About Hooker's Anchomanes
Anchomanes hookeri · also called Hooker's Anchomanes · tropical
Anchomanes hookeri is a West African tuberous aroid closely related to A. difformis, producing a single large, dissected compound leaf on a spiny, blotched petiole annually. A specialist collector's plant requiring tropical warmth, high humidity, rich loamy soil, and a strict dry-season dormancy. All parts are toxic due to calcium oxalate crystals typical of the Araceae family.
Growth habit: Tuberous, seasonally dormant geophytic aroid; single compound leaf per season
What fertiliser hooker's anchomanes actually wants — and why
Hooker's Anchomanes 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 hooker's anchomanes: 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 hooker's anchomanes, 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 hooker's anchomanes:
Feed monthly during active growth with a balanced liquid fertiliser (NPK 10-10-10 or similar) at half strength. Incorporate a slow-release granular fertiliser into the potting mix at planting time. No feeding during dormancy. 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 hooker's anchomanes 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 hooker's anchomanes
Half strength is the safe default for hooker's anchomanes — 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 hooker's anchomanes first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the hooker's anchomanes watering schedule.
Signs you are over-feeding hooker's anchomanes
Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for hooker's anchomanes:
- 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 hooker's anchomanes
- 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 hooker's anchomanes 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 hooker's anchomanes
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.

Lower leaves yellow and drop while the soil is correctly watered. Feeding hooker's anchomanes 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 hooker's anchomanes?
Flush the pot of hooker's anchomanes 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.
