Yucca aloifolia, commonly known as Spanish bayonet, is part of the agave family of shrubs, and makes a striking addition to most landscapes. Its dark green leaves form sharp spikes that protrude from thick, upward-growing trunks. During the spring and summer months, there are often white flowers in the middle of the plant. It is very easy to grow yucca aloifolia, particularly in warm climates.
Gardeners have success growing yucca aloifolia in partial shade or partial sunlight, yet the plant will also thrive in areas that receive full sunlight. It can tolerate a wide variety of soil types from sandy to acidic to alkaline and even loamy. It will tolerate salty soil, as well, making it ideal for coastal areas. It is perfect for areas that do not receive much rain because it has a high tolerance for drought. In addition, its high drought tolerance means that gardeners do not need to water frequently.
When planting yucca aloifolia, space the seedling 12 to 15 feet (3.6 to 4.7 m) apart. This will give its roots, leaves, and trunk plenty of room to grow and the spacing will prevent one plant from blocking another from the sun. It is hardy shrub; consequently, it can grow in temperatures ranging anywhere from five degrees Fahrenheit (-14.9 degrees Celsius) to those well above 40 degrees Fahrenheit (4.5 degrees Celsius).
Many gardeners wonder how to propagate yucca aloifolia. One method is to divide the rootball. Doing so creates separate plants that can be sown immediately. If starting from seeds, it is best to sow the seeds indoors initially. This should be done before the last frost occurs, so the seeds have a chance to grow into seedlings that can be planted outside. In the alternative, seeds can also be sown directly into the landscaping, if the last frost of the season has already occurred.
Oftentimes, people do not want to spend money to purchase seeds from the store, especially if they already own several yucca aloifolia plants. In those cases, it is possible to use the seed from the pre-existing plants. Simply collect the seed pods after they have dried on the plant. Then, break the pods open and collect the seeds. The seeds should be cleaned and then can be stored for future use.
Those wanting to grow yucca aloifolia should be aware of any potential pests. Although there are not any serious pests, it can be susceptible to leaf spot in areas with poor air circulation. In addition, yucca moth larvae can be a problem. The larvae eat through the shoot, causing it to weaken and die. However, the problem can be prevented with pesticides.
