About Chrysanthemum 'Yellow John Wingfield'
Chrysanthemum 'Yellow John Wingfield' · also called Yellow John Wingfield mum, exhibition chrysanthemum · flowering
A large-flowered exhibition chrysanthemum producing perfectly incurved yellow blooms of show quality in mid to late autumn. Bred for the show bench, it requires disbudding and staking. Toxic to cats, dogs, and horses. Popular among UK chrysanthemum societies for its precise incurved bloom form.
Growth habit: Upright herbaceous perennial grown as a stool-propagated annual display plant
Watch for — Earwigs: Feed on petals overnight, ruining show-quality blooms; trap in damp newspaper rolls placed around plants.
What fertiliser chrysanthemum 'yellow john wingfield' actually wants — and why
Chrysanthemum 'Yellow John Wingfield' 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 chrysanthemum 'yellow john wingfield': 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 chrysanthemum 'yellow john wingfield', 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 chrysanthemum 'yellow john wingfield':
Follow a structured programme: balanced feed in spring, high-nitrogen liquid feed fortnightly through summer for stem development, then high-potassium from late July through bud development. Stop feeding once petals are opening. 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 chrysanthemum 'yellow john wingfield' 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 chrysanthemum 'yellow john wingfield'
Half strength is the safe default for chrysanthemum 'yellow john wingfield' — 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 chrysanthemum 'yellow john wingfield' first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the chrysanthemum 'yellow john wingfield' watering schedule.
Signs you are over-feeding chrysanthemum 'yellow john wingfield'

- 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 chrysanthemum 'yellow john wingfield'
- 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 chrysanthemum 'yellow john wingfield' care brief covers soil, humidity and the common problems for this species.
Flushing and leaching the salts
Flush the pot of chrysanthemum 'yellow john wingfield' 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 chrysanthemum 'yellow john wingfield'
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.
