About dark form scindapsus
Scindapsus treubii · also called dark form scindapsus, Treubii dark form · houseplant
Scindapsus treubii 'Dark Form' is a slow-growing, collector-grade aroid from Southeast Asia prized for its remarkably deep, near-black glossy foliage. It performs well in bright indirect light with allow-to-dry-slightly watering cadence, moderate humidity, and well-draining aroid mix. An excellent shingle vine when given a moss pole or plank.
Growth habit: Slow-growing shingling/climbing vine; leaves lie flat and overlap against the support surface when climbing; trailing in hanging baskets
Watch for — Slow growth or leggy stems: Typically caused by insufficient light. Move the plant closer to a bright indirect light source. 'Dark Form' is slow-growing even in ideal conditions, so patience is needed — do not over-fertilise to force growth.
What fertiliser dark form scindapsus actually wants — and why
dark form scindapsus 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 dark form scindapsus: 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 dark form scindapsus, 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 dark form scindapsus:
Feed monthly in spring and summer with a balanced liquid fertiliser at half strength. Alternatively use a slow-release fertiliser at the start of the growing season. Do not fertilise in autumn or winter when the plant is dormant. Treat that as monthly 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 dark form scindapsus 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 dark form scindapsus
Half strength is the safe default for dark form scindapsus — 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 dark form scindapsus first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the dark form scindapsus watering schedule.
Signs you are over-feeding dark form scindapsus
Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for dark form scindapsus:
- 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.
Signs you are under-feeding dark form scindapsus
- Uniformly pale or yellow-green leaves, oldest first.
- Noticeably small new leaves and stalled growth in good light and season.
- A generally tired, lacklustre look despite correct watering and light.

Flushing and leaching the salts
Flush the pot of dark form scindapsus 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 dark form scindapsus
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 dark form scindapsus look like?

Lower leaves yellow and drop while the soil is correctly watered. Feeding dark form scindapsus 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 dark form scindapsus?
Flush the pot of dark form scindapsus 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.
