Grass trees are relatively easy to care for and dislike constant watering.

The most common reason for grass trees to die is too much or too little water. This can be from either too little rainfall or from irrigation systems not working properly. They are susceptible to pollution and all manner of environmental stresses.

What are grass trees?

Grass trees are native to Australia. They are also known as Xanthorrhoea, and their scientific name is Xanthorrhoea Preissii. Grass trees can grow to be up to 15 metres tall and they have long, slender leaves that are green in colour. The trunk of a grass tree is usually black in colour, and it is covered in a thick layer of bark that may look like a black skirt. The flowers of a grass tree are white in colour and they grow in clusters at the top of the tree. Grass trees are found in open woodlands, heathlands and scrublands. The Royal Botanic Garden Sydney has some great information on grass trees.

How do you care for a grass tree?

Grass trees are relatively easy to care for and dislike constant watering. They prefer well-drained soil. Grass trees need to be watered regularly, especially during the summer months to help the plant and encourage root growth. They should be fertilised annually with native plant fertiliser. It's best to regularly remove dead foliage and dead leaves to control scale and sooty mould and ensure the plant grows naturally. They look great in a landscape setting with trees and shrubs.

What are the benefits of grass trees?

Grass trees have a number of benefits in a home garden. They are drought tolerant and can help to stabilise the soil in areas that are prone to erosion. Grass trees also provide food and shelter for a variety of native animals. The nectar from the flowers of a grass tree is a favourite food source for birds. The bark of the grass tree and the green foliage are used by animals to build their homes. Grass trees are an important part of the landscape in Western Australia and they play a vital role in the ecology of our country.

Are grass trees drought-resistant?

Yes, grass trees are drought resistant and they don't like areas with insufficient drainage. Grass trees are also able to tolerate poor-quality soil, extended hot weather and consistent watering.

Do grass trees need a lot of water?

No, grass trees do not need a lot of water, but they will need to be watered more frequently during the summer months.

Can grass trees be grown in pots?

Yes, but they will need to be watered more frequently, as the roots will not have access to as much water. It is also important to use a well-draining potting mix, as grass trees do not like to sit in wet soil.

Are grass trees native to Australia?

Yes, grass trees are native to Australia. They are found in all states and territories except for the Northern Territory.

There are two species of common grass tree: Xanthorrhoea minor and Xanthorrhoea australis. Xanthorrhoea minor is the smaller of the two, growing to a height of around 2 metres. Xanthorrhoea australis can grow up to 10 metres tall.

Grass trees have thick trunks. Their flowers are white or cream-coloured and they produce black fruit. Some have a flower spike poking up and if planted near fruit trees, may help keep birds like cockatoos at bay.

The nectar from their flowers is also a favourite of birds and bees.

Grass trees play an important role in the ecology of Australia's bushland. They help to stabilise the soil and provide shelter.

What are the alternatives to planting grass trees?

Some other native Australian plants that can be used include acacias, eucalypts, banksias, melaleucas and hakeas. These plants all have different requirements in terms of soil type and climate, so it's important to choose the right ones for your area.

Are grass trees a fire hazard?

Grass trees are not a fire hazard. In fact, they can help to prevent bushfires from spreading. This is because their thick trunks and leaves act as a barrier to the flames. However, grass trees must be well-watered during fire season. If they become too dry, they can catch fire and burn readily.

How do I know if my grass tree is thirsty?

If your grass tree is looking wilted or its leaves are drooping, then it's time to give it a good drink. Always check the soil before watering.

How often should I water my grass tree?

Grass trees should be watered every one to two weeks. They can be watered less frequently in winter when they are dormant.

What type of soil do grass trees like?

Grass trees prefer well-drained soil that is high in organic matter. If your soil is heavy or compacted, try adding sand or grit.

How long will a grass tree live?

Grass trees can live for hundreds of years.

How do I propagate a grass tree?

Grass trees can be propagated from seed or by division. To grow from seed, sow the seeds in spring or summer in a well-drained seed-raising mix. Keep the soil moist and place the pot in a warm, sunny spot. Water regularly and fertilise monthly with native plant food. Division is the quickest and easiest way to propagate grass trees. Choose a healthy plant that has several offsets. Using a sharp spade, carefully divide the offsets from the main plant. Transplant each offset into its own pot filled with dirt. Water regularly and fertilise monthly with native plant food.

What are the pests and diseases that affect grass trees?

Grass trees can sometimes be affected by scale insects, mealybugs or caterpillars. These can be controlled with an oil-based spray such as white oil.
