Desert Rose Leaves Turning Yellow and Falling Off. The leaves on my desert roses in the front of the house, which doesn't get sun until 11 am (western exposure), are turning yellow and falling off. They do get a couple of brown spots on some of them before they turn yellow. I have sprayed them with fungicide a couple of times.
Few things destroy the look of a houseplants or a lush garden quite as unassumingly as yellow leaves. A number of problems can cause a plant's leaves to turn yellow, such as too much sun, lack of nitrogen, iron chlorosis or pest infestations, depending on the type of plant and its current habitat.
