Base rhythm	When the top of the soil is dry, roughly every 10-14 days in summer; every 3-4 weeks in winter
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.

About Curio Rowleyanus

Curio rowleyanus · also called string of pearls, rosary plant · houseplant

Curio rowleyanus, the string of pearls, is a trailing South African succulent (formerly Senecio rowleyanus) with cascading stems of spherical, pea-like leaves, each with a translucent 'window' to harness light. Grown in hanging pots for its waterfall of beads, it needs bright light, very lean draining soil and careful, infrequent watering, as its delicate strands rot easily if kept wet.

Ideal humidity: 30-50%

Watch for — Overwatering and root rot: Pearls that burst, turn mushy or yellow and strands that collapse signal too much water. Let the mix dry fully and ensure free drainage.

The watering schedule, season by season

Curio Rowleyanus 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 curio rowleyanus is when the top of the soil is dry, roughly every 10-14 days in summer; every 3-4 weeks in winter, 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.

Water thoroughly then let the lean mix dry before the next drink. Shrivelled, deflating pearls mean it is thirsty; mushy, bursting pearls mean overwatering, which quickly rots the shallow roots.

How to tell curio rowleyanus needs water

A calendar is the worst way to water curio rowleyanus. 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 curio rowleyanus for a day is almost always safer than over-watering it.

Overwatering vs underwatering curio rowleyanus

The two failure modes can look alike at a glance, so check the soil weight and wetness before you decide. For curio rowleyanus 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 curio rowleyanus. 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 curio rowleyanus; 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 curio rowleyanus, 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 curio rowleyanus.
