The Tropical Fruit Forum

I'm going to grow mine in a warm low humidity greenhouse. But not many people have experience with that. Can anyone venture a guess about fungal issues in really dry climates. California is wet in winter, Florida basically all yr long. But how about a real desert where it doesn't rain much anytime of yr. Would that still have powdery mildew or other fungal issues on mango? I have seen PM on grapes and melons in really dry conditions. But usually diseases of the tree or fruit are wet weather issues.
