Care at a glance

Light

Aglaonema 'Lady Valentine' is what florists mean by "bright spot, no direct sun" — close enough to a south or east window to feel the brightness, with a sheer curtain or a few feet of distance keeping the sun off the leaves. Wants bright, indirect light to maintain its strong pink pigment; low light dulls the colour and weakens growth. Avoid direct sun, which bleaches and scorches the delicate pink areas. A phone lux-meter at the leaf surface should read 1,500-3,000 lux at noon.

Watering

Water aglaonema 'lady valentine' when the top 3-4 cm of soil is dry, roughly every 7-10 days. The actual day count varies with pot size, light, and season — the finger test (or lifting the pot to feel its weight) is more reliable than a fixed calendar. Empty any drainage saucer afterwards so the pot isn't sitting in water. Water thoroughly and let the upper third dry before the next drink. The heavily variegated leaves photosynthesise less, so growth and water use are slow; avoid keeping it soggy.

Soil and pot

Aglaonema 'Lady Valentine' grows best in loose, well-draining peat- or coir-based mix. An airy blend of peat or coir, perlite and bark at pH 5.6-6.5 suits it best. Always use a pot with drainage holes to keep the roots and stems from rotting. 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 'Lady Valentine' sits happiest at around 50-65% humidity and 18-27°C (65-80°F). Prefers moderate to higher humidity above 50% for the best leaf condition; the pink areas brown easily in dry air. A pebble tray, humidifier or grouping helps in heated rooms. 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 'lady valentine' sparingly. Feed monthly in spring and summer with a balanced half-strength liquid houseplant fertiliser. Stop in autumn and winter. Because the pink foliage is sensitive, avoid overfeeding, which browns the leaf margins and pink patches. 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 'lady valentine' in the Growli community. Each is annotated with the most common cause so you know where to start.

  • Pink fading to greenToo little light is the cause. Increase bright indirect light to keep the candy-pink colouring strong.
  • Brown patches on pink areasThe pink tissue is sensitive to dry air, sun and salts. Raise humidity, diffuse light and use filtered water.
  • Stem and root rotFrom overwatering this slow-growing plant. Let the top third dry fully and ensure free drainage.
  • Cold-damage blotchesBelow 15°C dark greasy spots appear and leaves drop; keep warm and away from cold windows.

Propagation

Propagate by dividing the clump at repotting or by rooting stem cuttings with several nodes in water or moist mix. Highly variegated cuttings root more slowly, so keep them warm and humid. 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 'Lady Valentine' is toxic to pets. Aglaonema (Chinese Evergreen) is listed by the ASPCA as toxic to cats and dogs. The insoluble calcium oxalate crystals cause oral irritation, burning of the mouth and lips, excessive drooling, vomiting and difficulty swallowing when chewed. Keep out of reach of 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.
