Philodendron erubescens 'Painted Lady' · also called Painted Lady, Variegated Blushing Philodendron · houseplant
A hybrid blushing philodendron prized for its show-stopping foliage: new leaves emerge bright neon-yellow on hot-pink petioles, maturing to dappled lime-and-green. A moderate climber, 'Painted Lady' wants warmth, bright indirect light and steady moisture, and rewards a moss pole with progressively larger, more colourful leaves.
Growth habit: Vining, self-heading-to-climbing hybrid with striking pink petioles; climbs a moss pole or totem and produces larger, more variegated leaves as it ascends.
Watch for — Brown leaf margins: Low humidity or salt accumulation scorches the soft young foliage. Raise humidity and flush the soil periodically.
What fertiliser philodendron painted lady × erubescens actually wants — and why
Philodendron Painted Lady × erubescens is a genuinely hungry tropical — in bright warmth it pushes growth fast and rewards a regular half-strength balanced feed all season.
A balanced liquid feed (even N-P-K) or a slightly nitrogen-leaning foliage feed — this is a big-leaved foliage plant putting on real size, so it wants steady nitrogen for lush leaves, not a bloom 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 philodendron painted lady × erubescens: 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 philodendron painted lady × erubescens, 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 philodendron painted lady × erubescens:
Feed every two to four weeks in spring and summer with a balanced liquid fertiliser at half strength to support vivid new growth. Reduce to monthly or stop over winter. Avoid over-feeding, which causes salt-burned tips. For a fast grower like this that means feeding regularly — about monthly — right through spring through early autumn (roughly March to September), tapering off only as light drops in autumn.
The dormant-season rule matters more than the exact interval: skip feeding entirely when philodendron painted lady × erubescens 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 philodendron painted lady × erubescens
Half strength every feed is the sweet spot for philodendron painted lady × erubescens: frequent enough to fuel fast growth, dilute enough that it never scorches even when you feed often.
Feeding always goes onto already-damp soil, never dry roots — water philodendron painted lady × erubescens first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the philodendron painted lady × erubescens watering schedule.
Signs you are over-feeding philodendron painted lady × erubescens
Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for philodendron painted lady × erubescens:
- Brown, scorched leaf tips and margins despite correct watering.
- A white salt crust on the soil or around the pot edge.
- Sudden leaf yellowing and drop shortly after a strong feed.
- Soft, weak, over-stretched growth that cannot support itself.
Signs you are under-feeding philodendron painted lady × erubescens
- New leaves coming in noticeably smaller than older ones.
- Pale, yellow-green older leaves and slow growth through peak summer.
- A general loss of vigour and gloss in a plant that should be racing away.
If the symptoms point at watering, light or roots rather than nutrition, the full philodendron painted lady × erubescens care brief covers soil, humidity and the common problems for this species.
Flushing and leaching the salts
Because you feed often, salts accumulate faster — flush the pot of philodendron painted lady × erubescens with plain water until it drains freely roughly every month through the feeding season to keep the root zone clean.
Organic vs synthetic feeds for philodendron painted lady × erubescens
Organic options
A diluted seaweed or fish-and-seaweed feed plus a yearly top-dress of worm castings supports fast growth without burn risk. UK: Westland seaweed or Baby Bio Organic; US: Neptune's Harvest or Espoma Indoor!.
Synthetic / liquid feeds

What does over-feeding philodendron painted lady × erubescens look like?
Brown, scorched leaf tips and margins despite correct watering. A white salt crust on the soil or around the pot edge. Sudden leaf yellowing and drop shortly after a strong feed. Soft, weak, over-stretched growth that cannot support itself. The mistake here is the opposite of most houseplants: under-feeding a fast tropical in peak season starves it, leaving small, pale new leaves and slow growth — but full-strength doses still burn it, so feed often and weak, not occasionally and strong.
Should I flush the soil of philodendron painted lady × erubescens?
Because you feed often, salts accumulate faster — flush the pot of philodendron painted lady × erubescens with plain water until it drains freely roughly every month through the feeding season to keep the root zone clean.
