Well you can't prune out all the older wood. If you did you'd be pruning back to the trunk every other year. Whack it back to the trunk, grow new wood the first summer, have fruit the second summer, and cut back to the trunk again. No fruit one year and a good crop the next. So you can't cut out all the old wood every year.

It is true that fruit is born on last years wood. But some of that is small wood lower in the tree very close to old wood, almost like apple and sweet cherry spurs. Often the best fruit is in the upper part of the tree on the strongest growth from last year. So you prune to take out weak, pendant, old, crossing, and out of place wood.

If you cut out 20-30% of the wood each year there will be plenty of vigorous growth each year that will produce good fruit the next year.

On peaches the lower fruit on pendant wood produces poor fruit for me. Whereas my nectarines produce great fruit on that low weak wood down under the tree. Maybe it's the reflective fabric under the trees that reflects light back into the bottom of the tree. Also I find nectarines so much better than peaches that I only grow two varieties of peach anymore.

Fruitnut- don't get humid climate growers too hyped up about nectarines- they are much harder then peaches and even though I'm willing to do the fungicide applications I still love my less fussy peaches.

Books are always wrong about pruning. They are also always right. Some apples bear best fruit on vigorous previous years wood some, like Macoun, can be pruned almost like peaches, but on a 2-year cycle. All apples produce best fruit from relatively young wood.

I think Fruitnut is dead on about fruit placement on peaches although I haven't shared his experience with nectarines, maybe he's right about the fabric.

Young peach trees should grow quite vigorously and when they do some annual wood is too big to be useful so some shoots of the largest diameter are removed completely. The bearing wood left should be far enough apart to allow peaches to ripen without touching peaches on other shoots.

Why are we talking about pruning peaches now? I suggest you wait until trees are in bloom and it will be easier to understand what needs to be done then.

I have three peach trees.Every year when all the leaves drop off,I cut every thing off above eight feet.It's true that the fruit grows on last years growth, but I also find that a lot of the fruit also grows on the growth from the year before that.The small branches that are not going to bear fruit will dry up in time.Thats when you can prune those off.By the way I do the same with my apricot trees.
Good Luck

thanks...I will post pics of my pruning

Pedroza, I think you're mistaken. Peaches don't even have leaf buds on 2-year wood. There are small one year shoots connected to the older wood that are bearing your peaches. I'd bet the farm on it.
