Minature Peach trees- the leaves are turning pale green- why??

Hello Jan7425, When leaves start to turn color, it's a sign that it is not getting enough water. Try watering it more than usual and it might come back for you. Hope this helps you. Good luck.

are you fertilizing or maybe watering incorrectly. Sometimes either too much or too little water can be the culprit

Check for any sign of a insect infestation.Webbing,holes in the leaves,etc. Spray the tree and soil down with horticultural oil. Repeat as necessary.

Also, if they are in pots leaves will start turning if they need to be transplanted into bigger pots with fresh dirt.

Try an iron treatment that you can pick up at any nursery.

Thanks to every one who answered. I have listened and am trying them all.
