Are you referring to sheet composting? It is also referred to as In-place/on-spot composting. Some call it , " In situ" soil building which is a Latin term meaning in the same place or on spot composting where you are going to be planting . Now are you doing this for garden beds, not orchids; is that correct. In this method, you are applying manure, leaves, and crop residue and covering it with landscape fabric. Now I am applying green manure, food waste, leaves, and grass, is that okay, and I don't have crop residue cause it's the first time. Now the other question after the JMS application a month prior is, how long apart do I do this and how long do I let this decompose before planting on the beds. Also, do I have to remove whatever is decomposed on top of the soil, or do I just plant on top of that?
I'm not talking about sheet composing. If the crop is planted and then covered with organic matter for weeding purposes, the crop will not grow significantly.
You can compost with sheet composting. In this method, it is recommended to mix with the soil a lot, cover it for at least 20 days, and then plant the crops immediately.
