Basic Yucca Care
Most yucca plants are low maintenance plants and relatively easy to care for. Just like most succulents, they are hardy plants that require little attention and can survive in more unfavourable growing conditions than most other plants. However, some basic care needs should be met for them to thrive relatively well.
- Soil: Yucca plants can grow in most soil types as long as the soil has good drainage. Acidic, neutral, or alkaline soil is ideal for the plant.
- Light: Indirect or dappled sunlight is ideal for yucca plants because full exposure to the sun can hurt the leaves.
- Water: Yucca plants have average to low water needs. Simply water your plant when the topsoil is at least 50% dry. Avoid overwatering because it can quickly cause root rot.
- Pruning: You don’t have to prune your yucca plants except to remove dead leaves and cut off expired flower stalks.
- Fertiliser: For indoor plants, feed your plant with a liquid fertiliser once a month.
- Winter protection: Over-winter container plants by moving them indoors.
- Insects and diseases: They are not prone to problems but insects such as aphids can be present and diseases like root rot occur in the case of overwatering.
- Temperature and humidity: No extra humidity is required but occasional misting of the leaves will be helpful. Temperature levels of 18 to 23 degrees Celsius are ideal
How Hardy Are Yucca Plants
Yucca plants are generally hardy perennials though some are hardier than others. Most will tolerate poor soils regardless of the acidity, do not need much water, and remain green all year round.
For indoor and container yucca plants, you don’t have to bother about their hardiness since they can be protected from frost. For outdoor yucca plants, you have to carefully choose yucca plants that can survive harsh winters in the UK. Yucca plants that are hardy in the UK include:
- Yucca gloriosa – Frost hardiness of -15 degrees Celsius.
- Yucca filamentosa – Frost hardiness of -15 degrees Celsius.
- Yucca recurvifolia – Although not readily available in the UK, it can tolerate temperatures of -15 degrees Celsius.
- Yucca recurvifolia 'Monca' – Also known as Banana Split can tolerate temperatures of -20 degrees Celsius.
