How to grow yucca

Yuccas do best in bright light and can cope with some direct sunshine. Water only when the top few centimetres of the soil are dry. Yuccas are tolerant of drought.

Where to grow yucca

Yuccas are one of the least fussy plants you can grow. Ideally, grow it in a warm room where the temperature won’t fall below 7°C. It can cope with some direct sunlight.

How to plant yucca

Place your yucca plant in soil-based compost, with some horticultural sand or grit added for good drainage. Repot every two or three years. Use a sturdy pot to avoid the plant becoming top heavy and toppling over as it grows.

Yucca plant care

You’re more likely to kill a yucca plant by watering it too much than too little. Water when the top few centimetres of compost have dried out, but don’t worry if the soil dries out completely from time to time – yuccas are tolerant of drought. Allow any excess water to drain away. Water more sparingly in winter.

Feed every couple of months with half-strength liquid fertiliser from spring to autumn. Yuccas don’t require high humidity so you won't need to mist it. Wipe the leaves occasionally to keep the leaves free of dust.

Yuccas do well when slightly pot bound, so they don’t need repotting very often – every two or three years in spring is fine. It can be hard to repot a mature yucca due its unwieldy shape – in that case, remove as much compost from the surface as you can using a trowel and top up with fresh compost.

If your plant becomes too big, just cut the trunk down to the height that you want – it may look unsightly for a while, but it should soon re-sprout. You could repot the chunk that you have cut off to propagate it as a new house plant.

How to propagate yucca

The easiest way to propagate a yucca plant is from the offsets (pups) at the base of the trunk. You could do this when you repot the plant in spring. Simply cut off an offset using a sharp knife. Allow the wound to dry out for a few days, then transfer the new plant into a new pot and water well. Keep in a warm spot.

You can also propagate yuccas from 20cm stem cuttings in spring, in a similar way to dracaenas. See the link below for more information.

You can also grow yuccas from seed.

Growing yucca plants: problem solving

Yellow leaves Yellowing is normal on lower leaves – they will die back and fall naturally, giving the plant a palm-like appearance over time. You can gently pull off the leaves or cut them off. If there are yellow leaves all over the plant, you will have either overwatered it or not given it enough water.

Brown or black spots on the foliage This is leaf spot, caused by bacteria or fungi. Remove any affected leaves and treat with an organic fungicide.

Brown leaf tips This is usually due to erratic watering. You can cut these off, but don't cut into green growth, otherwise they'll reappear.

Sagging, droopy leaves This is a result of underwatering.

Pale leaves Too much shade causes leaves to turn pale.

Rotting stems This is due to overwatering and is more likely to happen in winter. Yuccas do not enjoy sitting in cold, wet compost, so reduce watering. If the problem has spread too far, you may not be able to save the plant.

Mealybugs You may find insects that look like white, fluffy blobs. These are mealybugs and are usually found on the undersides of leaves. Wipe them off with a damp cloth or cotton bud that has been soaked in an insecticide that contains fatty acids or plant oils. Keep checking the leaves, as mealybugs can be hard to eradicate.

Scale insects You may also spot scale insects, which are small, brown, sap-sucking insects that are around 6mm long. Wipe them off with a cotton bud or cloth soaked with an insecticide containing fatty acids.

Yucca aloifolia is also known as the Spanish bayonet. As its name suggests, the leaves have very sharp points. Keep them away from young children and away from eye level.
