Microthrix, thanks for responding :) :) :) I searched photos of this plant online and noticed that some are much more compacted (or maybe incorrectly categorized). Are my plant's leaves long and the stock tall because of stretching? I just thought this is how the plant was supposed to look like (since I've never seen it before). I actually prefer the look of mine. My friends call them "bunny ears." There are some new growths. Picture--> http://instagram.com/p/bc7eUOvBlr/ I can't wait to take some cuttings and propagate them. I haven't seen them anywhere else, so I have to be careful to keep my one-of-a-kind (in my garden) plant healthy.

Yes, they are mealy bugs. The first step is definitely to quarantine any affected plants. Make sure you really check all your plants, not just the ones where they are readily visible, because they can be expert hiders. Leaf or surface mealy bugs are different from root mealy bugs, but it is possible to have both. I would try pulling up a plant or two to check; if you don't see anything, you probably only have the surface bugs. Treatment can be a bit of a pain, but you can find lots of information on what solution to use on the forum. I have used a 50/50 water/alcohol mix with a squirt of dish soap, and I'm currently experimenting with Safer's Insecticidal Soap. So far it seems to be working well. Definitely make sure you spray and/or remove what you see, but I always like to spray the whole plant in case there are things I can't see going on. Because soaps and pesticides often work on certain, but not all, parts of the life cycle, you will have to do several treatments. The life cycle is around 3 weeks. I like to spray once every few days (spraying every day seems too hard on the plant, in my experience). Then, be sure to keep your plants quarantined for a few more weeks to be sure all the bugs are gone before you put them back with the rest of your collection. Good luck!

Rudi, Sadly, your picture is a bit too blurry to tell what's going on. Are the white spots removable with water? Are they fuzzy? Do they move? A clearer picture would help. Planto

Even if the water is isolated, I would still remove it. It is going to keep evaporating, creating more humid environment, which succulents hate, and creates higher risk of fungus infection. The plants should be separated into their own pots. If you keep them all in that pot, later as their roots will grow, they will get tangled around other plants roots, possibly strangle each other and create more infection-prone environment at the same time. And then it will be significantly harder to separate those plants, without heavily damaging their root system. Another problem that I see with keeping them all in that one pot is that you got heavy-direct sun liking plant there, Echeveria, combined with only indirect (or small amount of direct) sun liking plants, such as Haworthia. I prefer to use clay pots, but whichever you decide to use, it must have drainage hole. For soil, all the plants that you have there will do well in a mixture of silica sand (not fine sand), perlite and some peat moss. Make sure that the peat does not make up more than 50% of your soil mix, like many store-bought "cactus/succulent soils" contain.
