Overgrown wisteria management
I've just moved into a new house with an overgrown wisteria tree that has grown in to an adjacent blackthorn tree and also climbs up the back of the house. As you can see in the pic there is a lot of wispy growth on the top of the tree and also at the base. There are lots of bud so hopefully will flower well. My Q's are: Should I cut this wispy growth back hard at the end of summer? Should I worry about it growing in to the blackthorn. And can I cut the growth on the house back with a hedge trimmer or do I need to use pruning shears so each branch is cut to the correct length? Sorry for the long message!
