Watering at a glance

Base rhythm	When the top 2-3cm of soil is dry (roughly weekly in summer, less in winter)
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 Begonia 'Maori Haze'

Begonia rex 'Maori Haze' · also called Maori Haze Begonia, Rex Begonia 'Maori Haze' · houseplant

Begonia 'Maori Haze' is a rhizomatous Rex begonia grown for silvery, pewter-purple, pointed foliage. It thrives in bright indirect light, high humidity above 50%, and evenly moist but well-drained soil. Compact at 10-50cm tall, it suits warm, sheltered indoor spots. Toxic to cats and dogs per the ASPCA, so keep it out of reach.

Ideal humidity: 50-70%

Watch for — Crispy brown leaf edges: Almost always a sign of air that is too dry. Raise humidity above 50% with a pebble tray or by grouping plants; keep away from radiators and cold draughts.

The watering schedule, season by season

Begonia 'Maori Haze' 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 begonia 'maori haze' is when the top 2-3cm of soil is dry (roughly weekly in summer, less in winter), 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 2-3cm of compost feels dry, watering from below or at the soil line so foliage stays dry. Keep evenly moist but never waterlogged in spring and summer, then ease off in winter as growth slows. Soggy soil and wet leaves invite root rot and powdery mildew.

How to tell begonia 'maori haze' needs water

A calendar is the worst way to water begonia 'maori haze'. 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 begonia 'maori haze' for a day is almost always safer than over-watering it.

Overwatering vs underwatering begonia 'maori haze'

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