maintenance basic question
This must be the gardening equivalent of 'how to boil an egg' because I can't seem to find a descriptive answer. We have rounded 'river rock' type stone all around the perimeter of the house. Nearby are lots of pine trees, and so lots of pine needles have mixed in with the stone. It doesn't look very tidy, but damned if I know how to get them out -- short of picking them out practically one at a time. Pic below is about 5 years old, but looks much messier now.
