Annual Ryegrass Seed

Key Features:

McKay’s Annual Ryegrass as the name suggests is a 1-year proposition that provides excellent quality Autumn, Winter, and early Spring growth. The forage quality drops in late spring with the onset of seed head emergence. The plants have usually died off summer. Annual Ryegrass will not regenerate and requires annual reseeding.

It is often used to overseed warm-season lawn grasses (such as Buffalo, Couch, Zoysia, Kikuyu, Queensland Blue) to provide a green, economical grass cover from Autumn to Spring. It can also be used for weed suppression and temporary erosion control.

Annual Ryegrass is an easy to establish grass, bred to provide quick winter pastures and, with sufficient moisture, seeds will even germinate when broadcast on top of established lawns or pastures. It is typically suited to winter rainfall and areas with hot, dry summers.

Seeding rates: 

  • New Lawns: 30 grams per square meter (3kg/100m2).
  • Overseeding: 20 grams per square meter (2kg/100m2).
  • Note: Annual Ryegrass Seed will only grow for 1 year

Sowing Tips: Sow into soft topsoil or sandy loam. Broadcast the seed at, or very near, the soil surface and incorporate lightly with raking. To ensure the best coverage and avoid seed wastage we recommend using an appropriate seed spreader for the size of your area. The 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: Autumn sowing is recommended.

Germination: 7~10 days with sufficient water, climate-dependent.

Water: Ensure soil remains damp throughout the entire germination period. Approximately once per week after the establishment of grass, and as needed during hot weather.

Fertilizing: McKay’s Slow Release Fertiliser can be used to prepare the soil for sowing of Annual Ryegrass.

First Mowing:  When Annual Ryegrass is approximately 5~7cms tall. This demonstrates that the roots are strong enough to withstand the wheels of the mower and should not be pulled out during mowing.

For residential use, set the mower to cut at approximately 5cms above ground level and repeat the mowing when the grass grows about 2.5cms above the set level.

Mowing Frequency: Depending on the purpose of the Annual Ryegrass. Residential lawns where shorter heights are preferred may need to mow twice a week during the active growth phase.

Disadvantages of Annual Ryegrass:

  • Only lasts for (approximately) ~12 months
  • Needs to be resown annually
