About Monstera Adansonii Wide Form
Monstera adansonii var. laniata · also called Wide form adansonii, Large form Swiss cheese vine · houseplant
The wide form of Monstera adansonii (var. laniata) has broader, glossier leaves than the common narrow form, with large oval fenestrations and a more pronounced sheen. This climbing Swiss cheese vine grows quickly on a moss pole in bright indirect light and warm, humid conditions. Like all Monstera, it is toxic to pets.
Growth habit: Vigorous evergreen climbing vine; the wide form produces broad, glossy leaves with large oval fenestrations, climbing strongly with aerial roots on a moss pole or trailing from a basket.
What fertiliser monstera adansonii wide form actually wants — and why
Monstera Adansonii Wide Form 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 monstera adansonii wide form: 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 monstera adansonii wide form, 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 monstera adansonii wide form:
Feed every 2-4 weeks in spring and summer with a balanced liquid fertiliser at half to full strength; this is a hungry, fast climber. Reduce in autumn and stop in winter. For a fast grower like this that means feeding regularly — about every 2-4 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 monstera adansonii wide form 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 monstera adansonii wide form
Half strength every feed is the sweet spot for monstera adansonii wide form: 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 monstera adansonii wide form first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the monstera adansonii wide form watering schedule.
Signs you are over-feeding monstera adansonii wide form
Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for monstera adansonii wide form:
- 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 monstera adansonii wide form
- 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 monstera adansonii wide form 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 monstera adansonii wide form 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 monstera adansonii wide form
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.

What does over-feeding monstera adansonii wide form 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 monstera adansonii wide form?
Because you feed often, salts accumulate faster — flush the pot of monstera adansonii wide form with plain water until it drains freely roughly every month through the feeding season to keep the root zone clean.
