Dragon fruit update 2024.15: Update on the last toothpick grafting.

Update on the toothpick grafting of the hybrids from the back-cross of KXT RR with KVA. Lesson learned: no need for plastic bag protection after grafting; leave the grafted seedlings outside right away is better than "protect" them inside; directly grafting seedlings on branches with a tiny hole better than grafting them on freshly cut surface of the branch.
