About Anthurium andraeanum 'Alabama'
Anthurium andraeanum 'Alabama' · also called Alabama anthurium · tropical
Anthurium andraeanum 'Alabama' is a compact flamingo flower bred for glossy red, heart-shaped spathes held above dark leathery leaves. Like all andraeanum cultivars it blooms nearly year-round indoors given bright indirect light and warmth. Grow it in a chunky, fast-draining aroid mix and keep humidity high for the longest-lasting, most vividly coloured spathes.
Growth habit: Evergreen, clump-forming epiphytic perennial with an upright rosette of long-petioled, glossy heart-shaped leaves and showy red spathes on tall stalks.
Watch for — Brown leaf tips and edges: Usually low humidity or salt/fluoride build-up from tap water; raise humidity, flush the pot and use filtered or rainwater.
What fertiliser anthurium andraeanum 'alabama' actually wants — and why
Anthurium andraeanum 'Alabama' is feeding to flower, not to grow leaves — it needs a higher-phosphorus / specialist bloom feed, given little and often, to set and hold its display.
A higher-phosphorus "bloom" formula or a species-specific feed (orchid food, African violet food, or a tomato-style high-potash/phosphorus liquid). A high-nitrogen general feed gives you lush leaves and almost no flowers.
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 andraeanum 'alabama': 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 andraeanum 'alabama', 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 andraeanum 'alabama':
Feed every 4-6 weeks in spring and summer with a balanced houseplant fertiliser diluted to half strength, or use a high-phosphorus bloom feed to encourage spathes. Stop or reduce feeding in autumn and winter; flush the pot occasionally to clear salt build-up. The pattern that matters: feed little and often through active growth and budding — every 4-6 weeks — and ease right off during the rest period that triggers the next flush.
The dormant-season rule matters more than the exact interval: skip feeding entirely when anthurium andraeanum 'alabama' 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 andraeanum 'alabama'
Very dilute — quarter strength, the classic "weakly, weekly" approach for anthurium andraeanum 'alabama'. These plants have fine roots that scorch easily and a steady trickle beats an occasional strong dose for flowering.
Feeding always goes onto already-damp soil, never dry roots — water anthurium andraeanum 'alabama' first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the anthurium andraeanum 'alabama' watering schedule.
Signs you are over-feeding anthurium andraeanum 'alabama'
Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for anthurium andraeanum 'alabama':
- Lush green leaves but few or no flowers (too much nitrogen).
- Brown, scorched leaf tips and edges — a classic fine-root burn.
- White salt crust on the medium or pot, and stalled buds.
- Bud blast: buds forming then shrivelling and dropping.
Signs you are under-feeding anthurium andraeanum 'alabama'
- Sparse or no flowering despite good light and the right season.
- Smaller, paler new leaves and a generally weak, tired plant.
- Flowers that are smaller or fade faster than they should.
If the symptoms point at watering, light or roots rather than nutrition, the full anthurium andraeanum 'alabama' care brief covers soil, humidity and the common problems for this species.
Flushing and leaching the salts
Specialist and bloom feeds leave salts that scorch fine roots — flush anthurium andraeanum 'alabama' thoroughly with plain water until it runs clear every 4-6 weeks in the feeding season, and always between feeds for orchids.
Organic vs synthetic feeds for anthurium andraeanum 'alabama'
Organic options
Gentler options exist: a dilute seaweed feed (mildly potassium-rich) or worm-casting tea. UK: Westland seaweed, or a dilute tomato feed like Tomorite for bud-formers; US: Espoma Orchid! / Violet! or Neptune's Harvest. Lower burn risk, slower response.
Synthetic / liquid feeds
A species-matched bloom feed at quarter strength — UK: Baby Bio Orchid / African Violet food, or a high-potash Tomorite/Phostrogen for budding bloomers; US: Miracle-Gro Orchid or Bloom Booster, Schultz African Violet.
Brand names are examples, not endorsements, and UK and US ranges differ — check the label’s own NPK and dilution rate, since formulations change.

Bud blast: buds forming then shrivelling and dropping. Using an ordinary high-nitrogen houseplant feed on anthurium andraeanum 'alabama' is the headline mistake — you get a healthy-looking plant that simply refuses to bloom. The second is feeding through the rest period and breaking the dormancy cue it needs to set buds.
Should I flush the soil of anthurium andraeanum 'alabama'?
Specialist and bloom feeds leave salts that scorch fine roots — flush anthurium andraeanum 'alabama' thoroughly with plain water until it runs clear every 4-6 weeks in the feeding season, and always between feeds for orchids.
