More about rotala 'h'ra'

Watering at a glance

Base rhythm	Submerged permanently; 30-50% aquarium water changes weekly
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	Bright indirect light (just back from a sunny window)

About Rotala 'H'ra'

Rotala 'H'ra' · also called Rotala Hira, compact pink Rotala · tropical

A popular aquascaping variety closely related to Rotala rotundifolia, valued for fine leaves that flush bright pink to red and stay compact under strong light. Slightly more demanding than standard rotundifolia for top colour, it is a favourite background and midground plant in high-tech planted tanks for its dense, colourful tops.

Ideal humidity: 100% (submerged aquatic)

The watering schedule, season by season

Rotala 'H'ra' 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 rotala 'h'ra' is submerged permanently; 30-50% aquarium water changes weekly, 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.

Grows underwater in freshwater. Prefers soft to moderately hard water (3-12 dGH), pH 6.0-7.5. Strongest colour and compact growth come with pressurised CO2 (20-30 ppm).

How to tell rotala 'h'ra' needs water

A calendar is the worst way to water rotala 'h'ra'. 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 rotala 'h'ra' for a day is almost always safer than over-watering it.

Overwatering vs underwatering rotala 'h'ra'

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