About Microsorum pteropus 'Windelov'
Microsorum pteropus 'Windelov' · also called Windelov Java fern, lace Java fern · tropical
Microsorum pteropus 'Windelov' is a lace-leaf Java fern cultivar whose frond tips split into fine, frilly fingers, giving a delicate crested look. Like the standard Java fern it is an epiphyte grown on wood or rock, thrives in low light, and is exceptionally hardy. It spreads via frond plantlets into ornate, finely-tipped green clusters.
Preferred mix: None; epiphyte attached to wood or rock
Why microsorum pteropus 'windelov' needs this mix
Microsorum pteropus 'Windelov' is an easy-going houseplant — it just wants a free-draining general mix that holds some moisture but never stays soggy.
- Microsorum pteropus 'Windelov' 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 microsorum pteropus 'windelov' 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 microsorum pteropus 'windelov''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 microsorum pteropus 'windelov'.
pH — does it matter for microsorum pteropus 'windelov'?
Microsorum pteropus 'Windelov' is not fussy about pH — a slightly acidic to neutral mix (around pH 6.0-7.0), which a standard peat-free compost provides, is perfectly fine. No testing needed.
If you want to check or adjust it, the soil pH guide walks through testing and the safe ways to nudge a mix more acidic or more alkaline.
