N.B.
1/ For mango and sapodilla, terminal scions preferred for W, W & T, We and side veneer.

2/ W=Whip graft, W & T = whip & Tongue, We = wedge, N/N = not necessary.

3/ * Preferred graft methods at top of each list.

4/ Bottom heat preferred for all cuttings and best results during winter.

5/ Some nurserymen prefer leaving 6 to 8 terminal leaves (cut in half) on the scion when grafting. There is definite benefit from this.

6/ +? denotes not essential if use low hanging (drooping down) branches for scions.

7/ Approach grafting not listed - but can use for any species with good success.

8/ + defoliate - but prefer to leave 6 to 8 terminal leaves intact.
