Which would you say is the better, higher quality variety to grow as a dooryard tree?
In the real world.... I am at a nursery and between Lula and Day I am going to buy the strongest looking tree. All things being equal I would go for Lula because it is good tasting and has a season I like. October into December-January. And I have seen February stragglers one year.
How come you see Lula at Pine Island avocado viewer but not Day? I think Lula is the most commonly planted backyard avocados here...after seedlings! Of course!
