You also don't have to worry about putting too much casting material into the soil, because it will never burn the roots of your plants or flowers. With castings, however, all the healthy nutrients that the plant needs are water-soluble and can be absorbed right away. Most of the time when you grow plants, soil that's full of fertilizer can burn the roots and permanently damage the plant.

You'll also find nitrates in a very potent form within the castings.While other types of fertilizer or soil supplement can claim these nutrients, they can't claim that they are immediately available to the roots of the plant. Nutrients such as magnesium, calcium, potassium, and phosphorus are practically bursting out of this stuff. Many of the nutrients that plants need to thrive can be found in large quantities within earthworm castings.

When worms produce castings, organic material is present throughout, making it an ideal supplement for barren soil. Have some tough gardening soil that could use some help?
