Particularly I use as fertilizer the residues of vegetables, and fruits that I use when cooking, for example, the skin of the banana serves to fight pests, it is left to dry and is crushed and watered, or when we make coffee, it is also good to water that residue as fertilizer.
You have a tremendous job, the nicest thing is that everything is going very well, I can imagine your happiness when you have everything ready. A hug from Venezuela.
