So I think we have a verticillium wilt infection. 😞
Any other gardeners in the fediverse have experience with this?
The back story: several years ago we planted a pair of laceleaf elderberry to frame our front door. One did lovely, the other didn’t survive the winter so we replaced it. The new one did fine until suddenly it didn’t. We replaced again, and this one thrived, budded this spring but then promptly wilted before they were fully open…
