About Strawberry Fields gomphrena

Gomphrena haageana 'Strawberry Fields' · also called Strawberry Fields gomphrena, Strawberry Fields globe amaranth · flowering

A bold, vibrant annual bearing conical, strawberry-red flower-heads on tall, upright 60–75 cm stems. Gomphrena haageana 'Strawberry Fields' is prized for its exceptional heat tolerance, long-lasting colour from summer to frost, and superb vase life both fresh and dried. A standout cut flower and border accent for hot, sunny gardens.

Mature size: 60–75 cm tall, 30–45 cm wide

Watch for — Root and stem rot from poor drainage: The greatest threat to 'Strawberry Fields' is waterlogged soil. Plant in raised beds or mounded rows if drainage is imperfect; do not overwater, particularly in cooler UK summers.

How to tell strawberry fields gomphrena needs repotting

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

Pot on seedlings as they grow; not a perennial repot. Strawberry Fields gomphrenais grown for one season, so the question is really “how often to pot on” — keep moving it up before the roots circle. Upright, branching annual; tall cut-flower habit.

What size pot to step strawberry fields gomphrena up to

Pot strawberry fields gomphrena 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 strawberry fields gomphrena

Pot strawberry fields gomphrena 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 strawberry fields gomphrena

Pot on before it is root-bound. Check strawberry fields gomphrena 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 well-drained loam or sandy loam, average fertility 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 strawberry fields gomphrena 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 strawberry fields gomphrena

Strawberry Fields gomphrena wants well-drained loam or sandy loam, average fertility. Average, well-drained garden soil suits this species well. Overly rich soils can reduce flowering. Tolerates sandy and slightly alkaline conditions. Work in a modest amount of compost at planting if soil is very poor. pH 5.5–7.5. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting strawberry fields gomphrena — frequently asked questions

How often should you repot strawberry fields gomphrena?

Pot on seedlings as they grow; not a perennial repot for strawberry fields gomphrena. Strawberry Fields gomphrena is a seasonal crop, so you pot it on as a growing plant rather than repotting a perennial. Step seedlings up gradually into well-drained loam or sandy loam, average fertility 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 strawberry fields gomphrena need?

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

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

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

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