How to Cut Bougainvillea Growth Back to the Ground

Bougainvillea vines grow up to 20 feet tall when they grow without pruning in a warm climate. They flower primarily during the winter months, producing a cascade of blossoms from the woody vines. Bougainvillea vines prefer subtropical and mild climates that rarely experience frost, although the plant can survive occasional frost with only minimal dieback. Cutting back a frost-damaged bougainvillea to the ground allows it to send up new vines that will flower the following year. Severe pruning also rejuvenates an overgrown vine so it's more compact.

Instructions

1. • 1

     Inspect the bougainvillea for dead vines after the last freeze in spring. Dead vines typically develop a darker, discolored appearance, have no living leaves, and are dry and brittle to the touch.

   • 2

     Cut back the dead vines at ground level with a sharp pair of shears. If the majority of the bougainvillea is dead or badly damaged, cut all the vines back to ground level.

     Trim back any remaining vines to within 1/4 inch of a leaf on the healthy part of the vine, removing only the frost damaged portion. Leaving some surviving vines on the plant when you cut it back helps ensure a full flower display the next winter.
