About Lipstick Plant 'Mona Lisa'

Aeschynanthus radicans 'Mona Lisa' · also called Mona Lisa Lipstick Plant · flowering

'Mona Lisa' is a free-flowering lipstick plant with glossy, leathery green leaves on trailing stems and clusters of tubular red blooms that emerge from dark calyces like lipstick from a tube. An epiphytic Southeast Asian trailer, it thrives in a hanging basket with bright indirect light, warmth, humidity and a slightly dry-between-waterings routine.

Growth habit: Trailing, semi-vining epiphyte with cascading stems of waxy leaves, well suited to hanging baskets.

What fertiliser lipstick plant 'mona lisa' actually wants — and why

Lipstick Plant 'Mona Lisa' 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 lipstick plant 'mona lisa': 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 lipstick plant 'mona lisa', 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 lipstick plant 'mona lisa':

Feed every 2-4 weeks in spring and summer with a balanced or high-potassium houseplant feed at half strength to support blooming. Reduce to monthly or pause in winter. Treat that as every 2-4 weeks 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 lipstick plant 'mona lisa' 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 lipstick plant 'mona lisa'

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

Organic vs synthetic feeds for lipstick plant 'mona lisa'

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.
