My wife got three different succulents from a friend for her birthday. One of them started turning brown on the stems and tips of leaves about a week ago.
She's been watering them consistently (checked the soil this morning and it's damp), and it is possible that she overwatered them. From what I've read, though, it doesn't look like overwatering. Can anyone shed some light on this? What is happening to our succulent and how can we cure it?
