This is going to be my first year attempting to graft stone fruit, persimmons, and pecans. When is the optimal time of year to graft these type of trees? Can a freeze/frost kill a fresh scion if grafted too early in the season? Im in Zone 7a
Also have scions waiting in the fridge for the past few weeks. Is there a certain shelf life on these things?
I usually harvest scions at this time and store them in the fridge in a plastic bag, with the cut end wrapped with a moist tollew.
From the tree species u are working with ,i have grafted only peach and a close relative ,almond. I waited till i saw the leaves just emerging and grafted at that time. I did 4 clefts and 3 bark grafts on the peach, all were succesfull. The almong got around 8 clefts, all were also succesful. Infact the procedure with the almond is similar to what u want to do, i worked two main branches , they were slow to take but then by the end of summer had around a meter of growth. Also i am starting to wrap every graft which i do with a white band, to keep them cooler in the hotter days of spring. .
