About Aglaonema 'Lady Valentine'

Aglaonema 'Lady Valentine' · also called Lady Valentine Chinese Evergreen · houseplant

Aglaonema 'Lady Valentine' is a showy pink Chinese Evergreen with leaves heavily suffused in candy-pink and speckled green margins. The high pink content means it needs good indirect light to stay vivid and grows a little slower than green types. Warm, humid, draught-free conditions keep this eye-catching aroid colourful and healthy indoors.

Growth habit: Compact, clumping evergreen perennial forming an upright, bushy mound of vividly pink-variegated leaves.

Watch for — Brown patches on pink areas: The pink tissue is sensitive to dry air, sun and salts. Raise humidity, diffuse light and use filtered water.

What fertiliser aglaonema 'lady valentine' actually wants — and why

Aglaonema 'Lady Valentine' 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 'lady valentine': 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 'lady valentine', 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 'lady valentine':

Feed monthly in spring and summer with a balanced half-strength liquid houseplant fertiliser. Stop in autumn and winter. Because the pink foliage is sensitive, avoid overfeeding, which browns the leaf margins and pink patches. 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 'lady valentine' 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 'lady valentine'

Half strength is the safe default for aglaonema 'lady valentine' — 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 'lady valentine' first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the aglaonema 'lady valentine' watering schedule.

Signs you are over-feeding aglaonema 'lady valentine'

Organic vs synthetic feeds for aglaonema 'lady valentine'

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.
