Why This Seed?

Perennial Ryegrass is one of the most popular grass types and is an ideal choice for those wanting a manicured lawn with great stripes, or for over seeding. The main advantage of Perennial Ryegrass is its fast germination, typically 4-7 days, meaning it is the best option to fill in bare spots quickly, or to have high success rates when over seeding. Perennial Ryegrass can be cut short if wanted to give that "golf course" quality look, has great wear tolerance, and is used in many professional sports fields including soccer pitches and tennis courts like Wimbledon. If you are looking for an almost instant improvement to your lawn, Perennial Ryegrass is the choice for you.

Technical Details

Perennial ryegrass (Lolium perenne) is used extensively in cool-season turf systems because it brings rapid germination and fast ground cover, which reduces the time soil is exposed and vulnerable to erosion and weed invasion during establishment or renovation. The Guelph Turfgrass Institute explicitly notes perennial ryegrass’s “very quick germination” (about a week) and its role in mixtures: it is often blended with slower-germinating Kentucky bluegrass to provide immediate coverage while bluegrass establishes. Municipal turf guidance from Guelph reinforces this practical trait difference (ryegrass fast, bluegrass slow) and frames ryegrass as useful for overseeding and blending, while also noting ryegrass is bunch-type (no rhizomes) and not as winter-hardy as Kentucky bluegrass—important context for Canadian long-term persistence.

From a turf research standpoint, ryegrass is also valued because many modern cultivars carry endophytes (symbiotic fungi living within plant tissues) that can improve tolerance to certain insects and stresses. Rutgers turfgrass proceedings describe how endophytes in perennial ryegrass can contribute to biotic and abiotic stress tolerance and can reduce damage from above-ground feeding insects. In practical lawn terms, a cultivar blend like Slider LS, Grandslam GLD, and Torsion LS is typically designed to maximize tiller density, turf uniformity, and wear tolerance while maintaining the ryegrass advantage of quick establishment that Canadian homeowners and pros rely on for renovation, patch repair, and high-use areas.

"I used seed and fertilizer from The Lawn Medic in the Spring. The transformation over about 5 weeks was incredible. The pictures tell the story. The new lawn came in thick and green and it has stayed that way all year. No weeds. Strong growth."

Step-by-step Seeding Guide

A quick version of our seeding guide

ONE

Cut Your Lawn

The first step to seeding is cutting your existing lawn. The goal is to cut it shorter than usual, shocking your grass to top it from growing and making it easier for your new seed to filter through the blades and touch soil.

TWO

Dethatch your lawn

If you are overseeding, dethatching (with a rake or powered) is a suggested step as it helps to remove thatch and debris from your lawn, helping seeds to find soil, but also allowing water to find the seeds more easily.

THREE

Aerate your lawn

Areation is optional when seeding, but if your soil is compacted or you were planning to aerate, this is a great time to do iit.

FOUR

Topdress your lawn

Topdressing is another optional step. If your lawn is bumpy, and you want to level it, now is a great time. However topdressing is not required for seeding. One of the most important aspects of seeding is seed-to-soil-contact. If your seed is able to properly touch soil in your lawn, then topdressing is not required.

FIVE

Seed your lawn

It is finally time to seed your lawn. Pick the right seed for your yard and spread it using a push or hand held spreader. We recommend applying your seed in multiple directions as this helps to ensure an even spread.

SIX

Roll Your Lawn

In order to ensure as much seed-to-soil-contact as possible we recommend rolling your lawn after seeding. This helps to push the seed down into your lawn and onto the soil. Your seed must touch soil in order to properly germinate.

SEVEN

Cover Your Lawn

We highly recommend covering your newly seeded lawn with peat moss (or similar) if possible. Peat moss acts like a sponge, holding moisture on your seeds and cutting down on water requiements. It also helps. to protect your seed from un-off and birds.

EIGHT

Water your lawn

Keeping your newly seeded lawn watered is the most important step. We recommend watering 3-5 times a day for 4-10 minutes. This depends greatly only your sprinkler setup, the amount of sun, temperature and a number of other variables. Do not let your seeds dry out.

NINE

Wait for your lawn

And now you wait. Depending on the soil temperature and the seed you are using germination could happen in less than a week, or up to three weeks. Keep watering properly and be patient.

TEN

Cut your lawn

Once your new lawn is 2-3" in height your can cut it for the first time. We recommend sharpening your blade before cutting, and limiting turns as much as possible. You want to be gentle with your new lawn.

ELEVEN

Fertilizer your Lawn

We recommend waiting until you cut your newly seeded lawn 1-2 times before fertilizing. Using a fertilizer that is high in Phosphorus, like our starter fertilizers, helps to promote root development and create a stronger, healthier lawn.
