Some are quite large. Foot by 4 inches. Probably a space that's 10x5, not sure the depth.
Thank you so much for all this information. I'll probably cush all the best i can, put some in a leaf compost & the rest, mix with a fertilizer using Paul Morris method. Truly kind words! I will also add a fertilizer to the burnt area.
I'm honestly just starting. I'm going to be a caretaker for a lady's property & this is the first project.
Wish a beautiful day all.
