String of Hearts care guide
Ceropegia woodii
Easy care✅ 🐾
String of Hearts (Ceropegia woodii) does best when watered about every 14 days. It stores moisture well, so let the soil dry out completely between waterings — overwatering is the fastest way to kill it.
Place it in bright indirect light. Humidity needs are low. The comfortable temperature range is 15–26°C. During the growing season, feed it about every 30 days.
Care difficulty: easy — great for beginners.
✅ Pet safety: String of Hearts is non-toxic to cats and dogs — non-toxic.
String of hearts is a semi-succulent trailer: it stores water in its thick heart-shaped leaves and in a woody tuber sitting at the soil surface, so it wants to dry out completely between waterings, roughly every 14 days. Along the strands it also forms small bead-like aerial tubers at the leaf joints, which root the moment they touch soil and are the easiest way to propagate it. The silver marbling on top of the leaves and the purple undersides depend on light: in a dim spot the leaves go plain green and the gaps between them stretch. Treat it like a succulent that hangs, not like a tropical vine, and skip the misting entirely.
Common problems and fixes
String of hearts losing its pattern
Why: Too little light. The silver marbling fades, leaves turn plain green and grow further apart along the strand.
What to do: Move it into bright, indirect light close to a window; a couple of hours of gentle morning sun is fine. The new leaves will come out patterned again, the old ones won't change.
Yellow, mushy leaves and strands rotting at the soil
Why: Overwatering. The tuber and roots rot in soil that stays wet, especially in a pot without drainage or in cool winter conditions.
What to do: Stop watering and check the tuber: firm is fine, soft and dark means it's rotting. Take cuttings from the healthiest strands straight away as insurance, then repot the rest into a gritty cactus mix.
Leaves thin, soft and wrinkled
Why: Usually thirst: the leaves use up their stored water and deflate. If the soil is wet and the leaves still wrinkle, the roots have rotted and can't take up water.
What to do: Feel the soil. Bone dry means a thorough soak and the leaves plump up within a day or two; wet soil means checking the roots and tuber for rot.
Bare top, leaves only at the ends of the strands
Why: Normal ageing combined with low light: the plant puts its energy into long strands rather than new shoots from the crown.
What to do: Coil a few strands back over the soil and pin them down, or push aerial tubers into the top of the pot. They root in a few weeks and fill the crown from the top.
White fluffy spots at the leaf joints
Why: Mealybugs, which love the tight joints between leaf pairs.
What to do: Dab each cluster with a cotton bud dipped in rubbing alcohol and repeat weekly for a month. Badly infested strands are easier to cut off and replace with fresh cuttings.
Care through the seasons
☀️ Spring and summer
From spring to late summer the strands can grow several centimetres a week and tiny lantern-shaped pinkish flowers appear. Water about every 14 days, only when the soil is completely dry right through, and feed once a month with a half-strength fertiliser for succulents or houseplants. This is the best time for cuttings and for coiling strands back into the pot.
❄️ Autumn and winter
In autumn and winter it goes semi-dormant. Water much less, every three to four weeks, stop feeding and give it the brightest spot you have, since winter light is weak. It tolerates a cool room down to about 15 °C, but cool plus wet soil is the fastest way to rot the tuber, so water sparingly on bright days.
How to propagate
The easiest way uses the aerial tubers. Take a strand with a tuber, lay it on a small pot of moist cactus mix and pin the tuber against the soil with a bent paper clip. It usually roots within 2 to 3 weeks, and you can snip it free from the mother plant once it resists a gentle tug.
Stem cuttings also work well. Cut 10 to 15 cm lengths, strip the leaves from the lowest node or two and either stand them in water or lay them flat on moist gritty soil; roots appear at the nodes in a couple of weeks. Plant several cuttings in one pot for a full look, since a single strand stays sparse for a long time.
Tips from experience
- Don't mist: it is a low-humidity plant and wet leaves only invite rot.
- Use a gritty mix (cactus soil plus perlite) and a pot with drainage holes; terracotta is ideal.
- Keep the woody tuber at the soil surface, never buried deep.
- Hanging high near the ceiling means warmer air and faster drying, so check the soil more often there.
- Trim very long, bare strands and replant them as cuttings to keep the pot full.

▸How often should I water String of Hearts?
About every 14 days. In winter or lower light, stretch the interval; in hot bright rooms, shorten it slightly. Always check the soil first.
▸What light does String of Hearts need?
String of Hearts prefers bright indirect light, with a comfortable range of 15–26°C.
▸Is String of Hearts toxic to cats and dogs?
No, it is considered safe for cats and dogs. Non-toxic.
▸How often should I fertilize String of Hearts?
Roughly every 30 days during spring and summer; pause or halve feeding in winter.
▸What are the little balls on my string of hearts?
Those are aerial tubers. They store water and nutrients, and any tuber pressed into moist soil will root and become a new plant.
▸How often should I water string of hearts?
Roughly every 14 days in spring and summer, and only when the soil is completely dry. In winter every three to four weeks is enough. Plantik uses a 14-day reminder that you can lengthen for the cold months.
▸Why is my string of hearts turning plain green?
It needs more light. The silver pattern and purple tones only develop in bright, indirect light; new growth will colour up once you move it closer to a window.
▸Is string of hearts safe for cats?
Yes, Ceropegia woodii is non-toxic. Cats do like to bat at dangling strands, though, so hang it out of reach if you want it to stay long.
