Rhaphidophora korthalsii (Shingle Plant) care

Light

Bright but filtered. Rhaphidophora korthalsii burns within days in unfiltered south-facing summer sun, and stops growing within months in deep shade. Grows best in medium to bright indirect light, which keeps shingling tight and growth steady. It tolerates lower light but shingles less neatly and grows slowly; avoid direct sun, which scorches the appressed juvenile leaves. If you only have a south window, set the plant back 1.5 m or hang a sheer curtain — both knock the intensity down into the right range.

Watering

Watering rhaphidophora korthalsii: when the top 2-3 cm of soil is dry, roughly every 5-8 days in growth. The number that matters isn't the day of the week — it's how dry the top 2-3 cm of the pot feels. A finger in the soil tells you more than a watering app. After every watering, tip the saucer. Water once the top 2-3 cm of mix dries, keeping it evenly moist but never waterlogged in active growth. Keep the moss support damp to encourage aerial roots to grip. Reduce watering in winter.

Soil and pot

Rhaphidophora korthalsii grows best in chunky, well-draining aroid mix. A coarse blend of bark, perlite, coir and charcoal provides the aeration and drainage its aerial-rooting habit needs. It must drain freely to avoid root rot. Slightly acidic pH (5.5-6.5) suits it. A pot with a working drainage hole is non-negotiable for this species — even free-draining mix will turn soggy in a closed planter. If you love the look of a decorative pot without a hole, use it as a cachepot around an inner nursery pot you can lift out to water.

Humidity and temperature

Rhaphidophora korthalsii sits happiest at around 60-80% humidity and 18-29°C (65-84°F). Requires high humidity; a minimum of around 60%, ideally 60-80%, is needed for tight shingling and to keep juvenile leaves flat and unblemished. It languishes in dry household air, so a humidifier, cabinet or grouped planting is strongly advised. If you keep the room above 18 year-round and avoid placing the plant near a cold draught, a hot radiator, or an air-conditioning vent, you have already handled the two biggest indoor stressors.

Fertilising

Feed rhaphidophora korthalsii sparingly. Feed every 2-4 weeks in spring and summer with a balanced liquid fertiliser at half strength to fuel its climbing growth. Reduce or stop in autumn and winter. Consistent feeding while it climbs helps drive the transition to larger adult leaves. Skip fertiliser entirely on a stressed, recently-repotted, or actively wilting plant — fertiliser salts make damage worse, not better. Wait for a round of healthy new growth before resuming a feeding rhythm.

Common problems

Below are the issues we see most often on rhaphidophora korthalsii in the Growli community. Each is annotated with the most common cause so you know where to start.

• Leaves not shingling tightly — Loose, lifting juvenile leaves usually mean low humidity or weak light. Raise humidity above 60% and provide a damp moss support in brighter indirect light.
• Failure to climb or grip — Without a textured, moist support the aerial roots cannot attach. Give it a moss pole or slab kept damp so roots can grab on.
• Brown, crispy juvenile leaves — Dry air scorches the flat leaves. Increase humidity and keep the substrate evenly moist.
• Root rot — Dense, soggy soil suffocates the roots. Use a chunky, fast-draining aroid mix and water only when the surface starts to dry.

Propagation

Propagate from stem cuttings containing a node and an aerial root; press onto damp sphagnum or a moss board, or root in a humid, airy mix. Keep warm and very humid; rooting and re-shingling take several weeks. Propagation is the cheapest, most satisfying way to expand a collection — and it doubles as insurance against losing a mature plant to an accident. Take a backup cutting once the parent is established and healthy.

Toxicity to pets

Rhaphidophora korthalsii is toxic to pets. Toxic to cats and dogs. The ASPCA classifies aroid genera in the Araceae, including Rhaphidophora, as toxic; all parts contain insoluble calcium oxalate raphides. Chewing causes oral pain, swelling, drooling, pawing at the mouth, vomiting and difficulty swallowing, and the sap can irritate skin. If you keep cats, dogs, or curious children in the house, weigh placement carefully — a high shelf or a hanging planter is enough for casual safety. For severe ingestion incidents, call your local vet and the ASPCA Animal Poison Control Center (in the US, 888-426-4435).

Pet-safety status is sourced from the ASPCA Toxic and Non-Toxic Plant List, which catalogues the most-asked-about plants for cats, dogs, and horses.
