It IS hard to find people to do the 'detail work' that gardens usually need.
I agree, lawn mowing is pretty unskilled, that is part of the appeal of lawns to many people.
Yet here I keep adding gardens, trying to reduce my lawn footprint.
But I am going to do more mulching, to reduce my weeding and mowing. Mulch for paths under trees, and mulch any bare ground between my chosen plants.
