Any remedy for a "stressed" maple tree?
I have a nearly 25 year old maple tree that appears to be stressed. For the last two years, in the spring, a large section in the center is late to grow leaves. This section is also the first to change color. It is now in process of doing so. Is there any treatment or cure? Will it get worse? Will it eventually cause the tree to die? See attached photo. This has never been an issue until the past 2 years. I do not believe it is compacted soil, as I use a push mower and there is never any heavy equipment in this area. (Assuming that's how soil gets compacted.) Any advice is appreciated. Secondly, can you identify the plant or tree attached photos. It grew up from the remains of an unidentified tree (a very small sapling) that was cut down last year. If it is a tree, I would like to preserve it. If not, I will remove.
