It is actually micro-chip budding where smaller buds are used instead of the regular size for t-budding. This produces faster growing trees and fast enough to replace trees that are damaged by greening diseases.
I have actually been successful with microchip budding as a trial, only when the scionwood available were super-tiny. I did multi-grafts so didn’t keep track of single grafts this way on single rootstocks. I will surely try this again!
I want to make my Meyer lemon more bushy for indoor growing. Do you think I can use this technique to graft buds lower on the tree? It’s only 1-2 years old.
