To trim your hedges into an even, beautiful shape, you might want to use strings (or a measure laser) as guidelines. First you get rid of the ”main offenders”, large branches sticking out, then get down to the fine pruning. Hedge sides should be trimmed wider at the base to provide maximum light and sun for the exposed leaves. The hedge should resemble a vase turned upside-down.
So, what has to go? If you’re trimming it down for regrowth you can focus on long branches in the middle whereas if you’re just ”fine-tuning” you can concentrate on shape, evenness and thinning out. Start from the top and work your way downward. Also remember to fertilize the hedge to give it energy and to stimulate further growth.
With these few tips – and a bit of old-fashioned, hands-down work – you should be able to achieve a good-looking, healthy hedge with a minimum of trouble!
