Planting and Care
Space 6 to 8 inches apart for smaller plants and 8 to 12 inches apart for large plants.
Wax begonia can be overwintered indoors. Take 3 to 4” cuttings and root the in moist vermiculite or a well-drained potting mix. I find setting the pot in a plastic bag left open increases the humidity to encourage rooting without leading to rot. Once rooted, they can be moved to their permanent container, placed in a sunny location and grow as a houseplant.
You can also bring the whole plant indoors and raise it like a houseplant. Grow in a bright, sunny window or under artificial lights and keep the soil moist. Don't be alarmed if the plant drops most of its leaves. It will soon send out new leaves more suited for its indoor location.
