Wax Begonias grow best in bright indirect sunlight coming from a south, east, or west window.
They will do best when given consistent moisture conditions, and they react badly to drought. Moderately rich, well-drained soil in a full-sun to part-shade location will allow these plants to thrive with little care.
Wax begonias are not difficult plants to grow indoors and can be included in a massed windowsill planting for bright indoor color. To keep the plants looking vibrant, pinch off old blooms and keep the plant free of brown and old leaves.
