Couch Grass

Couch Grass

Couch grass is now arguably one of the most popular lawns in Australia and well-known by most homeowners for being a highly attractive ornamental variety. Couch breeds like OZTUFF®Couch & Stadium Sports Couch offer homeowners a hard-wearing and tough lawn that is ideal for coastal areas and poolside due to its high salt-tolerance.

Previously Couch grass had a reputation for being a weed but through extensive breeding, this lawn has many key benefits to offer.

Why Choose a Couch Grass?

couch grass in park.Couch is a warm-season grass that is now known for its drought and wear tolerance, softness underfoot, greener colour and water efficiency. With a fine leaf blade that produces dense growth, Couch grass is ideal for a wide variety of uses and copes well with high wear situations such as backyards and sporting fields.

One of Couch grass’ most favoured features is its natural dark green colour and ability to maintain good colour even in poorer quality soils compared to all other turf varieties. The shade tolerance of Couch lawn is about 10%, which is similar to Kikuyu grasses. However, Couch lawn thrives and stays alive for longer than other turf varieties in hot, dry conditions.

Aussie home-owners choose a couch grass lawn for a variety of reasons:

  • Great drought tolerance
  • Wear tolerant for kids and pets
  • A fine leaf that is soft to touch
  • Beautiful dark green colour
  • Salt tolerant for seaside homes

Couch Grass Features

1. Great Drought Tolerance

drought stricken lawn

The robust deep-rooted system of Couch grass gives it an advantage over other varieties during drought and stressful conditions.

Once Couch lawn has dried-off due to lack of water, it is one of the first turf varieties to easily recover.

The variety’s high drought tolerance makes it an ideal choice for areas where water restrictions are commonly imposed.

2. Wear Tolerant

Hard-wearing grasses are ideal for families wanting a place for children and dogs to play or where the lawn is used as a walkway.

The ability of Couch grass to develop a moderate thatch layer provides greater wearability and recovery.

Couch grasses extensive deep root system aids in its wear tolerance making it an ideal option for homeowners with kids and pets.

3. Fine Leaf

Many homeowners prefer a particular leaf that resonates from childhood or where they have seen turf in different areas such as sports fields or gardens.

Different grasses have different leaf widths, folds, tip shapes and colours which offer different soft to touch underfoot and aesthetic appearances.

The Fine leaf classification is the narrowest of all the leaf types. Couch grasses today have a finer leaf blade than most other turf varieties making it soft to touch and dense underfoot.

The finer leaf of Couch lawn also means there is less water evaporation – another reason it is ideal for hot, dry conditions.

4. Dark Green Colour

Couch grass dark green colour has seen it stand out compared to other lawn varieties and maintains its colour for longer.

This dark green colour is also maintained even when Couch grass is planted in poor quality soils.

Couch grass is also able to maintain the dark green colour in soils where nutrition is considered inadequate for other lawn varieties.

5. Salt Tolerance

Couch grasses have the highest salt tolerance compared to most other lawn varieties making it ideal for coastal areas and pool sides.

Salty soils can prevent lawns from absorbing both water and nutrients, however, Couch grass has the ability to cope with low water and nutrients giving it a high salt tolerance.

Lawn Care Advice for Couch Grass

As Couch grass has seed heads that are usually only produced during the establishment period or when under stress, the seed is not viable, meaning it will not reproduce in your neighbour’s yard. The unviable seed head of Couch grass, outside of its establishment period, also results in less mowing and edging.

A lawn care & maintenance routine for your Zoysia lawn should include:

  • Mowing
  • Watering
  • Fertilising
  • Lawn Weed & Pest Control
  • Disease Prevention

lawn maintenance IconMowing Couch Grass

Much of the Couch lawn’s growing energy is directed laterally therefore, the lack of upright growth coupled with its fine leaf structure, significantly reduces mowing frequency.

During summer and spring: Mow Couch grass twice a month at a height of about 18mm-25mm.

During winter and autumn: Mow Couch grass once a month (sometimes less) at a height of 25mm-30mm (5mm – 10mm higher in shaded areas).

lawn watering IconWatering your Couch Lawn

Newly laid Couch grass requires a deep watering at least once a week.

Once the deep-rooted system of your Couch grass has been established, you can water thoroughly only when needed (for example, when slight wilting is visible).

If you want to learn more about watering, make sure to read out guide to watering a new lawn.

Watering an Established Couch lawn

Once your Couch grass is established during summer water every 7 – 10 days (on sandy soils more often) and with much less water in cooler months.

If water restrictions are enforced and your Couch grass browns off slightly, it will green up quickly when you can water again, or if it rains.

Watering your Couch during winter will also improve winter colour.

fertiliser IconFertilising Couch Grass

Fertilising your lawn

During the warmer growing season, you only need to fertilise your Couch grass every 10-12 days.
