Thanks for the excellent information folks.
Dennis, when letting the trees callus I assume it’s ok to keep them damp but unplanted? Since my materials are coming in mid March, I’ll get them grafted and let them callus up in a cool dark room for about three weeks. Should I then move them into a cold area 35°- 45° F until they are ready to go outside in late may?
Is coconut coir a suitable medium to keep them moist in?
Thanks!
