Annual Begonia Care Once appropriately placed in the flower bed or hanging basket, deadheading spent blooms and keeping the soil moist is the basis of annual begonia care. Watering correctly is important in the care of begonias. Soil should remain moist, but not too wet. A well-draining soil or potting mix simplifies this task. Water wax begonias at the base to avoid leaf spot and the possibility of fungal diseases. The most compact and healthy wax begonias result from deadheading and pinching back regularly. Annual begonia plants may be cut back before frost and used inside as a houseplant in winter. Once inside, keep the soil moist, provide humidity with a pebble tray and place in bright filtered light. Cuttings may be propagated for additional plants. Divide in spring for more outdoor begonia plants.
