Live in Zone 6 My wisteria (now about 5 years old) has always bloomed- not well though. It is absolutely huge but again, not a whole lot of blooms. This year, it is even taking a while for the leaves to come out (still not completely full and it is June 9). I trimmed it back quite a bit in spring (probably about end of April). Any suggestions? I have fertilized it once - last week.
I am in zone 6 - I think it is early spring that it is to be prunned here. Maybe I pruned it too late in the season?????
You can prune out most of the flower buds with winter pruning when done incorrectly. Did a quick Google and came up with this as a guide -with pictures- of how to properly prune Wysteria....
Thanks for all the great websites. I have read them all. My only concern is that they never tell me which growing zone they are referring to. They say winter, fall, summer - whatever but wouldn't the zone be important?? I am in zone 6 so don't want to follow directions that may apply to another zone. The way I see it is that (FOR ZONE 6) I can prune any of the wild runners anytime during the summer. Then in the fall (Oct) when the leaves fall off I can prune back to 3 buds from main branch. Then in February I can prune further back if needed. I am fearful that I don't understand which branches will be the ones that hold the flowers. My Wisteria is huge and on a high trellis (about 10 feet from the ground). The branches are all tangled- which is what I wanted as I use it as shade on my back deck which is in full sun all day. Man, this is a lot of work. I guess it serves its main goal to give me shade but I had always imagined that some day I would have beautiful bunches of blooms hanging down overhead. I have had some in the past but nothing like some vines I have seen elsewhere.
