Striped Maple problem #755396

Asked June 10, 2021, 5:40 PM EDT

One of my customers Striped Maple tree is having problems, large sections of a substantial limb are discolored, something is happening? The tree is about 20 years old, I put Plant Tone in the garden in the spring and it has never been sprayed with anything, however there is a Walnut tree in the neighbors yard about 60 feet away. They have a sprinkler system, but as of this year it has not been turned on. Can you tell me how I can help this tree? I have more photos, but it would not let me load them, files too big I guess.

Expert Response

Please try to attach more pictures. The maple should be tolerant of the walnut. It prefers acid soil, dappled shade, and moist soil.

Maples are famous for having a girdling root problem, so an arborist can carefully excavate the roots and check for that, correcting any that are found. Search by zip code here- www.treesaregood.org

Your pictures may show more, such as canker or insects. Try saving your pix in a smaller format first, then attach here.

Sorry Debbie, the two you sent were rejected by our system with a “file size too large” message. Please save the pictures at a “medium” or “small” size ( 1mb or less should work) and try attaching them again. Thank you

Hello Debbie,

The new pictures do not add much more information. Unfortunately, root problems can lead to unexplained death of leaves and branches in the canopy.  To repeat what Laura said, a certified arborist can help you, by exposing the roots, to see what is going on underground.  Find an arborist in your area at www.treesaregood.org to find one in your area.

Thank you for contacting Ask Extension.
