steere:

Could you tell us what kind of fruit trees you have? It is common for a few leaves on the lower branches of trees like peaches to turn yellow and eventually fall off. This is nothing to be concerned about. Concern is when they all turn yellow and fall off.

If your trees are growing vigorously, I would hold the fertilizer. Most fruit trees do not need it in ordinary soil, although mulch around the base can be helpful to slowly feed the trees while helping to retain moisture.

Sounds like you have a perfectly normal situation. But if you have peaches, and they are growing fast, don't let them get too big and bushy next season before you start to think about keeping the centers open and pruning them for shape.

Thanks jellyman

I have cherries, apples, peaches, necterines, apricots, asian pears, european pears and plums.

They all have grown very good this year. Between 2 to 4 feet. They are all mulched and i have started to train them to allow air circulation.

open center for peaches and necterines and espalier for apples and pears.

They are in good soil and get a fair amout of sun.

Glad to hear about some leafs turning yellow is normal.

Thanks once again!
