I’m going to start harvesting from my Hass tree soon so I thought I’d show yield results from the girdles I did on it in the fall of 2022 and the flowers that are emerging from the girdles I did in the fall of 2023. On those recent girdles, I used narrower...

Thille is the low-pro link between numerous famous avocado varieties. Even though Thille trees barely exist anymore, and not many were grown in the first place, it is the daughter of Hass, the mother of Gwen, and the grandmother of Lamb, GEM, and the new Luna. So the...

If avocados have a royal family, this is it: Hass and its heirs. Take a look at the family’s most prominent members, as well as some lesser known relatives. Where and when were they born? Who first grew them? Is there a next generation on the way? I hope you...
