Thanks to Sweetstuff and a few other readers, my little crassula ovata gollum, which I started from a wee cutting, is making a comeback! I repotted it into a bigger container with more drainage, new soil, and a nice long drink of water. I also pinched off one or two of the leaves at the bottom that were the most shriveled. On the left is a picture of what it looked like on 10/7, when I asked for your help. On the right is a picture of it yesterday:
Can you believe the difference? It went from being a shriveled little plantlet to plumping up and being well on its way to a happy, well-adjusted little plant in less than a week! Thanks for your help, fellow succ-ers!
