The yucca plant, a perennial evergreen, is part of the Agavaceae plant family, which includes around 50 species. Yucca plants consist of green dagger-like leaves with towering flower stalks growing in the center to heights ranging from 5 to 30 feet. These flowers bloom from summer to fall and most are edible. Outside yucca plants grow in the southeastern region of America and all through Mexico. Caring for yucca plants outside requires minimal maintenance once planted.
Water newly planted yucca plants well during the first season to establish the root system. Water outside yucca plants only every two to three weeks, during extreme dry periods for the following seasons.
Cut back the flower stalk annually after the flowers bloom in the summer. Cut any dead foliage on the yucca each spring. Wear gloves for protection against the sharp edges of the yucca plant.
Apply fertilizer to the outside yucca plant in the spring. Reapply no more than every one or two years, according to your soil conditions and plant development.
Dig up any offshoots emerging in the area around the parent yucca to control or propagate. Plant the offshoots in other areas to establish new yucca plants.
