White Begonia grandiflora - Begonia bulbs

Plant your begonias in a shaded or lightly sunny area, in light and moist soil rich in humus. Begonias don't like heavy soils, so lighten it if necessary with some sand. Plant after the last frost, one per pot of about twenty cm, or spaced 25cm (10in) apart in the ground. Plant the begonia with the green hollow facing up, and cover with 5cm (2in) of soil. Like dahlias, you can speed up their cycle by planting them as early as February, in a pot, kept sheltered, and taking them out in May. Water regularly. Add begonia fertilizer when planting, and then twice a month during the season. Remove faded flowers. Dig up the bulbs before the first frost, and store them in a little peat, in a dry and cool place, during winter.
