How to Assemble a Worm Composter
Worm composting transforms leftover food scraps into valuable plant food. And it can be done year round indoors.
Attach a length of plastic tubing between the aquarium pump and a three-gang valve. Attach three pieces of plastic tubing the other side of the gang valve, making sure they are long enough to reach to the bottom of a 5-gallon bucket. Attach air bubblers to each of the three pieces of tubing.
Fill a piece of cheesecloth with enough compost to fill 4" of the bottom of the bucket. Place the compost in the bucket, making sure the three bubblers are underneath. Fill the bucket with dechlorinated water almost to the top. Add 1/2 cup unsulfured molasses, which will feed the bacteria in the compost.
Plug in the pump and turn it on. The compost tea needs to brew for two or three days and should be stirred occasionally. The tea should have a pleasant, sweet odor. When it is ready, turn off and unplug the pump.
To use as a foliar feed, strain compost tea through a coffee filter into a sprayer. Spray directly on plants. To use as a soil drench, place the unstrained tea in a watering can and pour it around the base of plants.
