Red Begonia grandiflora - Begonia bulbs

Plant your begonias in a shady or lightly sunny location, in light and moist soil rich in humus. Begonias don't tolerate heavy soils, so lighten it if necessary with some sand. Plant them after the last frost, one per pot of about 20cm (8in), or spaced 25cm (10in) apart in open ground. Plant begonia with the hollow side up, and cover with 5cm (2in) of soil. Just like with Dahlias, you can speed up their growth cycle by planting them as early as February, in a pot, kept sheltered, and taking them out in May. Water regularly. Apply begonia fertilizer at planting, and then twice a month during the growing season. Remove faded flowers. Dig up the bulbs before the first frost, and store them in a bit of turf, in a dry and cool place, during the winter.
