About String of hearts

Ceropegia woodii · also called rosary vine, sweetheart vine · houseplant

String of hearts is a delicate trailing succulent from southern Africa with heart-shaped silver-marbled leaves on thread-thin stems. Easy from cuttings and tolerant of dry conditions. Pet-safe and a popular shelf and macrame trailer.

Ceropegia woodii (Apocynaceae), native to southern Africa from Zimbabwe and Eswatini into eastern South Africa, a trailing succulent vine of rocky, well-drained ground.

It tolerates dry soil far better than wet and is easily killed by overwatering, which rots its tubers; water only when the medium is essentially dry.

Ideal humidity: 40-60%

Watch for — Mushy leaves at the crown: Overwatering; cut affected strands and reduce frequency.

The watering schedule, season by season

String of hearts 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 string of hearts is when soil is dry, every 10-14 days, 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.

Succulent leaves and tubers store water; rot is fatal.

How to tell string of hearts needs water

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

Overwatering vs underwatering string of hearts

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