Join me today as I talk about yellow leaves on fruit trees and why it may or may not be a fertilizer issue. A friend contacted me about a black spot developing on the surface of his saguaro and if he should be concerned. How to prune bougainvillea when it does survive the winter or when it doesn't. And where to get some of the fruit trees I recommend and what time of year you should do it. Join me as I talk about these topics and more on Desert Horticulture.
