I purchase this plant from you about 6 weeks ago. Soon after planting it started to not look well… The bottom leaves almost immediately started to yellow/brown and shrivel up. Now the tips of almost all the leaves are turning black. Is it too much water? It is in full sun almost all day and I have been watering every week or two.
Your Graptopetalum has sun burn. We had it here out in full sun, but there have been foggy mornings so it may be that you just have a lot more sun where you are than us. However the good news is that there are new leaves growing out of the center of the plant that are nice and clean and used to the amount of sun you have, so the plant will be fine. You can remove the old leaves if you like, or leave them in place until they start to shrivel off.
