What are Yucca Plants

What are Yucca Plants

Yucca plants are part of the Asparagaceae family, including over 40 different sub-cultivars. Native to Mexico and the Caribbean, these hardy plants offer an attractive indoor display and range in size from smaller plants to shrubs to trees. 

Yucca plants are incredibly slow growers, which makes them an ideal option for container growing. More so, as these plants are used to warm, drought conditions, they grow happily indoors without needing too much humidity and moisture.

The only issue with yucca plants is that the foliage can be toxic to pets, such as dogs, cats and even horses. Should you be planning on growing yucca plants with pets, it is perhaps advisable to keep them out of reach or in an area to which your pet does not have access. 

Types of Yucca Plants

Although there is a range of yucca varieties, there are only a few which are well-suited for indoor growing. The most popular chosen cultivars include: 

  • Yucca guatemalensis. Also known as the Spineless Yucca, this variety has a large bulbous base and long, sword-like leaves. This is the most common variety found in homes. 
  • Yucca aloifolia. Also known as the Spanish Bayonet, this variety has long, shard leaves and deep green, variegated foliage. This cultivar is not advisable for homes with children, as the leaves can be hazardous.

In the right conditions, yucca plants are incredibly easy to grow. Before planting, your biggest concern will be ensuring the right kind of soil and sufficient sunlight for your yucca plant to thrive. 

Yucca Plants Sun Requirements

Yucca plants prefer full sun conditions. They tend to thrive most in bright, direct sunlight. However, it can also tolerate bright indirect light. As such, it’s a good idea to keep your yucca plants near a large window.

In insufficient sunlight, your yucca plant will have stunted growth and may lose colour in its leaves.

Don’t worry about finding an overly expensive soil mix. Yucca plants aren’t really fussy. 

Temperature

Yucca plants are used to high heat conditions, which also means that they are used to temperature fluctuations. You can keep these plants in most parts of your home.

Although they enjoy moderate humidity, it is not recommended to keep these plants in the bathroom. 

Propagating Yucca Plants

Propagating Yucca Plants

The most common method of Yucca plants propagation is through the division of offsets, which can be done fairly easily when repotting. As with succulents, yucca plants produce offshoots at the base of the plant. 

When repotting simply:

  • Remove the parent plant from the pot and gentle tousle the roots lose. 
  • Use a sharp blade to remove the side stems which grow off the base. 
  • At the base, you will want to leave a 4 to 5cm stem. 
  • Dip the offsets into a rooting hormone and plant into a porous potting mix. 
  • Keep your cutting in a warm and sunny spot. 
  • Water well without water logging or soaking the soil. 

Potting Yucca Plants

Potting Yucca Plants

Yucca plants are happy being pot bound, and generally grow slowly, and as such only need to be repotted every 2 or 3 years. However, with larger plants repotting can be a tedious task. 

In these instances, it is possible to simply remove the top layer of soil and replace it with fresh soil to replenish. 

Yucca Plants Care Guide

Although these plants thrive off a little bit of neglect, it is important to occasionally water and fertilise your yucca plants to keep them healthy and thriving. Pruning or other care won’t be necessary. 

Watering Yucca Plants

Yucca plants are definitely water sensitive, so when you water your plants, it’s important to regulate how much and how often.

During the spring and summer, you can water your yucca plant regularly, ensuring the soil dries sufficiently in between. During the winter, you can cut back on watering almost altogether. 

Fertilising Yuccas

During the growing phase, it is advisable to support your yucca plant with a little bit of fertiliser. A slow-release, granular fertiliser or liquid fertiliser is ideal. Fertilisation can be done as much as once per month.
