Yep. Full sun. And don't baby it.

Elly:

Yes, it does best in full sun.

If your wisteria is a named selection (always budded rather than grown from seed), it could bloom within 2-4 years from the container.

But a seedling wisteria requires more than four years to reach blooming size. Usually, it's in the 7-17 years range.

Also note that wisterias require good pruning to encourage them to bloom and continue to bloom additional years. I find the best bloomers are those that are pruned very much as are grape vines. It's a matter of pruning off the extensive vegetative growth each year and keeping the stronger growth that produces "spurs" (short stubby branchlets with condensed buds).

Thank you so much for the info. Would you suggest then that I move it to a more full sun location? If so, how easy is it to move?

Yep. Full sun.

My son had a wisteria for several years and complained it never bloomed. He was waiting until late summer to early fall to prune back the wisteria that was growing out of control. When I convinced him to prune it back in the spring after the neighbors had bloomed, and leave it alone in the fall, it bloomed every year. Al

The answer to that is usually: It was planted in a spot that is too shady; it was not pruned twice per year; or it was propagated by cutting from a non-flowering parent. Modern wisterias should be grafted. Walls facing south or west are the best areas for planting wisteria. They need lots of light and sun. The soil must be rich; if it is not, you should amend it with well-rotted compost. Finally, pruning is important. Tie in all the stems you need to extend the plant where you want it, and snip off the rest of the stems to about finger length. Cut right above a bud. You do this around January time. Six months later, about July, you should prune it back about one foot. Then, the following January, you take it back to finger length again.

Feed your wisteria once or twice per year with a high potash food. You can use rose fertiliser; it is rich in potash. You could feed once in February; and then again in June. It really depends upon where you live and how fast your plants start to come into active growth after winter dormancy. It also depends uponw which type of wisteria you have: wisteria floribunda or w. sinensis. It is late spring for Chinese wisteria (w. sinensis), or early summer for the floribunda.

If your wisteria still does not produce much, I would think about replacing it. It probably has not been grafted. You could get one that is, and you check this by seeing if there is join somewhere along the main stem. It looks like a knobbly joint a few inches above the surface of the soil. Grafted ones have proven their flowering and will continue to do so with the right care.
