Hi stairbender, and a big
to NGA. So glad you found your way here.
Your first photo shows a relatively healthy sempervivum, with an infestation of mealybug. Semps rarely have problems with pests unless they are stressed. If you are keeping it indoors that would be very stressful to a semp. They do not do well indoors.
Notice the difference in coloring between your first photo and the next two photos. The plant has become very pale/anemic looking. It also looks like it has the beginnings of rot.
I also notice that your potting mix looks to be mainly forest/peat product. This also does not make for a happy semp. You can start with a small bag of Potting Mix (there are several good brands out there), add coarse sand (about 40 to 50%) and some pumice or chicken grit. After planting add a nice layer of chicken grit (Cherry Stone #2 is a nice size).
Before planting remove any rotting tissue and lay on a clean paper towel to dry/callus over for a day before replanting.
Water thoroughly and place outside in bright light, not direct sun.
Hope this was helpful?
