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.
Imagine a window box or container brimming over with large sunny flowers that can reach 15 cm (6 inch) in diameter. It’s quite possible, if you choose to plant the friendly and bright Begonia 'Double Yellow' which will flaunt its double flowers between June and October. These yellow double begonia plants reach about 30 cm (1 foot) in height, only double in height what the flower spreads in diameter. It’s easy to see that if it is flowers you want, without foliage stealing too much of the limelight, double begonias are the way to go.
Begonia 'Double Yellow' will certainly bring the sunshine of summer up close to you on your patio or porch.

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.
