About Dionaea muscipula 'Akai Ryu'
Dionaea muscipula 'Akai Ryu' · also called Red Dragon flytrap · tropical
Dionaea muscipula 'Akai Ryu' (Red Dragon) is a striking all-red Venus flytrap cultivar, deep maroon throughout leaves and traps rather than just the trap interior. It is a temperate bog plant requiring intense sun to hold its colour, pure water, permanently wet acidic peat, and a real winter dormancy. Slightly slower than green forms but exceptionally ornamental.
Growth habit: Low rosette of maroon-red leaves tipped with hinged, toothed snap-traps; flatter in winter, more erect in summer, with tall white spring flowers that contrast against the red foliage.
Watch for — Slower growth than green forms: Red cultivars carry less chlorophyll, so 'Akai Ryu' grows somewhat slower — give it maximum light rather than fertiliser.
What fertiliser dionaea muscipula 'akai ryu' actually wants — and why
Dionaea muscipula 'Akai Ryu' 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 dionaea muscipula 'akai ryu': 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 dionaea muscipula 'akai ryu', 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 dionaea muscipula 'akai ryu':
No root fertiliser. It feeds on captured insects; indoors offer a trap a live or rehydrated insect occasionally. Avoid meat, mineral feed, and pointlessly triggering the traps. Treat that as sparingly through the growing season 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 dionaea muscipula 'akai ryu' 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 dionaea muscipula 'akai ryu'
Half strength is the safe default for dionaea muscipula 'akai ryu' — 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 dionaea muscipula 'akai ryu' first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the dionaea muscipula 'akai ryu' watering schedule.
Signs you are over-feeding dionaea muscipula 'akai ryu'
Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for dionaea muscipula 'akai ryu':
- Brown, crispy leaf tips and edges with no sign of underwatering.
- A white, crusty salt deposit on the soil surface or pot rim.
- Weak, pale, stretched new growth that flops.
- Lower leaves yellow and drop while the soil is correctly watered.
Signs you are under-feeding dionaea muscipula 'akai ryu'
- Uniformly pale or yellow-green leaves, oldest first.
- Noticeably small new leaves and stalled growth in good light and season.
- A generally tired, lacklustre look despite correct watering and light.
If the symptoms point at watering, light or roots rather than nutrition, the full dionaea muscipula 'akai ryu' care brief covers soil, humidity and the common problems for this species.
Flushing and leaching the salts
Flush the pot of dionaea muscipula 'akai ryu' with plain water until it runs freely from the base every couple of months in the feeding season — it washes out the fertiliser salts that cause brown tips.
Organic vs synthetic feeds for dionaea muscipula 'akai ryu'
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.

Lower leaves yellow and drop while the soil is correctly watered. Feeding dionaea muscipula 'akai ryu' year-round on a fixed schedule, including dark winter months, is the most common mistake — it cannot use the nutrients in low light and the surplus simply burns the roots and crusts the soil.
Should I flush the soil of dionaea muscipula 'akai ryu'?
Flush the pot of dionaea muscipula 'akai ryu' with plain water until it runs freely from the base every couple of months in the feeding season — it washes out the fertiliser salts that cause brown tips.
