How much do I trim a wysteria plant?
How much should I trim my wysteria plant. It still has leaves, but lots of tiny 4" long branch spikes growing out of the stems. It is in a large pot and I am wondering if I should cut all of these spikes or leave them alone. I want to hopefully have flowers this year. Thanks for any answers I live in LA area in Calif, so not much rain, It is in full sun

You can trim a wisteria as much as you want, they are quite hardy. It takes them a couple of years to flower. Prune wisteria in late winter. Remove at least half of the prior year's growth, leaving just a few buds per stem. If you want a more formal appearance, prune again during summer, after traditional flowering. For more blooms, try cutting back the rampant shoots every two weeks during the summer.
