Of course, in the world of retail, poop seems to be a strong if not offensive word. Hence, renaming it into Soil Secret seems to be more enticing and that is precisely what this Pennsylvania-based company christened there product which is carried by online vendors like Gardens Alive and Dirt Works.

Obviously used as fertilizer, Soil Secret is a good source of nitrogen and other plant nutrients and is mild enough that won’t burn roots as a fresh load of chicken “castings”. A bit expensive but you have to consider how they can manufacture such helpful fertilizer to fulfill a growing demand for it. In short, you also have to consider the worm breeding process.

Even better is a garden with rich, organic soil that’s ripe with earthworms to give you free poop on a daily basis. Worms also help break down organic matter in the soil and aerate the soil with their tunneling. If a dog is man’s best friend, a wad of worms is a gardener’s best friend.
Three worm enemies are pesticides, regular tilling and cold, wet, clay soil. It can take the earthworm population years to recover from annual chemical onslaughts.
