Care at a glance

Light

Aglaonema Chocolate wants the spot a few feet back from a sunny window — bright enough to read a paperback at noon, but the sun never falls directly on the leaves. The dark foliage tolerates low to medium indirect light better than pale cultivars, though bright indirect light deepens the burgundy underside. Keep out of direct sun, which can scorch and dull the leaves. A faint hand shadow at midday is the right amount; a sharp dark shadow means it's getting direct sun and probably too much.

Watering

Water aglaonema chocolate when the top 2-3 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, then let the surface dry before watering again. Keep evenly moist in summer and drier in winter; avoid waterlogged soil, which rots the roots and stems.

Soil and pot

Aglaonema Chocolate grows best in well-draining, peat- or coir-based potting mix. Use a light, airy houseplant mix with perlite or bark for drainage. A slightly acidic to neutral pH suits it best, and the pot must have drainage holes. 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 Chocolate sits happiest at around 50-60% humidity and 18-27°C (65-80°F). Prefers moderate to high humidity but tolerates average indoor air. Dry winter conditions can brown leaf tips, so a pebble tray or humidifier helps maintain healthy foliage. 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 chocolate sparingly. Feed monthly in spring and summer with a balanced, half-strength liquid houseplant fertiliser. Stop feeding in autumn and winter while growth slows to avoid salt build-up and fertiliser burn. 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 chocolate in the Growli community. Each is annotated with the most common cause so you know where to start.

  • Dull, greying leavesToo little light can flatten the dark colour. Provide bright indirect light to deepen the burgundy and pink tones.
  • Yellowing leavesUsually overwatering or cold stress. Let the soil dry between waterings and keep above 16°C, away from drafts.
  • Brown leaf tipsDry air or tap-water salts. Raise humidity and water with filtered or rainwater.
  • Spider mitesDry indoor air encourages mites, seen as fine webbing and speckled leaves. Increase humidity and rinse or treat the foliage.

Propagation

Propagate by dividing established clumps at repotting, or by rooting node-bearing stem cuttings in water or moist mix. Warm spring conditions give the best success. 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 Chocolate is toxic to pets. The ASPCA lists Aglaonema (Chinese evergreen) as toxic to cats and dogs. It contains insoluble calcium oxalate crystals that cause oral irritation, intense burning of the mouth and lips, drooling, vomiting and difficulty swallowing. Keep 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.

Aglaonema Chocolate care — frequently asked questions

What is the common name for Aglaonema 'Chocolate'?

Aglaonema 'Chocolate' is most commonly called Aglaonema Chocolate, but it is also known as Chocolate Aglaonema, Chocolate Chinese Evergreen. The names refer to the same species, so care instructions for Aglaonema Chocolate apply identically to anything sold as Chocolate Aglaonema.

How much light does aglaonema chocolate need?

Aglaonema Chocolate grows best in medium indirect light (a couple of metres from a window). The dark foliage tolerates low to medium indirect light better than pale cultivars, though bright indirect light deepens the burgundy underside. Keep out of direct sun, which can scorch and dull the leaves.

How often should I water aglaonema chocolate?

Water aglaonema chocolate when the top 2-3 cm of soil is dry, roughly every 7-10 days. Water thoroughly, then let the surface dry before watering again. Keep evenly moist in summer and drier in winter; avoid waterlogged soil, which rots the roots and stems. The finger-test (or lifting the pot to feel its weight) beats a fixed weekly calendar because pot size, light, and season all change how fast the soil dries.

Is aglaonema chocolate toxic to cats and dogs?

Aglaonema Chocolate is toxic to pets. The ASPCA lists Aglaonema (Chinese evergreen) as toxic to cats and dogs. It contains insoluble calcium oxalate crystals that cause oral irritation, intense burning of the mouth and lips, drooling, vomiting and difficulty swallowing. Keep away from pets and children.

What USDA hardiness zone does aglaonema chocolate grow in?
