How To Use Worm Casting

To use worm castings effectively, you need to know its true potential. Although it is very rich in minerals, it does not actually burn the plant unlike very concentrated fertilizers. Worm castings also contain organic materials that have been processed by bacteria in the worms, making them readily absorbable.

The castings are also known to contain toxins which are harmful to microbes that can cause rot and other plant diseases. Worm castings are also known to help stimulate plant growth even in small amounts. With that said, here’s how you can use worm casts effectively:

Step 1: Use It As A Set And Forget Fertilizer

Since you cannot put too much worm castings on you plants, even the average home gardener can easily use it on flowers, fruit-bearing plants and herbs. You can use the worm castings by sprinkling it around the base of the plants and you can also put it inside the pot.

If you want to make sure that it will be absorbed by the plant, you can dig in lightly around the plants using a garden hoe or trowel. If you need to use it on a large area, you can use a garden spreader so you can easily fertilize orchards and several rows of plants in your area. Use a shovel to dig around trees.

Step 2: Use It As A Liquid Fertilizer
