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.
Because peace lily is susceptible to sunburn, it grows best in shadier locations. If you place it in direct sunlight, its leaves will turn yellow before they drop from the plant. Other environmental stresses such as extreme heat or cold and drying winds can also cause plant leaves to react by turning yellow.
