Pandan (Screwpine) care

Light

Bright but filtered. Pandan burns within days in unfiltered south-facing summer sun, and stops growing within months in deep shade. Thrives in bright indirect to lightly filtered light; some gentle direct sun boosts fragrance and colour. Harsh, hot midday sun can scorch leaves. Indoors, a bright window with sheer-filtered sun is ideal. 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 pandan: when the top 2-3 cm of soil is dry, roughly every 4-7 days. 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. Likes evenly moist soil and resents drying out fully, but also dislikes standing water. Water when the surface starts to dry, easing off in cooler months. Use tepid water and ensure pots drain freely.

Soil and pot

Pandan grows best in rich, moisture-retentive, well-drained mix. Wants fertile, humus-rich soil that stays moist yet drains well, slightly acidic to neutral. A loam-based mix amended with compost and perlite gives both moisture retention and the drainage the roots need. 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

Pandan sits happiest at around 60-80% humidity and 20-32°C (68-90°F). A humidity lover from tropical lowlands. Dry indoor air browns and splits the leaf tips. Boost humidity with pebble trays, grouping or a humidifier, particularly in heated rooms during winter. If you keep the room above 20 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 pandan sparingly. Feed every 2-4 weeks in spring and summer with a balanced liquid fertiliser at moderate strength to support the leafy growth. Reduce or stop feeding in winter when growth slows. Avoid overfeeding salts in containers. 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 pandan in the Growli community. Each is annotated with the most common cause so you know where to start.

• Brown leaf tips from dry air — Low humidity browns and crisps the strap-leaf tips. Raise humidity and keep soil evenly moist to keep leaves lush and fragrant.
• Cold sensitivity — It suffers and may drop leaves below about 12-15°C. Keep it warm year-round and never expose it to frost or cold drafts.
• Root rot from overwatering — Soggy, poorly drained soil rots the roots. Use a free-draining mix and let the surface dry slightly between waterings.
• Pale, sparse growth in low light — Too little light yields weak, faded leaves with little fragrance. Move to brighter filtered light to restore vigour and aroma.

Propagation

Propagated mainly by separating basal offsets (pups) once they have their own roots, since cultivated pandan almost never sets seed. Plantlets forming on aerial prop roots can also be detached and potted up. 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

Pandan is mildly toxic to pets. Pandanus amaryllifolius is not individually listed on the ASPCA Toxic and Non-Toxic Plant database. Pandanus leaves can contain irritant calcium oxalate crystals and a swallowed whole leaf could pose a choking or obstruction hazard. Treat with caution, keep pets from chewing the foliage, and verify with a vet if ingestion occurs. 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.
