@mauspad - Ooh that's the problem. Agavoides, unlike other Echeveria are summer dormant and winter growers. It's always best to not water and keep agavoides in filtered light. Was it you who asked me what conditions I kept mine in?
@mauspad some don't like water on their leaves and others are more susceptible to mealy and others like a lot of water!! Echeveria Bi-colour being one of those. My Echeveria are like my kids, each seems to like their own little thing. I tweak and tweak until they are happy. But agavoides are the main winter grower.
