I finally discovered what the heavy black stuff on my deck and concrete drive is. It's sooty mold. All I have around is 100 year old, maple, oak and pine trees. How do I get rid of the aphids (if that's the problem) from such large plants? It took me 5 hours of constant high pressure cleaning to get most of the black off my 8 X 20' deck. A large driveway is still covered and there is a lot of sticky stuff on my car and husband's. Smaller plants such as hostas have quite a bit also. Who do I call to clean the trees off?
Neem oil can be used to get rid of the pests as well as the fungus This article will help: https://www.gardeningknowhow.com/plant-problems/disease/how-to-get-rid-of-sooty-mold.htm

An arborist can help, especially if pruning becomes necessary, but you should be able to mix the neem oil in a sprayer to treat the trees.
My old Maple tree is losing its bark! I have noticed this happening in the last few years. The tree is quite old--we have lived here for 35 years. The branches are full of leaves, they were green in the spring and summer have turned to yellow and orange with the fall. I am very frightened for this tree. Is there anything I can do? Should I be concerned?
Some varieties of maple do have "peeling" barks and are grown for this feature. It is a feature that often takes years to develop, which would explain the recent development in past years. As long as it looks healthy and you do not see any signs of fungus or mold (it will look like a powdery substance) you should not have to worry about the tree.
I have a mature maple tree in my yard that began to show fan shaped fungal growths at the base of its trunk and some of its exposed roots. Is this something that I can treat or will it be necessary to remove the tree?
You would probably need to use a fungicide. I suggest you consider taking samples to your local agricultural extension office for identification and recommendations for treatment.
Best way to plant and care for it. I live on the Gulf Coast.

One of my trees has really bad canker and I was wondering if there is anything you can do to save the tree?

They are sticking to my furniture and cars. Also, should I try planting impatiens this spring as all died last year due to, I'm told, a fungus. Thanks for any help.
The following article is about downy mildew, a new fungus for regular and double impatiens that is deadly: http://msue.anr.msu.edu/news/impatiens_downy_mildew_a_curse_and_opportunity_for_your_garden
As far as the dropping from your maple, it's most likely from an insect or larvae eating the leaves. You would need to identify and tr3eat. It could be pieces of the spent bloom, just guessing.
I have a mature, large green, lace leaf maple that has branches that completely die during the spring and summer. First the leaves become brown and then an entire branch will die. I have been told to use a fungicide by a salesperson at McClendon's, but then was told by WA tree service that these trees usually do not get fungus and that spraying with a fungicide may do more harm than good. Help! What should I do?
Consider taking an example of what you describe to your local agricultural extension service for identification and recommendations. Most salespeople in "box stores", are trying to sell product, and in our area, tree services know how to cut or prune trees.
