Thank you speedster for the info. My grandparents had a small orchard about 1 acre. It wasn't anything fancy but I loved that place as a kid. After they were too old to tend the trees and farm the hillside just went wild with peach trees everywhere. lol The trees do produce peaches but are only golf ball size and not very good. The trees range in size from large trees to seedlings. My intention is to dig some of them up and move them to a different location. Use them as rootstock for red haven, contender and other good verities. I just didn't want to wast my time if they would not be as productive and vigorous. In my area I have read that lovell rootstock is good for peach trees. would their be much if any benefit to grafting my trees onto lovell verses using the rootstock I already have? I hope to eventually have about a 5 acre orchard.

Would their be much if any benefit to grafting my peach trees onto lovell rootstock verses using the rootstock I already have?

Not really, your established trees will grow better in the short term. Long term it's close to a wash.

Thanks pip313, So for the long term I would be better off going with lovell?

I'd only go guardian if I wanted to go through the work and time of rootstock.

id really just use what you have. You have far too many trees to disregard them.

reason is best resistance to most issues peaches face. But what usda zone are you?

zone 7b. Where can guardian rootstock be purchased? I'm probably just over thinking it. I would rather use the rootstock I already have if it doesn't make a big difference in the long run.

I'd spend the money on scion myself. No need to waste any on roots.

Thanks pip313, That's what I was thinking. Just wanted to make sure first. Thank you very much for taking the time to help me out.
