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.
Begonia 'Cascade Yellow' are as yet not as well-known or as freely available as they should be. That’s to your advantage. After all, you don’t want a garden that looks like a carbon copy of everyone else’s. Be the first among your friends to plant Begonia 'Cascade Yellow' for a rich golden fountain of truly unique double cascading blooms. Try these yellow double trailing begonia bulbs in hanging baskets, or plant them in free-standing pots or raised beds. But do be aware that they are going to steal the show, so if you don’t want other blooms to be upstaged, then pots are the answer.

Plant calendar
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.
