About Audray White globe amaranth
Gomphrena globosa 'Audray White' · also called Audray White globe amaranth, Audray White gomphrena · flowering
A tall, vigorous globe amaranth with pristine white papery clover-like flowerheads on upright stems reaching 60–75 cm. Outstanding heat and drought tolerance makes it a reliable summer performer in cutting gardens and borders. Blooms hold their colour and shape when dried, making them a favourite for everlasting arrangements.
Growth habit: Upright, branching annual; tall cut-flower type
What fertiliser audray white globe amaranth actually wants — and why
Audray White globe amaranth 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 audray white globe amaranth: 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 audray white globe amaranth, 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 audray white globe amaranth:
Apply a balanced fertiliser (e.g. 10-10-10) at planting. One or two light supplemental feeds mid-season support tall-stemmed cut-flower production. Avoid high-nitrogen formulations that promote vegetative growth over blooms. 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 audray white globe amaranth 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 audray white globe amaranth
Half strength is the safe default for audray white globe amaranth — 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 audray white globe amaranth first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the audray white globe amaranth watering schedule.
Signs you are over-feeding audray white globe amaranth
Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for audray white globe amaranth:
- 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 audray white globe amaranth
- 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 audray white globe amaranth 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 audray white globe amaranth
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 audray white globe amaranth 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 audray white globe amaranth?
