Growing peach, in general, is not a piece of cake. You may need to spray for diseases and insects. If you read up old threads, you will have some ideas what could happen. Then, you can decide if you want to return the tree.

what type of fertilizer should one use? I did see one very small peach but its gone I don't see it any-more don't know what could've happened to it How long could I keep it in the container since I don't have any room for it in ground

Organic fertilizer or a water soluable type like Miracle Grow. I've grown trees like that in pots for 4-5 yrs. Then it needs repotting because it will become root bound.

or root pruning? instead of re-potting? did your trees in containers bear lots of fruit ? do you have any pictures?

Hey man I like to help but how about "thanks for your input" before you rapid fire four more questions?

A little common courtesy goes a long ways.

I already did thank you look at the first post "thanked by Kings_rose" 1 hour ago

So he did. I hadn't noticed that feature of Houzz before.
