About Gomphrena haageana 'Strawberry Fields'

Gomphrena haageana 'Strawberry Fields' · also called Strawberry Fields Globe Amaranth, Red Globe Amaranth · flowering

'Strawberry Fields' is a globe amaranth grown for its vivid strawberry-red, papery flower heads on long stems. A heat- and drought-tolerant warm-season annual, it blooms prolifically from summer until frost, draws butterflies, and dries beautifully as an everlasting. It thrives in full sun and lean, free-draining soil and resents cold, wet conditions.

Mature size: 45-60 cm tall and 30 cm wide

Watch for — Root rot in wet soil: This drought-lover rots in soggy ground; plant in sharply drained soil and let it dry between waterings.

How to tell gomphrena haageana 'strawberry fields' needs repotting

Repotting on a calendar is less reliable than reading the plant. For gomphrena haageana 'strawberry fields', 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 haageana 'strawberry fields' 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 haageana 'strawberry fields'

Pot on seedlings as they grow; not a perennial repot. Gomphrena haageana 'Strawberry Fields'is grown for one season, so the question is really “how often to pot on” — keep moving it up before the roots circle. Upright, bushy and well-branched warm-season annual with wiry stems carrying rounded, cone-like red flower heads above grey-green foliage; somewhat more open and stem-forward than G. globosa..

What size pot to step gomphrena haageana 'strawberry fields' up to

Pot gomphrena haageana 'strawberry fields' 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 haageana 'strawberry fields'

Pot gomphrena haageana 'strawberry fields' 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 haageana 'strawberry fields'

Pot on before it is root-bound. Check gomphrena haageana 'strawberry fields' 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 light, well-drained, average to poor soil 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 haageana 'strawberry fields' 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 haageana 'strawberry fields'

Gomphrena haageana 'Strawberry Fields' wants light, well-drained, average to poor soil. Grows best in free-draining soil of pH 6.0-7.0 and tolerates dry, sandy and lean conditions. Avoid rich, heavy or waterlogged ground, which reduces bloom and encourages rot; drainage is the priority. 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 haageana 'strawberry fields' — frequently asked questions

How often should you repot gomphrena haageana 'strawberry fields'?

Pot on seedlings as they grow; not a perennial repot for gomphrena haageana 'strawberry fields'. Gomphrena haageana 'Strawberry Fields' is a seasonal crop, so you pot it on as a growing plant rather than repotting a perennial. Step seedlings up gradually into light, well-drained, average to poor soil 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 haageana 'strawberry fields' need?

When is the best time of year to repot gomphrena haageana 'strawberry fields'?

Can you put gomphrena haageana 'strawberry fields' straight into a much bigger pot?

No. Even a fast-growing gomphrena haageana 'strawberry fields' 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 haageana 'strawberry fields' after repotting?

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