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.

Mature size: Leaves to 20-30 cm tall with many forked points; clumps spread to 20 cm or more across.

Watch for — Loss of dew: Low light, low humidity or disturbance. Brighten the light and keep roots wet; dew usually returns quickly.

How to tell drosera binata 'multifida extrema' needs repotting

Repotting on a calendar is less reliable than reading the plant. For drosera binata 'multifida extrema', watch for these signs:

Roots poking out of the drainage holes or coiling visibly around the inside of the pot.
You are watering far more often than you used to because the rootball dries out within a day or two.
Water runs straight through and out the bottom without soaking in.
Top growth has slowed or new drosera binata 'multifida extrema' leaves are noticeably smaller than older ones despite good light.

How often to repot drosera binata 'multifida extrema'

Every 12–18 months — sooner if roots show fast. Drosera binata 'Multifida Extrema''s growth habit — vigorous, tall fork-leaved sundew forming clumps; each leaf branches repeatedly into numerous dew-tipped points held on long petioles. spreads readily by underground roots and can form dense colonies. — sets the pace. 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.

What size pot to step drosera binata 'multifida extrema' up to

Step up one pot size — about 2–3 cm (an inch) wider. Drosera binata 'Multifida Extrema' grows fast, so it will fill that space within a season, but jumping several sizes at once still backfires: the unused soil stays soggy and rots even a vigorous root system. One size at a time, every year or so, is the rhythm.

Not sure of the exact diameter? Our pot size calculator takes the current pot and root spread and tells you the right next size — it deliberately recommends a single step up, never a big jump.

The best time of year to repot drosera binata 'multifida extrema'

Early spring, just as new growth restarts, is the ideal window for drosera binata 'multifida extrema'. The plant is moving into its strongest growth phase and re-roots into fresh soil quickly. Avoid repotting in winter dormancy or, for flowering plants, while it is in bud or bloom — recovery is slowest then and you risk dropping the flowers.

Step-by-step: repotting drosera binata 'multifida extrema'

Time it for spring. Repot drosera binata 'multifida extrema' in early spring as growth restarts so it re-roots quickly into the fresh soil.
Choose one size up. Pick a pot about 2–3 cm wider with drainage holes. One step only — a much bigger pot stays soggy and rots roots.
Ease the plant out. Water lightly the day before, then tip drosera binata 'multifida extrema' out and gently loosen any roots circling the bottom of the rootball.
Repot at the same depth. Put a layer of fresh nutrient-free carnivorous mix in the new pot, set the plant so its soil line is unchanged, and backfill, firming lightly.
Water and pause feeding. Water once to settle the soil. Hold off fertiliser for about a month — fresh mix already has nutrients and feeding now burns new roots.

Aftercare

Water drosera binata 'multifida extrema' once to settle the soil, then let the surface dry before watering again — fresh mix around the roots stays wetter than the old compacted ball, so the commonest post-repot mistake is overwatering. Keep it out of direct sun for a week or two while roots re-establish. Do not fertilise for about 4 weeks — fresh mix already carries nutrients and feeding freshly disturbed roots scorches them.

The right soil mix for drosera binata 'multifida extrema'

Drosera binata 'Multifida Extrema' wants nutrient-free carnivorous mix. 1:1 sphagnum peat and washed silica sand or perlite. Standard composts and fertilisers will kill it; only mineral-free media is safe. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting drosera binata 'multifida extrema' — frequently asked questions

How often should you repot drosera binata 'multifida extrema'?

Every 12–18 months — sooner if roots show fast for drosera binata 'multifida extrema'. Repot drosera binata 'multifida extrema' roughly every 12–18 months, in early spring as growth restarts. It grows fast and circles its pot quickly, so step up one size (about 2–3 cm wider) into fresh nutrient-free carnivorous mix. Don't jump several sizes — that soggy excess soil is what rots vigorous roots.

What size pot does drosera binata 'multifida extrema' need?

When is the best time of year to repot drosera binata 'multifida extrema'?

Can you put drosera binata 'multifida extrema' straight into a much bigger pot?

No. Even a fast-growing drosera binata 'multifida extrema' should only go up one pot size at a time. A vastly oversized pot holds a reservoir of wet soil the roots cannot reach, which stays cold and soggy and rots the roots — the opposite of what you wanted.

Should you fertilise drosera binata 'multifida extrema' after repotting?

Not immediately. Wait about 4 weeks after repotting drosera binata 'multifida extrema'. Fresh mix already contains nutrients, and feeding freshly cut or disturbed roots burns them. Resume your normal feeding routine once you see new growth.
