Some of the wisteria branches are getting so big and heavy they are too heavy for the arbor. What is the best way to cut these back so we can reinforce the arbor? Most of these are the main branch. The plant is about 12 yrs. old and blooms every year. I've always kept it trimmed back but not the heavy branches resting on the arbor itself. Thank you for any advice you can give me.
