Sir Grange Zoysia Turf Installation

During the summer months, Australia's weather can be hot and harsh. The winter months are cold and freezing. Even though turf can be installed during the spring, the best time to do so is in Autumn.

When you lay turf in the Autumn, the grass is still growing, and the temperatures are cooler. This helps eliminate heat stress and improve the survivability rate.

It also provides the grass the time it needs to develop before summer. If you live in South-East Queensland, you can install turf all year round.

Ground Preparation

Before you can install turf, the surface area needs to be prepped. It is crucial you get rid of all the weeds and grass before preparing the soil. To kill the weeds/grass, use a broad-spectrum systemic herbicide.

When using any type of herbicide, make sure to read the instructions thoroughly. You will need to properly mix the herbicide, and you will also need to wear the appropriate personal protective equipment.

Here is our review on the best weed killers on the market to help you decide which would best work for your garden. After application of the herbicide, wait for at least 7 to 10 days. If there are still weeds and grass present, apply a second coat.

If you have an existing lawn that needs to be removed, you might need to remove the existing turf with a turf. Or you can also use a rotary hoe (which is available to hire).

Once the existing turf is removed, the area needs to be cultivated. To do this, you will need to remove any stones or other debris while digging out to a depth of 150 mm.

Adding Fresh Soil

Having fresh soil is crucial for having a healthy lawn. You do not have to wait to install fresh soil. When spreading out soil, you will often want to lay it 100 mm deep. Sometimes this may not be possible. It will all depend on the site itself.

You will need to do a little math to determine how much soil you will need. To determine how much soil to bring in, figure 2m³ of soil for every 20m² of turf area.

After installing the soil, level it out with a rake. The soil should sit 75 mm below weep holes to comply with building regulations. We recommend placing sandy loam soil under your new turf. It is great soil that allows for drainage and permits the roots to grow deep. 

This, in turn, leads to a more drought tolerant lawn. The better the dirt foundation you lay, the better your result will be.

Planning the Space

When planning for new turf, sketch out the area. This will give you the ability to see exactly what you are looking at. Make sure to get the exact measurements since these are critical.

Once you have the area sketch up, you can easily calculate how much herbicide, dirt, and turf you will need,

Handling and Laying Sir Grange Zoysia

Handling and Laying the Turf

Now that you have the area prepped and ready for turf, it is time to lay it. Turf is harvested in rolls or slabs. The turf is flexible yet extremely heavy. We recommend that you fold it to make it easier to handle.

This will help prevent the pieces from breaking apart, and it will be easier for you to carry. Start laying the turf around the perimeter of the area. Do this by unfolding or unrolling one large piece. Continue working your way around the perimeter.

You do not want to use small pieces around the perimeter unless absolutely necessary. Smaller pieces are susceptible to drying out and dying.  After you have the perimeter laid, work your way strip by strip from the longest run.

Lay each strip against the other. They should touch each other without leaving a gap or overlapping. Be careful not to pull on the turf and stretch it. If you have any pieces that are overlapping, use a sharp knife to cut off the overlapping area.

Stay Off the Lawn

Once the new turf is laid, you will want to stay off it for 2 to 3 weeks. If you walk on the turf too early, you can damage the roots and disturb the rooting process.
