Q.My crassula marnieriana’s leaves have gone black and dried up – what do I do?
Starting from the base the leaves have gone black and dried out. Most are still ok at the tips but am very concerned. Have moved it to an area with more light – will that help? Have included a photo from when I first got it (three months ago) so you can see the change. Please help!!

Some dieback is normal, but this does seem like a lot. If it's not mushy, it may not be rot. You can prune off the dead stems and notice if there is any soft rot. If so, you can unpot the plant and remove the rotting parts and repot the healthy foliage. To be on the safe side, you can also cut off a couple cuttings to air dry for a week, then pot up to make a new plant.
Check your potting mix. Make sure you have a good succulent mix that is quick draining. Also let the soil dry out between waterings.
