I did like Adam suggested and grafted the few remaining seedlings chempadeks I had onto jak fruit root stock, I think im seeing the buds push on a couple of them. I will post picture as soon as I see any real growth.
Any updated on this grafts David, did they took?
I got grafts to take from budwood I got from 1 year old seedlings, but ultimately they still lacked vigour and died. I tried again two months ago with some budwood off the large chempadek in the Whitman pavillion at Fairchild. They took and seem to being doing okay.
Noris told me though that the tree in the Pavilion has never flowered and that even though it was 20 ft tall it was starting to lose vigor and turn yellow and they havent been able to fix it. Maybe there is something is the air. lol
