String of Hearts Care Guide
Ceropegia woodii
By Ellen Hermance · PlantCareAI Editorial
String of Hearts is a trailing succulent-like vine from southern Africa with delicate heart-shaped leaves patterned in silver, green, and purple. Its thin cascading stems can reach several feet long, making it one of the most striking plants for hanging baskets and high shelves. It stores water in its leaves and tuberous roots, giving it excellent drought tolerance. The combination of beauty and forgiveness makes it a favorite among collectors and beginners alike.
Quick Care Reference
| Care Aspect | Requirement | Frequency |
|---|---|---|
| Watering | Soil fully dry | Every 1-3 weeks (seasonal) |
| Light | Bright indirect + some morning sun | Avoid intense afternoon direct sun |
| Humidity | 30-50% (adaptable) | No special treatment needed |
| Fertilizer | Half-strength balanced or high-K | Monthly spring/summer only |
| Repotting | Well-draining cactus mix | Every 2-3 years |
Watering
Water thoroughly when the soil is completely dry, typically every 7 to 14 days in spring and summer. In fall and winter, reduce to every 3 to 4 weeks. The vine stores water in its leaves and small tubers along the stems; it is far more forgiving of underwatering than overwatering. Bottom watering works very well: set the pot in a shallow tray of water for 15 to 20 minutes, then drain fully. Always use a pot with drainage holes.
Light Requirements
String of Hearts needs bright indirect light to maintain its distinctive silver and purple variegation. An east- or west-facing window is ideal. A south-facing window works well with a sheer curtain to diffuse intense afternoon sun. In lower light, the leaves lose their silver patterning and spacing between leaves becomes wider as the plant stretches. A few hours of gentle direct morning sun is beneficial and encourages compact growth and more vibrant coloring.
Humidity & Temperature
String of Hearts tolerates average home humidity (30 to 50%) without any special care. It does not need misting or a humidifier. Keep temperatures between 60 and 80°F (15 to 27°C). It is not frost tolerant; brief cold below 50°F can cause leaf damage. Avoid cold drafts from windows in winter.
Fertilizing
Feed once a month in spring and summer with a balanced or high-potassium liquid fertilizer diluted to half strength. High-potassium formulas encourage more compact, colorful growth. Do not fertilize in fall or winter. Avoid over-fertilizing, which causes elongated growth with widely-spaced leaves.
Propagation
String of Hearts is one of the easiest plants to propagate, whether from stem cuttings or by using the small aerial tubers that form along the vines.
Stem cuttings in water
- Cut a section of vine with 3 to 4 leaf pairs
- Remove the bottom 1 to 2 pairs of leaves
- Place the bare nodes in a glass of water in bright indirect light
- Roots appear in 2 to 3 weeks; change water every few days
- Transfer to cactus mix once roots reach 1 inch
Aerial tuber pressing
- Identify the small round tubers (beads) that form along the vine
- Without cutting, press the tuber against moist cactus mix in a small pot
- Keep the tuber in contact with the soil using a hairpin or small weight
- Roots will emerge from the tuber within 2 to 4 weeks
- Once rooted, cut the vine connecting it to the mother plant
Popular Varieties
Ceropegia woodii 'Variegata'
Leaves edged in cream and pink; slightly more delicate than the standard form.
Ceropegia woodii f. woodii
The standard form with silver-patterned green leaves and purple undersides.
Ceropegia linearis
Narrow, strap-shaped leaves rather than heart-shaped; same care requirements.
Seasonal Care Calendar
Spring
Mar – May
- Resume watering every 1 to 2 weeks as growth picks up. Begin monthly fertilizing.
- Active growth period. Water when soil is dry and feed monthly.
- Look for new stem growth. Take cuttings now for propagation.
Summer
Jun – Aug
- Water every 1 to 2 weeks. Continue monthly fertilizing.
- Keep out of intense afternoon sun. Soil dries faster in warm rooms.
- Vines grow actively. Trim if desired and root the cuttings.
Fall
Sep – Nov
- Reduce watering to every 2 to 3 weeks. Stop fertilizing.
- Growth slows. Allow soil to dry more fully before watering.
- Move away from cold windows. Water every 2 to 3 weeks.
Winter
Dec – Feb
- Water every 3 to 4 weeks or less. No fertilizer.
- Minimal care. Check soil before watering; it dries slowly.
- Continue infrequent watering. Bright light helps maintain leaf color.
Troubleshooting
Yellowing or mushy stems
Why it happens: Overwatering or root rot
What to do: Remove rotted roots and stems, let dry, and repot in fresh cactus mix. Reduce watering frequency.

Why it happens: Insufficient light
What to do: Move to a brighter location. Variegation and color intensity return with better light.

Why it happens: Low light or over-fertilizing
What to do: Increase light and reduce fertilizer. Trim elongated stems and propagate the cuttings.
Crispy shriveled leaves
Why it happens: Underwatering or low humidity
What to do: Water more frequently and move away from heating vents.
