About Bird of paradise

Strelitzia reginae · also called crane flower, Strelitzia · flowering

Bird of paradise is a striking South African banana relative grown for its paddle leaves and crane-shaped orange flowers. Indoors it grows to roughly 1.5-2 m and needs the brightest spot in the house. Mildly toxic to pets.

Strelitzia reginae is endemic to the Eastern Cape and KwaZulu-Natal of South Africa, where it grows in coastal bush, riverbanks and clearings. Its rigid beak-like spathe sits perpendicular to the stem to form a durable perch for the sunbirds that pollinate it.

As a clumping, rhizomatous evergreen from a summer-rainfall region it wants steady moisture through the growing season but tolerates the soil drying somewhat between waterings; ease off in winter to avoid root and rhizome rot.

Ideal humidity: 50-60%

Watch for — Yellow leaves: Overwatering or low light.

The watering schedule, season by season

Bird of paradise 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 bird of paradise is when the top 3 cm of soil is dry, 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.

Soak thoroughly and let excess drain. Reduce watering in winter dormancy.

How to tell bird of paradise needs water

A calendar is the worst way to water bird of paradise. 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 bird of paradise for a day is almost always safer than over-watering it.

Overwatering vs underwatering bird of paradise

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

How often should I water bird of paradise?

Water bird of paradise when the top 3 cm of soil is dry, every 7-10 days. Spring and summer: water when the top of the soil is dry to roughly a knuckle deep — typically every 7-10 days. Winter: water noticeably less — often half as often — because low light and dormancy slow water use right down.
