Westeria not in bloom?

Why won't my westeria bloom ? It's in full sun, PLease help. It is heathyWesteria not in bloom?
Grafted wisteria plants flower at a younger age than cuttings or seed raised plants, so if it hasn't yet flowered, its type of cultivation may have something to do with it.





Pruning can also help Wisterias flower more profusely, as slowing sap down in a plant does encourage buds to form. Whilst they may ideally be pruned a couple of times a year, I would focus on its mid/late summer pruning, around August is fine, cutting back new shoots by a good third, to around 12'' in length. Generally sidewards growth, slow sap movement, and multiple branches out from a main stem will all encourage flowering.





You can prune in spring too, just beware of damaging, or knocking any buds off from your plant. Shorten any late summer growth whips - you can distinguish flower buds by their fatter appearance.





As your plant is healthy, and as Wisterias can grow masses of leaves, I'd be wary of fertilising with anything other than Sulphate of Potash (Potassium Sulphate), as a mixed fertiliser will contain Nitrogen etc, which will encourage green growth - and I'm guessing that you're getting enough of this. Potassium is the element needed by plants to create flowers. and is provided by this nutrient, which you can pick up at nurseries etc. It may not be required, but shouldn't do any harm.





My other thoughts, as yours is growing in full sun, would be to mulch your plant, to help ensure that it doesn't suffer from drought during excessive hot, dry weather. I'd do this in spring time, or now if not already done (assuming you're in the northern hemisphere). Obviously, you could also water during periods of extended drought.





Otherwise, all plants, like us humans, are individual, and can be fickle. As you've generally got a healthy plant, part of the issue may just be down to how it was propagated, as well as its own fickle nature. But, continue your TLC and you're likely to get results. My mum had a white Wisteria that took over 10 years, but then became a super performer - it wasn't grafted, and this led it be slower off the mark.





Hope this helps. Good luck! RobWesteria not in bloom?

several reasons why wisteria may sometimes not bloom. If it's a young plant, it may not have developed yet to the point where it will bloom. Usually though, drastic changes in weather can be the culprit. If wisteria is preparing to bloom and a cold spell comes along, it will prevent the blooms from appearing...the entire season. A drought will also prevent blooms if it's severe enough. Normally, unless it's in a container, there are ample nutrients in the soil for proper blooming, so I don't think that would be the problem.





Anyway, good luck
I planted two wisteria twigs at the same time. One grew to 35 feet high, eventually, but did not bloom for the first five years. It is in full sun. It has spectacularly full years, usually followed by light bloom the next year.





The other I planted in full sun beside a driveway. It is only six feet tall and has never bloomed. No one believes these started out the same, but I guess site matters.
Wisteria is a fickle plant.. it can go a season or more before it blooms, so be patient with it, try a bit of fertilizer suitable for these plants and wait. You will be rewarded with the most spectacular display...
