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.

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.

What fertiliser drosera binata 'multifida extrema' actually wants — and why

Drosera binata 'Multifida Extrema' is an easy, light foliage feeder — a half-strength balanced liquid feed through the growing months keeps it green without forcing weak, sappy growth.

A balanced general houseplant feed (roughly even N-P-K) is exactly right — it is grown for foliage, so steady, moderate nitrogen for healthy leaves is the goal, not a bloom or root formula.

For the language behind the three numbers on the bottle — what nitrogen, phosphorus and potassium each do — see the NPK ratio explained entry. The short version for drosera binata 'multifida extrema': match the feed to the job the plant is doing right now, not to a generic “plant food” on the shelf.

How often to feed drosera binata 'multifida extrema', and which months

Feeding only earns its keep while the plant is in active growth and can use the nutrients — pour feed into a dormant or low-light plant and it simply builds up as root-burning salt. For drosera binata 'multifida extrema':

Never feed the roots. The many forked tips catch their own insects; indoors a leaf can be fed a small rehydrated insect occasionally. Keep all fertiliser out of the media. Treat that as sparingly through the growing season between spring through early autumn (roughly March to September); ease off in autumn and stop entirely in the low light of winter.

The dormant-season rule matters more than the exact interval: skip feeding entirely when drosera binata 'multifida extrema' is resting. For the wider context on indoor feeding rhythms across the seasons, the houseplant fertiliser schedule walks through the year month by month.

What strength to mix for drosera binata 'multifida extrema'

Half strength is the safe default for drosera binata 'multifida extrema' — houseplant feeds are formulated strong, and the diluted dose is gentler on the roots while still ample for foliage.

Feeding always goes onto already-damp soil, never dry roots — water drosera binata 'multifida extrema' first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the drosera binata 'multifida extrema' watering schedule.

Signs you are over-feeding drosera binata 'multifida extrema'

Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for drosera binata 'multifida extrema':

Signs you are under-feeding drosera binata 'multifida extrema'

If the symptoms point at watering, light or roots rather than nutrition, the full drosera binata 'multifida extrema' care brief covers soil, humidity and the common problems for this species.

Flushing and leaching the salts

Flush the pot of drosera binata 'multifida extrema' with plain water until it runs freely from the base every couple of months in the feeding season — it washes out the fertiliser salts that cause brown tips.

Organic vs synthetic feeds for drosera binata 'multifida extrema'

Organic options

A diluted seaweed or worm-casting feed, or fish emulsion if you can tolerate the smell indoors. UK: Westland or Baby Bio Organic, dilute seaweed; US: Espoma Indoor! or Neptune's Harvest fish & seaweed. Slow, gentle and hard to overdo.

Synthetic / liquid feeds

A general-purpose houseplant liquid at half strength — UK: Baby Bio, Westland Houseplant Feed or Phostrogen; US: Miracle-Gro Indoor Plant Food or Schultz. Convenient and fast-acting; the only risk is overdoing it.

Brand names are examples, not endorsements, and UK and US ranges differ — check the label’s own NPK and dilution rate, since formulations change.

What does over-feeding drosera binata 'multifida extrema' look like?

Brown, crispy leaf tips and edges with no sign of underwatering. A white, crusty salt deposit on the soil surface or pot rim. Weak, pale, stretched new growth that flops. Lower leaves yellow and drop while the soil is correctly watered. Feeding drosera binata 'multifida extrema' year-round on a fixed schedule, including dark winter months, is the most common mistake — it cannot use the nutrients in low light and the surplus simply burns the roots and crusts the soil.

Should I flush the soil of drosera binata 'multifida extrema'?

Flush the pot of drosera binata 'multifida extrema' with plain water until it runs freely from the base every couple of months in the feeding season — it washes out the fertiliser salts that cause brown tips.
