Detailed Description
Annual Ryegrass is a versatile Australian option for various applications, known for its rapid growth and adaptability. Ideal for winter oversowing, rapid ground coverage, temporary erosion control, and weed suppression, it provides excellent shade tolerance and traffic resilience.
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 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. Water approximately once per week after establishment, and as needed during hot weather.
Fertilising
McKays Slow Release Fertiliser can be used to prepare the soil for sowing 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.
Mowing Frequency
Depending on the purpose of the Annual Ryegrass, residential lawns where shorter heights are preferred may need mowing twice a week during the active growth phase.
Disadvantages of Annual Ryegrass
- Only lasts for approximately 12 months.
- Needs to be resown annually.
