About Aglaonema 'Emerald Beauty'
Aglaonema commutatum 'Emerald Beauty' · also called Emerald Beauty Chinese Evergreen · houseplant
Aglaonema 'Emerald Beauty', also sold as 'Maria', is a tough, dark-green Chinese Evergreen marbled with soft silver-grey along the veins. It is one of the most shade-tolerant aroids, shrugging off low light and irregular watering. Its deep green leaves resist fading, making it a reliable low-light office and home plant for beginners.
Growth habit: Slow-growing, clumping evergreen perennial forming a dense, upright bush of broad, dark-green leaves.
Watch for — Brown leaf tips: From dry air, fluoride or fertiliser salts. Use filtered or distilled water and flush the pot occasionally.
What fertiliser aglaonema 'emerald beauty' actually wants — and why
Aglaonema 'Emerald Beauty' 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 'emerald beauty': 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 'emerald beauty', 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 'emerald beauty':
Feed monthly through spring and summer with a balanced half-strength liquid houseplant fertiliser. Pause in autumn and winter. This light feeder is easily overfed, which browns the leaf margins, so err on the lean side. 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 'emerald beauty' 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 'emerald beauty'
Half strength is the safe default for aglaonema 'emerald beauty' — 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 'emerald beauty' first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the aglaonema 'emerald beauty' watering schedule.
Signs you are over-feeding aglaonema 'emerald beauty'
Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for aglaonema 'emerald beauty':
- 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 'emerald beauty'
- 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 'emerald beauty' 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 'emerald beauty'
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.
