About Begonia 'Nonstop Joy White'
Begonia × tuberhybrida 'Nonstop Joy White' · also called nonstop joy white begonia, tuberous white begonia · flowering
Begonia 'Nonstop Joy White' is a tuberous bedding begonia bearing large, double, camellia-like pure white flowers all summer on compact, weather-tolerant plants. Grown as a half-hardy annual or lifted tuber, it suits shaded beds, pots and baskets, wanting partial shade, moist but free-draining soil and protection from frost. Tubers are stored dry over winter.
Preferred mix: Rich, moisture-retentive but free-draining potting compost
Watch for — Tuber rot: Overwet compost or damp winter storage rots the tuber. Use free-draining compost and store dried tubers cool, dry and frost-free.
Why begonia 'nonstop joy white' needs this mix
Begonia 'Nonstop Joy White' hates drying out, so it wants a mix that stays evenly moist — but it still needs perlite so "moist" never tips into "waterlogged".
- Begonia 'Nonstop Joy White' comes from damp, shaded forest floors and has fine roots that scorch and brown the moment the rootball dries — the mix has to hold a steady reserve.
- Coir and compost give that reserve, while perlite keeps enough air that the constantly-moist mix does not turn anaerobic.
- Even moisture also keeps its thin leaves from crisping at the edges, which is this plant’s most visible stress signal.

What goes wrong with the wrong mix
The wrong soil is one of the most common reasons begonia 'nonstop joy white' struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- A free-draining, gritty mix dries too fast for begonia 'nonstop joy white' — you get crispy brown edges and frond or leaf drop within days of one missed watering.
- A pure, airless peat mix swings the other way: it holds water but suffocates the fine roots and rots the crown.
- Letting the mix dry to the point it shrinks from the pot is very hard to re-wet evenly and stresses the plant badly.
Using a sharp, fast-draining "houseplant" or cactus-leaning mix that lets begonia 'nonstop joy white' dry out. It needs a moisture-retentive but still airy blend.
