hello. we have a soil dilemma and hope someone out there can help us out.
two autumn's ago we attempted to sheet mulch a large (future) garden space.
we laid down cardboard, leaves, horse manure, and straw and then covered
everything with a sheet of black plastic hoping it would be ready for the
spring.
over the winter we decided to move elsewhere first and after arriving here
(a year late) we have discovered the area can be best described as "choked
with dense dead grass." the landowner removed the black plastic but we are
unsure if he tried to seed it or not (the only explaination we can think
of). the actual soil underneath it, however is dark, rich and lush.
so our question is do we till the grass under/into it? or should we attempt
to remove the "top layer" meaning the grass and whatever roots we can
manage?
we can't understand why there is a large light-brown rectangle where the
soil underneath is near perfect.
