When hedges such as camellias or lilly pillies are in active growth during the warmer months of the year, Don recommends pruning every 4 weeks or so. Regular light ‘haircuts’ keep hedges tidy and prevent them getting out of hand. If you wait too long before you prune, your hedge will start to look scruffy and it will become difficult to manage. You’ll then have to do a full renovation prune, which means spending a lot of time setting up string lines and trying to work out where to cut.
Don’s tip: save work and time by pruning hedges more, rather than less.
