Castings are very rich in nutrients and trace elements and are excellent in holding moisture and water (2 to 3 times their own weight) enhancing both the plant and the soil while reducing watering needs up to 50%! They also contain beneficial micro organisms and bacteria that continue to thrive, grow, and reproduce once spread on your plants or soil. These qualities provide the growth and boost that plants need and help suppress various plant diseases such as bacteria, fungi, nematodes and harmful plant pathogens while enriching the soil.
Worm castings will never harm your plants or grass and it's virtually impossible to overuse. Castings are natural, environmentally safe, odorless and will not harm your children or pets and will never "burn" your lawn like chemical fertilizers. They make an excellent indoor plant fertilizer as well and increase germination rates and seedling development.
Lab tests have shown that castings contain approximately 7 times the phosphorous, 11 times the potassium, 5 times the nitrogen, and almost twice the calcium than regular soil.
We are very careful in selecting the best food sources for our worms and the processing of our worm castings are filtered down to a screening of 1/8th of an inch elminating all but pure castings. Pure castings will appear almost black in color and resemble coffee grounds.
