Begonia × tuberhybrida 'Nonstop Rose Petticoat' · also called nonstop rose petticoat begonia, double tuberous begonia · flowering

Begonia 'Nonstop Rose Petticoat' is a compact, upright tuberous begonia from the Nonstop series, with large double rose-pink blooms edged in a deeper picotee margin from summer to autumn. Its tidy bushy habit suits beds, borders, and patio pots in light shade. Frost-tender, it dies back to a dormant tuber and flowers freely and weather-tolerantly through the season.

Mature size: Typically 20-30 cm tall and around 20-30 cm wide, forming a neat mound.

How to tell begonia 'nonstop rose petticoat' needs repotting

Repotting on a calendar is less reliable than reading the plant. For begonia 'nonstop rose petticoat', watch for these signs:

Flowering has tailed off year on year and the clump has become congested and overcrowded.
Lots of leaf and few flowers — a classic sign that begonia 'nonstop rose petticoat' bulbs or tubers need lifting and dividing.
Bulbs visibly bursting the pot or pushing each other to the surface.
It is the natural dormancy window (foliage yellowed and died back) — the only safe time to lift and split.

How often to repot begonia 'nonstop rose petticoat'

Lift and divide every 3–4 years once clumps congest. Rather than a true repot, begonia 'nonstop rose petticoat' is lifted and divided once the clump congests and flowering drops off. Compact, upright tuberous tender perennial from the seed-raised Nonstop series; a bushy, well-branched mound 20-30 cm tall, set with large double rose-pink picotee-edged blooms from summer into autumn. Dies back to a dormant tuber in autumn for lifting and storage. Frost-tender and grown as a seasonal bedding and container plant..

What size pot to step begonia 'nonstop rose petticoat' up to

Pot size matters less than depth and spacing here. When you replant begonia 'nonstop rose petticoat', set the bulbs or tubers at the correct depth (a rough guide: two to three times their own height of soil over the top) and space them so they are not touching. A wide, shallow pot suits a clump better than a tall narrow one.

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 begonia 'nonstop rose petticoat'

The only safe window is dormancy: wait until the foliage has yellowed and died back naturally, lift and divide then, and replant before or at the start of the next growing season. Disturbing begonia 'nonstop rose petticoat' in full growth or flower sets it back badly.

Step-by-step: repotting begonia 'nonstop rose petticoat'

Wait for dormancy. Let begonia 'nonstop rose petticoat' foliage yellow and die back completely. Lifting while it is in growth wastes the energy it is storing for next year.
Lift carefully. Loosen the soil well away from the bulbs/tubers with a fork and ease the whole clump out without spearing them.
Separate the offsets. Gently pull the clump apart into individual bulbs or tubers. Keep only firm, healthy, blemish-free ones.
Replant at the right depth. Reset them in fresh rich, free-draining potting compost at the correct depth and spacing — not touching — so each has room to bulk up.
Water in and rest. Water once to settle them, then keep on the dry side until growth resumes. Do not feed until leaves are actively growing.

Aftercare

After replanting begonia 'nonstop rose petticoat', keep the soil barely moist — not wet — until shoots appear; bulbs and tubers rot in cold, saturated soil. Once leaves are growing strongly, resume normal watering. Hold off feeding until the plant is in active growth again.

The right soil mix for begonia 'nonstop rose petticoat'

Begonia 'Nonstop Rose Petticoat' wants rich, free-draining potting compost. Use a fertile, moisture-retentive yet well-drained compost; a quality peat-free multipurpose mix with added perlite suits pots, and humus-improved soil works in borders. Sharp drainage is essential to protect the fleshy tuber from rotting in the cool, damp conditions tuberous begonias dislike. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting begonia 'nonstop rose petticoat' — frequently asked questions

How often should you repot begonia 'nonstop rose petticoat'?

Lift and divide every 3–4 years once clumps congest for begonia 'nonstop rose petticoat'. Begonia 'Nonstop Rose Petticoat' is lifted and divided, not "repotted". Every 3–4 years, once the foliage has died back and it is dormant, lift the clump, separate the offsets, and replant at the correct depth in rich, free-draining potting compost. Crowding, not pot size, is what reduces flowering over time.

What size pot does begonia 'nonstop rose petticoat' need?

When is the best time of year to repot begonia 'nonstop rose petticoat'?

Do you "repot" begonia 'nonstop rose petticoat', or lift and divide it?

You lift and divide it. Begonia 'Nonstop Rose Petticoat' grows from bulbs or tubers, so instead of repotting you wait for dormancy, lift the congested clump, separate the healthy offsets, and replant them at the right depth and spacing. Doing this every 3–4 years restores flowering.

Should you fertilise begonia 'nonstop rose petticoat' after repotting?

Hold off feeding begonia 'nonstop rose petticoat' until it is in active growth again. Fresh soil already carries enough nutrients to get it re-established, and feeding disturbed roots too soon does more harm than good.
