Last September I shared the sad news that one of my favorite plants had been hit with a nasty disease: verticillium wilt. I watched as my Lemony Lace elderberry (Sambucus racemes) wilted one chunk at a time, and just when it was finally getting to a good size after three years in the ground.
Verticillium wilt is a nasty soilborne disease that affects many plants (here’s a list), including elderberries. Last year I cut off the affected branches, making sure to disinfect my pruners) but I knew when I did it that wouldn’t solve the problem. The only real remedy for dealing with it is to dig out the plant and a large area of soil around it.

Taking that step last weekend was even more difficult because there were lovely fat buds on the branches that I knew would turn into gorgeous feathery leaves. And they would look good for a little bit but it’s likely that they too could succumb to the disease. Or maybe not. According to the Missouri Botanical Garden, the symptoms might not show up this year: “The initial symptoms may occur on only one branch or may involve the entire plant. Oddly, following the initial symptoms, there may be no sign of the disease for several years even though the infection continues to reduce plant vigor.”
There aren’t a lot of good ways to get rid of verticillium wilt once you have it. You can attempt to solarize the soil by covering it with plastic and “cooking it” it several months—six or more, which isn’t a very practical solution in a packed garden. I decided to dig out the entire plant and as large and deep of an area of soil that I could. All of that went immediately to the burn pile.
I don’t see solarizing that area as practical for me, but I’m considering giving it a good burn with the weed torch. I don’t know that that will work, but I don’t think it can hurt.

I have another Lemony Lace elderberry in another part of the garden that was much more immature but by the time I went looking for it last spring it looked like there was a chance it too had the disease. I haven’t yet dug that one out. By the way, I asked the folks at Proven Winners who developed that plant if it was particularly susceptible to verticillium wilt and they said no more than any other elderberry. So I wouldn’t hesitate to plant it if you don’t have problems with other elderberries.
One of the plants that is susceptible to the disease is Viburnum and my garden is full of them. In fact there is a group of three large Viburnums not far from the elderberry I dug out and one was looking not quite right last year. I’m keeping a close eye on it but already I can see it doesn’t have the same flower buds that the others have. I’m crossing my fingers it’s not verticillium wilt that’s causing the problem.
The optimistic gardener would look at this as an opportunity to plant something new in that spot that is resistant to verticillium wilt. I’ll get there eventually, but I’m still sad this beauty had to go.
I killed three Japanese maples in the same spot before I realized it was wilt and not me. Have planted other things in the same spot with no problems. But I have not had good luck in general with Jp. maples. I was trying to figure out if I had a place for that Elderberry and this does make me think twice. Though I think I am kidding myself that there is any room for it!
That's too bad; elderberries are lovely and it's sad to lose something you've invested years in. I wondered if the Proven Winner ornamental elderberries produce useable flowers and berries? Elderberries are extremely popular in Europe for making delicious syrup from both the flowers and berries, and I plan to plant a few in my yard (and cross my fingers that they don't get wilt). Both the Lemony Lace and the Black Lace varieties are beautiful but I want to be sure they will produce a good crop of berries.
I hate it for you to have to dig out your well loved plant. Darn the luck. I would be sad too. It is ok to be sad about it. You will get an inspiration for that area. Good luck.
This is so sad.
I just noticed my Lemony Lace Elderberry tree that I have had in the ground has started to shed its leaves. It is now the middle of August. Isn’t it too early for it to do that?
It does seem early, but my guess is that it’s stress. The signs of verticillium wilt are pretty dramatic: just completely wilted one day and then dropping leaves. I’d just make sure it goes into winter well watered and hope it rebounds next year. It’s a gorgeous plant and I’m bummed I can’t grow it anymore.
I know this thread is a year old, but I found it because I was trying to find out what is wrong with my Lemony Lace elderberry. Guess what I found! And your blog is not the only place I’ve read about VW on Lemony Lace. I think that the folks at Proven Winners may be wrong: I’m beginning to wonder whether LL isn’t MORE susceptible to VW than some others. Now that I know, I’m going to plant something in that spot that is resistant to VW. I’ve experienced the problem on my tomatoes as well, so clearly my ground is full of it. 🙁
Interesting! I wonder if you’re onto something with the susceptibility of Lemony Lace. It really is a shame because it is such an outstanding plant in every other regard. Sorry that you had the problem too!
Sigh! All 3 of our black elderberry are dying of wilt. I presume verticillium. Happen to the bushes that are 5 or 6 years old, maybe 7 and are over 7 feet tall. They have been so beautiful until this summer and now seem to wilt more each week that goes by. Am also at war with a fungus that is affecting the arbor verde in spots. Have been cutting out the brown limbs and spraying a fungicide, actually 2 different ones. Like I said, it is a war to save them. Have had some patches of what we believe is a fungus (know not what) in spots in our grass near the elderberries. Any connection? Our virbinium on the other side of the house, the red bud and lantana boxes, the black eyed susans all look fine. But after reading the commentary on the verticillium wilt I am now worried about all of those plants. Did lose a smoke tree, planted as a specimen tree late in summer last year. Seemed to wilt -maybe the verticillium. Live in NW AR so lot of hot weather in summer and fairly dry in July and August, and this year even into September. Any connection to the fungus liking the stress it put on the shrubs? Is the verticillium an opportunistic fungus that lives ubiquitously in the soil? Thanks for any advise.
