Kentucky Bluegrass seed

out of 5
(4 customer reviews)
  1. Lawn

McKay’s Kentucky Bluegrass is an extremely hardy, good-looking lawn with excellent repair capabilities. It is a cool climate grass, best suited to areas with mild to warm summers and colder winters, like Victoria and Tasmania.

McKay’s Kentucky Bluegrass is a cool season bunch type grass, which also has a unique trait of growing underground runners called rhizomes. While not anywhere near as vigorous as the rhizomes of runner grasses such as Couch, these runners allow Bluegrass to spread itself and thicken the density of the sod providing moderate repair capabilities. While Kentucky Blue does spread, it is not as aggressive as Couch or Kikuyu, making this grass a good fit for any backyard with low garden beds.

Kentucky Bluegrass is very well suited to companion planting with other grass types, particularly Fescues and Ryegrass. This lawn has a medium sized blade and will produce a thick sod which is very soft under foot.

It is an excellent grass for the frost prone areas of Australia, including Victoria and Tasmania as it maintains its color and does not go dormant during winter.

Seeding rates:

Growth Rate



Kentucky Bluegrass grows best during cool, moist weather on well-drained, fertile soils with a pH between 6 and 7.

Sowing Tips: 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. Adequate water supplies need to be maintained until the grass is fully established.

Optimal Planting Time: The optimum temperature for Kentucky Bluegrass is in the range of 15ºC to 28ºC.

Germination:  Approximately 14 days (climate dependent).  Due to the slower growth of Kentucky Bluegrass full establishment can take 1-2 months. However, once established it spreads quickly via its extensive rhizome production.

Kentucky Bluegrass grows by roots from single plants and at the same time sends out stems to form their own roots, making the base denser as it grows.

Water: Kentucky Bluegrass loves water and will need a good, reliable water supply in order to ensure optimal performance. It has higher water requirements than many other grasses. Watering should be deep and less often to encourage the roots to deepen in search of moisture. This will produce a more drought tolerant and disease resistant turf.

Despite this, Kentucky Bluegrass can be an extremely drought tolerant turf. The grass will begin to brown, die off and look sickly without adequate water but can stay alive in it’s depleted state very well (once fully established). If drought is affecting your Kentucky Bluegrass lawn then watering when possible is recommended and the lawn may still come back to life once water conditions improve.

Fertilising: Careful attention will need to be paid to fertilise the new lawn frequently during it’s first year, 3-4 times is recommended in the growing season.  Fertilisers with a higher Nitrogen content are recommended.  Yellowing areas of grass may indicate that the soil is highly alkaline, fertilisers with additional Iron may assist in this instance.

First Mowing: Lawn mowing heights will need to be kept much higher than most other grasses for residential use. Mowing height for Kentucky Bluegrass is 18 – 25 mm on lawns/sports fields.

Mowing Frequency: During it’s peak cool season environment, lawn mowing will need be carried out around once a week to ensure the lawn doesn’t suffer from having too much green leaf removed in a single mowing.

Disadvantages of Kentucky Bluegrass: 

  • At temperatures greater than 30ºC and in freezing temperatures it will go into dormancy but will recover when the preferred temperature returns.
  • Any areas of turf which are becoming worn out or sparse should be re-seeded whenever necessary

    There are plenty of auto rental organizations in England. As for me, Hertz is the most valuable of them all. All of their employees are careful as well as helpful. I hired an auto for 7 days.There was really great office staff again. I'm content to work with them! Five stars are suggested by me!
