The peaches on my peach tree have a white jelly like substance oozing out of the peaches. The peaches are also rotting on the tree. The peaches don’t appear to be getting any larger. Should I prune it back? What sort of chemicals should I spray on the tree? I spray them every 2 to 3 weeks with fruit tree spray.
I cut the branches where it was some white jelly and remove some of the peaches. Did the rain have something to do with this, because we had a lot of rain?
It sounds like you may have peach borers. This article will explain more about them: https://www.gardeningknowhow.com/edible/fruits/peach/peach-tree-borer.htm
My peaches are small (size of a tennis balls), hard, and oozing a clear, sticky liquid. The leaves are sparse and thin (like paper). I don't know if they are salvageable or even if the tree is. What can be done, what is the cause?
There are several insects that can cause deformed and oozing fruit. This article has information: http://www.clemson.edu/extension/county/laurens/mg/askmg/076_peach_tree_worms.pdf
Also there are fungal diseases that might cause this. To correctly diagnose the problem, take some fruit samples to the Extension Service. This link will help you locate the nearest one: https://www.gardeningknowhow.com/extension-search/
I purchased a tree and on the trip home all of the leaves turned brown. Watered and fertilized leaves did not come back. Trying to decide if it should be trashed or not, but have found leaves growing just above the soil on the trunk. Any thoughts or suggestions?
Your tree should not have died on the way home, unless you drove through a deep freeze or car wash, or some such thing. Or you left it sitting in the vehicle after you got home for several days so that it dried out. However it happened, the dead leaves are gone. If the branches are still bendy and green, it might make new leaves. If they are crispy and snap when you bend them, they're all dead. The green leaves around the bottom are leaves from the root stock. Fruit trees are typically grafted, that is a tasty fruit variety of plant is grafted onto a root stock of a tougher but less tasty variety of the same specie. Growth from the root stock is pruned off so the tasty fruit gets all the energy -- unless the tasty tree is dead. If you know you didn't do anything to kill the tree, you might try returning it to the store.

Brown spots turn to moldy mildew then fall off. What can I use that won't affect the fruit? Or is is too late?
Sounds like brown rot, a very common infection. Learn what you need here: https://www.gardeningknowhow.com/edible/fruits/peach/brown-rot-fungus.htm
We bought a house two years ago and the only tree in the backyard we believe to be a peach tree. However, each summer it only produces green balls that never ripen to look like peaches. Any way to encourage the peaches to ripen?
One question -- are the balls still hard when they fall off the tree? Here's an article that tells you more about the possible causes of peaches falling off before they ripen: https://www.gardeningknowhow.com/edible/fruits/peach/peach-tree-fruit-drop.htm
Rotten peaches, mold and mildew - is it ok to treat peach tree while there is fruit on it?
The application of Green Cure fungicide is earth friendly and about as safe a treatment as you can get. Here is a link to their website, check it out: http://www.greencure.net/
I have used this product on my rosebushes and on my cucumber and pumpkin crops successfully for several years. If you have another product of choice you wish to use, read the label on the product well to see what it says about spraying while still bearing fruit, or call their 800 line if the label information is not clear.
I have two different peach trees in my yard. Last fall we trimmed them. One has a lot of leaves but no peaches, and on the other one the leaves are few and far between. We had a very harsh winter in Chicago. Could that have something to do with it? Both trees are in full sunlight all day.
Yes, the hard winter has affected trees and plants around the country. Another cause might be age -- peach trees need a few years to really get going. Here are a couple of articles that may suggest avenues of investigation you can use to understand the problems: https://www.gardeningknowhow.com/edible/fruits/peach/peach-tree-not-leafing-out.htm
