About Treub's Scindapsus
Scindapsus treubii · also called Treubii Scindapsus, Dark Form Scindapsus · houseplant
Scindapsus treubii is a rare, slow-growing Araceae climber prized for its thick, dark blue-green to near-black velvety leaves. Give it bright indirect light and let the soil partly dry between waterings. It is toxic to pets and humans due to insoluble calcium oxalate crystals in all plant parts.
Preferred mix: Well-aerated chunky aroid mix
Watch for — Root rot: The most common killer. Ensure the pot has drainage holes and the chunky mix never stays waterlogged. Yellow, mushy stems at the base signal rot; remove affected roots and repot.
Why treub's scindapsus needs this mix
Treub's Scindapsus is a climbing rainforest aroid — it wants a chunky, bark-heavy mix full of air pockets, not a dense soil that packs around its thick roots.
- In the wild treub's scindapsus climbs trees with thick, partly aerial roots that expect air as much as moisture — bark and perlite recreate that open structure.
- A chunky mix drains fast but the coir and compost still hold a steady reservoir between waterings, which suits its "moist then slightly dry" rhythm.
- The big air gaps stop the dense, fast-growing root mass from compacting and choking itself.

What goes wrong with the wrong mix
The wrong soil is one of the most common reasons treub's scindapsus struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- Plain bagged compost packs tight around treub's scindapsus's thick roots, holds water in the centre and triggers the yellow-leaf-then-mushy-stem rot pattern.
- A fine, peaty mix with no bark leaves the roots gasping — growth slows and new leaves come out small and without fenestration.
- Too much moss or water-retaining additive keeps the core permanently wet and invites fungus gnats.
Using ordinary potting soil with no bark or perlite. Treub's Scindapsus needs roughly half its volume as chunky, airy material — that single change fixes most "mystery decline".
pH — does it matter for treub's scindapsus?
Treub's Scindapsus prefers a slightly acidic mix, around pH 5.5-6.5, which a peat-free compost-and-bark blend lands on naturally. It is not fussy enough to need testing in practice.
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.
DIY mix vs a bagged one
Bagged "aroid mix" is now widely sold and is a fine shortcut for treub's scindapsus, but check it actually contains visible bark and perlite — many are just rebranded compost. Mixing your own from the ratio above guarantees the structure.
Drainage and the pot
Any pot with a drainage hole works because the chunky mix does the draining. A pot only a little larger than the rootball avoids a wet, unused core; add a moss pole and the climbing roots will thank you.
Bark breaks down over time, so refresh the mix for treub's scindapsus every 12-18 months even if the pot size is still fine — spent, sludgy bark is a common hidden cause of decline. When the time comes, our repotting guide for treub's scindapsus covers the timing and technique step by step.
