How to Prune Cane-Like Begonias
Beguiling begonias (Begonia spp.) Are a large family of plants typically grouped by growth habit or look. Cane-like begonias have tough, bamboo-like stems and are prized for their strikingly patterned leaves, and lots of feature attractive and fragrant flowers as well. Often grown indoors, cane-like begonias thrive in warm, humid conditions and are generally hardy in U.S. Department of Agriculture hardiness zone 10 and warmer, but this may vary by species and cultivar. Prune cane-like begonias to control for size and also to encourage bushier growth.
Pinch off the top flames from each cane when they are about 6 inches tall. This will encourage lateral sprouting and bushier growth. Remove any recently developed canes that tower above the rest or don’t develop many leaves. Before pruning, clean your pruning tool of any dirt or plant debris. Dip pruning clippers or shears to your household disinfectant or alcohol. Don’t use bleach as it may be corrosive. Wipe them dry.
Remove old, brown canes into the ground, or when in a container, to the surface of the ground.
Cut younger canes back to about half their size or even further. Cane-like begonias can usually survive being cut down from two-thirds, which keeps crops controls and compact their contour.
