Watering at a glance

Base rhythm	When the top 3-4 cm of soil is dry, roughly every 7-10 days
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 'First Diamond'

Aglaonema commutatum 'First Diamond' · also called First Diamond Chinese Evergreen · houseplant

Aglaonema 'First Diamond' is a compact Chinese Evergreen with near-white, silvery leaves edged and flecked in green. It thrives in low-to-medium light, tolerates neglect, and is among the easiest variegated aroids. The pale foliage burns in direct sun, so keep it shaded. Warm, draught-free rooms with steady moisture keep its bright colouring crisp.

Ideal humidity: 50-60%

Watch for — Brown leaf tips: Usually from dry air, fluoride or salt build-up in tap water. Raise humidity and flush the pot occasionally.

The watering schedule, season by season

Aglaonema 'First Diamond' 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 'first diamond' is when the top 3-4 cm of soil is dry, roughly every 7-10 days, 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.

Water thoroughly until it drains, then let the upper third of the pot dry before the next drink. Cut back in winter. Soggy, cold soil causes stem and root rot faster than underwatering.

How to tell aglaonema 'first diamond' needs water

A calendar is the worst way to water aglaonema 'first diamond'. 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 'first diamond' for a day is almost always safer than over-watering it.

Overwatering vs underwatering aglaonema 'first diamond'

The two failure modes can look alike at a glance, so check the soil weight and wetness before you decide. For aglaonema 'first diamond' 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 'first diamond' 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 'first diamond'. 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 'first diamond', 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 'first diamond'.
