A neighbor said there is a correct way to shape my hedges when trimming them… what is it?
BOB: The key to trimming hedges and other ornamental plants is to ensure sunlight can reach the lower branches. Many plants tend to grow wider at the top, reducing the amount of light reaching the lower branches and causing them to thin-out or become bare. To trim hedges the ‘correct way’ keep the bottom branches as long or longer than the top branches.
