About Achimenes 'Tarantella'

Achimenes 'Tarantella' · also called tarantella achimenes · flowering

Achimenes 'Tarantella' is a vigorous hot water plant cultivar bearing vivid rose-pink, flat-faced flowers in profusion through the warm months. Grown from small scaly rhizomes, it wants warmth, steady moisture, and humid air to bloom heavily. It trails well in baskets, dies back to dormant rhizomes after flowering, and is stored dry and cool until restarted in spring.

Mature size: About 30-45 cm long with a generous cascading spread when grown in a basket and pinched.

Watch for — Sparse flowering: Low light or too much nitrogen favours leaves over blooms. Give bright indirect light and switch to a high-potash bloom feed in summer.

How to tell achimenes 'tarantella' needs repotting

Repotting on a calendar is less reliable than reading the plant. For achimenes 'tarantella', watch for these signs:

Roots spiralling thickly out of the drainage holes or pushing the whole plant up out of the pot.
The pot is so packed that water runs straight through in seconds and barely wets the soil.
It has split a plastic pot, or the rootball is a solid mass with almost no soil left when you slide it out.
Growth and (for achimenes 'tarantella') flowering have clearly stalled despite good light and feeding — but remember this plant likes being snug, so a little crowding alone is not a reason to repot.

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 achimenes 'tarantella'

Only every 2–4 years, when genuinely crowded. Achimenes 'Tarantella' is one of the plants that genuinely prefers a snug pot — it grows and flowers better with its roots a little restricted, so resist the urge to repot it on schedule. Free-flowering herbaceous cultivar with a trailing, well-branched habit from small scaly rhizomes; superb in hanging baskets and mixed flowering displays..

What size pot to step achimenes 'tarantella' up to

Go up only one pot size — roughly 2–3 cm (about an inch) wider in diameter, no more. Achimenes 'Tarantella' positively prefers a snug pot: it flowers and grows better when the roots are a little restricted. The single biggest repotting mistake here is over-potting — dropping achimenes 'tarantella' into a pot two or three sizes up. All that surplus soil holds water the small root system cannot use, stays cold and wet, and rots the roots within weeks. When in doubt, choose the smaller pot.

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 achimenes 'tarantella'

Early spring, just as new growth restarts, is the ideal window for achimenes 'tarantella'. The plant is moving into its strongest growth phase and re-roots into fresh soil quickly. Avoid repotting in winter dormancy or, for flowering plants, while it is in bud or bloom — recovery is slowest then and you risk dropping the flowers.

Step-by-step: repotting achimenes 'tarantella'

Confirm it actually needs it. Slide achimenes 'tarantella' out and check the roots. Only continue if it is genuinely packed — this plant prefers a snug pot, so if there is still soil and room, put it straight back.
Pick a pot only one size up. Choose a pot just 2–3 cm wider with good drainage. Resist anything bigger; over-potting is the main killer here.
Ease it out gently. Water lightly the day before, then tip achimenes 'tarantella' out, supporting the base. Tease the outer roots free only enough to stop them circling.
Repot at the same depth. Add a layer of fresh light, humus-rich, free-draining mix, set the plant so the soil line sits exactly where it did before, and backfill around the sides, firming lightly.
Settle it in. Water once to settle the soil, then let it sit. Hold off on more water until the top of the soil dries — fresh soil around a small root system stays wet for a while.

Aftercare

Because the new soil holds more water than the old crammed rootball did, ease right back on watering — let the top of the soil dry before you water achimenes 'tarantella' again, or you will rot the roots in the very pot you just moved it to. Keep it out of harsh direct sun for a fortnight. Do not fertilise for about 4 weeks — fresh mix already carries nutrients and feeding freshly disturbed roots scorches them.

The right soil mix for achimenes 'tarantella'

Achimenes 'Tarantella' wants light, humus-rich, free-draining mix. A peat/coir African violet-style blend with perlite and leaf mould retains moisture while draining freely, guarding the delicate rhizomes against rot. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting achimenes 'tarantella' — frequently asked questions

How often should you repot achimenes 'tarantella'?

Only every 2–4 years, when genuinely crowded for achimenes 'tarantella'. Only repot achimenes 'tarantella' every 2–4 years, and only when it is genuinely root-bound — it flowers and grows best slightly crowded. Step up just one pot size in spring using light, humus-rich, free-draining mix. The key mistake is over-potting: a too-big pot stays wet and rots the roots.

What size pot does achimenes 'tarantella' need?

When is the best time of year to repot achimenes 'tarantella'?

Does achimenes 'tarantella' like to be root-bound?

Yes — achimenes 'tarantella' genuinely flowers and grows best when slightly pot-bound, so do not rush to repot it. The mistake to avoid is over-potting into a much larger pot: the excess soil stays wet, the roots cannot use it, and the plant rots. Only repot every few years and only one snug size up.

Should you fertilise achimenes 'tarantella' after repotting?

Not immediately. Wait about 4 weeks after repotting achimenes 'tarantella'. Fresh mix already contains nutrients, and feeding freshly cut or disturbed roots burns them. Resume your normal feeding routine once you see new growth.
