About Anemone coronaria 'Mr. Fokker'
Anemone coronaria 'Mr. Fokker' · also called Mr. Fokker anemone, blue poppy anemone · flowering
Mr. Fokker is a classic single poppy anemone from the De Caen group, with rich violet-blue petals encircling a black centre ringed by dark stamens. Grown from soaked corms planted in autumn or late winter, it flowers in spring on slender stems and makes an excellent cut flower. Being a buttercup relative, it is toxic to cats and dogs.
Growth habit: Tuberous perennial growing from a small knobbly corm, forming a low rosette of ferny foliage with single poppy-form flowers on wiry upright stems.
What fertiliser anemone coronaria 'mr. fokker' actually wants — and why
Anemone coronaria 'Mr. Fokker' 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 anemone coronaria 'mr. fokker': 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 anemone coronaria 'mr. fokker', 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 anemone coronaria 'mr. fokker':
Feed every 2-3 weeks during active growth with a balanced or potassium-leaning liquid fertiliser, from established foliage through the long flowering period. Reduce feeding as the plants begin to die back. Treat that as every 2-3 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 anemone coronaria 'mr. fokker' 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 anemone coronaria 'mr. fokker'
Half strength is the safe default for anemone coronaria 'mr. fokker' — 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 anemone coronaria 'mr. fokker' first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the anemone coronaria 'mr. fokker' watering schedule.
Signs you are over-feeding anemone coronaria 'mr. fokker'
Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for anemone coronaria 'mr. fokker':
- 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 anemone coronaria 'mr. fokker'
- 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 anemone coronaria 'mr. fokker' care brief covers soil, humidity and the common problems for this species.
Flushing and leaching the salts
Flush the pot of anemone coronaria 'mr. fokker' 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 anemone coronaria 'mr. fokker'
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.
