I’ve recently made some banana fertiliser, I done this by putting cut up banana skins in a pot of hot water and allowing it to sit. I know the longer the better:) I was wondering if anyone could tell me, if I take old dry potting soil/soil and I adequately water it add egg shells and food scraps as well as a used teabag will I revive/rejuvenate it and add add nutrients back into the soil?? Will I be able to grow my plants in it? Any and all help would be appreciated
