Watering at a glance

Base rhythm	When the top 2-3 cm (1 inch) of compost is dry, roughly every 7-10 days in growth
Spring / summer	Spring and summer: water when the top of the soil is dry to roughly a knuckle deep — typically every 7-10 days.
Autumn	Autumn: growth slows, so stretch the interval and let it dry a little more between waterings.
Winter	Winter: water noticeably less — often half as often — because low light and dormancy slow water use right down.
Light	Medium indirect light (a couple of metres from a window)

About Aglaonema (Chinese Evergreen)

Aglaonema commutatum · also called Chinese evergreen, Aglaonema · houseplant

Aglaonema commutatum, or Chinese evergreen, is a slow-growing tropical foliage plant from the Philippines prized for its silver-marbled leaves and forgiving nature. Its one defining need is warmth: it suffers chilling injury below roughly 15C, so keep it out of cold draughts and unheated rooms while giving it steady, indirect light.

Ideal humidity: 40-60%

Watch for — Chilling injury from cold: The single biggest killer. Exposure to temperatures roughly between freezing and 15C (59F) causes grey-green blotches that yellow, plus drooping and rot. Keep above 15C and away from draughty doors, cold windows and air-con vents.

The watering schedule, season by season

Aglaonema (Chinese Evergreen) likes a soak-then-partly-dry rhythm — let the top of the soil dry before watering again, and never leave it standing in water. The base rhythm for aglaonema (chinese evergreen) is when the top 2-3 cm (1 inch) of compost is dry, roughly every 7-10 days in growth, but the real interval moves with the season, the light and the pot — so treat the figures below as a starting point and always confirm with the plant itself.

Spring & summer (active growth): Spring and summer: water when the top of the soil is dry to roughly a knuckle deep — typically every 7-10 days.
Autumn (slowing down): Autumn: growth slows, so stretch the interval and let it dry a little more between waterings.
Winter (rest / dormancy): Winter: water noticeably less — often half as often — because low light and dormancy slow water use right down.

Keep the compost lightly and evenly moist from spring to autumn, letting the top 2-3 cm dry between waterings, then water sparingly through winter. It tolerates short dry spells far better than soggy roots, so err on the dry side. Use room-temperature water and never let the pot stand in water, as constant wet causes root rot.

How to tell aglaonema (chinese evergreen) needs water

A calendar is the worst way to water aglaonema (chinese evergreen). Check the plant and the soil instead — for this species, look for these signals in order:

The top 2-3 cm of soil is dry to the touch (or a knuckle-deep finger test comes back dry).
Lifting the pot, it feels distinctly light.
Leaves droop slightly or lose a little of their gloss just before they truly need water.

The most reliable single check is the first one on that list. When two signals agree, water; when they disagree, wait a day and look again — under-watering aglaonema (chinese evergreen) for a day is almost always safer than over-watering it.

Overwatering vs underwatering aglaonema (chinese evergreen)

The two failure modes can look alike at a glance, so check the soil weight and wetness before you decide. For aglaonema (chinese evergreen) specifically:

Signs you are overwatering

Yellowing lower leaves and a pot that stays wet and heavy for days.
Soft, brown, mushy stems or a sour soil smell — root rot.
Fungus gnats breeding in permanently damp soil.

Signs you are underwatering

Drooping, curling leaves with crispy brown edges that perk up after watering.
The rootball shrinks away from the pot and water runs straight down the sides.
Slow growth and a generally tired, washed-out look.

Watering aglaonema (chinese evergreen) on a fixed weekly calendar regardless of season is the most common mistake — in dim winter light the same routine drowns it. Check the soil, not the date.

Water quality notes

Tap water is generally fine for aglaonema (chinese evergreen). If your water is very hard and you see brown leaf tips, switch to filtered or rainwater.

Seasonal and environmental adjusters

Every figure above shifts with the conditions in your home. For aglaonema (chinese evergreen), the levers that matter most are:

More light and warmth speed drying; the brighter the spot, the shorter the real interval.
Pot size and material matter — small terracotta pots dry far faster than large glazed or plastic ones.
Lifting the pot to feel its weight is more reliable than any calendar for judging when to water.

Pot choice is part of this too — work out the right size with the pot size calculator, since a pot that is too big stays wet long enough to rot the roots of aglaonema (chinese evergreen).
