I did both cleft and tongue (1 on the peach tree branch, 3 on the root stocks). After this, I think tongue graft is easier and secure. However, still uncertain because these 4 SpiceZ nectaplum scions have mostly flower buds.
Bark graft is not applicable here. I had 100% success with cleft graft (10 out of 10 atemoya onto cherimola). Bark graft about 50% (guava) initially, however end up failed because the grafted branch couldn't support the big trunk/root.
about cleft i find that it helps to make the cuts very long, that way it has more space of contact with the rootsock. And there is the problem , u cant make the cut with one move due to the length of it, so i usually end up with something not as smooth ...
its pretty hard to screw up peach or nectarine grafts. even the sloppiest of grafts take easily. Very rewarding trees to do grafting on.
Spicy Z has russeting (skin) issues in my yard. I top worked mine to peach. Every nectarine I grew had the russeting. Ive gotten rid of all of them in favor of peach which all look pristine.
i did about 20 nectarine grafts onto wild plum rootstock , too early for conclusions about any of my grafts. .
Cant this russeting problem be solved with spraying against trips ? I am doing the oposite ,i removed my old peach since i planted a nectarine last year. I don like the fuzz on the peaches, thats my problem with them, probably the fuzz protects the fruit from the trips ??
