Maple trees dying

Asked July 26, 2017, 1:20 PM EDT

Hello
I have 3 Sugar Maple trees dying and 2 died this spring, Spring die off trees started to leaf out but did not make it all the way, 3 that look like they are dying have very thin foliage, leaves are light green many with brown edges. Can I save these 3 trees, can I prevent what ever it is from spreading to my other maples. Thank you Jim

Hello,

Without seeing the internal staining inside the twigs and branches, this does look like verticillium wilt. ( links below discuss this in more detail) This disease must be confirmed by a lab test.

Several issues like flooding, drought, boring insects, verticillium wilt are possible causes of maple dieback. Since you have multiple trees involved I recommend having a professional, on site diagnosis. Sooner is better than later, as it is difficult to diagnose a completely dead tree, and if it is a treatable condition more trees can be saved.

Call a couple certified arborists in your zip code area for estimates of an on site diagnosis, lab sampling if needed, and complete tree care plan. Have all your trees examined. A certified arborist is not just a tree trimming service- he/she is a person who has been educated in diseases, pests and abiotic issues. Find arborists in your phone directory or here---

If hiring an arborist is not possible, you may submit samples to MSU Diagnostic lab for a small fee- usually about $20 per tree. I would call the lab and ask them what they need to confirm possible verticillium wilt disease. Their submission form, fee schedule and instructions on submitting samples are here---

Here are articles on wilt, its controls, and other common causes of dieback in maples---
