I have a small orchard based loosely on The Permaculture Orchard DVD (1/4 acre). I bought a grafting tool that cuts the notches for me rather than rely on my knife skills (which failed me on my last attempts). I'm in Central Illinois, zone 5. I'm just wondering when I should cut my scions, when should I attempt to graft the scions onto my selected trees? My scions will be from the younger trees I've been planting (in the ground 5 years or less), and I am hoping to graft them to my 40 year old (at least) apple trees and pear trees, and also onto some 8-10 year old volunteer peach trees. So, scions and 'rootstock' are in the same place. Can I just wait til spring and cut scions and graft them right away, or should I cut the scions and get them prepped to rest dormant in the refrigerator until spring. Is spring even the right time? Again, I'm wanting to graft apples, peaches, plums, pears, and nectarines. Also, I have 2 apricot trees (in the ground 8 years, 1 Manchurian apricot and 1 dwarf moorpark apricot) that have never fruited and was curious about grafting peaches, plums, and nectarines to the apricot trees. I like to read, ( I've read almost every thread in growies and critters) so don't be scared to give me as much minute detail as possible, anything I need to know. Thanks a million!
