About Aglaonema Widuri
Aglaonema 'Widuri' · also called Widuri Aglaonema, Red Peacock · houseplant
Aglaonema 'Widuri', also sold as Red Peacock, is a vivid Indonesian hybrid with pink-flushed leaves edged in green and streaked with rose-red veins. The dramatic colour needs brighter indirect light than green types to develop fully. A showy yet easy-going tabletop plant that rewards warmth, even moisture and protection from cold.
Growth habit: Upright, self-branching clumping habit forming a bushy rosette of broad, colourful leaves. Slow to moderate grower that stays compact and full.
Watch for — Scorched or bleached leaves: Too much direct sun burns the coloured tissue. Filter strong light with a sheer curtain.
What fertiliser aglaonema widuri actually wants — and why
Aglaonema Widuri 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 widuri: 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 widuri, 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 widuri:
Feed monthly through spring and summer with a balanced, half-strength liquid houseplant fertiliser to support colour. Stop feeding in autumn and winter to prevent salt build-up and leaf burn. 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 widuri 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 widuri
Half strength is the safe default for aglaonema widuri — 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 widuri first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the aglaonema widuri watering schedule.
Signs you are over-feeding aglaonema widuri
Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for aglaonema widuri:
- 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 widuri
- 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 aglaonema widuri care brief covers soil, humidity and the common problems for this species.
Flushing and leaching the salts
Flush the pot of aglaonema widuri 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 widuri
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 does over-feeding aglaonema widuri look like?
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. Feeding aglaonema widuri 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 widuri?
Flush the pot of aglaonema widuri 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.
