(couldn’t find a topic covering this exact topic)
I have a hand full of apple trees I’ve started from seed this year, sourced from 60+ year old heirloom
apple varieties located on the farm I grew up on.
If I wanted to perform whip and tongue grafting onto these root stocks, how old would you recommend the root stock be? First time grafting onto self-grown root stock and don’t want to do it so soon that it stresses and kills the plant.
Age is probably less important than the caliper of the tree,I would consider anything over 3/16 fair game
As stated, diameter is more important than most other considerations. The rootstock should be either dormant or recently broke buds with growth less than 6 inches and the scionwood should be dormant with unopened buds.
I prefer to graft on rootstock between 1/4 and 1/2 inch diameter. 5/16 is just about perfect because apple and pear scions can be chosen in that size range.
Thanks guys, I appreciate the advice!
