How to Use Worm Compost Tea


By soaking worm compost in water, organic gardeners can create a compost tea that delivers liquid nutrients to the plant's roots for fertilizing or for preventing disease. While aerated compost tea can be difficult for beginners to master, the non-aerated worm compost tea is easy for backyard gardeners to make and use.

Worm Compost Tea

Step 1

Dump 2 to 3 cups of compost into the bottom of a 5-gallon bucket and sift through to make sure there are no worms left inside.

Step 2

Fill the bucket up, an inch or so from the top, with water from the garden hose.

Step 3

Allow the tea to "steep" for up to 7 days, stirring it once a day in order to extract all of the nutrients from the compost and allow microbes and bacteria to grow in the tea.

Step 4

Pour the tea into the soil of potted plants or use it to water your vegetable garden or flower garden up to twice a month.

Step 5

Spray the foliage of your plants with compost tea to prevent disease. Scientists aren't in agreement about whether or not this is effective, but they don't say it can hurt, either.

Tips and Warnings

  • The USDA warns that adding meat or fish to the compost tea can allow e-coli or salmonella to grow, causing the germ to spread to garden vegetables and, subsequently, the people who eat them.
