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.
Yellow leaves are often caused by soil that is too dry; the reason soil that is too wet can also cause yellow leaves is that overly wet soil promotes root rot, which destroys the roots so they can't bring water to the leaves, so the leaves get yellow, just as they would if the soil were dry.
