|I have a raised bed garden which I've filled with good topsoil in the amount of 24 cubic feet. (6x4x1) I want to use worm castings to jump start it.
Does anyone know how much worm castings would be needed?
|How much castings do you have? You hardly can't overuse the stuff since it won't burn your plants; you can use as much as you like.
If you have enough to add a 1 inch layer and mix it into your soil you'd get a great jumpstart. Any more than that would just be increasing the benefit.
