Dear Appledaughter - I have a couple of those myself... I've often wondered who'll end up caring for their Daddy's menagerie of fruiting trees and vines
? I live just SW of Gaston and would be happy to look over the orchard. If your father was a member of HOS, I may have known him.
"Does anyone know of a trustworthy and reasonable priced pruning resource? Any recommended companies or folks?"
... yah ... Let me ask our Webmaster, Steven if he will pass my contact info to you?
I only have an 'opinion' on whether copper sulfate and lime sulfur are considered "Organic?" Both of those have been the extent of my own dormant spraying, and I've always 'considered' them Organic... But I'm not up on the current State Standards regarding Certified Organic?
If you would like to contact me regarding all your questions, please do. I'm also happy to consider the pruning work. With regard to my 'credentials' - please read my posts, or contact Karen Tilou (HOS Arboretum Manager), I'm reluctant to give anyone's phone or e-mail online (hers is in our Pome News - back page), but ask her how I did last Spring? Karen's a master pruner & grafter as well, she may also have some contacts...
