Arrowhead vine (arrowhead plant)
Syngonium podophyllum
Evergreen tropical aroid vine with arrowhead-shaped leaves; popular, easy houseplant with many variegated cultivars and climbing habit.
Caution: Toxic to Pets
Toxicity: toxic
Contains insoluble calcium oxalate crystals; ingestion causes oral irritation, drooling, vomiting and swelling in pets and humans. Keep out of reach.
🌱Care Requirements
Light
Place the Arrowhead vine in bright, indirect light near an east- or north-facing window or a few metres back from a west/south window. Avoid harsh direct sun which scorches leaves; it tolerates lower light but will become leggy and lose variegation.
Water
Water when the top 2–3 cm (0.8–1.2 in) of potting mix has dried. Water thoroughly until excess drains, then discard drainage. Reduce frequency in winter. Avoid constant soggy soil to prevent root rot; use a well-draining mix.
Humidity
Prefers moderate to high humidity (40–70%). Increase humidity with a pebble tray, regular misting, grouping plants, or a humidifier. Avoid prolonged dry air from heaters or AC vents which cause brown edges.
Temperature
Ideal 18–24°C (65–75°F); acceptable range 15–29°C (59–84°F). Avoid exposure below 12–13°C (54–55°F) and sudden temperature swings or cold drafts.
🔧Common Problems & Solutions
Yellowing lower leaves
Cause: Overwatering or poor drainage causing root stress
Solution: Check roots, repot into fresh, airy mix if needed, reduce watering frequency and ensure pot drains well
Brown crispy leaf edges
Cause: Low humidity, underwatering, or salt build-up from fertilizers
Solution: Increase humidity, water more consistently, flush soil occasionally to remove salts and trim damaged tissue
Leggy, sparse growth with small leaves
Cause: Insufficient light
Solution: Move to brighter indirect light, prune to encourage bushiness, and consider training to a stake or moss pole
Sticky residue, webbing or small white cottony spots
Cause: Pests such as aphids, mealybugs or spider mites
Solution: Isolate plant, wipe leaves, treat with insecticidal soap or neem oil, repeat treatments until pests are gone
✂️How to Propagate Arrowhead vine (arrowhead plant)
Take 10–15 cm stem cuttings with at least one node and a couple of leaves. Root in water or directly into moist, well-draining potting mix. Keep warm and bright, out of direct sun. Change water every few days if rooting in water; transplant when roots are 2–3 cm long. For division, remove plant from pot and separate rooted sections, then pot individually.
🌍Origin & Background
Family: Araceae
Native to: Tropical Central and South America, from Mexico through rainforest regions to Brazil and the Guianas.
Natural Habitat: Grows as an understory vine in moist, shaded tropical forests, often climbing trees or trailing over leaf litter in warm, humid, dappled-light conditions with rich organic soil.
🗓Seasonal Care Guide
Winter
Reduce watering and stop fertilizing. Keep plant in bright, stable indoor temperatures and maintain humidity. Avoid placing near cold drafts or heating vents.
Spring
Resume regular fertilizing with a balanced dilute feed, repot if rootbound, and take cuttings for propagation. Increase watering as growth resumes.
Summer
Provide bright, indirect light and higher humidity. Water more frequently during active growth but maintain good drainage to prevent root rot.
Fall
Gradually reduce watering and stop heavy feeding as growth slows. Prune back leggy growth and check for pests before bringing plant indoors.
❓Frequently Asked Questions
How often should I water my Arrowhead plant?
Water when the top 2–3 cm of soil is dry, typically every 7–14 days depending on light and temperature.
Is Syngonium toxic to cats and dogs?
Yes. It contains calcium oxalate crystals that cause oral irritation, drooling and vomiting if chewed or eaten.
Can I grow Arrowhead vine in low light?
It tolerates low light but growth will slow, leaves may lose variegation, and the plant can become leggy; brighter indirect light is better.
How do I encourage bushier growth?
Pinch or prune growing tips regularly, provide bright indirect light, and propagate cuttings to create fuller plants.
Should I mist my Arrowhead plant?
Misting can help short-term but use a humidifier, pebble tray, or grouping for more consistent humidity benefits.
