Is this root rot?
I've had this young (not sure how young) desert rose since late July. There are still some healthy green leaves on it, although it seems that one falls off every week or two. I know that as it is winter in NY, she's entering dormancy, so I'm not worried about her losing leaves. What does make me worry a little is the slight discoloration right above the root ball. That area is also a little soft, and the root ball feels slight moist (even though I haven't watered her in 2-3 weeks). I just repotted her with a cactus soil/sand mix and have placed rocks at the bottom of the terracota pot.
Do any of you think I should be concerned?
