Yellow Begonia grandiflora - Begonia bulbs

Plant your begonias in a shady or slightly sunny location, in light and moist soil rich in humus. Begonias are sensitive to heavy soils, so lighten it if necessary with some sand. Plant them after the last frost, one per pot with a diameter of about twenty centimeters, or spaced 25 centimetres (10 inches) apart in open ground. Plant the begonia with the hollow side up and cover with 5 centimetres (2 inches) of soil. Like dahlias, you can speed up their growth cycle by planting them as early as February in a pot, kept sheltered, and then taking them outside in May. Water regularly. Apply begonia fertilizer at 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 bit of turf, in a dry and cool place, during the winter.
