How to fertilise Philodendron micans (Philodendron hederaceum var. hederaceum)— schedule & NPK
Also called velvet-leaf philodendron, micans.
About Philodendron micans
Philodendron hederaceum var. hederaceum · also called velvet-leaf philodendron, micans · tropical
Philodendron micans is a velvet-leaved trailing philodendron with iridescent bronze-green foliage that shifts purple in bright light. Forgiving and easy to propagate. Mildly toxic to pets.
The velvet-leaf form of Philodendron hederaceum, native through Mexico, the Caribbean and parts of Central America; differs from typical heartleaf chiefly by its matte, velvety leaf surface.
Feed a balanced water-soluble fertilizer about every 4–6 weeks in spring and summer, easing off in fall and winter as growth slows.
Growth habit: Trailing vine

What fertiliser philodendron micans actually wants — and why
Philodendron micans 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 micans: 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 micans, 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 micans:
Half-strength balanced feed every 4-6 weeks in growing season. For a fast grower like this that means feeding regularly — about every 4-6 weeks — 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 micans 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 micans
Half strength every feed is the sweet spot for philodendron micans: 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 micans first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the philodendron micans watering schedule.
Signs you are over-feeding philodendron micans
Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for philodendron micans:
- 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 micans
- 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 micans 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 micans 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 micans
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
A balanced houseplant liquid at half strength applied frequently — UK: Baby Bio, Phostrogen or Westland Houseplant Feed; US: Miracle-Gro Indoor Plant Food or Dyna-Gro Foliage-Pro for steady leafy growth.
Brand names are examples, not endorsements, and UK and US ranges differ — check the label’s own NPK and dilution rate, since formulations change.
Fertilising philodendron micans — frequently asked questions
What fertiliser does philodendron micans need?
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. Philodendron micans is a genuinely hungry tropical — in bright warmth it pushes growth fast and rewards a regular half-strength balanced feed all season.
How often should I feed philodendron micans?
Half-strength balanced feed every 4-6 weeks in growing season. Half-strength balanced feed every 4-6 weeks in growing season. For a fast grower like this that means feeding regularly — about every 4-6 weeks — right through spring through early autumn (roughly March to September), tapering off only as light drops in autumn.
What strength of feed for philodendron micans?
Half strength every feed is the sweet spot for philodendron micans: frequent enough to fuel fast growth, dilute enough that it never scorches even when you feed often.
What does over-feeding philodendron micans 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 micans?
Because you feed often, salts accumulate faster — flush the pot of philodendron micans with plain water until it drains freely roughly every month through the feeding season to keep the root zone clean.
