About Begonia 'Non-Stop Rose'

Begonia × tuberhybrida 'Non-Stop Rose' · also called Non-Stop Rose begonia, double tuberous begonia · flowering

A tuberous begonia from the Non-Stop series, 'Non-Stop Rose' produces large, fully double, rose-pink blooms above mounded green foliage all summer. Bred for upright container and bedding display in shade and part shade, it grows from a dormant tuber that can be lifted and stored frost-free over winter and regrown the following spring.

Mature size: 25-30 cm tall and 25-30 cm wide

How to tell begonia 'non-stop rose' needs repotting

Repotting on a calendar is less reliable than reading the plant. For begonia 'non-stop rose', 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 'non-stop rose' 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 'non-stop rose'

Lift and divide every 3–4 years once clumps congest. Rather than a true repot, begonia 'non-stop rose' is lifted and divided once the clump congests and flowering drops off. Upright to slightly spreading, bushy and mounding, with double camellia-like flowers held above the foliage. Grows annually from a dormant tuber..

What size pot to step begonia 'non-stop rose' up to

Pot size matters less than depth and spacing here. When you replant begonia 'non-stop rose', 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 'non-stop rose'

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 'non-stop rose' in full growth or flower sets it back badly.

Step-by-step: repotting begonia 'non-stop rose'

Wait for dormancy. Let begonia 'non-stop rose' 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, humus-rich potting mix 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 'non-stop rose', 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 'non-stop rose'

Begonia 'Non-Stop Rose' wants rich, free-draining, humus-rich potting mix. A peat-free compost enriched with leaf mould or organic matter and lightened with perlite suits tuberous begonias. Slightly acidic pH and excellent drainage are essential to prevent tuber 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 begonia 'non-stop rose' — frequently asked questions

How often should you repot begonia 'non-stop rose'?

Lift and divide every 3–4 years once clumps congest for begonia 'non-stop rose'. Begonia 'Non-Stop Rose' 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, humus-rich potting mix. Crowding, not pot size, is what reduces flowering over time.

What size pot does begonia 'non-stop rose' need?

When is the best time of year to repot begonia 'non-stop rose'?

Do you "repot" begonia 'non-stop rose', or lift and divide it?

You lift and divide it. Begonia 'Non-Stop Rose' 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 'non-stop rose' after repotting?

Hold off feeding begonia 'non-stop rose' 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.
