So I recently discovered that my elephant bush and ghost plants had grown some mold on the tops of their soil. I decided to get rid of half the soil and replace it for my elephant bush and just completely replace the soil for my ghost plant since it’s pretty small. I thought I was watering them when they were completely dry but they were still pretty damp at the bottom of their pots so that kinda sucks. Other than that they look ok and I’m letting them dry out for as long as possible. I’m keeping an eye on my other succulents just in case but the others are fairly new and have only been watered maybe a couple of times. Decided to get a moisture meter to prevent this from happening again. Any other advice for my plants?
