Verticillium Wilt Hits The Rainy Day Garden
However, this spring, I could not deny the problem unfurling. The branches on the left fork of the tree were not leaving out. When the leaves did come, they were smaller sized and then some of the leaves simply withered away.
I planted this tree seven years ago, before my family even officially moved into the home. I was so proud of my selection. There was nothing like it in the greater neighborhood. The bright red color of the foliage was spectacular, especially in autumn.

Verticillium wilt is a soil borne disease. Verticillium dahliae is the fungus that is the primary agent of the wilt. It is a common disease for Japanese maples. Once the fungus is in the soil, you can take steps to kill it by covering the area with plastic (for a long time) and let the sun heat the soil.
I am choosing to pull the tree out as the affected area is substantial on the tree and I do not see a way of keeping the tree alive, nor do I want spores of the fungus to spread to my other acer's.
After we pulled the tree out, I had the husband cut the trunk so I could see the damage.

It was very apparent when we cut up higher on the infected side of the tree. Verticillium wilt is the culprit. Damn.
It's a strange thing, how a tree can become a part of the family. It broke my heart to pull it out of the ground.The humming birds have used it as a perch and resting place. I have noticed chickadee's and bush tits as well. Plus, it gave me a bit of privacy as I would sit on my front porch.
I will not plant a replacement tree in it's place. The front garden is truly postage stamp sized, so in the end, it may look less cluttered without the tree there. However, I will miss this beautiful red sentinel.
Here are some resources for identifying Verticillum Wilt. I will continue to update this post with additional materials as I find them.
Disease Resistant Trees
Damn! I'm so sorry.ReplyDelete
I feel you, Jenni. We pulled out two Acer rubrum from the front yard, both with Verticillium. I missed their shade, but their roots were pretty greedy, so it wasn't as heart-breaking as your Twombly's (such a good tree!). A TON of research on verticillium-resistant plants later, we finally settled on Carpinus japonicus (or tszherzinowii--I'm not going to look up the correct spelling!). Super happy with them. Our original trees got it from red sapsuckers, who eat from bark-drilling in the wild, then bring their beaks to our yard and spread the Vert into the cambium layers in OUR trees. I used to think they were cool birds to watch in our front yard. Now I chase them off!ReplyDelete
I think we should make a VW survivors club! I'm glad to hear you are happy with your replacement trees. It makes complete sense that the sapsuckers could carry the disease as they move around, but how aggravating!!Delete
and just in time to not block the new house next door. i hope i will recognize this disease if it strikes. sorry.ReplyDelete
Willow..clearly the universe does not want me to have privacy. *Big Sigh*Delete
That’s so tough after nurturing your tree for eleven years! I’m sorry, Jenni.ReplyDelete
Thanks Jane! I've had a heavy heart the past few days, especially when I look at that blank spot.Delete
So sorry that you had to cut down this special tree. Could you get a gargantuan pot and plant another just like it atop the spot where that one was or would the fungus find it's way into the pot?ReplyDelete
Hi Peter, that's a very interesting suggestion. As the disease is soil borne, it's quite possible that would work. However, my daughter has lobbied to replace with grass so that she can have the area for practicing cartwheels and other gymnastic moves. I roll my eyes at this but then remember, I'm still in the stage of life where the garden is not all mine to enjoy.Delete
So sorry to hear you had to cut down this beloved tree. I know you really adored that red foliage.ReplyDelete
