Prune in late winter or spring while the plant remains dormant. Remove all of a plumbago's dead and broken branches, advises North Carolina State Cooperative Extension. Use pruning shears to cut through branches with a diameter of 1/4 inch or less, and use loppers on larger branches.

Do you cut back plumbago in winter?

Prune plumbago more heavily during the winter once the plant stops blooming and becomes dormant. Cut back any old, tall, woody or diseased stems at the lateral joints and dispose of them. The plant will regrow during the following spring.

Should I prune my plumbago?

Prune Plumbagos regularly to maintain shape and form, and to prevent them from outgrowing their planting area. Plumbagos produce flowers on new wood and thus respond well to judicious pruning. Although they tolerate heavy pruning, cutting too frequently can adversely affect growth.
