Paphiopedilum malipoense · also called Maliopo Slipper Orchid, Jade Slipper Orchid · flowering
Paphiopedilum malipoense is a striking Chinese slipper orchid famed for large jade-green flowers veined in maroon, carried singly on a tall slow-rising stem and faintly raspberry-scented. A terrestrial, terrestrial-loving cool grower with mottled foliage, it needs a winter chill to bloom and never tolerates drying out completely.
Growth habit: Sympodial terrestrial slipper orchid forming a low fan of mottled leaves per growth; a tall single flower stem rises slowly over weeks before opening one large bloom.
Watch for — Brown leaf tips: Mineral build-up from hard water or fertiliser salts. Switch to rain or RO water and flush the mix regularly.
What fertiliser paphiopedilum malipoense actually wants — and why
Paphiopedilum malipoense is feeding to flower, not to grow leaves — it needs a higher-phosphorus / specialist bloom feed, given little and often, to set and hold its display.
A higher-phosphorus "bloom" formula or a species-specific feed (orchid food, African violet food, or a tomato-style high-potash/phosphorus liquid). A high-nitrogen general feed gives you lush leaves and almost no flowers.
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 paphiopedilum malipoense: 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 paphiopedilum malipoense, 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 paphiopedilum malipoense:
Feed at quarter strength every two to three waterings year-round, since it never goes fully dormant, and flush with plain water in between. A balanced orchid feed with occasional calcium-magnesium supports this limestone dweller. The pattern that matters: feed little and often through active growth and budding — sparingly through the growing season — and ease right off during the rest period that triggers the next flush.
The dormant-season rule matters more than the exact interval: skip feeding entirely when paphiopedilum malipoense 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 paphiopedilum malipoense
Very dilute — quarter strength, the classic "weakly, weekly" approach for paphiopedilum malipoense. These plants have fine roots that scorch easily and a steady trickle beats an occasional strong dose for flowering.
Feeding always goes onto already-damp soil, never dry roots — water paphiopedilum malipoense first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the paphiopedilum malipoense watering schedule.
Signs you are over-feeding paphiopedilum malipoense
Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for paphiopedilum malipoense:
- Lush green leaves but few or no flowers (too much nitrogen).
- Brown, scorched leaf tips and edges — a classic fine-root burn.
- White salt crust on the medium or pot, and stalled buds.
- Bud blast: buds forming then shrivelling and dropping.
Signs you are under-feeding paphiopedilum malipoense
- Sparse or no flowering despite good light and the right season.
- Smaller, paler new leaves and a generally weak, tired plant.
- Flowers that are smaller or fade faster than they should.
If the symptoms point at watering, light or roots rather than nutrition, the full paphiopedilum malipoense care brief covers soil, humidity and the common problems for this species.
Flushing and leaching the salts
Specialist and bloom feeds leave salts that scorch fine roots — flush paphiopedilum malipoense thoroughly with plain water until it runs clear every 4-6 weeks in the feeding season, and always between feeds for orchids.
Organic vs synthetic feeds for paphiopedilum malipoense
Organic options
Gentler options exist: a dilute seaweed feed (mildly potassium-rich) or worm-casting tea. UK: Westland seaweed, or a dilute tomato feed like Tomorite for bud-formers; US: Espoma Orchid! / Violet! or Neptune's Harvest. Lower burn risk, slower response.
Synthetic / liquid feeds
A species-matched bloom feed at quarter strength — UK: Baby Bio Orchid / African Violet food, or a high-potash Tomorite/Phostrogen for budding bloomers; US: Miracle-Gro Orchid or Bloom Booster, Schultz African Violet.
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 paphiopedilum malipoense — frequently asked questions
What fertiliser does paphiopedilum malipoense need?

What does over-feeding paphiopedilum malipoense look like?
Lush green leaves but few or no flowers (too much nitrogen). Brown, scorched leaf tips and edges — a classic fine-root burn. White salt crust on the medium or pot, and stalled buds. Bud blast: buds forming then shrivelling and dropping. Using an ordinary high-nitrogen houseplant feed on paphiopedilum malipoense is the headline mistake — you get a healthy-looking plant that simply refuses to bloom. The second is feeding through the rest period and breaking the dormancy cue it needs to set buds.
Should I flush the soil of paphiopedilum malipoense?
Specialist and bloom feeds leave salts that scorch fine roots — flush paphiopedilum malipoense thoroughly with plain water until it runs clear every 4-6 weeks in the feeding season, and always between feeds for orchids.
