Begonias, also called tuberous begonias, are often grown in pots. They also can make ideal hanging plants. Plant the upright varieties if desired, but typically, the trailing varieties are used in hanging baskets. For example, shrimp begonia (Begonia limmingheiana) is often grown in hanging baskets, blooming much of the year, including during the winter. Grow your hanging begonia indoors during the cool seasons and move them outdoors for the summer.
Choose a shallow container for growing begonias, such as a standard 30 cm (12 inch) pot. Select one that is moss lined to improve drainage if you are only growing your hanging begonia outdoors.
Place your hanging begonia in partial sunlight. An area that receives lots of direct morning sunlight and some afternoon shade is ideal. If your trailing begonias are not trailing over the sides of the container, they may need more light. Indoors, an east-facing window often works well.
Water a hanging begonia when the soil dries out slightly. Outdoors during the summer, you may need to water it every day. Indoors or during the winter, once a week may be all that is necessary.
Fertilise a mature, full-grown hanging begonia every other watering. Use an all-purpose liquid fertiliser and only use half the amount recommended on the label.
Prune a hanging begonia by simply pinching off the branches to help encourage fuller growth.
