Species file
Genus · Aeonium
Aeonium
winter growers with a strict summer shutdown. One file in the collection so far — Aeonium arboreum 'Zwartkop'. Dormancy for the whole genus falls in June, July, August, September.
| Month | State | What the plant wants |
|---|---|---|
| January | Growth | Deepest rest. Water only if the lowest leaf ring softens; keep the room as bright as you can. |
| February | Growth | Late rest. Daylight is returning — begin adding an hour of supplementary light every two weeks. |
| March | Growth | Repotting window opens for summer growers. Trim roots, refresh the mineral fraction, dry for a week. |
| April | Growth | Growth restarts. First full watering at the rim, then resume the published interval. |
| May | Growth | Peak growth and the offset season. Feed at quarter strength every third watering. |
| June | Rest | Out of action for this genus — no water unless the plant visibly shrinks, and no repotting. |
| July | Rest | Out of action for this genus — no water unless the plant visibly shrinks, and no repotting. |
| August | Rest | Out of action for this genus — no water unless the plant visibly shrinks, and no repotting. |
| September | Rest | Out of action for this genus — no water unless the plant visibly shrinks, and no repotting. |
| October | Growth | Peak autumn growth. This is the season when most colour work should be done. |
| November | Growth | Daylight falls fast. Taper watering by a quarter and stop feeding entirely. |
| December | Growth | Slow, dry and bright. This is the colour peak for most genera in the collection. |
Tinted rows are the months this genus is genuinely out of action: no repotting, no feeding, and water only if the plant visibly shrinks.
