Oh, so sorry!
I had a bunch of lower leaves on my new babies go brown & crispy... realized it was only happening in the planters where I hadn't mulched with sand, where the leaves were in contact with damp potting mix. Now all the little semps have sand (coarse builder's sand, not play sand) surrounding them, and they're only in direct contact with the potting mix at the center/base of the rosette, so they can put down roots better. This seems to be working so far...
So when/if you put some back in the ground, try mulching with coarse sand or pea gravel so the edges of the rosette don't touch "regular" soil. Maybe that will help even if they get over-watered.
