Desert rose dormancy question.
I have several desert roses in cactus potting mix in terra cotta pots on the north side of my house. I have not watered since the temperatures at night have dropped into the low sixties and highs are about 80. So maybe two weeks now.
The sun has dropped low enough in the past week or so to put the plants into shadow for quite a few hours each day. They still get 6 hours or so though. Since then, the leaves have turned yellow and falling off, like if the plant were rotting.
Are these plants partially deciduous or dormant in the winter? If so, maybe the house shadow falling on them all the sudden is to blame. If I just move them to the south facing backyard where they will get PLENTY of light, will they wake back up? Thanks.
