I currently have 7 small grafts growing - 5 cleft and 2 t-bud. The t-bud are proving to be extremely vigorous, whereas the clefts are growing much slower. Is this due to nutrients reaching the bud much quicker than traveling the length of the scion on a cleft? Sloppy graft unions on the clefts? (I’m still very much a novice). I’ve had a higher success rate with clefts, but may switch to t-buds only.
Note: all are on the same rootstock and in the same soil mix.
I find that clefts take a little time to get going....but as soon as the healing is done they become vigorous growers. A budded rootstock takes off vertically and reaches for the sky. It seems to outperform clefts. Like all else it depends on the health, care, type, and enviroment of scion and rootstock.
