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.
Preferred mix: Nutrient-free carnivorous mix
Watch for — Loss of dew: Low light, low humidity or disturbance. Brighten the light and keep roots wet; dew usually returns quickly.
Why drosera binata 'multifida extrema' needs this mix
Drosera binata 'Multifida Extrema' is an easy-going houseplant — it just wants a free-draining general mix that holds some moisture but never stays soggy.
- Drosera binata 'Multifida Extrema' is adaptable, but like most houseplants it still needs air at the roots — a mix that drains freely while holding a working moisture reserve.
- A little perlite or bark stops ordinary compost compacting into an airless block over time, which is the slow, common cause of decline.
- It is not fussy about pH or special ingredients; getting the air-to-moisture balance right is what matters.
For the full picture on what makes up a good mix, see our guide to the main types of soil and potting media — it explains why each ingredient above behaves the way it does.
What goes wrong with the wrong mix
The wrong soil is one of the most common reasons drosera binata 'multifida extrema' struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- Plain garden soil or a cheap, claggy compost compacts in the pot and slowly suffocates drosera binata 'multifida extrema''s roots.
- A pure peat mix that dries to a hard, water-repelling block is hard to re-wet and stresses the plant.
- No drainage hole turns even a good mix into a stagnant, root-rotting sump.
Reusing tired, compacted old compost or skipping the perlite. A free-draining mix in a pot with a hole solves most "why is it struggling" cases for drosera binata 'multifida extrema'.
