Queensland Blue Couch is a very popular choice for home-owners in the warmer parts of Australia. It is known for its low growing lush coverage, which provides a soft, weed resistant lawn.

Queensland Blue Couch is a warm season grass suited only to the warmer regions of the country.  It is a very soft, deep blue-green, fine textured grass that has good drought tolerance once its roots have grown deeply. It also does not thatch up like many other warm climate grasses.

It has a similar appearance to a genuine Couch grass, but with a wider leaf blade which tapers into a pointy tip. It has an attractive blue green colour which can turn slightly purple in the Queensland Winter.

In this blend, the Annual Ryegrass provides a safety bed which protects and nurtures the growth of the Queensland Blue. The Annual Ryegrass will eventually die off after 12 months (usually due to warmer weather) and will not return, allowing the Queensland Blue’s runners to take over and fill out the other areas.

For best results, plant in a climate that ranges between 18-25 degrees Celsius, and fertilize a couple times a year with McKay’s Slow Release Fertiliser.

If you are living in parts of Australia where the temperature regularly exceeds 25 degrees, we recommend going with the Pure Queensland Blue Couch Seed as the Annual Rye will not survive long in temperatures over 30 degrees.

Growth Rate



Often referred to as Queensland Blue Couch this grass is neither from Queensland, nor is it a true Couch. It was made popular in Queensland due to it’s optimum performance and suitability to the warm climate.

As this grass is a different species to a traditional Couch grass this needs to be considered when choosing herbicides or pesticides for use on the lawn.


  • Grows best in full sun, requiring more than 6 hours per day
  • Beautiful blue/green colour
  • Premium appearance and soft to touch
  • Recovers well from damage
  • Recovers well from heat stress with light watering
  • Has good salt tolerance
  • Can be mowed very low for bowls or croquet

Optimal pH: Queensland Blue Couch grows well on a wide range of neutral to acid soils; it is tolerant of very acid soils- pH 5.5 and lower.

Sowing Tips: Sow into soft top soil or sandy loam. Broadcast the seed at, or very near, the soil surface and incorporate lightly with raking. To ensure best coverage and avoid seed wastage we recommend using an appropriate seed spreader for the size of your area. Soil must remain damp throughout the germination period of both seeds and must be maintained for at least 1-2 weeks after sowing, through irrigation or natural rainfall.

Optimal Planting Time: Late September to late February.

Germination Expectations: 7-10 days (Annual Rye), 14-21 days (Queensland Blue), condition and climate dependent. Queensland Blue Couch is one of the quicker germinating Couch varieties.

Water: The Queensland Blue Couch Blend requires more watering than the pure Queensland Blue Couch Seed due to the large component of Annual Ryegrass in this blend. The Annual Ryegrass will die off after approximately 12 months and the watering requirements of this lawn will then be the same for the pure Queensland Blue Couch. Queensland Blue Couch is less drought hardy than other Green Couch varieties, but recovers quickly once drought stress is removed. It is tolerant of temporary, though not permanent, waterlogging, but has a low tolerance of salinity.

Fertilising: A low maintenance lawn, Queensland Blue Couch tends to thrive in poor quality soil and copes well with lower levels of fertiliser and insecticide/fungicide than other Couch varieties. For optimal performance and color maintenance, fertilising several times annually is recommended.

First Mowing: Approximately 4 weeks after germination.

Mowing Frequency: In Summer mow Weekly, in Winter mow every 2nd or 3rd week.

Mows beautifully with a cylinder mower or rotary. It can be mowed very low for bowls or croquet (35mm). Once mowed, it never leaves an unsightly appearance of cut and exposed stolons (runners) like other lawns may do. It is less aggressive than real couches, and doesn’t thatch up nearly as quickly as Couch grass. It produces minimal seed heads compared to standard couch varieties meaning this is an easier to mow lawn.

Mowing Tips:

  • Only remove 1/3 of the leaf area at any one time.
  • The lower you mow it, the more often you need to mow
  • In shady areas increase the mowing height of the grass
  • Mowing is the best form of weed control

Disadvantages of Queensland Blue Couch Blend:

  • Queensland Blue Couch is not as traffic tolerant as other couch varieties but it will recover quickly if damaged.
  • Queensland Blue Couch is among the least shade tolerant warm-season turfgrass species.
  • Queensland Blue Couch Blend requires more water than the pure Queensland Blue Couch Seed.
  • Queensland Blue Couch Blend takes longer to establish a pure Queensland Blue Couch lawn than using the pure Queensland Blue Couch.

    FANTASTIC! WOULDN'T CONSIDER ANYTHING ELSE. After many failed attempts to grow seed from a major retail outlet, I had almost given up on grass. I found this though and it was perfect for Brisbane - no issues with thorough germination, continued growth and now i have grass instead of dirt.

    GREAT GRASS. THE PERFECT COLOUR GREEN. Awesome seed stock. I sowed as directed and found new grass shoots popping up everywhere. I did both, new grass sow (on bare soil) and an over sow on existing thin grass, and now have a nice carpet happening across the back yard. Thank you.
