We need some advice regarding pruning our hedge around the house. The hedge is a Texas Privet, 25 years old and 8’+ high – I trim it to 7 ½’ every other year. It’s about 6’ thick. It goes all around the yard and is 228’ in length in total. My wife wants to prune it to stimulate new growth. (1) What kind of pruning would you recommend? (2) What time of year should we have it done (or not done)? [Notice the old BBQ to the right to gage the height of the hedge]
