BigBill said:Wisterias by and large are climbing vines, not trees. When they are happy, some of them send out runners or branches that can spread 5, 10, 20' in a single growing season!!
So in part, it depends on what variety you bought. But in any case, to confine it into a controllable tree is next to impossible.
Unfortunately you picked one of the larger varieties available reaching 25' in height. It is also one of the best Wisterias available in today's market.
DaisyI said:You can train a Wisteria to look like a tree.
DaisyI said:Oh, sorry. I didn't understand the question. I doubt you can separate them because I suspect they are all connected to the same roots. You could dump it out of the pot and check. Wisteria are pretty pliable - I would just braid them loosely together. You don't want a tight braid anyway as they need room to grow.
It may look silly in the beginning but the trunks will quickly thicken and grow together.
