Southwest Idaho region: alkali content is a little high here, also clay below surface 1 foot to about 18" to 2 foot. I prepared the soil with garden mulch certified weed free and then planted the tree to the root ball as recommended by the vendor. The water ring is 30" in diameter and about 4" in depth and I water it about every 2 days. It is about 7 feet tall with a good established root system. I have used Miracle Grow on it and done this mixture 1 time so far last night because my tree leaves are starting to curl and turn yellow. It has also been sprayed with malathion.
I suspect that your peach tree has peach tree leaf curl, which is a common affliction of peach trees. Given that peach tree leaf curl is a fungal disease, an insecticide spray such as malathion would not be effective.

My peaches are being chewed up by some insect. I have covered the dwarf tree with a bird netting so it is not birds. What kind of bug is eating the peaches? And what can I do to prevent this?
Without a photograph or other details, this is hard to say, but here is an article that discusses several possibilities - hopefully you will find a match!

When planting a peach seed, do you plant it with the pointy end down or the rounded end down? I want to plant a peach seed.

Basically, it doesn't matter how you lay the peach seed - the sprout will make its way to the surface no matter what. I would recommend just putting it rounded side up.
Growths appear on the twigs of our peach tree, They are white and seem to have come through the bark. They seem to be mostly at 'junctions' and are a bit like sticky candy floss if you pull them off. They don't seem to grow much, to about half a centimetre max, and oval in shape with the dark bark they have pushed through still on one end of the white stuff. I can't find a picture on any website and therefore don't know what it is, or what to spray with. Can you advise please? Many thanks - Richard Gordon

In your article about peach germination, you say to place in plastic bag with soil and refrigerate. Do I seal the bag?
I would say keep it mostly sealed but leave a one inch opening.

The leaves on my Redskin peach are wilting, turning yellow and falling off. The fruit that was growing is wilting. We had a lot rain in central TX. How can I save this tree?
Rain is needed, but to much can kill plants and trees.
Your tree is suffering but may recover.
You will need to watch for signs of bacterial and fungal diseases that may appear.
Here are links to help you.
Best of luck.

I have a Georgia peach tree that is a little over 2 years old. It has started to produce peaches. The problem is that the branches aren't thick and strong enough to hold the weight of the peaches. One branch broke with a bunch of peaches on it. Is there any way to save the branch and keep the peaches on the branch?
It likely needs thinning, especially since your tree is still relatively young. Here is more information: https://www.gardeningknowhow.com/edible/fruits/peach/peach-tree-thinning.htm
