how do i make a wisteria plant flower?

Welcome autumnkat07gmail.com. So sorry you are losing your trees. Are you watering them? Climate change is doing some numbers on trees across the nation.
How old is your wisteria? Tree or vine form? Some won't bloom for several years and you have to give them the right conditions. Hope this helps.

So... native wisteria? Or one of those horrible invasive oriental wisteria?

If it's heating up there... if the humidity is increasing, you may be seeing some of the fungal diseases that we suffer from down here.

My pear trees get fire blight, my plum trees get other stuff...

Here's a site discussing cherry diseases:

When I lose fruit trees... I try another fruit.

My mulberry trees seem problem free... My elderberries grow very well... American persimmon... yes... japanese persimmon... not so well...

loquat? Fireblight took them.

Blueberries=too dry... farkelberries and deer berries do well...

Lots of fruit to try... don't give up.
