About Blume's Typhonium
Typhonium blumei · also called Blume's Typhonium, Divaricate Typhonium · tropical
Blume's Typhonium is a compact tuberous aroid native to seasonally dry tropical regions of Southeast Asia. It produces arrow-shaped or hastate leaves and small maroon-purple spathes in summer, dying back to dormancy in the dry season. Grow in bright indirect light with excellent drainage and a warm, dry winter rest. A specialist tropical collector's plant.
Growth habit: Small tuberous geophyte; produces arrow-shaped to hastate leaves and brief summer spathes; fully dormant in dry season
What fertiliser blume's typhonium actually wants — and why
Blume's Typhonium 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 blume's typhonium: 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 blume's typhonium, 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 blume's typhonium:
Feed with a balanced liquid fertiliser (10-10-10, half-strength) every 4 weeks during the active growing season. Do not fertilise dormant tubers. A light top-dressing of balanced slow-release granules at the start of the growing season supports healthy corm and leaf development. Treat that as every 4 weeks 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 blume's typhonium 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 blume's typhonium
Half strength is the safe default for blume's typhonium — 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 blume's typhonium first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the blume's typhonium watering schedule.
Signs you are over-feeding blume's typhonium
Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for blume's typhonium:
- 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 blume's typhonium
- 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.

Flushing and leaching the salts
Flush the pot of blume's typhonium 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 blume's typhonium
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 blume's typhonium 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 blume's typhonium?
Flush the pot of blume's typhonium 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.
