About Aglaonema 'Creta'
Aglaonema 'Creta' · also called Creta Chinese Evergreen, Red Aglaonema Creta · houseplant
Aglaonema 'Creta' is a striking red-toned Chinese Evergreen with green leaves edged and veined in vivid pink-red. Like other coloured Aglaonemas it needs brighter indirect light than the green types to keep its red intensity. It is otherwise easy, forgiving of missed watering, and a popular bold accent plant for warm indoor spaces.
Growth habit: Clumping, upright evergreen perennial forming a dense bush of broad, red-edged leaves on short fleshy stems.
Watch for — Brown crispy edges: From dry air, fluoride or fertiliser salts. Raise humidity, use filtered water and flush the pot occasionally.
What fertiliser aglaonema 'creta' actually wants — and why
Aglaonema 'Creta' 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 aglaonema 'creta': 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 aglaonema 'creta', 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 aglaonema 'creta':
Feed monthly during spring and summer with a balanced half-strength liquid fertiliser to support the vivid colour. Suspend feeding in autumn and winter. Avoid overfeeding, which scorches the brightly coloured leaf edges. 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 aglaonema 'creta' 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 aglaonema 'creta'
Half strength is the safe default for aglaonema 'creta' — 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 aglaonema 'creta' first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the aglaonema 'creta' watering schedule.
Signs you are over-feeding aglaonema 'creta'
Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for aglaonema 'creta':
- 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 aglaonema 'creta'
- 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.

Flushing and leaching the salts
Flush the pot of aglaonema 'creta' 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 aglaonema 'creta'
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 aglaonema 'creta' 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 aglaonema 'creta'?
Flush the pot of aglaonema 'creta' 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.
