How to Grow String of Hearts
Ceropegia woodii
String of Hearts is a trailing semi-succulent grown for its delicate heart-shaped leaves on long, thin stems. It thrives in bright indirect light with very infrequent watering — let the soil dry out completely between waterings. Plant in free-draining cactus compost and keep above 10°C year-round. The biggest mistake is overwatering, which causes fatal root rot.
Yearly Lifecycle
Care Essentials
Feed monthly with a diluted cactus or succulent fertiliser during spring and summer only. Do not feed in autumn or winter — the plant rests and excess nutrients cause root damage.
Watch For
- Root rot — the most common issue; caused by overwatering or poor drainage
- Mealybugs on stems and in leaf axils
- Fungus gnats in consistently moist compost
- Shrivelled leaves indicating underwatering or root damage

☀️ Light
Bright indirect light; tolerates some direct morning sun.
Place near a south- or east-facing window but shield from harsh midday sun, which can scorch the delicate leaves. Insufficient light causes pale, widely-spaced leaves.
💧 Watering
Very infrequent; allow soil to dry out completely between waterings.
The semi-succulent tubers store water, so err on the side of underwatering. In summer water every 2–3 weeks; in winter reduce to once every 4–6 weeks.
🌱 Fertilizing
Monthly with diluted cactus fertiliser, spring and summer only.
Use a half-strength cactus or succulent feed once a month during the growing season. Stop feeding entirely from October to February.
✂️ Pruning
Trim straggly stems to encourage bushier growth.
Cut back any bare or overly long stems just above a leaf node. Cuttings root easily in water or moist compost.
🌿 Humidity
Tolerates normal household humidity; no misting needed.
Average indoor humidity (40–60%) suits this plant well. Avoid placing near radiators which dry the air excessively.
Growing Tips
Let it dry completely
Wait until the soil is bone dry before watering — the semi-succulent tubers along the stems store water and will rot if kept moist.
Bright light for variegation
Place in bright indirect light to maintain the silvery marbling on the leaves. Low light causes the patterning to fade and stems to etiolate.
Propagate in water
Snip a stem with a few leaves and place in a small jar of water — roots form within 2–3 weeks, making this one of the easiest houseplants to propagate.
Feed sparingly
A monthly dose of diluted cactus fertiliser in spring and summer is plenty. Overfeeding produces lush but weak growth.
Pests & Diseases
Pest Mealybugs
Identification: White cottony fluff in leaf axils and along stems; leaves may yellow and drop.
- Dab individual colonies with a cotton swab dipped in rubbing alcohol.
- Spray the whole plant with a diluted neem oil solution weekly until clear.
- Apply a systemic insecticide containing imidacloprid to the compost.
Pest Fungus Gnats
Identification: Tiny black flies hovering around the compost; larvae feed on roots in wet soil.
- Allow soil to dry completely between waterings to break the larval cycle.
- Apply a layer of horticultural grit on the compost surface to deter egg-laying.
- Water with a diluted solution of Bacillus thuringiensis var. israelensis (Gnatrol/Nemasys).
Disease Root Rot Pythium spp. / Phytophthora spp.
Symptoms: Yellowing and mushy stems at the base; shrivelled leaves despite moist soil; plant collapses suddenly.
Treatment: Remove from pot, cut away all blackened roots, dust with sulphur powder, and repot into fresh dry cactus compost. Withhold water for two weeks.
Prevention: Use free-draining cactus compost, a pot with drainage holes, and allow soil to dry completely between waterings.
Disease Powdery Mildew Oidium spp.
Symptoms: White powdery coating on leaf surfaces, typically starting on older leaves.
Treatment: Remove affected leaves, improve air circulation, and spray with a diluted bicarbonate of soda solution.
Prevention: Avoid misting the foliage and ensure good airflow around the plant.
