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).

Sowing Tips: Sow into the 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: McKays Slow Release Fertiliser can be used to prepare the soil for sowing of Annual Ryegrass.
First Mowing: When Annual Ryegrass is approximately 5-7cm 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 5cm above ground level and repeat the mowing when the grass grows about 2.5cm 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 12 months (approximately)
- Needs to be resown annually

Ordered 20kg of Rye Grass for new work on our acerage after serious storm damage.. Several messages from McKays kept me in touch with the delivery progress, which was very quick and to my door. Getting the seed in 4 x 5kg bags made sowing easy. The place is greening up as I hoped. Very happy.
I'm really blown away! Purchased on the 1st of November 2021 I was told I'd have thick lawn by Christmas !! Not wrong at all!
With a mixture of Annual Rye and Kikuyu along with some slow release fertiliser, not only id we have a lush thick lawn for Christmas but very very cost effective front and rear lawn solution! It's now the 3rd of January 2022 and I've just cut back my front and rear lawn, it's magic to walk and run on and it just looks amazing. Seriously couldn't ask for more! Outstanding service and a brilliant product, trust me I'm no green thumb but I've got a very impressive lawn around our new house. Outstanding!
The Annual Ryegrass is now growing. Started coming out exactly 6 days after planting. I can also see it coming up everywhere. Watered constantly and the rain that fell within that period also helped.
Very happy with the results

Fast, quality service
