Possible disease on Caribbean Copper Plant

Pasadena, CA

I've had my Caribbean Copper plant for almost a year now, and when I was repotting it, I noticed that there were some small dark spots on the branches and some of the leaves look like they're yellowing. Should I be concerned?

Yellowing can be a sign of overwatering, and it looks like it's drooping a bit too which can also indicate overwatering. Those can both be signs of underwatering as well, but overwatering is more common, plus it looks like the pot you have it in might be a bit on the big side for the plant and that makes it even easier to accidentally give it too much water. I'd try sticking your finger down a little way into the soil and see how it feels, if it's really wet then that's your problem. Or if it's not too wet, if you just disturbed the roots a bit during repotting it could just be suffering a little transplant shock (drooping and yellowing can be symptoms of that as well)

Actually I just transferred it from the ground. It was planted in some hard clay soil which didn't seem to be treating the plant very well. It's been really hot where I live, ranging from 85 -95, and it's mostly in direct sun. It may be the overwatering thing, so I will try to regulate that. I guess I'm more worried about the spots on the branches.

Could still be transplant shock too, chances are it lost a few roots in the process of digging it up from the ground. Or it could be stress from suffering in clay soil too, it'll take it a little time to perk up from that. I would still check on the watering though, it's so easy to overwater plants. I can't really see the spots on the branches that well from the picture, but dark spots are often fungal in nature and if the plant was in clay soil and staying too wet that could have done it. I'd also move it out of direct sun for a bit and put it somewhere cooler and shady, that will help it recover faster. Then once it's perked up, you can gradually adjust it to being in more sun again.
