So, How Long Does Grass Seed Take to Germinate?
Your grass seed will sprout within 7-10 days with the right conditions when using the right grass seed suited to your garden’s needs. This doesn’t mean it will all grow at once, but rather that the germination process has started, and your lawn is well on its way to becoming lush and green! Keep reading for more detailed advice on how long for grass seed to germinate.
Grass seed germination is like the first chapter in the life of your new grass seeds. It’s when they wake up and start growing, becoming your new lush green garden lawn in the weeks that follow!
How do I tell if my lawn seed is germinating?
The most straightforward and obvious way to determine if your lawn seed is germinating is to look for shoots of grass starting to push up through the soil. If you can see grass appearing on the surface, you know your grass seed is germinating successfully.
As mentioned, germination usually takes around 7-10 days. Still, if you do not see any grass appearing after two weeks, then there may be something limiting the growth of your seedlings, and you will need to look at the growing conditions of your lawn. Luckily for you, we’re here to help - so keep reading our expert advice to ensure your grass seed germinates...
Sowing Your Seed at the Right Time
To ensure the conditions for growing are right, you should look at your local weather forecast for temperatures of 10°C and up for two weeks, and then sow your grass seed correctly in the right areas of your garden. In the UK, each season offers unique advantages for sowing seeds and grass seed germination.
Sowing Grass Seed for Spring Germination
Spring creates the ideal environment for germinating grass seeds. This season brings rising temperatures, more frequent appearances of the sun’s rays, and reliable rain showers; it provides the perfect weather conditions for your new grass seedlings!
Sowing Grass Seed in Summer
Sowing grass seed during the summer requires a bit more effort, but it can provide quick results if done correctly. Higher temperatures demand extra care for the young seedlings, but don’t be tempted to sow when it’s very hot outside or during a heatwave.
The abundance of sunlight during summer encourages rapid growth once the grass sprouts from the ground – your grass seed will germinate and grow well if you avoid planting in very warm temperatures (20°C +) and keep your soil damp. But be aware of approaching heatwaves, as they often mean there will be a hosepipe ban, so remember to water your lawn accordingly during these times!
Autumn Grass Seed Germination
Autumn is the perfect time for planting grass seeds, and many gardeners agree! As summer comes to a close and temperatures gradually return to normal, early autumn emerges as one of the best times to sow grass seed in the UK. The milder climate, soil that’s still warm from summer and light rain showers provide an optimal setting for successfully establishing grass seedlings.

Tips for speeding up grass seed germination
Our tips below offer advice to make your grass seed germinate and get off to the right start!
Sow your seeds in the right conditions for them to grow. Spring and autumn are arguably the best times to plant grass seed since the temperatures are at least 10 °C day and night, and there is often enough rainfall to do most of the watering for you.
Water Your Grass to Keep the Soil Moist
Keep your soil moist, but don’t go crazy. Your seeds need water from the moment you sow them into the soil, but be aware that too much water can be just as bad as not watering them at all! We recommend watering your new lawn every day for the first six weeks to help your grass seed to germinate as best it can. You can hold off watering on days when it rains outside, and after this time, your grass should be getting close to being long enough for its first mow.
Protect Your Seedlings While They Germinate
After all your hard work up to this point, the last thing you want is your grass seeds to be snatched away by birds. So, cover your newly seeded area with netting or hang old CDs around your garden to stop birds from undoing all your hard work!
Time for Your New Lawn’s First Mow
After giving your seedlings at least six weeks to germinate and establish, your lawn will be ready for its first mow. The first mow needs to be done using your mower’s highest setting; then, you can gradually drop to the recommended height for your type of lawn: 20 - 40mm for a family lawn and 10 - 20mm for an ornamental one.
Knowing how long for grass seed to germinate
You’re on your way to having a stunning garden lawn! Knowing how grass seed grows and what affects its germination time sets you up for success. So, get the right seeds, water like a pro, and remember – patience pays off! Soon enough, you’ll have a beautiful, green, and envy-worthy garden lawn.
