Once the fruits are set, they shouldn’t fall. If they do, then you may be doing something wrong. You may have set too many, over watering, or not enough fertilizer to name a few.
@thenoobgardener . I am new to this. I actually only have eight. I live in Las vegas. I put them in the greenhouse bc it's too dry in las vegas. I maintained the humidity between 65-75%. I only watered once it's dry.
8 fruits? Then maybe your tree can handle 8 fruits at the moment. My trees can only handle around 20 at the moment. When I first started, they could only handle 1-2 fruits max.
