About Drosera binata 'Multifida Extrema'

Drosera binata 'Multifida Extrema' · also called Multifida Extrema Sundew, Many-forked Sundew · houseplant

Drosera binata 'Multifida Extrema' is a vigorous Australasian fork-leaved sundew whose tall leaves branch repeatedly into many dew-covered points, sometimes dozens per leaf. It is an easy, fast-growing carnivore wanting bright sun, permanently wet mineral-free media and pure water. Given a cool winter rest, it can be grown long-term as a striking, prey-catching specimen.

Ideal humidity: 40-60%

The watering schedule, season by season

Drosera binata 'Multifida Extrema' is a bog plant adapted to nutrient-poor wet ground — it must sit in a tray of pure water and must never get tap water or fertiliser. The base rhythm for drosera binata 'multifida extrema' is keep media constantly wet; stand in 1-2 cm of water via the tray method in growth, drier 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.

Use rain, distilled or RO water only. Keep permanently moist during the growing season; reduce watering during a cool winter rest. Never use tap or mineral water.

What does an overwatered drosera binata 'multifida extrema' look like?

Blackening traps or pitchers from stagnant, warm, mineral-laden water. Rotting crown if kept warm and flooded through winter dormancy. Tap or bottled mineral water kills drosera binata 'multifida extrema'. Its roots cannot handle dissolved minerals — only rain, distilled, or reverse-osmosis water will do.

What are the signs of an underwatered drosera binata 'multifida extrema'?

Traps go limp and brown; pitchers dry up. The medium dries out and the plant collapses quickly.

Can I use tap water on drosera binata 'multifida extrema'?

Only rainwater, distilled or reverse-osmosis water — never tap, mineral or softened water. This is the single most important rule for drosera binata 'multifida extrema'.
