Please help! Planting Fruit in Sandy/Rocky soil alongside buildi
I'm trying to turn the area alongside my building into an area in which I can plant fruit, namely blackberries.
The soil there is not soil, but it is instead full of rocks and builder's sand.
I'm attempting to dig that out and replace it using a shovel.
I want to replace it with cow manure, etc. so that I can plant my blackberry vines.
My question is, HOW FAR DOWN do I have to dig until I can begin replacing the rocks, etc. with cow manure and other amendments?
PLEASE, if someone could help I'd appreciate it.
I'd just like to know how many inches down I need to dig and remove the rocks, etc before I can begin tossing in the manure and other amendments.
