Also called half sphere crassula, rosette crassula.

More about crassula hemisphaerica

Watering at a glance

Base rhythm	When the top 2-3 cm of soil is fully dry, roughly every 10-14 days in growth; less in summer rest
Spring / summer	Spring and summer: soak fully, then leave it alone until the soil is dry all the way down — usually around every 10-14 days.
Autumn	Autumn: ease off as growth slows; stretch the gap noticeably longer than the summer rhythm.
Winter	Winter: water sparingly, roughly once a month or even less in a cool room. The thick leaves carry it through.
Light	Bright indirect light (just back from a sunny window)

About Crassula Hemisphaerica

Crassula hemisphaerica · also called half sphere crassula, rosette crassula · houseplant

Crassula hemisphaerica is a small South African succulent forming tight, geometric rosettes of stacked, rounded grey-green leaves arranged in neat opposite rows. A compact winter grower, it sends up a slender flower spike of tiny white-pink blooms. It wants bright light, gritty fast-draining soil, and careful, infrequent watering. Like all Crassula, it is toxic to cats and dogs.

Ideal humidity: 30-50%

Watch for — Crown and root rot: Soft, blackening leaves at the centre or base follow overwatering or water sitting in the rosette. Water the soil only, improve drainage, and cut watering right back.

The watering schedule, season by season

Crassula Hemisphaerica stores water in its thick leaves and stems, so when in doubt, wait — it survives drought far better than soggy soil. The base rhythm for crassula hemisphaerica is when the top 2-3 cm of soil is fully dry, roughly every 10-14 days in growth; less in summer rest, but the real interval moves with the season, the light and the pot — so treat the figures below as a starting point and always confirm with the plant itself.

Spring & summer (active growth): Spring and summer: soak fully, then leave it alone until the soil is dry all the way down — usually around every 10-14 days.
Autumn (slowing down): Autumn: ease off as growth slows; stretch the gap noticeably longer than the summer rhythm.
Winter (rest / dormancy): Winter: water sparingly, roughly once a month or even less in a cool room. The thick leaves carry it through.

A cool-season grower, it takes more water in autumn and spring and stays nearly dry through hot summer dormancy. Water the soil, not the rosette, to avoid trapping moisture in the tight crown, and let it drain fully.

How to tell crassula hemisphaerica needs water

A calendar is the worst way to water crassula hemisphaerica. Check the plant and the soil instead — for this species, look for these signals in order:

The lower or oldest leaves feel slightly soft or look a touch wrinkled.
The pot is noticeably light when lifted.
Soil is dry several centimetres down, not just at the surface.

The most reliable single check is the first one on that list. When two signals agree, water; when they disagree, wait a day and look again — under-watering crassula hemisphaerica for a day is almost always safer than over-watering it.

Overwatering vs underwatering crassula hemisphaerica

The two failure modes can look alike at a glance, so check the soil weight and wetness before you decide. For crassula hemisphaerica specifically:

Signs you are overwatering

Leaves turn translucent, yellow, soft and mushy — classic overwatering.
Lower stem darkens or goes squishy at soil level.
Whole rosettes or sections drop at the lightest touch.

Signs you are underwatering

Leaves pucker, wrinkle or curl inward — a harmless thirst signal that reverses fast after a soak.
Older leaves dry crisp from the tips first.

Overwatering is the number-one killer of crassula hemisphaerica. The thick leaves are a water tank — a slightly thirsty plant recovers in a day; a waterlogged one rots from the roots up.

Water quality notes

Tap water is generally fine for crassula hemisphaerica; the soak-and-dry rhythm matters far more than water type.

Seasonal and environmental adjusters

Every figure above shifts with the conditions in your home. For crassula hemisphaerica, the levers that matter most are:

A gritty, free-draining mix is essential — ordinary potting soil holds too much water for this plant.
Terracotta dries faster and is more forgiving than plastic or glazed ceramic.
More light and warmth speed drying, so the interval shortens in peak summer — always check, never assume.

Pot choice is part of this too — work out the right size with the pot size calculator, since a pot that is too big stays wet long enough to rot the roots of crassula hemisphaerica.

Crassula Hemisphaerica watering — frequently asked questions

How often should I water crassula hemisphaerica?

Water crassula hemisphaerica when the top 2-3 cm of soil is fully dry, roughly every 10-14 days in growth; less in summer rest. Spring and summer: soak fully, then leave it alone until the soil is dry all the way down — usually around every 10-14 days. Winter: water sparingly, roughly once a month or even less in a cool room. The thick leaves carry it through.

How do I know when crassula hemisphaerica needs water?

The lower or oldest leaves feel slightly soft or look a touch wrinkled. The pot is noticeably light when lifted. Soil is dry several centimetres down, not just at the surface. The single most reliable test for crassula hemisphaerica is the first signal on that list — checking the soil or the plant directly always beats watering by the calendar.

What does an overwatered crassula hemisphaerica look like?

Leaves turn translucent, yellow, soft and mushy — classic overwatering. Lower stem darkens or goes squishy at soil level. Whole rosettes or sections drop at the lightest touch. Overwatering is the number-one killer of crassula hemisphaerica. The thick leaves are a water tank — a slightly thirsty plant recovers in a day; a waterlogged one rots from the roots up.

What are the signs of an underwatered crassula hemisphaerica?
