About Gomphrena globosa 'QIS Pink'
Gomphrena globosa 'QIS Pink' · also called QIS Pink Globe Amaranth, Cut-flower Globe Amaranth Pink · flowering
'QIS Pink' (Quality In Series) is a globe amaranth bred for cut flowers, with extra-long, sturdy stems carrying papery, clover-like pink clover-heads. This heat-loving, drought-tolerant warm-season annual blooms non-stop from summer to frost, attracts pollinators, and holds its colour superbly as a fresh or dried everlasting flower.
Growth habit: Upright, well-branched warm-season annual selected for tall, long, straight cut-flower stems topped with rounded, papery flower clusters held above the bushy foliage.
What fertiliser gomphrena globosa 'qis pink' actually wants — and why
Gomphrena globosa 'QIS Pink' 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 gomphrena globosa 'qis pink': 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 gomphrena globosa 'qis pink', 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 gomphrena globosa 'qis pink':
A light feeder. Work a little compost in at planting and apply a balanced liquid feed monthly at most. Over-fertilising, especially with nitrogen, produces floppy growth and fewer flowers; lean conditions give the best, longest-lasting blooms. Treat that as monthly 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 gomphrena globosa 'qis pink' 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 gomphrena globosa 'qis pink'
Half strength is the safe default for gomphrena globosa 'qis pink' — 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 gomphrena globosa 'qis pink' first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the gomphrena globosa 'qis pink' watering schedule.
Signs you are over-feeding gomphrena globosa 'qis pink'
Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for gomphrena globosa 'qis pink':
- 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 gomphrena globosa 'qis pink'
- 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 gomphrena globosa 'qis pink' care brief covers soil, humidity and the common problems for this species.
Flushing and leaching the salts
Flush the pot of gomphrena globosa 'qis pink' 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 gomphrena globosa 'qis pink'
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 gomphrena globosa 'qis pink' 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 gomphrena globosa 'qis pink'?
Flush the pot of gomphrena globosa 'qis pink' 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.
