Why won't my wisteria bloom?

Question

I live in south Florida, and have had my wisteria for at least 7 years. When the hurricanes hit in 2004, my wisteria was cut all the way back (it was only like a year old or so then). It is very healthy, great foliage and strong vines. It just does not bloom, never has! I was worried because of the zone I am in (9-10), but I have seen blooming wisteria around here. I have heard it may take 8-10 yrs to bloom. I have also heard that I should prune it. But, when you go up north Florida, like Gainesville area, you see it growing wild high up in trees. I know that is not pruned. Any suggestions? Thanks so much!

Answer 1

Provided your wisteria is getting plenty of sun, it sounds like it may just not be old enough to bloom. It can take up to 15 years, unfortunately. I've got a pink flowering variety and last year (at 9 years old) it flowered one lone bloom cluster. The following site gives some good tips on how to get your wisteria to bloom (if it's old enough):

The age a wisteria will bloom may vary from plant to plant, and this is especially true of one started from seed. It's possible your plant may not have been vegetatively propagated, and if not then it may be years yet before you see blooms.

Sounds like your wisteria needs a dose of phosphorus to jump start the blooms. Wisteria can take 8-10 years to bloom, but by 7 years the wisteria should be blooming if the soil conditions was supply the plant with everything it needs.

This article will tell you how to apply a high phosphorus fertilize to force your wisteria to bloom, and also has some other great care tips for wisteria.

Answer 5

Wisterias are weeds and will take over if you are not careful. They can destroy houses and outdoor structures if not kept in check. They flower on the previous year's growth, so they benefit from a hard pruning in the early summer, then allow them to grow over the summer. Trim back the new growth in the late summer to keep it under control, but don't remove all the new growth. They can take several years to start flowering, but 7 years seems like a long time with no flowers at all. They like strong sunshine and do not need any fertilizer.



Some wisterias will just never bloom...they are sterile plants and nothing you do will get them to flower.

I've had the same problem, they seem to be very temperamental plants. I was told that you should buy a Wisteria when it's already in bloom and that guarantees it'll bloom next year. If your garden centre has a horticulturist, it might be worthwhile to pick his/her brain!
