RPR Perennial Ryegrass Seed
This unique, fast germinating, cool climate Regenerating Perennial Ryegrass (RPR™) outperforms all other Ryegrass. The deep green color and a professional-like turf quality offer remarkable results.
It not only offers unparalleled quality under hard use and traffic, but it thrives in tough conditions. RPR™ regenerates through its creeping growth habit and was designed to develop its own pseudo-stolons (creeping stems) which gives it a regenerative quality that will amaze you.
While it can certainly be used as a standalone variety, the benefits of Perennial Ryegrass really come to the fore when used as a companion grass to other varieties. By combining more than one grass seed in a mix when planting, your lawn can adapt to harsher and more varied conditions. Whether it be surviving heavy shade or direct sun, dry spells or heavy rain, combining two or more seeds with different strengths will counteract out the weaknesses of the varieties.
Active families, larger family pets, and backyard play areas all take their toll on traditional lawns. RPR provides the traffic tolerance, resiliency, and density needed for these demanding situations. If you are looking for a hardy, drought and frost tolerant Perennial Ryegrass that has a turf quality and can still grow under heavy use, then Regenerating Perennial Ryegrass (RPR™ ) is what you are looking for.

RPR™ has a beautiful deep green color and easily withstands high use and abuse. A low maintenance lawn that is extremely disease and insect resistant, it thrives in harsh conditions due to its ability to regenerate using pseudo-stolons.
The combination of fast establishment and regenerative growth potential provides significantly improved weed control over other Ryegrasses.
Optimal pH: 5.0-7.0
Sowing Tips: For best results, sow in a soft, loamy soil that has good water retention. 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.
Optimal Planting Time: If there is sufficient soil moisture, RPR™ will grow at most times of the year in the temperate regions in southern Australia. Perennial Ryegrass traditionally performs best in areas with cooler temperatures and milder summers.
Germination: Under ideal conditions, germination may begin within 7-10 days (climate and season dependent).
Water: Keep moist until the roots are well established. When compared with other perennial ryegrasses, RPR™ exhibits superior drought tolerance. The key to drought tolerance is a well established root system prior to the onset of summer heat. Perennial Ryegrass has a higher water requirement in weather in excess of 28 degrees or when planted in full sun.
Fertilising: Perennial Ryegrass also requires regular fertilisation. Ideally a bi-monthly spread of a high quality fertiliser such as McKays Slow Release Fertiliser, should be applied for optimal performance during the growing season.
First Mowing: It is a fast grower, and will need to be regularly mowed over the fast growing period of spring/early summer. Aim for the blade length to be within the 6 to 12cm range. However, RPR™ can be cut to shorter heights due to the increased density of this variety and ability to regenerate and recover from wear.
Mowing Frequency: 1-2 times/week during active growth.
Disadvantages of RPR™:
- Perennial Ryegrass is at its best in the cooler months and peaks in growth at these times. It can start to struggle during warmer months, and does get particularly thirsty through spring and summer. A heavy watering schedule over these months is advised to keep your lawn looking healthy.
- It can struggle in direct sun during summer months

After months of research I decided a ryegrass lawn would tick all the boxes for my Canberra lawn.
Its frost, wear and shade tolerance were perfect along with the pseudo-stolons of the RPR to help fill in any areas sounded too good to be true. What I was not prepared for was the unbelievable dark green colouring of this lawn.. it looks amazing.
I laid the seed in early August , which in hindsight may have been too early as along with some nice high-teens temps we were still getting regular frosts. I think this caused the first shoots not to come up until about 18 days later as the backyard was seeded in october and had germination within 7-9 days

Great service and advice. Thank you
We couldn’t wait until some warmer weather. Needed grass pronto, and it did take 2 weeks to germinate, but once it did, wow. This pic is 4 weeks after sowing in heavy clay mud. Pretty good for no prep whatsoever! We sowed a new lawn area next to an old (hammered by tradies) kikuyu area, you can see the old sparse area in the pic.
After 2 weeks still has not arrived.
