I've been lurking on this site for a few days and readings lots of great information. You all have beautiful gardens. I have a few questions that I will post seperately...I'm in zone 4b/5A in Moncton, NB
I have a large wisteria vine that was planted 4 summers ago. I believe it's the floribunda type with purple flowers. It is now huge...about 10 feet tall and 4 feet wide of green leaves. Totally out of control!!I have it climbing on a sturdy trellis on my pront porch. I prune it a bit in the summer and more in the winter. It has never flowered. It gets sun all day long. I read that you shouldn't fertilize so I haven't for the last 2 years. I also read recently that I should be pruning heavily twice a year. I think I'm not pruning enough but now I don't know where to start, it's huge. I have a main large stem about 3 inches and 1 foot higher it quickly branches out in 2 large branches (hopefully you will understand . I also have some suckers at the base that are twining around the main stem. What should I cut? If I cut aggressively, will it be worse next year with new shoots everywhere? Also, has anyone had success with rooting the trimmings in water?
Thank you Tanya
