About Anthurium scherzerianum 'Rothschildianum'
Anthurium scherzerianum 'Rothschildianum' · also called Rothschild's pigtail anthurium, spotted flamingo flower · tropical
Anthurium scherzerianum 'Rothschildianum' is a pigtail-flower cultivar with white-to-pale spathes speckled red or pink and a distinctive curling, pigtail-like spadix. Native (as a species) to Costa Rican cloud forests, it is more sun- and cool-tolerant than andraeanum types. It wants bright indirect light, a chunky moist mix, and warm, humid conditions for repeat blooming.
Growth habit: Compact, clumping evergreen aroid forming an upright rosette of leathery lance-to-heart-shaped leaves, with spotted spathes and a characteristic curled, pigtail spadix held above the foliage.
Watch for — Few or no flowers: Most often too little light or excess nitrogen. Provide brighter indirect light and a higher-phosphorus feed to trigger the spotted spathes.
What fertiliser anthurium scherzerianum 'rothschildianum' actually wants — and why
Anthurium scherzerianum 'Rothschildianum' 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 anthurium scherzerianum 'rothschildianum': 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 anthurium scherzerianum 'rothschildianum', 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 anthurium scherzerianum 'rothschildianum':
Feed every 4-6 weeks in spring and summer with a balanced, water-soluble fertiliser at quarter to half strength to promote foliage and the spotted blooms. Reduce in winter and flush the pot periodically to prevent salt build-up that browns leaf tips. Treat that as every 4-6 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 anthurium scherzerianum 'rothschildianum' 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 anthurium scherzerianum 'rothschildianum'
Half strength is the safe default for anthurium scherzerianum 'rothschildianum' — 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 anthurium scherzerianum 'rothschildianum' first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the anthurium scherzerianum 'rothschildianum' watering schedule.
Signs you are over-feeding anthurium scherzerianum 'rothschildianum'
Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for anthurium scherzerianum 'rothschildianum':
- 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 anthurium scherzerianum 'rothschildianum'
- 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 anthurium scherzerianum 'rothschildianum' care brief covers soil, humidity and the common problems for this species.
Flushing and leaching the salts
Flush the pot of anthurium scherzerianum 'rothschildianum' 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 anthurium scherzerianum 'rothschildianum'
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 anthurium scherzerianum 'rothschildianum' 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 anthurium scherzerianum 'rothschildianum'?
Flush the pot of anthurium scherzerianum 'rothschildianum' 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.
