Succulent plants continue to be very popular amongst gardeners everywhere because of their unusual and architectural forms and thriving with very minimal watering. The Aeoniums are one of the most iconic of all succulents. Unfortunately, they are not hardy in the Pacific Northwest, but they are excellent container specimens that are actually pretty easy to overwinter if cared for properly indoors.
The key to success with any succulent is bright light, very well-drained soil and limited watering during the growing season. They respond to being fertilized on a regular basis during active growth (for us it’s June-September) and then as cold temperatures approach, they are dug up before the first frost and potted up and kept indoors where it can stay cool, but not freezing. Some growers overwinter them “bareroot” and will mist them occasionally so they don’t dry out. The more light you can give them during this pseudo-dormant period the better.
