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.
The plants are in pots, not in the ground. The soil in the pots is peat-based potting mix. We have had quite a bit of rain here, but still a good amount of sunshine.
