Hi! So, I am located in Colleton County, (Low Country) South Carolina. A neighbor had a bunch of wild wisteria, in the wooded area behind their house, that was not purple but instead, a white with a soft pinkish tint to it. Last summer, I dug a small piece up by the root and pot planted it. It took and grew a bit during the following months, then reverted to what looked like a small dead twig during the winter. It came back strong this summer and even bloomed a couple of times. I want to keep it in the pot on our porch and train it to be a small tree. It's time to prune but I am nervous.. Can someone recommend where to clip this so that I don't destroy it? Thanks so much!

Hello and

Waving at you from neighboring Charleston County.

Wisteria is a thug here, and presumably there also. You are not likely to kill it. Your neighbor's wisteria is probably not 'wild' as in 'native'; there are native types of wisteria, but it's fairly rare and your neighbor's plant is almost certainly an Asian wisteria running wild.

There is info here about training wisteria into a tree form, but you'll need to scroll a bit:

Good luck,

Let your wisteria reach the desired height before pruning. When it reaches it, just cut the top tip off at the first node.

Wisteria are vines and can't support themselves to form a 'tree', they need support.

The plant database has a number of "tree" wisterias, but this is one of the clearer photos:

It requires a little time and patience to train them to grow this way, but it can be done, and can be very pretty. If left untended, it will still leave seedlings all over the place, and unpruned branches will reach out to anything they can climb on, and become a strangling vine with a very stout base.

I guess it depends upon how tall you want your 'tree.' If your wisteria flowers are as long as mine, your tree has an 18" tall trunk.

Wisteria shrinks as it grows. If you let it get a grip on your porch railing, it will easily pull it down. That would be my main concern when I was trimming.
