Hi there, I've heard many times that it's impossible to make avocado fruit in central Europe - the Czech Republic to be precise - (potted or in a greenhouse) and that it has something to do with pollination or duration of the sunlight or something along these lines. But nevertheless, I keep finding a lot of articles on how to make avocados fruit in my native language. And I just keep wondering why exactly is it impossible to make avocado bear fruit here, but you can for instance grow a variety of other exotic fruit trees that bear fruit without any problems (such as mangoes, sapote, papaya, etc.)? Is this true then? And if so, what exactly makes it impossible?
