Species file

Sedum month by month
MonthStateWhat the plant wants
January Rest Out of action for this genus — no water unless the plant visibly shrinks, and no repotting.
February Rest Out of action for this genus — no water unless the plant visibly shrinks, and no repotting.
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 Growth Lengthening days, rising heat. Watch the leaf turgor test rather than the calendar.
July Growth Hottest weeks. Water in the evening, a third of the spring volume, and only on a visible symptom.
August Growth Heat eases at night. Prepare mix and pots for the autumn repotting window.
September Growth Autumn window for winter growers. Root-prune and repot while the soil is still warm.
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 Rest Out of action for this genus — no water unless the plant visibly shrinks, and no repotting.

Tinted rows are the months this genus is genuinely out of action: no repotting, no feeding, and water only if the plant visibly shrinks.
