Watering at a glance

Base rhythm	Submerged aquatic — routine 20-30% weekly water changes are recommended.
Spring / summer	Spring and summer: water when the top of the soil is dry to roughly a knuckle deep — typically when the soil tells you it is time.
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	Low light (north window or shaded room)

About Coffee-leaf Anubias

Anubias coffeifolia · also called Coffee Anubias, Coffeifolia Anubias · tropical

A distinctive cultivar or variety of Anubias producing deeply corrugated, dark green leaves that strikingly resemble coffee plant foliage. It is highly popular in planted aquariums for its unusual leaf texture and slow, hardy growth. Like all Anubias, it thrives when the rhizome is attached to hardscape rather than buried in substrate. As an aroid it contains calcium oxalates and is toxic to pets.

Ideal humidity: N/A (submerged aquatic)

Watch for — Yellow leaves: Indicates iron or micronutrient deficiency. Dose a liquid fertiliser containing chelated iron.

The watering schedule, season by season

Coffee-leaf Anubias 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 coffee-leaf anubias is submerged aquatic — routine 20-30% weekly water changes are recommended., 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 when the soil tells you it is time.
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.

Tolerates a wide range of water parameters. Soft to moderately hard water at pH 6.0-8.0 is acceptable. Stable conditions prevent leaf melt and algae build-up.

How to tell coffee-leaf anubias needs water

A calendar is the worst way to water coffee-leaf anubias. 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 coffee-leaf anubias for a day is almost always safer than over-watering it.

Overwatering vs underwatering coffee-leaf anubias

The two failure modes can look alike at a glance, so check the soil weight and wetness before you decide. For coffee-leaf anubias 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 coffee-leaf anubias 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 coffee-leaf anubias. 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 coffee-leaf anubias, the levers that matter most are:

In the low light this plant tolerates, the soil dries slowly — wait noticeably longer between waterings than the figures suggest.
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 coffee-leaf anubias.
