Begonia Sempoflorens

Origin: Hybrids
Height: 6-12 in (15-30 cm)
Light: Bright, indirect light. Begonias grow well under fluorescent lights, too. If you move your wax begonia outdoors for the summer, keep it shaded from hot, direct sun.
Water: Keep soil evenly moist all year. Overwatering will cause leaves to turn yellow.
Temperature: Cool nights (60°F/16°C) and warm days (65-75°F/18-24°C) will trigger flower buds.
Soil: Any good potting mix
Fertiliser: A steady diet of weak fertilizer will keep begonias happy. Feed monthly with a high-phosphorus (10-20-10) liquid fertiliser diluted by half.
Propagation: Take stem cuttings in spring and root in fresh potting mix. Keep soil lightly moist. Cover the whole container and plant with a plastic bag or cloche to hold in humidity. Wax begonia seeds are tiny and slow to germinate. You can sow seeds in spring, but it can take several months to grow.
