Two Maple Issues..need advice...
I have a newly transplanted Autumn Blaze Maple in Whitefish, MT (Northwest Part of the State). It is approx 16 feet tall or so. Planted last summer. Was doing very well until I noticed two issues:
1) Small white spots on the bark last fall. Start a few feet above the ground and go up to midway up the trunk. White, dry and powdery. Almost thought they were bird droppings or insect larva or pods, but when I scrub at them, just seem to be white powdery substance. Bought an organic 3 in 1 fungus spray, hasn't seem to do much of anything. The spots don't seem to be doing any damage. Have lasted all winter and are still there, don't seem to have expanded, but it is still early in the spring season.
2) Just this spring, one limb has turned wet and black, and is secreting a sappy / watery liquid. No obvious wound. I have photos that I can send. Only thing I can find online that may be the issue is "slime flux". Looks awful and sap secretion has me worried. The rest of the tree is budding and seems fine...
Thanks in advance!
