Q.Houseplant Echeveria
I bought two echeveria from a garden store. I put them in the bathroom but the hot steam made the leaves fall off one of them. I have changed its soil and dried out its roots as it has a little leaf budding from the bulb. The second one the leaves lowered from the upright rosette it had when I bought it. I changed that soil too. I wonder how to locate them in the house. Is the east facing window better for them to thrive?
