, grow faster, develop better root systems and produce higher yields. That means more flowers or fresh fruits and vegetables.
 
The worm compost can be used as a general soil conditioner or as a constituent of homemade growing media. It is generally rich in nitrogen and potassium. The liquid drained from wormeries can be used as a liquid fertilizer on garden plants after diluting with water at a rate of 1 part liquid to 10 parts water.
