Mark, I see the tree in the video, it is bushy as my grafted branch was. Sometimes its hard to see how the actual branch wood is growing (straight or droopy) unless you look inside the canopy/leaves (yes, hers is straight and nice looking). But I must admit my Holiday was grafted on the lowest branch on the tall seedling plant which is about 15 ft. So it may have been more in the shade of my other varieties that are grafted. I tried to tie the branches up to the higher branches of the tree but new branches would still look like the photo of Brad's tree (wants to point downwards). When the big avocado fruit starts to grown the branch droops even more.
I don't give any fertilizer to my trees, just good old water and they grow rather fast, the Holiday graft started fruiting by the 2nd year. My Hawaiian seedling rootstock grows about 8ft+ yearly so I need to cut it back every year. Any grafts I put on this tree grows fast and fruits rather quickly. Maybe the Holiday would have grown straighter if it was on its own rootstock and not grafted on a small side branch on the lowest part of this tree I have. I do like the taste of the fruit.
