Tree bark decay
Our stryax japonicus has splitting and punkie bark at the base with fine powdery material on the ground. The tree is over all healthy looking with nice leaves and flowers, wondering if there's someway to treat this problem? Thanks in advance for any help you can offer!
Tillamook County Oregon japanese snowbell
Thank you for your question about your Japanese snowbell tree. These trees are known for being disease-free, but that doesn't mean they're not responsive to weather effects. There are several reports of these trees beginning to lose bark when they are several decades old. Here is a link to an article about bark peeling generally, whose advice you might be wise to follow. You should also monitor this area closely, as it can be an entry place for both pathogens (fungi and bacteria) and insects. If the split continues to grow, or you see mushrooms growing on the trunk or the base of the tree, you should consult a professional arborist to assess the viability and safety of the tree.
Hope this is helpful. Good luck!
