Well, here is one of my first first t-budding attempts done in early/mid May. A Tarocco blood orange.

Looks like you did a good job!

The first successful graft or budding is the hardest, after that your abilities rapidly approve. A nice looking T-bud. - Millet (573-)

I wanted to cut the trunk almost flush with the bud, but I was afraid I would damage the budded tissue so the old trunk is a little extended on the trees I did.

I also did a Gold Nugget and two Seville sour oranges.
