>>1349249Interesting, I'll bear that in mind in future. These grafts are on the north side of the stem and inside a semi-opaque spiral guard so hopefully will be OK. Went back yesterday and the callus is healing up really nicely.
>>1350253I topped one as an experiment to see if it would cause the buds to grow out a little this season. Going to go tomorrow and put some NPK on as an additional push.
Cleft graft has never worked for me, whip-and-tongue and rind are my usual choice.
