Watering at a glance

Base rhythm	Moderate during growing season; withhold in dormancy
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	Medium indirect light (a couple of metres from a window)

About Roxburgh's Typhonium

Typhonium roxburghii · also called Roxburgh's Typhonium, Dwarf Voodoo Lily · tropical

Roxburgh's Typhonium is a diminutive Asian aroid reaching only 10–15 cm, producing small glossy triangular leaves and velvety deep maroon spathes repeatedly through summer. Best grown in containers in a sheltered semi-shaded spot, it requires a warm, frost-free dormancy in winter. A curious collector's plant with a brief, pungent floral scent that attracts pollinators.

Ideal humidity: 50–70%

Watch for — Tuber rot from overwatering: The most common problem, especially in winter. The small tubers desiccate less easily than they rot. Keep dormant tubers almost completely dry in frost-free conditions. During the growing season, allow the compost surface to dry slightly between waterings.

The watering schedule, season by season

Roxburgh's Typhonium 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 roxburgh's typhonium is moderate during growing season; withhold in dormancy, 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.

Water when the top centimetre of compost feels dry during the growing season. The small tubers are highly prone to rot if overwatered. Keep virtually dry during winter dormancy; store the tubers in their pots or in dry vermiculite above 5°C.

How to tell roxburgh's typhonium needs water

A calendar is the worst way to water roxburgh's typhonium. 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 roxburgh's typhonium for a day is almost always safer than over-watering it.

Overwatering vs underwatering roxburgh's typhonium

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