Watering at a glance

Spring / summer	Spring and summer: water when the top of the soil is dry to roughly a knuckle deep — typically every 5-9 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.

About Anthurium 'Ace of Spades'

Anthurium 'Ace of Spades' · also called Ace of Spades Anthurium · houseplant

Anthurium 'Ace of Spades' is a collector velvet-leaf anthurium grown for its large, heart-shaped, deep emerald-to-near-black leaves with a matte, velvety surface and pale veining. A terrestrial aroid, it is foliage-focused rather than flowering, demanding warmth, high humidity, and a chunky, airy aroid mix to thrive indoors.

Ideal humidity: 60-80%

Watch for — Root rot: A dense or waterlogged mix kills the fleshy roots fast. Use a chunky aroid mix and let the top layer dry between waterings.

The watering schedule, season by season

Anthurium 'Ace of Spades' 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 anthurium 'ace of spades' is when the top 3-4 cm of the mix is dry, roughly every 5-9 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 5-9 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 layer dry before repeating. The chunky mix should never stay sodden; consistent slight moisture suits it best. Use room-temperature water and avoid letting the pot sit in runoff, as the fleshy roots rot easily.

How to tell anthurium 'ace of spades' needs water

A calendar is the worst way to water anthurium 'ace of spades'. 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 anthurium 'ace of spades' for a day is almost always safer than over-watering it.

Overwatering vs underwatering anthurium 'ace of spades'

The two failure modes can look alike at a glance, so check the soil weight and wetness before you decide. For anthurium 'ace of spades' 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 anthurium 'ace of spades' 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 anthurium 'ace of spades'. 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 anthurium 'ace of spades', 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 anthurium 'ace of spades'.
