Yucca Plant Care Guide: How to Grow Yucca Plants

Yucca plant is the common name for some plants within the Yucca genus of drought-tolerant trees, plants, and shrubs, which belong to the Asparagaceae family. Native to Mexico, yucca plants feature rosettes of green leaves and white flowers. The yucca plant depends on the yucca moth, its main pollinator. Yucca flowers need the yucca moth for pollination because they are unable to self-pollinate. In their natural environment, yucca plants produce flower stalks that grow up to ten feet in height, produce waxy white flowers, and attract yucca moths.

Outdoors, yucca plants do best in USDA hardiness zones five through eleven. You may also grow some species of yucca plants indoors, but the bell-shaped flowers usually grow in outdoor growth mediums only. Be aware of the toxicity of the yucca plant, which is poisonous to pets and humans if consumed.

Consider the two most common species of indoor yucca plants.

1. 1. Spanish bayonet: Spanish bayonet (Yucca aloifolia) features stiff, pointy leaves that can grow nearly two feet in length. Native to several southern parts of the US, Mexico’s Yucatán coast, and areas of the Caribbean, the Spanish bayonet yucca plant does best in a warm, arid environment.
2. 2. Spineless yucca: Also known as yucca cane (Yucca guatemalensis or Yucca elephantipes), this species is considered a giant variety. Spineless yucca can grow up to forty feet tall in its natural habitat. When grown indoors, however, this plant takes several years to grow up to five feet in height. In the right conditions, it displays cream-colored flowers.

Consider some common species of outdoor yucca plants.

1. 1. Joshua tree: Reaching up to seventy feet in height in their natural habitat, Joshua trees (Yucca brevifolia) are the tallest of the yuccas yet have surprisingly short leaves.
2. 2. Banana yucca: Dried, bluish leaves characterize the banana yucca plant (Yucca baccata), which produces seed pods that resemble bananas and large flowers resembling peeled bananas.
3. 3. Beaked yucca: Fluffy in appearance, the beaked yucca plant (Yucca rostrata) is deceptively sharp and blooms with white and purple flowers. Another slow-growing plant, beaked yucca can take ten years to mature fully.
4. 4. Soaptree yucca: Growing up to twenty feet tall, the soaptree yucca (Yucca elata) has thin, filament-like needles.
5. 5. Spanish dagger: Spanish dagger (Yucca gloriosa) is a frost-tolerant evergreen shrub that is native to the southeastern US and commonly used for landscaping purposes.
6. 6. Adam’s needle: Adam’s needle yucca plants (Yucca flaccida) grow relatively low to the ground and make great additions to rock gardens.

The best place to plant your yucca plant is in a spot that receives full sun. Whether you grow your yucca plant indoors or outdoors, these succulents thrive on plenty of bright light. Choose a west- or south-facing window for your indoor yucca plants so that they are exposed to plenty of sunlight. In the summer, yucca plants can do well on sunlit patios, but be sure to bring your yuccas inside on chilly nights. Yucca plants thrive in hot, dry climates, so avoid exposing these plants to excessive cold or humidity. Due to these plants’ sharp leaves, you’ll also want to keep them away from children and pets.

Caring for your indoor yucca plants requires a few simple strategies.

1. 1. Soil: Choose a nutrient-rich potting soil that drains well. The yucca plant grows well in most soil conditions, but neutral to acidic soil with a sandy texture is ideal.
2. 2. Watering: Avoid overwatering by watering your yucca plants only when the top layer of soil feels dry to the touch. Adequate moisture is important, but too much water can lead to root rot.
3. 3. Pruning: Early spring is the best time to prune your yucca plants. Clear away any overgrowth before the growing season of spring and summer begins.
4. 4. Fertilizing: Outdoor yuccas need minimal feeding, but fertilizing your yucca houseplants is helpful. Use a balanced liquid fertilizer once per month during the growing season.
5. 5. Pests: Agave plant bugs and mites sometimes infest yucca plants. Apply a gentle insecticide soap with neem oil to eliminate pest problems. Avoid letting water collect at the base of the plant to prevent fungal infections.
6. 6. Propagation: Locate the rhizomes, or thick underground roots, to propagate your yucca. Use a clean, sharp knife to break off the offsets from the rhizomes. Apply a rooting hormone to the stem cuttings. Plant them in potting soil in a bright location with indirect light. New roots will start to grow within a few weeks.
