A vast family of shrubs, lantanas (Lantana spp.) grow in U.S. Department of Agriculture plant hardiness zones 8 through 11. Typically, they bloom from spring until the first frost in fall. In mild climates, they often grow as evergreens. When temperatures dip to 28 degrees Fahrenheit, however, lantanas die back to the ground for winter. No matter the type, prune lantana yearly in early spring when new growth commences to prevent loss of blooms. Evergreen lantanas are easier to shape into a hedge, but ones that are herbaceous perennials can become a loose, informal hedge when it returns in spring.
Things You'll Need
- Pruning shears
- Bleach, disinfectant or rubbing alcohol
Sterilize pruning shears with a 1 part bleach and 9 parts water solution. This minimizes the risk of spreading disease that they might be harboring from previous tasks in the garden. You can also use a disinfectant spray or a solution made with equal parts water and rubbing alcohol.
Trim evergreen lantana stems up to one-third of their total height. Prune as desired to shape. You can also remove wayward, weak and damaged stems. Cut the stems sharply just above a branch union. Pruning branches just above outward-facing stems creates a fuller look.
Cut back a herbaceous perennial lantana 6 to 12 inches from the ground. Ensure you perform this task after the last spring frost. New growth will quickly sprout to form an informal hedge.
