Windbreak: Planting and Tree Selection

The beauty of it is that we truly have an incredible selection of native and exotic flora throughout Australia that is perfectly suited for screening and wind deflection. Plants with inherent strength are ideal and you can choose between many stunning species of trees, shrubs, and even hedges.

Whether you live out in the country or a residential house like me, many different types of landscapes can benefit from some form of wind protection. 

In this article, I will be sharing 20 of the best windbreak plants to grow in Australia in the hopes I can help you find the perfect fit for your property. I will be highlighting my top 10 native species as well as my top 10 introduced species to give you as much of a selection as possible. Let’s begin.

What is a Windbreak?

Put plainly, a windbreak is a row or screen of plants that function to protect sections of a garden or landscape from strong winds, simultaneously sheltering other plants as well. A windbreak can be effective in many forms – whether a succession of trees or a bushy and shrubby hedge.

Sure, a windbreak’s main purpose is to deflect air movements around your home and garden, but if you’re anything like me, aesthetics are also a crucial component to my decision-making when selecting which plants to establish in my outdoor environment. 

To this end, I will also be highlighting the ornamental qualities of the species below for those interested in distinctive foliage and colourful flowers. 

Benefits of Planting a Windbreak

• Helps to guide wind over and around the vital structures and sections of your property that you want to protect.
• Lessens the impact of direct prevailing winds or intense consistent winds on existing vegetation, essentially ensuring their wellbeing.
• Boosts the privacy of your property by making it more difficult for neighbours to look around. 
• Apart from wind protection, a windbreak can also elevate a property's overall aesthetic appeal using attractive foliage and vibrant blooms. 
• Adds additional sun protection to properties.
• Will attract local wildlife, big and small, further contributing to the biodiversity and health of your area’s ecosystem.
• Helps to control soil erosion and protect wind-sensitive crops, which will typically lead to increased yields.
• Helps to save water as moisture retention in the soil is boosted by the protection from strong, hot winds. 

Key Factors of a Good Windbreak

Whether you choose to plant windbreak trees or windbreak shrubs, there are some key components to these leafy shields that will ensure they fulfil their purpose as best they can. 

• Ideally, for larger landscapes, a windbreak should consist of a mixture of tall and medium-height trees, with lower-level shrubs and some understory of native grasses. This will ensure both height and density are achieved.
• A layered or grouped planting approach is recommended with a few species suited to your area. 
• I tend to lean towards evergreen specimens when considering windbreaks as these plants maintain denser foliage throughout the year, allowing the windbreak to function for longer periods, even in dry and cold winters. 
• A mixture of various heights and dense foliage is crucial. 
• For larger properties with intense winds, is it best to establish fast-growing windbreak trees that reach at least 8 metres or more in height with thick foliage and a low-branching habit. 
• For smaller gardens and properties, a solid hedge or a row of small trees would work perfectly. 
• In general, fast-growing plants are always best for windbreaks as their more vigorous growth allows them to protect areas at a faster rate.

Tips for Planting a Windbreak

• For larger trees, I recommend spacing them at least 5 to 10 metres apart when selecting your planting sites. Younger specimens may need to be staked for additional support until established. (Read our guide on plant staking for more details.) 
• For shrubs and smaller specimens, a plant spacing of 2 to 3 metres will suffice. 
• For privacy purposes, it is best to plant along your main fence lines. 
• Plant no less than 2 rows of windbreak trees on larger properties and 1 thick row in smaller gardens. 
• Whether native or introduced, select plants that suit the temperature and climate of your area. 
• A windbreak will typically protect a distance from 2 to 10 times its height, meaning a 5-metre-high windbreak would shelter a distance of up to 50 metres away. 
• For optimal effectiveness, orientation is also vital. Be sure to orientate your windbreak as close to perpendicular to the prevailing winds as you can. Meaning that the prevailing winds should come at about a 90-degree angle for the most part. 
• If you’re unsure which direction your prevailing winds come from, just have a look at established trees around your area, they will normally grow and lean away from these winds. 

Important Considerations When Planting a Windbreak

Before planting your windbreak, be sure to consider the areas you want to shelter, the topography of your property, and the direction of the prevailing winds as they cause the most damage. 

It is important to consider spacing from structures and other buildings or paving if you intend to plant a large tree. 

I would also recommend checking with your local municipality if you intend to grow exotic plants or natives that aren’t usually found in your area. This would mainly be to make sure they cause no unwanted damage to local flora and fauna. 

Lastly, I would like to emphasise the importance of growing a few different species in your windbreak. This will vastly limit the spread of possible pests and diseases between species, as well as offer a more textured and architectural appeal to your landscape.

Frequently Asked Questions About Windbreaks

What is the best kind of windbreak?

The best kind of windbreak would include a good mix of height and density. This means planting both tall and medium-height trees with some lower-level shrubbery and some understory.

Typically, evergreen plants are preferred as well as conifers and other specimens with a dense growth habit.

What is the fastest growing windbreak?

This would largely depend on your area, climate, and landscape. For fast-growing windbreak trees and shrubs, I usually recommend choosing plants that are endemic to your environment.

So native plants that are suited to the specific climate conditions of your area. 

What is the best windbreak for a house?

The best windbreak for a residential house should block winds close to the ground. Use low-growing trees and shrubs with dense foliage to ensure optimal wind protection. Be sure to also prioritise planting along the fence most perpendicular to the prevailing winds in your area. 

What is the best hedge for wind protection?

We have an abundance of native Australian hedge plants to choose from. These plants would offer ideal wind protection as they are fast-growing, suited to our climates, and can usually be pruned for denser foliage and growth to the ground level. 

What Australian shrubs are wind tolerant?

There are many spectacular wind-tolerant Australian shrubs. The most popular are bottlebrushes, banksias, and coastal rosemary. 

How wide should a windbreak be?

I recommend planting at least 2 rows of plants, spaced 2 to 5 metres apart depending on their mature sizes. Regarding the length, a windbreak should ideally exceed the height by about 10 to 1. 

How should you position a windbreak?

Is it essential that a windbreak faces the prevailing winds in your area. So, aim to plant your windbreak as perpendicular (90 degrees) to the prevailing winds as possible. 

Can trees grow strong in the wind?

This would largely depend on the species, but yes, trees can grow stronger in the wind. Windbreak trees specifically can adapt their root systems and produce more protective top growth if they are subject to frequent winds and poor weather.

I would endorse staking young trees to ensure proper growth until they mature.
