Indoor Very easy ⚠ Toxic to pets

Chinese Evergreen

Aglaonema · Chinese evergreen

Broad, patterned leaves in silver, cream, green — and, in newer kinds, startling pinks and reds. One of the best-looking plants that genuinely tolerates a shady room, as long as you keep it warm.

Difficulty 2 / 5 — easy-going

Mildly toxic to cats, dogs & people if chewed

An aroid — the leaves contain insoluble calcium oxalate crystals, so chewing causes mouth and throat irritation, drooling and sometimes vomiting. Mild and self-limiting, but keep it away from pets and toddlers that nibble. Source: ASPCA.

Care at a glance

Everything that matters, in six lines. The detail is further down.

Light

Low to medium, indirect

Dark-green kinds take low light well; pink and heavily variegated ones need brighter (indirect) light for colour.

Water

When the top dries

Moderate and even. Let the surface dry between drinks; don’t keep it soggy.

Temperature

18–27 °C · min 15 °C

Warmth-loving. Cold and draughts are its real enemy — chilling damages the leaves.

Humidity

Average to high

Tolerates normal rooms; brown tips can mean the air is very dry.

Feeding

Monthly in growth

A weak feed spring to summer keeps the leaves coming.

Soil

Free-draining peat-free

Good peat-free houseplant compost with a little drainage.

The almanac · Chinese Evergreen through the year

What to do, and when

Spring

Growth resumes. Repot if congested and resume feeding as warmth returns.

Summer

Main growth. Water when the top dries and feed monthly.

Autumn

Ease off water and feed; watch for cold as the nights draw in.

Winter

Its vulnerable season — keep it warm (above 15 °C), away from draughts, and only lightly moist.

Colour in a shady room

Aglaonema is one of the few genuinely handsome plants that will take a low-light spot — the classic silver-and-green kinds positively prefer shade to strong sun. The vivid pink and red cultivars are the exception: they need decent (indirect) light to keep their colour, and fade to green in gloom.

Match the plant to the spot and it’s close to foolproof — no fussing over light for the green sorts, a brighter shelf for the colourful ones.

Quick tell: pale, mushy patches after a cold snap are chill damage, not disease. Keep it above 15 °C and well away from draughty doors and windows.

Warmth is the one rule

If a peace lily is dramatic about water, an aglaonema is dramatic about cold. It hails from tropical forest floors and resents temperatures below about 15 °C, cold windowsills, and draughts — all of which show up as blotchy, greyish damage.

Keep it warm and evenly (not heavily) watered and it will reward you for years with very little effort.

Common problems

Yellowing leaves

Overwatering or cold. Ease off water; move it somewhere warmer.

Brown leaf tips

Dry air or tap-water salts. Raise humidity; try rainwater.

Greyish, mushy patches

Cold damage. Keep it above 15 °C and out of draughts.

Faded colour

Coloured kinds are too dark. Give more indirect light.
