Pruning Your Boxwood. 1  1. Know when to prune your tree. Prune boxwood shrubs at any time between the last expected spring frost and six weeks prior to the first expected fall frost. 2  2. Use sharp bypass pruners to trim off dead, injured or diseased branches. Prune them off all the way to the base of the branch.
Some types only need to be trimmed once a year. This will save you labour and pruning waste. If you only do it once a year, you should do it in August. You should prune boxwood shapes with pruning shears for hedges. Choose shears of a good quality so pruning stays enjoyable. It is also important to keep the blades very sharp. TIP: If you prune in the rain your blades stay free of scaling, making it easier to cut.
