About Calathea 'Maui Queen'
Goeppertia louisae 'Maui Queen' · also called Calathea 'Maui Queen', Maui Queen prayer plant · houseplant
Calathea 'Maui Queen' is a compact prayer plant grown for feathery green-and-cream variegated foliage that folds upward at night. It needs bright indirect light, evenly moist soil watered with filtered or rainwater, and 50-60% humidity. The ASPCA lists Calathea as non-toxic to cats, dogs, and horses, so it is pet-safe.
Growth habit: Compact, clumping rhizomatous perennial with an upright, tidy rosette of broad lance-shaped leaves. It is nyctinastic ("prayer plant"), folding its leaves upward in the evening and lowering them by day, producing audible rustling as foliage moves.
Watch for — Faded variegation or scorched, bleached patches: Too much direct sun bleaches and burns the foliage and washes out the green-and-cream pattern. Move to bright indirect light, away from direct rays.
What fertiliser calathea 'maui queen' actually wants — and why
Calathea '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 '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 '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 'maui queen':
Feed monthly during spring and summer with a balanced liquid houseplant fertiliser diluted to half strength. Stop feeding in autumn and winter when growth slows. Flush the soil with clean water periodically to prevent fertiliser-salt buildup, which can scorch the sensitive foliage. 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 '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 'maui queen'
Half strength is the safe default for calathea '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 '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 'maui queen' watering schedule.
Signs you are over-feeding calathea 'maui queen'
Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for calathea '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 '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 'maui queen' care brief covers soil, humidity and the common problems for this species.
Flushing and leaching the salts
Flush the pot of calathea '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 '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.

Lower leaves yellow and drop while the soil is correctly watered. Feeding calathea 'maui queen' 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 calathea 'maui queen'?
Flush the pot of calathea '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.
