Hi Peter! I have an elderberry bush doing poorly this year, about half of it started leaf blossoms and then they just stopped…looks dead or severly stalled out.The other half is doing much better but I have noticed some new growth branch tips going limp. I’ve had the plant for 3 or more years now and it gets sun at least the first Half of the day. Any thoughts?
It sounds like verticillium wilt…not good. HERE’S a link to more on that. No chemical treatment. Make sure that mulch hasn’t been piled against the stem of the plant. Getting some Bio-tone food into the soil may also enhance the plant’s ability to fend off the disease.
