I've got a crimson maple, about 10 years old. Sometime in early August one branch began to dry up, the leaves did. It has slowly spread to 3 or 4 surrounding branches. The branches themselves are still very flexible, they have not themselves dried up nor do they break off. I cannot figure out what is going on with the tree itself however and was hoping for some ideas. I'll post a photo tonight and get some more up in the morning. For context I live in Eastern Washington State
Here's an day shot, one side of the tree is fine, the other side is drying out. Was wondering if anyone has any idea what it is, thank you.
Thank you, it may be stress, several of the low level branches appear to have those stress marks at the area where the branch extends from the trunk.
I can't see well enough to tell but it looks like the roots of your maple may be girdling (choking) themselves. From the bright green grass, I would assume you have been giving the tree enough water through the dry months but could you have been giving it too much? There are so many possibilities from diseases to growing conditions. Is there an arborist or horticulturist you could hire for a consultation? This website suggests some potential problems for Crimson Maples. https://stonepostgardens.com/crimson-king-maple-tree-problems/#:~:text=Their foliage makes them prone to heat stress,newly planted or thin-barked maples to prevent sunscald
Not that it should necessarily make any difference regarding possible diagnosis, but the afflicted tree is 'Crimson Sentry' rather than 'Crimson King'. There being no cultivar of Norway maple named simply "Crimson". And using "crimson maple" as a common name is undesirable because there is more than one cultivar with crimson in the name. Hence Margot putting up a link to a discussion of 'Crimson King' when the thread topic is an example of 'Crimson Sentry'.
'Crimson Sentry' is a bud sport of 'Crimson King' so I think a list of tree problems affecting CK should be useful to @Aaron74! even though his tree is CS.
