I have a ditch at bottom garden, (approx 20m long 1/2 metre wide and deep, there is a little water 2 or 3 inches in winter, it seems to be fed partly from the ditch extended up to next doors garden and some seeping along ditch. I wanted to fill ditch and grass over (easier to maintain) Can i fill ditch with gravel and then top soil and grass? Ive heard of french drains and soakaways. Any advice appreciated.
