Thank you you all for your advice.. I will be observing it for awhile if it reacts to more water, and have been putting the plant outside for more sunlight. I'm living in a tropical climate with temperatures hovering 28 - 30 degrees celcius and moderate to high humidity. Not sure how those factors may have an effect on the plants. Have checked the roots but I can't tell if the roots have rotted (maybe not obvious enough). Hopefully its not a root problem, I don't see how it can come back to life if thats the case. Thanks again! Thanks again!

well there are plenty of threads on the forum regarding 'the gritty mix' , just put it in the search bar :) If you're looking for a quick temporary fix dunk a whole lot of perlite into the soil...maybe 50/50 ratio. As for the sand, it tends to 'compact' when wet (bad aeration) so it's generally a less popular choice in growing medium. Hope that helps, and goodluck with saving your plant :)

This is what always happens to my C. Muscosa. I'm not really sure how to get that thing to grow roots and keep them there. Am I watering too much, not enough? Is the soil supposed to retain more water? Less water? I would just take. Those pieces with green at the top and bury them up to the first set of undessicated leaves in a well-draining mix and let it reroot. Just don't let it get soggy. I like to use a spray bottle to root succulents.

Hi, Thank you everyone very much! To answer your questions: - Location: Melbourne, Australia - Sun: this area gets a good half a day of direct sunlight - Water/Drainage: This photo as I mentioned, was taken immediately after it rained, so it looks very wet. It is generally well protected from the rain by the leaves. Yes the rocks and sand and coal (i think perlite is another name) is ⅔ of the pot from the bottom. There are 4 big holes in the bottom of the pot and it drains really well. The plants were growing like crazy in this pot for over a year. And I replanted them 3-4 month ago, adding those rocks and sand. So the drainage issue is unlikely. The roots looked healthy. I could put some more rocks on top to protect it from the rain even more. -Plant type: don't know the name, it certainly looks just like K. luciae pictured above in Crenda's comment. There is a different succulent on the side. The very tall fast growing one. The leaves start to develop these black spots or dried edges and then bubble almost in an acid burn looking manner and die off. Should I trim those effected leaves?
