Wisteria gets plenty of sunlight and water. No bugs. Should I fertilize? If so, which would be the best to use? Plants are about 3 years old and are planted in the ground. Thanks.
Leaves can turn yellow for a variety of reasons. This article can help you pinpoint what might be affecting your plant:

Fertilizing may help. Use a balanced fertilizer (e.g. 10-10-10 or 20-20-20).
I have tried to dig it up and replant it elsewhere, but it continues to grow in same spot. It has grown under my sidewalk and actually moved it. The bush has been there for over 30 years. What kind of herbicides can I use? Also, I have dug up most of root system I could get to without taking up my sidewalk and stairs. It is tearing up my house. Please help.

I planted two wisteria at the base of an arbor last spring. It was a beautiful plant all summer and climbed and twined on the arbor. I was looking forward to seeing it flower this year. However, the bark/stem is brown and there is no sign of even leaf buds. The plants came from a farm store garden center. The plant was in a gallon container. It is called a Wisteria macrostachya "Aunt Dee". It is labled for Zones 4-8, and I live in Zone 5. I did not do any pruning at all. Is my wisteria still alive? Will it bloom this year? Is it late to break dormancy?
Some varieties do break late. This article can help you figure out if it is budding late or is dead:

The first year for plants, even when they are planted in the right zone, it a hard one. If they do turn out to be dead, try planting again and give them plants extra protection in the winter the first year they are planted.
My wisteria has cream to brown patches all over it, and has started to die off. There aren't many blossoms. HELP!
It sounds like it has a fungus. I would treat the plant with a fungicide, like neem oil or copper sulfate.
