This Haworthia succulent is a great way to treat your brain as well as your body. Scales can also be treated the same way you treat mealybugs. Scales do not need much attention. It can be left alone to thrive and grow as long it is hydrated regularly. Echeveria dondo blooms early, which is unusual for succulents. The Echeveria dondo is more at home outdoors, but you can also grow it indoors. By avoiding watering in the afternoon, you avoid having hot water seating on the plant, possibly burning the plant. The reason your leaves curl is likely because the soil is dry.
