I just update my web page on the subject:
September 7, 2020: I have not been keeping up on Catalina. The tree at home and the top worked tree in the grove both lost to the hurricane Irma in 2017. The only survivor is the Catalina on Catalina shown in the picture of September 2015. A small tree that was planted between two vigorous trees, as result growing very slowly. Finally this year set 10 fruits. To my amazement I find that the fruit taste very different from the tree at home, actually better. The tree at home produced a very oily fruit with a canistel like taste that I really did not preferred. The fruit from the grove, is much better, creamy, lighter in a way. I measure my preference to where I go to get fruit to eat at home. Every day I'm, going by this tree to take one fruit for home. eat 1/2 with the meal and save the other 1/2 for avocado toast in the morning. Even the shape of the fruit is different. Is less round, bigger seed. That has always been my theory, the terroir imparts a lot of the fruit taste and character. My home is probably the only house in Dade County that is not on rock. I have clay soil, heavily compacted and deep. Last time we dug at 15 feet we still had clay. Probably I'm on an ancient waterhole.
The tree at home was probably grafted on a Waldin seedling and this one on a Catalina. That's another story for another time.
