After putting the leaves on soil to allow them to root properly, it became evident that my light source was less than adequate. I had been keeping them on a bench inside my hone with a grow light about 1.5 feet to 2 feet above them. Not only was it not enough light for them, but it was getting very hot as well.
Many of my baby succulents are very tall and lanky, but they are now all sitting in my bedroom windowsill where they get direct afternoon sunlight. They all seem to be doing much better, although none of them are fully established yet.
I also continue to add more succulent leaves, as they fall off the mother plant, or as I get new plants, so my tray of succulent babies continues to produce new plants! Today I added some pork and beans, burro's tail, and jade as well as a couple unknowns.
