there are many questions like this in the fruit forum ...

and those peeps are a closed group who do.. frankly.. weird things to fruit trees.. lol .. [what i mean.. is that i never see these experts in this or the tree forum]

you might want to ask this there...

i am going to bet.. the understock MIGHT be an issue .. but i am a tree guy.. not a fruit nut ... and i doubt you will be able to ID the understock ...

most of the peeps there.. mail order very specific cultivars.. just to avoid the issues you are having problems with ...

if you were to mail order GOOD STOCK.. you might have peaches in 2 or 3 years ... if you mess with grafting.. you might extend that 5 years.. only to find out.. you have rootstock issues ...

which is why i might suggest.. you suck it up.. and start over with some new trees .. and dont get me wrong ... play with these if you have the room.. but get some good ones.. so you can enjoy some fruit in this decade ...

You have available in your county a university extension service, at least partly paid for with your taxes. Look in your phone book under county offices. They know what your growing conditions are and are eager to help you. Al

Thanks KEN and Calistoga

To start my county agents office is less than 1 mile from my house.Have been several times for different problems no help.After seeing what was said I think i am going to buy some new trees.Leave old trees get new trees to growing then try grafting.I apreshate the info.
