Of course, we know that earthworms are very beneficial.  They aerate the soil.  They make channels in the soil which improve absorption of water and drainage.

But…

Did you know that earthworms have a much greater impact on the soil?

The waste left behind by worms, called worm castings, have many beneficial effects on the soil and the plants that grow in the soil.

Here are a few:

  • It supplies organic matter to the soil.
  • It helps the soil retain moisture.
  • It reduces the density of soil.
  • It helps the soil to retain nutrients longer.
  • It aids the growth of microbes in the soil.
  • It supplies beneficial microorganisms to the soil and plants.
  • It allows the plants to utilize nutrients more effectively.

Because of these properties, worm castings make a good soil amendment in flower and vegetable gardens.

Here are ways that worm castings may be used:

  • As an additive when planting in the garden – Put ½ to 1 cup worm castings in the hole as the plant is set out.
  • As an additive when planting potted plants – Make a mix of 10-20% castings with potting soil to use with potted plants.
  • As a medium for germinating seeds – Make a mix of 5-10% castings with seed starting mix or line your furrow with castings as you plant in the garden.
  • As a side dressing for annuals and perennials – Mix castings into the soil around your plants at the drip line of the plant and cover with mulch.
  • As a tea for plants – Mix castings in a 5-10% ratio with water, steep overnight, and then either water or spray on plants.  You may leave the castings loose or put in a tea bag.

Since there has been a good deal of community interest in this topic of vermiculture, Mary Ann will be partnering with the Haywood County Library to present a free workshop on “How to Build a Home Compost Bin with Worms.”
