One of the greatest times to revitalize your grass is in April, when the last vestiges of winter begin to go and the days grow longer. Spring is the best season to tackle any lawn care issue, whether it's bare spots, thinning grass, or a complete overhaul. If you want lush, verdant grass that grows quickly, though, you need to be careful when selecting a seed and even more careful while planting it.
Why April Is a Great Time to Plant Grass Seed
April offers ideal conditions for grass seed germination in many parts of North America. The soil is beginning to warm up, there's typically ample rainfall, and cooler temperatures help prevent stress on new seedlings. These conditions are especially favourable for cool-season grasses, which thrive in spring and fall.
Best Grass Seed for April Planting
For residents of Brampton, Caledon, and Mississauga in Ontario, selecting the appropriate grass seed is essential for establishing a lush, resilient lawn. The region's climate favors cool-season grasses, which thrive in the cooler temperatures of spring and fall. Kentucky Bluegrass is a popular choice in Southern Ontario thanks to its rich green hue, fine texture, and ability to spread via rhizomes, creating a dense and self-repairing turf. It performs best in full sun and offers excellent cold tolerance.
Perennial Ryegrass is another excellent option due to its quick germination—often within 5 to 10 days—which makes it ideal for overseeding or quickly establishing new areas. It tolerates moderate foot traffic and adapts to a variety of soil types, although it prefers full sun to partial shade. Fine Fescue is particularly well-suited for shaded spots and is known for its drought resistance. It's often blended with other grasses to create a versatile and hardy lawn.
When selecting the best grass seed to plant in April, it’s important to consider your region and climate. Cool-season grasses are best suited for northern climates. Perennial ryegrass is one of the fastest germinating options, sprouting in as little as 5 to 10 days. It's excellent for overseeding and repairing patches and prefers full sun. Kentucky bluegrass takes longer to germinate—anywhere from 14 to 30 days—but it spreads through underground rhizomes, forming a dense, self-repairing lawn. Fine fescue is another cool-season option, ideal for shaded areas and known for its drought resistance. Many seed blends combine these three types for greater versatility.
How to Plant Grass Seed in April
Getting your grass seed to grow fast starts with preparation. Begin by testing your soil’s pH using a simple soil test kit; the ideal pH range for most grasses is between 6.0 and 7.5. Loosen compacted soil with a rake or aerator to allow air and nutrients to circulate more freely, and add compost or topsoil if the soil lacks organic matter.
Next, choose a high-quality, weed-free seed that matches your local conditions, including sunlight, soil type, and climate. Spread the seed evenly using a broadcast spreader for large areas or by hand for small patches. Aim for five to ten seeds per square inch to ensure good coverage without overcrowding.
After seeding, lightly rake the surface to mix the seed into the top quarter inch of soil. Water the area immediately and keep the top inch of soil consistently moist for two to three weeks. Applying a starter fertilizer that is high in phosphorus will support strong root development. Avoid high-nitrogen fertilizers in the early stages, as they can encourage top growth at the expense of root health.
Protect the seeded area by limiting foot traffic while the seeds germinate. Begin mowing only when the grass reaches three to four inches in height, and trim it to about two and a half to three inches.
Tips for Growing Thick, Green Grass Fast
Water your newly seeded lawn daily for the first two to three weeks unless there is sufficient rainfall. If you notice bare patches after two weeks, it's safe to overseed those spots. Refrain from using weed killer until after the third mowing, as young seedlings are highly sensitive. A light layer of mulch—such as straw or peat moss—can help retain moisture and protect seeds from being washed away.
Common Mistakes to Avoid
Avoid planting grass seed too early or too late—soil temperatures should be at least 50°F for optimal germination. Using poor-quality seed can introduce weeds or fail to establish a healthy lawn, so invest in premium blends. Overwatering can drown seeds or lead to mold, while mowing too soon or cutting grass too short can weaken young roots and slow growth.
