Q.Help – Questions Re: Wisteria Replanted; And Can A DuraWood Trellis Be Strong Enough To Withstand Its Wisteria Vine Growth?
I have a very old wisteria plant that used to be in my mom’s garden. She passed away in 1993, and I brought it home with me. After 10 years, it flowered for the first time, to my surprise. It took root near our front porch and I loved it. We recently relandscaped out front yard and the landscapers recommended I love the wisteria, because it’s root system might be too invasive for the landscaping that was planned for our yard. It’s been in a large wooden pot, but the roots when right through the bottom and had made its home in the ground. Once it was removed from it’s happy spot, we moved the pot to our backyard, but haven’t found a good place for it. In fact, I’m afraid it might be dying since the roots were severed. My husband thinks it’s just going dormant, but I think it’s dying. 1. How can I tell the difference between whether the wisteria is dying vs. going dormant? 2. If it’s dying, how can I save it? 3. We have a Durawood trellis. I originally wanted to use it for the wisteria when we had the trellis built, but people told me the wisteria would damage the trellis. Can Durawood withstand Wisteria vine growth? 4. The trellis is grounded in our concrete patio. What can we do to train the wisteria to climb over the trellis? And is best to somehow get the plant into the ground? I really want to save the wisteria, because it is a wonderful reminder of my mother, so I’d love to hear how I can save it and put it in a place that I’ll see every day.

If you think the plant is fading, getting it into the ground would be the best thing. Find a place away from any structures so you don't need to worry about the roots. Also, give it as much sun as possible. Pruning twice a year will keep the growth in check and stimulate blooming. Unless the trellis is pretty thick wood, it likely won't hold for many years.
