Aglaonema White Rajah (White Rajah Chinese Evergreen) care

Light

Bright but filtered. Aglaonema White Rajah burns within days in unfiltered south-facing summer sun, and stops growing within months in deep shade. Its heavily white-variegated leaves have less chlorophyll, so it needs brighter indirect light than green aglaonemas to stay vigorous. Medium light is tolerated but slows growth. Avoid direct sun, which scorches the pale tissue and bleaches the variegation further. 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 aglaonema white rajah: when the top 3-5 cm of soil is dry, roughly every 7-12 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. Water thoroughly, then let the top third of the pot dry before watering again. Aglaonemas store water and are prone to root rot if kept soggy, so err on the drier side. Water less in winter and ensure the pot drains freely.

Soil and pot

Aglaonema White Rajah grows best in well-draining, peat-based potting mix. Use a light, airy houseplant mix with added perlite, bark or coarse sand for drainage. A blend of quality potting soil with perlite works well. Slightly acidic to neutral pH suits it; avoid dense, water-retentive soils that stay wet. 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

Aglaonema White Rajah sits happiest at around 50-70% humidity and 18-27°C (65-80°F). Prefers moderate to high humidity for the best leaf finish, but tolerates average indoor levels. Very dry air can cause brown tips. A pebble tray or occasional grouping helps; it is more forgiving of dry rooms than most variegated tropicals. 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 aglaonema white rajah sparingly. Feed every 4-6 weeks in spring and summer with a balanced houseplant fertiliser at half strength. Aglaonemas are light feeders; over-fertilising causes leaf-tip burn. Flush the soil occasionally to clear salts and stop feeding during the winter slowdown. 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 aglaonema white rajah in the Growli community. Each is annotated with the most common cause so you know where to start.

• Brown leaf tips — Usually low humidity, fluoride and salt buildup, or over-fertilising. Use rain or filtered water, feed lightly and raise humidity to keep the pale leaf tips clean.
• Yellowing leaves — Most often overwatering and soggy soil. Let the top third of the pot dry between waterings and confirm drainage; chronically wet roots quickly fail.
• Loss of variegation — Too little light pushes the plant to revert toward greener growth. Provide bright indirect light to maintain the bright white-and-green patterning.
• Cold damage — Greyish, water-soaked blotches appear below about 15°C. Keep it warm, away from cold windows, drafts and air-conditioning vents, which it strongly dislikes.

Propagation

Propagate by division of basal clumps or rooted suckers when repotting, ensuring each piece has roots and growth points. Stem cuttings with a few nodes can be rooted in water or a light, moist mix in warmth. Air layering also works for older, leggy stems. 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

Aglaonema White Rajah is toxic to pets. The ASPCA lists Aglaonema (Chinese evergreen) as toxic to cats and dogs. It contains insoluble calcium oxalate crystals; chewing causes oral irritation, intense burning of the mouth, lips and tongue, drooling, vomiting and difficulty swallowing. Keep this plant away from pets and children. 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.
