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.
Even plants that prefer full sun can get too hot. If your morning glory's leaves turn yellow at the margins or between the leaf veins, it may be suffering from leaf scorch. The primary cause of leaf scorch is the plant's inability to draw up sufficient water.
