How old does my wisteria vine have to be before it starts blooming in the spring?

This is the 3rd spring I've had it and still no blooms. Any suggestions?

Yah, sometimes they are a little slow at blooming. You need to root prune the thing. Get a shovel and make a circle all around the plant to cut the roots (look it up on the web) about a foot out from the trunk of the plant. You can also apply super phosphate.
Reply:I was told it takes about 15 years you are better to get a pice of one already with bloom
Reply:I had bought a wisteria before %26amp; did read in the magazine Birds %26amp; Blooms that wisteria can often take 15 years to bloom. I tried to root-prune it, gave it high phosphorous fertilizer-bonemeal, etc. No luck. I solved it simply by going to my local nursery when wisteria is blooming %26amp; simply bought 1 that was already in bloom in a plantable pot(it's somewhat like cardboard %26amp; dissolves in the soil, a peat pot, I think it's called.) Every year my wisteria blooms %26amp; has secondary blooms throughout the summer. You may want to seriously consider getting 1 in bloom next March/April.
Reply:Mine was in the ground for 5 years before it started blooming. The 1st time it bloomed in only had a couple of blooms on it, but the next year it was really pretty.
Reply:The first year it sleeps, the second year it creeps, the third year it leaps. It might still be in the growing stage and not yet ready to bloom. Wisteria and other vines often spend their first few years putting all their energy into growing deep roots before they flower.


Have you fertilized it at all? You might want to try fertilizing it this year with a balanced (15-15-15) fertilizer for all around growth, and fertilizing it next spring at the first sign of leafing with a fertilizer designed for flower blooms.


Give it time to grow up and out. It may be in the juvenile stage for a little longer, but it may surprise you.


Good luck.
