Annual Ryegrass Seed
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.
- 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

Delivery arrived within the agreed time frame. We oversowed our couch shortly after it arrived and it started to germinate within a couple of weeks. We were retained we had missed our window as the Melbourne winter had hit, but it is going strong.
We have Sir Walter buffalo (in Brisbane) which tends to go dormant over winter and become quite bare and patchy in our shady yard, especially in high traffic areas. We'd also had a digger through installing a new stormwater pipe through the middle of the lawn a couple of months ago, which we patched with turf, but there were still gaps. This rye grass was sown 10 days ago and the lawn is already looking so much greener, with the gaps starting to be filled in. This is with cold morning temps (6-9 degrees) and mostly shaded. Great stuff!
Alas, too hot to sow the seeds. Will sow in early Autumn .
