I have wisteria leaf mottling with no flowering but dense growth. For 2 years now nothing but yellow and green mottled leaves. Is this treatable? And HOW?
Most likely it is a combination of over fertilization and mildew on the leaves. Dense growth can mean the plant is getting too much nitrogen, which then weakens the plant as well as making air circulation difficult. Both of these issues leave the plant open to powdery mildew, which on a wisteria looks like yellowing and mottled leaves.
I would recommend pruning the plant well to thin it out and open up the air circulation. And treat it for powdery mildew as well. If you are fertilizing the plant or plants near the wisteria (like the lawn), stop fertilizing close to the plant.

We bought a house with wisteria growing out back. One of our gardening friends commented to us, "Wow! I've never seen such a trunk on a wisteria! How old is that thing?" The base is easily 48 inches around, and some of the vine wraps that go up the arbor are about 11 inches around. Is there a way to tell how old the wisteria is? The house was built in 1955, so we know it's less than 61 years old, but we're not sure of its age otherwise. Thank you. -Gloria
My research does not find any way to determine the age of a Wisteria Vine.
There are reports of vines upwards of 140 years of age.

I have had a wisteria growing in my garden for many years and each year it has flowered. This year it looks dead. The branches have no leaves and I wonder what has been the cause.

There was a mature wisteria on the south -facing side of our house when we bought it 7 years ago. Since then it has continued to grow vigorously and in the last 3 years, especially, bloom profusely. This spring it also bloomed well but the growth of the foliage has been lackluster since then - and we need the foliage to provide shade. Every year I have pruned regularly, but only excessive new growth. Is it time to cut back strongly to encourage more vigorous growth?
Here are some links that will help you pinpoint the issue.

Our 12-year-old wisteria has suddenly started to die from one week to the next. The leaves were all green and within a week the leaves are turning yellow curling up and falling off. This has spread from one or two branches to the entire wisteria. We are at a loss to figure out why.
Curling leaves is generally an indication of pests or disease.

Does wisteria die off once flowered?
Wisteria is a perennial (continues to come back) and possibly an evergreen (lasts through winter) depending on your climate and species. Once the flowers have dropped the foliage remains until winter hardening.
