Pruning A Yucca
- 1). Prune dead or damaged leaves with a sharp knife or shears. Cut the leaves you remove as close as possible to the plant’s base.
- 2). After blooms are spent, cut flower stalks off at the base with a sharp knife or pruning shears. Leave the stalks until the seedheads open. The stage at which you prune the flower stalks is up to you and is purely a matter of aesthetics.
- 3). Removing young, budding plants helps curb the yucca’s spread. These young plants are called pups and are found at the parent plant’s base. If you don't mind your yucca spreading out, leave them. If you remove the pups, destroy them or plant them elsewhere in your garden or in containers.
