Hi Charles, there is a lot of information about setting up new no dig beds and I am well aware that your advice is “well rotted horse manure with an inch or two of green waste on top”. Would it be a big problem to change the layout to 2 inches of manure and 4 inches of green waste on top? if this doesn’t work would it be better to mix the manure and the green waste together rather than spreading them in separate layers?
Any combination is fine, I like to give ideas rather than recipes.
The main principle is how it’s easier to sow and plant into fine compost, so keep that for the surface layer. It may be old animal manure. Any kind of manure is possible, often they have different qualities, also arising from the bedding used.
Mixing is an option of you want to, it’s just less work not to, and worms etc do it in the end.
