Three popular questions I was sent include improving the size of Bartlett pears, whether a pomegranate can be planted during the winter or not, and what are whiteflies and what damage do they create? In this episode I talk about the three major types of pears that can be grown in the Mojave Desert, how to get them bigger and when to pick them. I also talk about the best times to plant a pomegranate and what to be careful about. Finally, one reader didn't understand what whiteflies were, how to control them and the problems that they create. All this and more on this episode of Desert Horticulture.
