Pruning a Pyramidal English Oak
My tree is too tall and I want to cut its height (topping the crown, I think it is called?). When is the best time of year to do it? Can you recommend some strategies on how to top it off? I live in southwestern Ontario (Canada) not far from Toronto. Thank you.
No legitimate arborist will top a tree. It is not healthy for the tree and the results are spectacularly awful. This is particularly true of pyramidal trees. (Use your search engine to check images.)
Have a professional arborist, not a landscaper, come over and talk to you about what can be done for your tree. Because oak wilt disease is a significant threat, major pruning should be done in winter.
