Hi Simon, thanks for the reply.
I probably wouldn't graft until later in the summer next year after expected blooms for the scions. I may experiment with a few earlier but you're right, the scion may try to bloom and i'd remove the fruit to prevent death of scion. I have been giving them liquid fish fert now to help with vegetative push now so i'd prob continue that next year as well.
The corriente will definitely be placed in ground. I'll also plant a few manila seedlings, i have a 15g that is ready to go in. I grew out seeds of LZ, cotton candy, sweet tart, orange sherbet, and a few others. They are currently in 1g containers, some more vigorous than others.
I haven't tried bud grafting, still trying to perfect/feel comfortable with cleft grafts. Currently i have about 7 grafted trees on 5g manila that i grafted: maha, coco cream, sunrise, p-22, glenn, and a couple of others. Maybe i'll try bud grafting one of these days.
Have you had experience placing a big tree like this in ground? any tips?
