About Tiger Flower
Tigridia pavonia · also called Tiger flower, Mexican shell flower · flowering
Tigridia pavonia is a showy bulbous perennial from Mexico and Central America, producing exotic, large (10–15 cm), three-petalled flowers in vivid reds, pinks, oranges, yellows, and white — each heavily spotted at the centre — from midsummer through to early autumn. Individual flowers last only one day, but each stem carries multiple buds that open in succession over several weeks. It needs full sun, fertile well-drained soil, and warm summers to perform at its best; in cooler climates the bulbs should be lifted before the first frost. No toxicity to cats or dogs has been formally reported, but ingestion is still best avoided.
Growth habit: Cormous perennial with sword-shaped, pleated leaves forming fans similar to an iris; flowering stems are upright, branching, and reach 60–90 cm tall, each bearing multiple short-lived but spectacular blooms.
What fertiliser tiger flower actually wants — and why
Tiger Flower 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 tiger flower: 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 tiger flower, 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 tiger flower:
Apply a balanced granular fertiliser at planting, then feed with a liquid high-potassium feed every two weeks once flower buds form to prolong the flowering season. Treat that as sparingly through the growing season 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 tiger flower 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 tiger flower
Half strength is the safe default for tiger flower — 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 tiger flower first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the tiger flower watering schedule.
Signs you are over-feeding tiger flower
Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for tiger flower:
- 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 tiger flower
- 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 tiger flower care brief covers soil, humidity and the common problems for this species.
Flushing and leaching the salts
Flush the pot of tiger flower 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 tiger flower
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 tiger flower look like?
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 tiger flower 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 tiger flower?
Flush the pot of tiger flower 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.
