Is horse manure only harmful as a boarder in my walled garden
I have just put in a boarder bed in a wall gardened area. It mostly consists of aged horse manure. I am afraid that it isn\'t enough do I need to add soil. I have being mixing in soil in the hole that the plant is going into. I hope that I will get flower and not all leaves what else can I add to have a balanced bed.
You can't use mostly aged horse manure. You need a higher ratio of soil to horse manure. Perhaps you can remove some and use it elsewhere, and augment the current bed with soil.
