Echeveria Laui lost its coating
Hello! I have just started to cultivate succulents and I think I have already made my first mistake. My laui got mealy bugs, so I went at my local gardening store and bought a bottle of pesticide. But after the first spray my plant lost almost all of the protective powder. Is there any chance it will restore the coating with time? And more importantly, are there any precautions I should take?
