Tuberous begonias are tender and must remain frost free. For an earlier display, start the tubers in temporary pots in a greenhouse or bright, protected place from February to April, then move them outdoors once the risk of frost has passed.

'Dorset'
Double begonias are among summer’s most striking garden delights. Reflect the season with sunshine gold offset with purest white for a white-hot display of flowering begonias. These incandescent blooms are the result of years of careful grooming that prepares them to give their absolute best in your garden even if you’re not the most experienced of gardeners.
As aristocratic as any rose, and even more floriferous, Belgian-grown double begonias are justifiably famed the world over, and this combination is sure to be an absolute show-stopper that will have any visitor to your garden pausing for a moment just to admire the effect they create.

Grow begonias in light shade, protected from harsh winds. They need rich, reliably moist yet free-draining conditions. For containers, use peat-free multipurpose compost and make sure excess water can drain away easily.
Begonia tubers can be planted directly into patio containers or suitable borders in May, once frosts have passed. If planting into a border before shoots appear, mark the position so you know where to water and avoid disturbing the tuber.
Unlike pointed flower bulbs, begonia tubers are rounded with a shallow hollow on top. Plant with the hollow side facing upwards and the rounded side downwards, leaving the top of the tuber around 1–2cm below the soil or compost surface.
Space tubers approximately 15–20cm apart in container displays or 20–30cm apart in borders. This gives the developing plants enough room to form a generous, well-balanced display without becoming overcrowded.
Water after planting, then keep the compost only lightly moist while the tubers remain dormant. Once shoots appear and growth becomes established, water regularly without allowing the soil to become waterlogged or the containers to stand in water.
