I'm having major problems with my Black knight echeveria. It doesn't like being outdoors in varying light conditions. It doesn'tlike being indoors in varying light conditions. It hasn't been over watered or under watered and yet it still isn't doing well. Echeverias are not my forte but I love the color and shape of this guy. No stretching but all the lower leaves just kept dying. I've recently beheaded him. He's calloused over and is sending out roots. Also the leaves are propagating. Does anyone have any advice. This plant has literally done a 360 degree roundabout of my house inside and out. Oh and the stem is shooting off plants too. So no root rot. Any advice?
