winter dormancy on Aeonium
Quick answer
If your Aeonium has winter dormancy, the most likely cause is: Aeonium species are winter-growers native to the Canary Islands and Mediterranean, evolved to be dormant during hot, dry summers and active during cool, moist winters. When kept indoors in climates with winter heating, Aeonium often fails to receive the summer dormancy trigger (temps above 85°F sustained), yet may receive winter cues (temps below 60°F and reduced light) that signal dormancy. This creates confusion where the plant slows in December-February despite being a winter-grower by heritage.
Start here:
- 1. Recognize Aeonium as a winter-grower: It actively grows October through April in Northern Hemisphere conditions, so continue watering every 2 weeks during this period if the plant shows growth.
- 2. During summer (June-August): Reduce watering to near-zero if temps exceed 85°F regularly — this is when Aeonium naturally enters summer dormancy.

How to reverse winter dormancy on Aeonium
- 1
Recognize Aeonium as a winter-grower: It actively grows October through April in Northern Hemisphere conditions, so continue watering every 2 weeks during this period if the plant shows growth.
- 2
During summer (June-August): Reduce watering to near-zero if temps exceed 85°F regularly — this is when Aeonium naturally enters summer dormancy.
- 3
If Aeonium shows unexplained leaf drop or slows in winter, check root health first — the plant may be experiencing root rot from overwatering rather than natural dormancy.
- 4
Provide bright light even in winter — Aeonium etiolates easily when light is insufficient, producing widely spaced leaves (rosette gap) that indicate the plant is reaching for more light.
- 5
In spring, Aeonium may produce tall flower spikes — this signals the end of the active growth cycle and the plant may die back after flowering (normal monocarpic behavior).
Keep winter dormancy off this Aeonium
Understand that Aeoniums are opposite of most succulents — they grow October through April and rest May through September. If your Aeonium shows slowing or leaf drop in fall/winter, it may be signaling improper conditions rather than natural dormancy.
