Yucca is an evergreen, perennial plant with spine-tipped leaves that grow in a rosette around a thick central stem. More than 25 species of Yucca live in the arid regions of the southwest. One of the finest aspects of this desert plant is that it is low maintenance.
If its craggy look doesn’t bother you then it is not even necessary to prune it.
Trimming the Yucca plant is commonplace, especially for ornamental purposes. The best time to prune those rugged leaves is spring. While early spring is the ideal season, a yucca can be trimmed anytime. Just make sure the yucca plant gets plenty of light while it is recovering.
Cutting back a yucca may look harsh, but it is an attractive way to keep your plant manageable. When the Yucca completes flowering cut the stalk all the way to the ground with a sharp pair of lopping shears. To prevent cuts and scratches, wear heavy garden gloves.
Keep in mind that cutting the top off the yucca encourages the root system to push up new growth and more plants, called “pups” will appear. Hire professionals to do your yucca trimming if you are short on time.
Tidbits: The Apache Indians preferred the flowers of Yucca elata, a thin-leaf yucca, to those of the thick-leaf banana yucca. We know that these flowers were eaten thousands of years ago because unusually large amounts of yucca pollen have been found in some dried human feces collected from Hinds Cave.
