Not a lot to work with here. Its not the soil. What is your watering schedule? One thing that happens frequently is tree drowning. So you dig a hole and put the tree in it. then you put the soil back, plus maybe some compost. If the tree was potted you have that soft potting soil. So when you water, the hole take in the water very easily, but the surrounding soil, and soil under your hole do not. Therefore water sits in the hole conttaining your tree like a bow,l making your softer soil a big glob of mud which smothers the roots.

If it is this, clear any mulch from around the tree so the sun can help try to dry it out, it's race to get it drier before the tree dies. I predict you will loose that race (if it's the problem) So if you bought it at a local nursury they probably have a replacement guarantee. don't wait to long to give in and use that. The longer you take to get the new tree in the ground, the more it will be stressed by heat.

Thank you for your thoughts. I added a picture to the original post and another one here if that might help a bit. (not sure how to add more than one picture per post)

transplant shock .. water properly ...

IMHO.. disease simply doenst not work that fast ...

the experts.. would have planted a dormant.. leafless tree ... sometime in april or so .... to avoid the shock to the leaves ...

the true tree peeps would have suggested not to amend a planting hole.. and to plant high in regard to BAD clay ... does your clay PERK???? ... drainage is very important to trees ... and if you palnt a tree in a clay cauldron.. that does not drain then problems can happen ... adding a high water retention soil to this type of hole.. might only make it worse ...

with the transplant .... you interrupted the root mass's ability to support the leaves on the plant ... ergo.. some of them are being sacrificed for the greater whole... not a big deal .. unless they all fall off ... and even then... if properly watered ... and you dont kill the root mass... most trees can releaf ... not the best thing to happen ... but not the end of the road ...

i will go back to the tree forum now... lol

Don't worry about those yellow leaves on that tree Peach do same every year. The older are larger leaves one to watch for problems yours look great.

Thanks for the insight.

Nope, I am definitely not an expert. This is my first fruit tree ever. My kids and husband got this tree for me for Mother's Day so although I guess it should have been planted earlier...it was planted when I got it.

We added to the soil because my husband had to dig up a bunch of weeds and grass in the bed where we were planting this trees and some other bushes.

It has actually been a pretty decent Spring here. No crazy torrential downpours but some nice steady rains spaced out. My husband watered a couple times in between but not very heavily.

There is no mulch around the tree.

I am not sure if the clay perks and not sure how to test that. I could probably make some pottery from the soil though. :)
We just moved here a year ago so growing things in this soil is different for me. We didn't have as much clay up north as we do here.

Thanks again.

is the tree doing o now?

Kestrel...drainage is of paramount importance as everyone here has mentioned.
I don't think that is your problem, in fact, I don't even think you have a problem. My Hale Haven does this every single year since it was planted, and it most certainly does not have any drainage issue whatsoever as there is almost zero clay content here and the tree has awesome drainage. I don't see any indication of any common peach tree issues either. You just planted it, so give it an opportunity to acclimate itself.
In the future however be mindful of what these folks have said regarding the bathtub effect of adding compost/potting soil to plantings in heavy clay though.
The best peach I've ever eaten was a Red Haven, and is/was the most widely planted peach in the USA. There is a reason for that.
It is however susceptible to bacterial spot, something that runs rampant in our zone. Really though, peaches in general offer little in the way of disease resistance anyway, so I think your family made a good choice and with a little luck will be a nice tree for you.
