How to Add Worms to my Indoor Plants


Worms provide nutrients to indoor plants by digestion organic products; the waste from the worms, called casting, is very rich in nutrients. Adding worms to indoor plants enables you to avoid using commercial fertilizers. Indoor plants tend to grow faster and produce more blooms or crops after you add worms. The cost of worms is less than commercial fertilizers and chemicals for your indoor plants. Worms are easy to take care of and maintain.

Step 1

Place the container on top of a piece of fine mesh screen. Use scissors to cut enough screen to cover the bottom of the plant container.

Step 2

Load a hot glue gun with a glue stick. Plug in the gun. Squeeze a thin layer of hot glue around the bottom of the potting container. Place the screen on the bottom of the container and allow it to dry for several minutes. For pots that are already planted, have someone hold the container for you during this step.

Step 3

Rinse the eggshells. Allow them to air-dry for several hours on a paper towel at room temperature. Use a meat tenderizer tool or heavy wooden spoon to crush the eggshells into fine pieces. Place the eggshells on top of the soil in the container for your indoor plant. Use a dinner fork to gently rake and work the eggshells into the potting soil, without disturbing the roots of the potted plant.

Step 4

Mix 1 cup room-temperature coffee with 1 cup room-temperature water. Pour this mixture onto the soil at the base of the indoor plant.

Step 5

Purchase red worms at a bait store, or dig worms from your yard. Place the worms at the base of the indoor plant on top of the potting soil. Shine a flashlight on the worms to encourage them to burrow beneath the soil.

Step 6

Add eggshells (see step 3) weekly to the indoor plant container. The eggshells help the worms digest their other food. Finely chop or crush other food items to feed the worms every other week. Items such as banana peels, stale cereal, old bread or coffee grinds provide good food for worms.

Step 7

Check the soil daily for moisture. Keep the soil moist, but not soggy. Water the plants with room temperature tap water or with coffee mixture (see step 4).

Tips and Warnings

  • Avoid feeding the worms acidic foods or using acidic soils. Check the planting container monthly for overcrowding of worms. Remove excess worms and add them to other indoor plants or the outdoor garden.
