About Calathea Louisae 'Maui Queen'
Goeppertia louisae 'Maui Queen' · also called Calathea Maui Queen · houseplant
'Maui Queen' is a louisae cultivar with elongated green leaves marked by a bold pale-green to creamy feathered brushstroke down the centre, set over wine-purple undersides. A prayer plant, it folds upward at night. It needs warmth, even moisture, high humidity and bright indirect light, and resents hard tap water and chill indoors.
Growth habit: Clump-forming basal rosette; petioles emerge upright and arch, with leaves raising and lowering daily in the nyctinastic prayer-plant rhythm.
Watch for — Browning leaf edges and tips: Low humidity or fluoride, chlorine and salt buildup from tap water. Use filtered or rainwater, raise humidity, and keep moisture consistent.
What fertiliser calathea louisae 'maui queen' actually wants — and why
Calathea Louisae 'Maui Queen' 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 calathea louisae 'maui queen': 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 calathea louisae 'maui queen', 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 calathea louisae 'maui queen':
Feed monthly in spring and summer with a balanced liquid houseplant fertiliser at half strength. As calatheas are salt-sensitive, keep doses light and flush the soil periodically with plain water to clear salts. Stop feeding through the autumn and winter rest. 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 calathea louisae 'maui queen' 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 calathea louisae 'maui queen'
Half strength is the safe default for calathea louisae 'maui queen' — 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 calathea louisae 'maui queen' first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the calathea louisae 'maui queen' watering schedule.
Signs you are over-feeding calathea louisae 'maui queen'
Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for calathea louisae 'maui queen':
- 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 calathea louisae 'maui queen'
- 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 calathea louisae 'maui queen' care brief covers soil, humidity and the common problems for this species.
Flushing and leaching the salts
Flush the pot of calathea louisae 'maui queen' 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 calathea louisae 'maui queen'
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.
