Perth, the sunniest capital city in Australia, enjoys an average of nearly nine hours of sunshine each day throughout the year. This abundant sunlight provides a golden opportunity for gardening aficionados to harbour dreams of growing vibrant, lush green lawns around their homes.

The problem is that Perth’s soil is predominantly sandy, making lush lawns an elusive goal for many gardeners despite the sunshine. That’s because sand’s porous nature makes water and nutrients drain away too fast, hindering the growth of healthy natural grass.

As a result, artificial grass in Perth has become popular for many homeowners and commercial operators, as it’s far easier to maintain than natural grass on sandy soil. Fortunately, there are effective strategies for growing and maintaining a natural lawn in Perth’s sandy soil. It will take some effort, but it’s definitely achievable!

Understanding Perth’s Sandy Soil

The first step in cultivating a lush lawn in Perth is to understand the local soil, which is very sandy, characterised by large particles and a loose structure. This structure makes it highly permeable, allowing water and fertilisers to wash away more quickly than in denser, clay-rich soils. This leaves the grass dry and starved of nutrients.

Preparing Your Soil

To successfully grow natural grass in sandy conditions, you need to improve the soil. Here are three key factors that make growing a natural lawn much easier on sandy soils.

  1. Drainage: Although sandy soil drains well, it can lead to drought conditions in your lawn during dry periods. Consider installing subsurface drainage systems, contouring the landscape, or creating raised beds to better control the flow of water.
  2. Water Holding Capacity: You’ll need to mix in plenty of organic matter like compost or peat moss, which helps retain moisture and enhances the structure of your soil.
  3. Nutrient Holding Capacity: Similarly, to improve the retention of nutrients, you’ll need to add organic matter to your soil.

Selecting the Right Grass

Choosing the right type of grass is also important because some grass species are better adapted to sandy conditions than others. For example, Buffalo, Zoysia and Kikuyu grasses are known for their vigorous growth and tolerance to heat and sandy soils, making them ideal for Perth’s climate and sandy soil.

Regular Maintenance

Maintaining a lawn in sandy soil requires regular care and attention. This includes watering, fertilising, weeding, mowing and aeration.

  • Watering: To reduce the amount of water that drains away and is wasted in sandy soil, water your lawns more frequently than usual, but cut back on the volume of water.
  • Fertilising: Regular feeding compensates for the nutrients that leach out of sandy soil. Use a slow-release fertiliser that provides a steady supply of nutrients over time.
  • Weeding: Weeds are a problem in sandy soils, competing for limited nutrients and water. This means that regular weeding is essential for lawns grown on sandy soils.
  • Mowing: To keep your new lawn healthy, you’ll need to mow regularly. This encourages dense growth, which, in turn, helps prevent the growth of weeds.
  • Aeration: Periodic aeration helps improve the exchange of air between the soil and atmosphere, encouraging deeper root growth and better penetration of water and nutrients.
