Why is my wisteria bush not blooming?

I planted a wisteria bush about 3 years ago and it has never bloomed. I asked someone at a landscape place and they said I needed to fertilize it and cut all the new growth off. Well I did that and it still shows no signs of blooming. I really don't even know what time of the year to expect it to bloom. I am in zone sixWhy is my wisteria bush not blooming?
My advice is see what the real authorities have to say about it. Not everyone on Yahoo! Answers has the right answer.

PS I live in zone 6 and have been waiting for 3 years. Then I decided to see what the cause is.


My neighbor 5 houses down has about 40 feet of fence covered with the most beautiful wisteria, I've lived here for over 20 years it's only been blooming for about 10 or 12 years. It is a beauty though.

Wisteria can take its time in beginning to bloom, but once it begins, it should continue. Avoid heavy nitrogen fertilizer around the plant -- it is in the pea family and can grow quite fast on its own. Too much nitrogen will encourage rapid growth, which often leads to giant plants with few to no blooms. Wisteria does need a minimum of six hours of sunlight a day to bloom, and should not be pruned past mid summer--since they set flower buds in the fall for the following spring bloom. Any pruning is best done as soon as flowering finishes in the spring (or for non-blooming plants, after they have fully leafed out.) Unfortunately, it is too late to do anything about blooms for this season, but you can begin work on next year. One method that can work to begin initiation of flower buds for next year, would be to root prune the plant in July or early August. To root-prune a plant, use a straight edged shovel, and dig straight down in a staggered pattern in a rough circle about a foot away from the plant. This should cut some roots (not all, because it is not a complete ring) and slow down the top growth. Often this encourages the plant to begin setting flower buds. You can give the plant a little super-phosphate and let it get a little on the dry side-again trying to slow down growth. Good luck and hopefully, you will see flowers next spring.

Not enough sun. Wisteria requires full sun to bloom well. Is it possible that a tree has grown large enough to cast more shade than it did two years ago?

3 years old is young for wisteria . Nothing to worry about, yet . If this continues , try poking a shovel or knife into the ground, near the outer part of the roots . This provokes a ';Oh no! I'm dying. Better reproduce now.'; response .(I.e. flowers) Report Abuse

The biggest reason that wisterias don't bloom is because they are getting too much nitrogen. This is often true when the bush is planted in/near a lawn. The lawn gets lots of nice nitrogen fertilizer, and the wisteria gets it too. When it has lots of nitrogen, it is not stressed, and is not in any way motivated to produce blossoms in order to produce seed and reproduce - in short - it's TOO happy. Feed it with a fertilizer that has a high middle number (phosphorus), keep lawn fertilizer away from it, and hopefully it won't be TOO long before you see blossoms.





Wisterias usually bloom early in the spring, once the ground has begun to warm up - I'd guess sometime around early May for zone six, but that's just an estimate, as I've never lived in that zone. I had a huge wisteria in zone 7b (Denton, Texas, 30 miles north of Dallas), and it bloomed madly with absolutely no intervention on my part. Having acidic/volcanic soil helps, too, but I've seen wisterias bloom in Waco (zone 8) as well, and it's terribly alkaline there, so that's not a must.





Good luck!
Wisteria bushes need to be grafted before they will bloom. If when you bought your bush it did not have blooms on it, it may not be grafted. This may cause it to never bloom. Also, Wisterias usually do most of their blooming in the spring.
Ibelieve your wisteria will bloom this year or next. Just remember wisteria blooms once every two years. T4
I hate to tell you this, but you might have got a male Wisteria. And they do not bloom. Usually the bloom in the spring.
wisteria is a very slow vine to bloom...most very prolific ones are at least 7+ years old. just be very very patient with it. Just do what your doing and it will pay off....good luck!!
