Starting from Seed
Germinating begonias from seed is difficult. To start indoors, fill individual peat pots with a fertile commercial soil starter and moisten. Sprinkle the seeds on the surface of the soil as they need light to germinate. Place in a room with a constant temperature of 70-75°F. Cover with clear plastic wrap to maintain the soil moisture and temperature. Keep the soil moist. When seedlings appear, remove the plastic wrap and move to a sunny location.
Start seeds indoors in January or early February.
When to Plant
Where to Plant
The conditions under which begonias are planted will depend on the variety. Some begonia varieties require shade. Wax begonias tolerate full sun better than other varieties. They cannot tolerate high temperatures, so in warm areas they should be planted at least in partial shade.
Care and Maintenance
Remove spent flowers to encourage continuous flowering.
Cut back the plant in midsummer to encourage growth.
The most common pests associated with begonias include mealy bugs, spider mites, scales, slugs, and thrips.
