It's a young tree- it is infested badly with something that is a solid covering, rough in texture, light grey in color and resembles rough cement, and is difficult to scrape off with a finger nail--what is it and how do I get rid of it? and what do I treat it with? Thanks, Gail Wise
Ginkgo Trees are generally resistant to disease and pests.
Weather can effect the barks of the trees and slugs are know to eat the leaves.
Honey Fungus also can be an issue with Ginkgo Trees.
Your description does not suggest any of the above known issues.
Is the issue on the bark or leaves of your tree?
If the leaves are covered, I would take a sample to your local County Extension Office.
They may help in identification. Images can also be taken to the office.

There is a rust colored fungus growing in our ginko tree. What is it and how do I treat it?
Without an image, it is hard to identify.
This could be Cedar Apple Rust.

My Maidenhair tree is looking unwell - leaves are small and dull in colour - we have lived here for ten years a owner before us for 30 years and I would think the tree is probably close to 40 years old. Any suggestions what I may do to restore the health of this tree
Since these trees can well outlive humans, I am likely to say that there is a pH issue in the soil. You can help condition this back by using both dolomitic lime, and iron sulphate. These two should restore your tree to health.

I have a two year old tree. It is spring and no sign of life, how can I tell if it is living?
The first thing would be to bend the tip of a stem. If it is brittle then go down and scratch the stem until there is a sign of life. If the whole tree is brittle, then it has died. If there is a sign of life, then cut back to that point, and it should recover.

My ginkgo is growing straight up, I would like it to branch out a bit and fill out. Is it possible to prune my ginko? Can I cut off the top middle shoot and will it branch out from there?
Generally, you will want to prune at the point that you want it to start branching. This would generally be about 3 to 6 feet tall. So anywhere between here will be fine to cut. Just leave yourself room to work in the tree, as it can get rather bushy the lower that you trim.
Small, newly planted gingko tree - leaves are pale green to yellowing and beginning to drop. It is awful red clay soil so I mixed top soil with the clay & used starter fertilizer at the time the tree was planted (about 6 wks ago). I think it is too early for the fall color change but sure don't know whats going on. I planted a 2nd gingko about 10' away & it seems to be doing fine. We've had regular rainfall & the summer hasn't been too hot so far. I have watered both trees equally when I thought it was needed. I need all the advice/help you can give as this tree is much to expensive to let die! Thanks.
Well draining soil is key to success with this tree.
Amendments for clay soil should include compost.

The ginkgo tree in my yard is abut 40 feet tall and produces a lot of leaves that lay on the lawn until gathered. I wait until most of the succulent leaves fall then I gather them. I noticed the lawn under my tree has died. I can easily roll the sod up with a rake. I suspect the toxicity of the leaves may be killing the lawn. Do you have any information about this?
These leaves don't usually harm lawns unless it is excessively wet during the cold months. This can cause a fungal infection that will kill off the lawn. To be safe, I would rake them up as they fall. I would also recommend adding wettable sulfur around the area to kill off anything that could be infecting the soil.
