I have a beautiful Japanese Wisteria that I have trained to grow up in the corner of my backyard and then onto the top of my privacy fence. The past couple of years, it has sent up suckers along the base. I cut them every 2 weeks but it seems that if I cut 20 one week, 40 show up the next week. Is there any way to reduce the abundance of these suckers?
There's nothing much you can do but keep cutting.
My son bought the vine approximately 5 years ago with flowers, but it never bloomed again after that. It is near a tree, but not under. It is out in the open. I have not really pruned it. Would that be some of the problem? It is a Japanese wisteria. I live in Pittsburgh.

This plant is on a south facing pergola and the blooms used to be prolific and gorgeous. The last few years they are pitiful and few. What can I do?
The soil may have too much nitrogen. Try to offset it with some phosphorus, like bone meal, to help promote more lush blooms. This article should also help: https://www.gardeningknowhow.com/ornamental/vines/wisteria/wisteria-blooming-problems.htm

My Japanese Double Dragon wisteria is turning yellow and the leaves are spotted. It has an arbor that it's growing on but it seems to have stopped growing. We are in the San Francisco North Bay and our temperature is mild in winter (it doesn't get lower then 47 at night and stays around 60 at the lowest during the day in the winter). Can you help me?
It sounds like it may have a fungus. Treat the plant with a fungicide. I like neem oil myself, as it will also deal with any pest issues the plant has and it is safe for people and pets. Here is more information on it: https://www.gardeningknowhow.com/plant-problems/pests/pesticides/neem-oil-uses.htm
Japanese wisteria flowered but didn't send out new shoots afterwards. It has flowered for the last 3 years but this year, for the first time, it has not sent out new shoots after flowering. Every other year the new growth has been very vigorous.
I can't really locate any issues that directly would correspond with last of twiners forming.
