Yucca plants are associated with desert climates, requiring little water and thriving in hot conditions. Yucca can also thrive even in wetter climates, as long as the soil is well-drained. These hardy plants add ornamental value to the yard. Not only are their long, spear-shaped leaves evergreen, yuccas also produce a multitude of white flowers on tall flowers stalks. Caring properly for the yucca and flower stalk encourages it to bloom year after year.
Water yucca only in the first year after planting it. Irrigate once every two to three weeks, moistening the soil to a 6-inch depth. Established yucca require no additional irrigation, and too much water can cause plants to lose their leaves or flowers prematurely.
Trim off the yucca stalk once it finishes its blooming cycle and all the flowers have wilted. Or leave the stalk in place for winter interest and prune it off in early spring before the yucca begins actively growing again. Cut the stalk off 3 to 4 inches from the base of the plant, using a sharp pair of pruning shears.
Remove any damaged or diseased leaves, which are unattractive and may spread disease to the rest of the plant and affect flowering. Tear the leaves off by pulling them to one side, or trim them off with a pair of shears at the spot where they emerge from the trunk.
Mulch around the yucca each spring with a fresh 2-inch layer of compost. Compost adds some nutrients to the soil while the organic matter in it aids soil drainage. Improved soil drainage prevents water damage to the yucca, ensuring it is able to bloom well each year.
