Aglaonema Rotundum (Round-Leaf Aglaonema) care

Light

The Goldilocks zone. Not the south-facing windowsill (too hot, too direct), not the back of the room (too dim, growth stalls). Prefers medium to bright indirect light to keep the red veining vivid; deep shade dulls the colour. Shield from direct sun, which scorches the dark leaves. Filtered east light is ideal. If you can't decide, a free phone lux-meter app aimed at the leaf at noon should read between 800 and 1,500 lux.

Watering

Watering aglaonema rotundum: when top 2-3 cm of soil is dry, roughly every 5-9 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. Keep the soil lightly and evenly moist but never soggy; this species dislikes drying out fully as much as it dislikes wet feet. Use tepid water and reduce frequency in winter.

Soil and pot

Aglaonema Rotundum grows best in rich, airy, well-draining aroid mix. Use a chunky aroid blend of peat or coir, perlite, orchid bark and a little charcoal. Good aeration is essential, as this temperamental species is sensitive to compacted, waterlogged soil. 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 Rotundum sits happiest at around 60-80% humidity and 20-29°C (68-85°F). A jungle species that needs consistently high humidity; below 50% the leaf edges crisp and brown. A humidifier, terrarium, or grouped plants help maintain the moist air it requires. 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 aglaonema rotundum sparingly. Feed at quarter to half strength with a balanced liquid fertiliser every 3-4 weeks during spring and summer. This species is sensitive to fertiliser salts, so dilute well and rest it in winter. 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 rotundum in the Growli community. Each is annotated with the most common cause so you know where to start.

• Browning, crisping leaf edges — The most common issue: humidity too low for this jungle species. Keep humidity above 60% with a humidifier or enclosed space.
• Faded or greener-than-expected colour — Insufficient light dulls the red veining. Provide brighter indirect light, but never direct sun, to deepen the contrast.
• Root rot — Soggy, compacted soil rots the sensitive roots. Use a chunky aroid mix and water only when the surface begins to dry.
• Cold-induced collapse — More cold-sensitive than hybrid Aglaonemas; chilling below 18°C causes blackened, mushy patches. Keep consistently warm and away from drafts.

Propagation

Propagate by division of the clump at repotting, keeping roots intact on each piece, as this species roots more reluctantly than hybrids. Basal offsets can be separated once well rooted; do so in warm spring conditions. 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 Rotundum is toxic to pets. The ASPCA lists Aglaonema (Chinese evergreen) as toxic to cats and dogs, and this applies to the genus including A. rotundum. It contains insoluble calcium oxalate crystals causing oral burning, drooling, vomiting, and difficulty swallowing if chewed. Keep away from pets. 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.
