Yucca filifera

St. Peter's palm flourishes in dry conditions and needs only occasional watering. During the fall and winter, water it every 2 to 3 weeks, and in the spring and summer, water it weekly. Be sure to let the soil dry out before each watering. If the plant is outdoors in direct sunlight, you may need to water it more frequently. Over-watering can cause the tips of the leaves to turn brown and lead to root rot, whereas under-watering results in brown, wilted leaves.

Native to dry areas, St. Peter's palm does best in full sun, as its natural habitat has intense sunlight and little shade. It can also tolerate partial sun, providing some flexibility in its growth.

St. Peter's palm does best in warm conditions and needs elevated temperatures during the growing season to encourage growth and metabolic activity. It prefers plenty of sunlight, appropriate moisture, and good air circulation. It can be harmed by excessively low temperatures and by too much watering. It's important to maintain a balance and avoid very high temperatures or excessively dry conditions as well.

St. Peter's palm only requires light applications of fertilizer 1-2 times a year during the growing season. Do not fertilize in winter or in summer when the plant is dormant. Cut back on fertilizer for repotted plants and wait a couple of months after repotting before applying any. Fertilizing helps maintain healthy growth and encourages blooms.

St. Peter's palm is characterized by its sword-like leaves and sturdy trunk. To promote its growth, it's best to prune it in early spring. During this time, remove any dead leaves and crowded stems, making sure to use sharp tools for clean cuts. Pruning not only encourages new growth but also improves airflow and reduces pest problems. This results in a healthier and more attractive plant.
