Maple tree with possible fungus


So I bought a house and it has a red maple in the front yard. It seems like the previous owner moved a long time ago and after this period and neglect of the yard and trees, our maple seems to be half dead.

I have worked now for about 2 years trying to get this maple to come back. I noticed that the root flare was covered with grass so I gently exploded that back to the air. I also tried watering it more frequently. However at the end of last year I began to notice that the bark started to fall off. Under the bark was a black substance.

I dont know enough about trees to say if it is the tree healing or the tree dying.

My question, is this maple have a fungus? If it does can I do anything?

If I cut out the dead part of this tree can it come back? Or should I call it and cut the whole thing down?

Premature heavy yellowing leaves on Honey Locust tree.

I am working with neighbor who has a mature 40' honey locust trees that over the last month is dropping a lot of it's leaves and showing heavy amount of yellow leaves on edge of the branches. We are also seeing yellowing grass underneath the canopy of the tree. The rest of lawn is fine. She did apply a broad leaf fertilizer a month ago that includes herbicide for billbugs. The temperature on the day of fertilizer was about 86'. Not for sure what time of day it was applied. Also we had a very wet late winter & spring about 250% of normal. I'm included a few photos of tree backed off and up close of yellowing leaves. Also photo of yellowing lawn underneath. Anyway, any input would be great. Thanks again for your help.. Don

Grow Cherry Laurels in Boise/Meridian area?

We would like to put in an evergreen hedge, but don't want arborvitae. Would cherry laurels (or English laurels) do well in the Meridian area? It would be about 12-15 feet from a smaller irrigation ditch, in full sun. What soil prep is required? Do they require much maintenance to have a somewhat natural-looking (not too manicured-looking) hedge? Is there anything else we should take into consideration?
