What This Is
Earthworm castings crafted by BuildASoil in Colorado, processed carefully to keep the biology intact. They improve soil structure, hold moisture better, and raise overall fertility.
How To Use Them
Compost tea: 2.38% by volume, which works out to just under two cups of castings per five gallons of water.
Soil building: 15 to 20% castings in a potting mix for vegetables or any heavy feeding annual flowering plant.
Top dress: use them liberally at any point in the plant’s life. One to two inches makes a good layer.
Sizing
Available in two gallons or half a cubic foot.
