About Bulbifer Voodoo Lily
Amorphophallus bulbifer · also called bulbifer voodoo lily, pink elephant foot · tropical
Amorphophallus bulbifer is one of the easier voodoo lilies, valued for a pretty pink-flushed spring inflorescence and a single marbled leaf. Uniquely it forms bulbils on its leaf where the segments meet, making it simple to propagate. It needs warmth and moisture in leaf, then a dry winter rest for the corm.
Growth habit: Tuberous perennial aroid producing a single marbled, divided leaf that bears bulbils, plus a pink-tinged spring inflorescence from an underground corm.
What fertiliser bulbifer voodoo lily actually wants — and why
Bulbifer Voodoo Lily 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 bulbifer voodoo lily: 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 bulbifer voodoo lily, 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 bulbifer voodoo lily:
Feed every 2-3 weeks during the growing season with a balanced liquid fertiliser to fatten the corm; a high-potash feed late in growth aids corm and bulbil development. Stop feeding as the leaf dies down. Treat that as every 2-3 weeks 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 bulbifer voodoo lily 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 bulbifer voodoo lily
Half strength is the safe default for bulbifer voodoo lily — 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 bulbifer voodoo lily first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the bulbifer voodoo lily watering schedule.
Signs you are over-feeding bulbifer voodoo lily
Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for bulbifer voodoo lily:
- 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 bulbifer voodoo lily
- 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.
If the symptoms point at watering, light or roots rather than nutrition, the full bulbifer voodoo lily care brief covers soil, humidity and the common problems for this species.
Flushing and leaching the salts
Flush the pot of bulbifer voodoo lily 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 bulbifer voodoo lily
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.

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. Feeding bulbifer voodoo lily 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 bulbifer voodoo lily?
Flush the pot of bulbifer voodoo lily 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.
