earthworm castings for indoor plants Wiggle Worm Pure Worm Castings, 30 lbs

100% Organic. Wiggle Worm Soil Builder™ controls all aspects of the worm's environment 24 hours a day, 7 days a week and 365 days a year which eliminates all variables that could affect pureness. This level of control produces a pure, consistent product that can be used as a soil amendment and as a fertilizer. The nutrients and microbial activity of worm castings produce a "living soil" for plants to thrive in. As they are truly pure castings, you only need a small amount around your plants, vegetables, shrubs or grasses to see beautiful yields and growth. A half handful around the root zone of a transplant will produce up to 3-5 times the fruit and plant growth. A little goes a long way. OMRI Listed®.
