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.

Mature size: 60-75 cm tall and 30 cm wide

Watch for — Root rot from overwatering: Wet, heavy soil rots the roots of this drought-lover; plant in free-draining ground and let it dry between waterings.

How to tell gomphrena globosa 'qis pink' needs repotting

Repotting on a calendar is less reliable than reading the plant. For gomphrena globosa 'qis pink', watch for these signs:

Roots circling the bottom of the module or pot, or poking out of the drainage holes.
The seedling dries out within a day and growth has visibly stalled.
Roots are white and matted in a tight spiral when you tip the plant out.
It has outgrown its current container for the stage of the season — pot gomphrena globosa 'qis pink' on before it becomes hard root-bound.

For the underlying biology of a pot-bound root system and why it stalls a plant, see our guide to spotting and fixing a root-bound plant.

How often to repot gomphrena globosa 'qis pink'

Pot on seedlings as they grow; not a perennial repot. Gomphrena globosa 'QIS Pink'is grown for one season, so the question is really “how often to pot on” — keep moving it up before the roots circle. 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 size pot to step gomphrena globosa 'qis pink' up to

Pot gomphrena globosa 'qis pink' on gradually — a seedling jumped straight into a huge pot sits in cold, wet, airless soil and stalls. Step up one or two sizes at a time as the roots fill each container, finishing in a large final pot or the ground. The aim is roots that never circle and never check.

Not sure of the exact diameter? Our pot size calculator takes the current pot and root spread and tells you the right next size — it deliberately recommends a single step up, never a big jump.

The best time of year to repot gomphrena globosa 'qis pink'

Pot gomphrena globosa 'qis pink' on through the active growing season, whenever roots fill the current container — there is no single date, just "before it becomes root-bound". Avoid potting on during a cold snap.

Step-by-step: repotting gomphrena globosa 'qis pink'

Pot on before it is root-bound. Check gomphrena globosa 'qis pink' regularly; move it up as soon as roots reach the edge of the cell or pot, not after they have circled.
Step up one or two sizes. Choose the next container up — not a giant one. Cold, wet, unused soil around a small root system stalls seedlings.
Knock it out gently. Support the stem, tip the pot, and ease the rootball out without breaking it. A little teasing of circled roots at the base is fine.
Pot into rich mix. Set it into fresh average, well-drained soil; tolerates poor and sandy ground at the same depth (tomatoes are the exception — they can go deeper to root along the stem).
Water in and grow on. Water well, keep it in good light, and resume feeding once it is established and growing again.

Aftercare

Water gomphrena globosa 'qis pink' in well and keep it in bright light; a freshly potted-on seedling can wilt for a day while roots settle, so do not overcompensate by drowning it. Do not fertilise for about 1 week — fresh mix already carries nutrients and feeding freshly disturbed roots scorches them.

The right soil mix for gomphrena globosa 'qis pink'

Gomphrena globosa 'QIS Pink' wants average, well-drained soil; tolerates poor and sandy ground. Thrives in light, free-draining soil of pH 6.0-7.0 and copes with lean, dry, sandy conditions. Rich, heavy or wet soil reduces flowering and invites rot; drainage matters far more than fertility. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting gomphrena globosa 'qis pink' — frequently asked questions

How often should you repot gomphrena globosa 'qis pink'?

Pot on seedlings as they grow; not a perennial repot for gomphrena globosa 'qis pink'. Gomphrena globosa 'QIS Pink' is a seasonal crop, so you pot it on as a growing plant rather than repotting a perennial. Step seedlings up gradually into average, well-drained soil; tolerates poor and sandy ground so the roots never circle the cell, ending in a large final container. A root-bound transplant stalls and never fully recovers.

What size pot does gomphrena globosa 'qis pink' need?

When is the best time of year to repot gomphrena globosa 'qis pink'?

Can you put gomphrena globosa 'qis pink' straight into a much bigger pot?

No. Even a fast-growing gomphrena globosa 'qis pink' should only go up one pot size at a time. A vastly oversized pot holds a reservoir of wet soil the roots cannot reach, which stays cold and soggy and rots the roots — the opposite of what you wanted.

Should you fertilise gomphrena globosa 'qis pink' after repotting?

Not immediately. Wait about 1 week after repotting gomphrena globosa 'qis pink'. Fresh mix already contains nutrients, and feeding freshly cut or disturbed roots burns them. Resume your normal feeding routine once you see new growth.
