Yucca Plant Care

The Yucca plant belongs to the Agavaceae family. It is an evergreen perennial plant. Generally these plants are very hardy and can be planted at almost any time. The yucca plant prefers full sun, though the plant does tolerate light shade. The plant grows well in soil that is extremely porous and drains very well.

In theory the Yucca plant is supposed to be very hardy and well tolerant of many harsh conditions. But, in practice, Yucca plant care can be quite exhausting. The plant does need close attention if it is to grow within the limited and controlled conditions of the home.

The first important step in Yucca plant care is to get complete and good sunlight. This is the natural condition of the plant. If the plant has to remain healthy, it has to be pruned well. If the Yucca plant does not receive enough light and if they are not kept under direct sunlight, then extra maintenance will be needed in the guise of pruning. This is because when light is less, the stem of the plant will stretch towards any source of light.

Yucca plants are not very happy in a pot, but they tolerate very large pots. The potted Yuccas do not get as big as those planted in a bed with free root run. Often the potted plants develop a dwarfish look that is attractive in it own way.

The spineless yucca plant has a sharp and spear like foliage. The leaves are very pointy and sharp. These plants are very durable and can tolerate dry conditions. But over watering the plants will show up as a brown tip on the leaves. If the plants are not getting enough water, they will shrivel up - the stalks become thin and dry and the leaves become yellow and brown. This usually happens to the lower leaves of the plant.

As yuccas age, there is a possibility of the foliage showing random splotches. In this case, the black parts should be trimmed off. If that is not possible, the entire leaf should be removed. In case the entire head becomes unsightly, the splotchy heads should be cut off and the plant should be allowed to grow new ones. It is easy to propagate Yucca from existing canes that are healthy. Too young and too old canes are not very good for propagation. Though Yuccas like more sunlight, deeper foliage is produced when the plants are kept in 40-50% shade. The plants should be fertilized using a slow-release fertilizer. The planting media should support canes, but also must provide good aeration. A peat: sand mixture is ideal as this can support the canes and yet provide good water and fertilizer retention. The media should also include micronutrients and sufficient dolomite. A pH of 5.5 - 6.5 is ideal. Elevating the pH levels may cause iron deficiency.

There are some common symptoms that are observed in yucca plants. If the leaves have necrotic areas at the tips as well as along the margins, the plant could be suffering from fluoride deficiency. The pH of the soil should be increased by adding lime into it. Brown leaf spots indicate fungal infections. Infected, older leaves should be removed immediately. Most yuccas are exposed to rainfall and overhead watering. So, regular application of fungicides is necessary to prevent this condition. The major insect threat to this plant comes from mealybugs, scales, thrips and weevils. Effective use of pesticides will control these.

In spite of the difficulties involved in cultivating this plant, this is a popular favorite among plant lovers. Once the plant gets the right conditions for growth, it survives for a long time, giving off new shoots and growing rapidly.
