Wisteria leaves are dying at the ends and no new growth. We planted a wisteria 2 years ago. It was healthy then. It is in full sun. Now the leaves are turning yellow at the ends and it looks as if it is dying. We are only at the property for about 6 months of the year so wonder if it's lack of water.

I would check for crown or root galls. Here is some information on them that may be helpful: https://www.gardeningknowhow.com/plant-problems/disease/how-to-fix-crown-gall.htm
If that doesn't turn up anything, it may have a fungus. Treat the plant with a fungicide. I like neem oil, 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/problems/pests/neem-oil-uses.htm
