Laura It shouldn't be difficult to separate them - there seems to be lots of space between individual plants. You can behead them - chop off top part of plant (best to use sharp knife), let callous and pot up. You can pot up lower part (leftover trunk with roots) & you could get some new babies sprouting from it. It would be good to improve your potting mix, this one looks pretty peaty (hard to tell from your photo). They would enjoy more gritty mix - much better drainage. There are some skinny & tall plants in the background - are they succulents? Edited to add: here is a thread with very similar question and good photos: beheading echeveria Howard (bikerdoc) is giving excellent advice & photos showing 'leftover' trunks growing new plants.

Many thanks my friend. I'll check that out tomorrow, (it's bedtime here.) Really appreciate your quick response.

Looks like a spider sac with a covering over it nestled in the groove of the leaf. However, that is a weird place for a spider egg sac. Or, it might be some kind of weird rot that I wouldn't want any where near the rest of the plant. I can't be sure. I need more detail in the picture. I'm leaning toward spider egg sac.

Kelsey Do not only take plants out to dry out (but perhaps you mean out of the cachepots?) - if you have outdoor space, leave them outside for whole summer. Succulents need to be acclimatized to outside, and that could be accomplished in a week right now. After that, they will grow much better than indoors. Your cachepots are very nice, I am sure displaying plants in them looks better than plastic pots, especially if you are using them as décor throughout the house (I wouldn't get any awards for décor, lol. Vast majority of my pots are plastic, few are terracotta). That is personal decision, but be aware that even if you don't see it heat will build up in that small space, can't escape and keeps plastic pot damp longer. Leaving them out (plastic pots) for few hours after watering definitely helps (while wouldn't do it with many plants I have). This is not a criticism, just helpful hints.
