Key Takeaways

• Queensland Blue Couch is a drought-tolerant, low-maintenance grass with a blue-green hue, ideal for Australian gardens.
• It has a creeping growth habit and forms a dense, thick lawn, making it great for ground cover.
• Queensland Blue Couch thrives with moderate watering, regular mowing, and occasional fertilising.

What is Queensland Blue Couch?

Queensland Blue Couch is a fine-leaved, warm-season grass that thrives in full sun and is well-known for its drought tolerance. 

The grass is often sought after for its ability to withstand high temperatures and water restrictions, making it ideal for Australian gardens, especially in Queensland, New South Wales, and Northern Territory.

It gets its name from the bluish-greyish hue that the grass takes on during cooler months, although its colour can shift slightly depending on the time of year and environmental conditions.

Key Features to Identify Queensland Blue Couch

To correctly identify Queensland Blue Couch in your garden or while shopping for turf, here are the main characteristics you should look for:

Distinctive Blue-Green Colour

The most prominent feature of Queensland Blue Couch is its blue-green colour, which can range from a soft greyish-blue to a deep green, depending on the time of year and sunlight exposure. 

During cooler months or in the shade, the grass tends to take on more of a blue hue. 

However, in warmer months with plenty of sunlight, it can transition to a more greenish tone, making it stand out from other types of grass that have a standard green appearance.

Fine, Narrow Leaves

Queensland Blue Couch has fine-leaved grass that is narrower than many other turf varieties. 

The blades of grass are usually around 2-5mm wide and have a soft, smooth texture that feels pleasant underfoot. 

These narrow blades are particularly resistant to wear and tear, making them ideal for lawns that get moderate traffic, such as around patios or garden beds.

Creeping Growth Habit

Like many warm-season grasses, Queensland Blue Couch has a creeping growth habit. 

This means it spreads by stolons (above-ground runners) and rhizomes (underground stems), allowing it to cover large areas quickly and efficiently. 

Over time, Queensland Blue Couch will naturally fill in spaces and gaps, creating a lush, even lawn that requires minimal intervention.

Thick, Dense Turf

Queensland Blue Couch forms a dense, thick turf that is well-suited for creating lush lawns. 

The dense coverage means that the grass can naturally suppress weeds, reducing the need for constant weeding or lawn care. 

This makes it an excellent choice for homeowners in Queensland or New South Wales, where weed issues can be common due to the warm, humid climate.

In addition to suppressing weeds, the thick, dense turf provides great ground cover and reduces soil erosion. 

How to Maintain Queensland Blue Couch

Once you’ve correctly identified Queensland Blue Couch, it’s important to know how to care for it to ensure it remains healthy and vibrant. 

Here are a few tips for maintaining a lush Queensland Blue Couch lawn:

Watering Needs

While Queensland Blue Couch is known for its drought tolerance, it still requires regular watering to stay lush and vibrant. 

During the warmer months, it’s important to water deeply and consistently. 

Watering once or twice a week is usually sufficient, but you may need to water more frequently during particularly hot spells, especially in areas like Brisbane or Darwin.

Make sure the water penetrates the soil deeply to encourage deep root growth. 

Shallow watering can lead to shallow roots, which can make the grass more vulnerable to drought stress.

Mowing Queensland Blue Couch

Regular mowing is important to keep your Queensland Blue Couch looking neat. During the growing season (spring through autumn), aim to mow the lawn every 10-14 days. 

Keep the mower height set at 3-4cm, as cutting too short can stress the grass and lead to patches.

In the cooler months, you may not need to mow as frequently. This type of grass grows best when it’s actively growing, so you’ll likely do less mowing in winter when growth slows down.

Fertilisation

To keep Queensland Blue Couch in its best shape, you’ll need to fertilise it regularly, especially during the growing season. 

Use a high-quality, slow-release fertiliser that’s specifically formulated for warm-season grasses. 

Apply fertiliser in early spring and again in early autumn to encourage strong growth and ensure your grass stays healthy and green.

Weed and Pest Control

Queensland Blue Couch naturally suppresses weeds due to its dense growth habit, but it’s still susceptible to certain pests like grubs or aphids. 

Keep an eye out for pests and treat your lawn with safe, natural products if needed.

Conclusion
