Hi, and thanks to both for your advice/confirmations. One thing that does make me nervous is that I am 2 blocks from the Gulf of Mexico here on a barrier island, and usually two times or so each summer, there is flooding during storms. I will be putting the Oro Negro in a raised bed, though the future does not bode well for living at sea level in Florida (not to get political).
One other concern. We planted a 15gal Day variety about 4 years ago. By the second year we had it it set fruit for the first time, and I am embarrassed to admit we were not aware that first-year avocado fruit should be pulled off so as not to inhibit growth of the young tree. There was an enormous yield (and very good flavor, I might add). The next year--last year--produced maybe 4 avocados. This year there was what appeared to be a large amount of avocados budding, but none did. Quite a bit of leaf/branch growth, but no avocados. Is this anything to be worried about, or will the tree be producing avocados in another year or two?
