Although autumn and winter are the ideal times for pruning trees as the foliage is less dense and the shape of the tree is clearer, summer is a great time for getting your trees checked for any signs of damage or disease, rot or pest invasion that may need treatment. A qualified arborist will spot damage or disease, that may escape a less experienced eye, and will know how best to treat it.
It is also an excellent time for pruning larger, mature trees where the excessive weight of summer foliage may be causing undue stress on the branches. Pruning will encourage strong and well-shaped growth in subsequent years, whilst thinning out a heavy, over-dense crown will definitely be beneficial for your tree.
Flowering trees will also be glad of a little summer pruning, once the blossom has died off early in the season.
There are some things you can do for yourself of course: keeping your tree well-watered and checking it regularly for signs of wilt or leaf discolouration. Mulch will help to keep the roots around a tree moist – ask your tree surgeon if they have any available to deliver for you.
