My Aeonium "zwartkopf" is a plant that I've always had a hard time with. I was just given one as a gift about a month ago. I treat it the way I treat my other succulents, but for some reason, they always end up doing poorly. The leaves will start curling downwards - that's always the first thing that happens... My current one has just started showing the downward curling leaves (see the pic). It's in a very high quality bonsai soil (drains extremely well), and it resides in an East facing window. Could it be that it's receiving too much direct sunlight/heat? According to what I've read that is one cause for the leaves to do this. Other sources say that the plant needs to go dormant during summer, as in their natural habitat, they are winter growers... Any advice would be appreciated!
