Yucca

Belonging to the Liliaceae family, Yucca is one of the most popular houseplants because it is easy to grow and is very beautiful and decorative. It is a plant that can be recognized simply by observing its woody trunk, it produces small flowers gathered in panicle inflorescences. These grow on stems that arise in the center of the plant. The Yucca originates in the West Indies and in America, in nature it can reach 15 meters in height while cultivated in pots it does not exceed two meters in height. This genus includes about forty species but the most common are the Yucca Aloifolia, the Yucca Elephantipes, the Yucca Brevifolia and the Yucca Rostrata. Yucca Aloifolia has South American origins and a plant that does not exceed one and a half meters in height. Its leaves are gathered in clumps, they are thick and have an intense green color. They are pointed and have slightly serrated edges. Yucca Elephantipes is native to Mexico and Guatemala, grown in the open air they reach 15 meters in height, while in pots they do not exceed two meters. Its leaves are glossy green and somewhat pointed. Its flowers, on the other hand, are creamy white. Yucca Brevifolia, named after its very short leaves, is native to America. It has a very compact crown, in fact the birds use it to create their nests. Yucca Rostrata originates in areas of Texas and Mexico. grown in the open air, they reach 15 meters in height, while in pots they do not exceed two meters. Its leaves are glossy green and somewhat pointed. Its flowers, on the other hand, are creamy white. Yucca Brevifolia, named after its very short leaves, is native to America.

Cultivation


Yucca is a plant that does not prefer particular temperatures, in the summer it grows very well even at 25 ° C as long as fresh air circulates in the environment in which it is placed, in winter it is recommended not to place it in places where the temperature drops below of 10 ° C. It is a plant that likes to be exposed to direct sunlight, in the warm months it is preferable to transfer it to outdoor places in order to favor flowering. As for watering, the Yucca should be watered abundantly in the spring and summer, while in the colder periods watering should be reduced. It is advisable to be careful in the period of abundant watering, water stagnation causes damage to the plant. In our areas, it is very rare for a Yucca to flower indoors. Yucca is a plant that should not be pruned, the only attention to be paid to it is to eliminate the now dry leaves and the damaged parts that may be the cause of parasitic diseases. Tools that are used to remove damaged parts must be flame cleaned and disinfected to avoid infection.

Soil and fertilizer

This type of plant should be repotted every year in spring using a peat-based soil. Yucca is a plant that needs a lot of space to host its roots and therefore repotting is important because, as it grows, the pot in which the plant is placed becomes smaller and smaller. Like all plants, even the Yucca must be fertilized to help it in its development. The fertilizer to be used is a liquid fertilizer that will be diluted in the water used for watering. The fertilizations must be done every 30 days from April to October, for the rest of the months of the year the fertilizations must be suspended. For all green plants, and therefore also for Yucca, it is recommended to use fertilizer with a high level of nitrogen. Furthermore, the fertilizer must not only contain nitrogen, Phosphorus and Potassium but it must be rich in Iron, Zinc, Copper, Manganese, Molybdenum and Boron. These substances are useful for promoting correct and balanced growth of the seedling.

Diseases and parasites

If we do not pay due attention to our plants, we risk making them sick and exposing them to pest attacks. The yucca needs a lot of light for its growth, bad lighting could lead the leaves to a pale green color and, in the event that no action is taken immediately, there is a risk of spreading the disease on the whole plant. One solution would be to move the plant and place it in a brighter place that suits its needs. If observing the plant we realize that its posture is stunted, it means that the plant is watered excessively. A remedy would be to be more careful not to overflow with water and not to leave too much water in the saucer. As far as the parasites that can affect the plant are concerned, we have the Cochineals and in particular the brown and floury ones. Brown cochineals carry brown spots on the underside of the leaves, while mealy cochineals lead to the formation of a substance similar to flour. Both can be removed by rubbing the leaf with a cotton swab dipped in alcohol. Or it is possible to remove these parasites by “washing” the plant with soap and water, the important thing is to rinse the plant thoroughly. In the event that it is a question of larger plants or the situation is more serious than previously thought, we proceed by administering specific pesticides to the plant. while floury cochineals lead to the formation of a substance similar to flour.
