Yucca plants provide a bold and stunning accent to any landscaping. The plants foliage looks like mighty swords erupting from the ground. Since the plants can grow to 8 feet tall and 3 feet wide, it needs an area free from other bushes or plants that could impede its growth. The foliage is sharp so care must be taken when pruning or watering the yucca plant. With proper treatment, your outdoor yucca plant provides many years of landscaping beauty.
Plant outdoor yucca plants in full sun with proper drainage. Keep the plants at least 3 to 4 feet away from sidewalks or walkways as the sharp leaves can cut a person's skin.
Cut dead leaves from the yucca plant with pruning shears. Normally the dead leaves appear in early spring, but you can prune dead leaves any time of the year. When the flower blooms die in late summer or fall, cut the stalk down to the ground. Wear garden gloves and use pruning shears with handling the yucca plant.
Water new outside yucca plants once or twice a week during their first year of growth to help establish their root system. Water once every two weeks after the first year as the yucca plant withstands drought conditions.
Spray herbicide in the soil around the yucca plants to keep young yucca plants from growing too close to the main plant.
