Some times I may have given mixed signal about Oro Negro Avocado. Yes it is true.
In my grove Oro Negro has about the same maturity period as a Monroe. The issue becomes: If I were a homeowner with limited space which of the two I would grow?
Oro Negro VS Monroe:
1. The production is not even ½ of Monroe
2. I think is a bit more susceptible to late diseases. May not be relevant in an area there are not a lot of avocados
3. In my particular case I do not favor a certain taste some creamy avocados have. To me is like an egg salad, canistel flavor. That is me, a lot, lot of people like it. Catalina avocado has it. I prefer the taste of a properly matured Monroe, it has just the right flavor for me. I have seen Monroe trees holding fruit to February, especially if they are not given extra nitrogen.
4. I think Oro Negro will take more cold temperatures than Monroe
If you like the taste it will make a decent tree at home but a lot of people buy trees that have not tasted, only to get disappointed down the road.
