About Aglaonema Super White
Aglaonema 'Super White' · also called Super White Chinese Evergreen, White Aglaonema · houseplant
Aglaonema 'Super White' is a slow-growing Chinese evergreen prized for near-white leaves veined and edged in green. The pale foliage means it needs more light than darker aglaonemas to avoid washing out, yet still tolerates indoor conditions. It thrives in warm, humid rooms with steady watering and dislikes cold, soggy roots.
Growth habit: Compact, clumping rosette of upright to slightly arching leaves emerging from a short central stem; bushy and tidy.
Watch for — Brown leaf edges: Usually low humidity, dry air from heating, or fluoride/salts in tap water; raise humidity and use filtered or rested water.
What fertiliser aglaonema super white actually wants — and why
Aglaonema Super White 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 super white: 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 super white, 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 super white:
Feed monthly through spring and summer with a balanced liquid houseplant fertiliser at half strength. Stop feeding in autumn and winter when growth slows. This is a light feeder; over-fertilising scorches leaf tips and builds up salts. 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 super white 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 super white
Half strength is the safe default for aglaonema super white — 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 super white first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the aglaonema super white watering schedule.
Signs you are over-feeding aglaonema super white
Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for aglaonema super white:
- 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 super white
- 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 super white 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 super white
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 fertiliser does aglaonema super white need?

What does over-feeding aglaonema super white look like?

Lower leaves yellow and drop while the soil is correctly watered. Feeding aglaonema super white 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 super white?
Flush the pot of aglaonema super white 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.
