How to Make Soil Compost Tea


Water and compost combined make a tea that can be used to water and fertilize flowers and vegetables. Compost tea is available pre-made at many nurseries and garden centers or can be made at home, using the traditional method of soaking well-matured compost. Compost tea has long been used by organic gardeners, and according to the University of Connecticut Cooperative Extension is gaining in popularity with mainstream gardeners as they look for natural ways to improve their gardens and yields.

Step 1

Fill a burlap sack, or other loosely woven fabric bag, with well-matured compost, using a shovel.

Step 2

Tie the top of the bag tightly with string.

Step 3

Place the bag into a 5-gallon or larger bucket or barrel.

Step 4

Fill the bucket with water. Press the bag of compost beneath the surface of the water. Allow the bag to seep in the water for at least an hour. The longer the bag remains in the water, the more beneficial the tea will become. Allow the bag to soak for several weeks, if desired.

Step 5

Remove the bag from the water. Use the "compost tea" to water garden plants. Use the wet compost in the burlap bag as mulch for other plants.
