I have very small buds on my wisteria which are not developing and are falling off. I only have a few blooms at this time. Last year my plant was covered in blooms. Is there a reason for this? I did do some pruning but not harsh.
Buds dropping or falling off can be due to insects or environmental issues.

If a wisteria vine is going to bloom, when does that happen?
Chinese Wisteria are spring bloomers, Japanese Wisteria is summer blooming and the less common American Wisteria are late summer bloomers.

I planted my wisteria 5 years ago. The 1st 3 years it blossomed beautifully. Last year and this year it produced copious buds, but they have failed to flower.
Here is some articles that will help you - one discusses the possible reasons wisteria buds do not open and the other why wisterias do not bloom:

I don't have a pergola and don't really have a place for one but I would like to get a wisteria plant. I can put it on the side of my shed but what would I use for support?
Here is a link to a website which will show you how to grow wisteria along the side of your shed using galvanized wire and brackets:

I may have hurt our wisteria. It has been growing on a pergola for quite a few years now. This year, there are very few blooms and the whole tree has very few leaves as well, with many of them looking dried up. Last fall I cut down a spruce tree in the yard and piled the branches under the pergola with intentions to burn the branches in a nearby fire pit soon. Unfortunately, the branches sat under the pergola (next to and under the wisteria) until today, when I finally removed them. In addition to that, as I was removing the branches, I found a strange white foamy substance in the pile all the way down to the ground covering about a 4' diameter. The foam didn't appear to be insect larvae but more like some kind of fungus perhaps. Do you think the ground has become acidic due to the spruce tree branches being there and do you think there is concern about the foamy substance?
I would suggest having a soil test done on the area you are concerned with.
Your local County Extension Office can help with this.

This spring in Zone 5 my wisteria is looking totally bare, no leaves or blooms. The wisteria is at least 18 years old and has been growing on an arbor. Early last fall I pruned the vine, but this winter I did not. Yesterday, I found two green buds that look to be growing. How should I prune the wisteria this year if it is still looking very bare, no growth showing? I want to know if it is dead or dormant.
This spring has been a rather cold one for most of the US. And that has kept some plants dormant longer than they usually are. As long as the branches are pliable and you are seeing signs of green growth, the plant is still alive. It is just taking a little longer to wake up, is all.
You can go ahead and prune it now or you can wait until you see more growth. Wisteria will tolerate pruning at almost any stage.
My twenty year old wisteria is large and has bloomed for the last thirteen years. This year there is no sign of growth. I am worried it has died. Do they ever go dormant?
Your Wisteria could just be delayed this spring.
Check the branches and bark. Do the branches snap and break or bend?
Scratch the bark. If you see green, it is still alive.
Dead wood appears tan or brown under the bark.
