Earthworms provide nourishment to soil with their castings, which are a combination of dead earthworm segments and fecal matter. Growing any plant in rich, earthworm-enriched soil improves both the look and the performance of your garden. Using earthworms at home while planting makes for a brief, simple process that requires very little maintenance, especially when you use them in your decorative houseplants.
Fill a flower pot half-full with potting soil.
Dig out a hole down the center of the soil.
Fill the hole, and approximately 3 inches above the soil, with live earthworms and their castings.
Cover the earthworms and castings with about an inch of potting soil.
Allow the earthworms and soil to settle for approximately 24 hours.
Sow two or three flower seeds directly into the flower pot, about 1/4 inch beneath the surface. Flowers like morning glory, moonflower vine and daisies thrive in earthworm-enriched potting soil.
Provide the plant with about a cup of fresh water every five days.
