I have a flowering peach tree that has the dark leaves. On some of the leaves though, they look as if they have blisters (yellow like). They start small and spread till they cover almost the whole leaf. What is the problem and what is the solution?
It sounds like the onset of peach leaf curl. This article will help: https://www.gardeningknowhow.com/edible/fruits/peach/peach-leaf-curl.htm
Peach tree leaves have bumps and curl up and fall off tree.

My trees have a fungus. What do I need to spray or dust with? I think it is a blight.
You can use copper sulfide or neem oil. I personally like neem oil, as it is also a pesticide but does not hurt bees. Here is more information on it: https://www.gardeningknowhow.com/problems/pests/neem-oil-uses.htm
Is there anything one can do for peach fruit that is still on the tree in order to make the fruit sweeter tasting? In other words, is the taste of the fruit already fixed by the time the fruit has appeared, or are there methods to enhance or produce better tasting fruit as the fruit grows? I know that if you over water, the fruit can be mealy and tasteless, but does fertilizing control the sugar content at this stage?
Of course, having sweet fruit begins with nurturing the healthiest possible trees. This article starts you off in that direction: https://www.gardeningknowhow.com/edible/fruits/peach/peach-tree-care.htm
I planted two Elberta peaches and Green Gauge plums in the spring. We have sandy soil, so I dug deep large holes and filled with Earthgro topsoil. Then put a PVC pipe in the ground to get the water down deep. I may have overwatered at first, have stopped watering since. The top 4 inches have dried out, but still have burned tops and losing leaves, which are folding and puckered. Is it the Earthgro topsoil? When should I water again?
You probably did not overwater them. They are likely suffering from transplant shock. Increase water and give the trees some phosphorous rich fertilizer to help with new root growth. Really, unless they are in standing water, you cannot over a tree in the first year.
My peaches start to grow then stop and remain as hard as a rock until they fall off. Any help?
This is a pollination problem. The peaches cannot reach full maturity if they are not pollinated. They grow a little but then the tree aborts them. Here are some articles that may help: https://www.gardeningknowhow.com/garden-how-to/beneficial/insect-pollination-process.htm, https://www.gardeningknowhow.com/garden-how-to/beneficial/creating-a-pollinator-garden.htm
Peach tree is 3 years old. We have only gotten 1 good size peach. The tree is full of peaches but they are not growing. They are size of a baby fist. Why are they not growing?
A few things could cause this. First, it could be a chilling issue. If a peach tree gets just a little bit too little chilling in the winter, it will button the fruit, which means that it tries to grow them, but they will be deformed, stunted or fail to mature. Since no one really had a cold winter this year, it is likely that chilling could be a factor. Here is more info: https://www.gardeningknowhow.com/edible/fruits/peach/peach-chill-hours.htm Another possibility is that there is a problem with pollination. If this is the case though, the tree will drop the fruit in late spring or early summer.

If your tree is at least 3 years old and it carries the small, immature fruit throughout the season, that may be your problem.
