As our nights begin to grow darker you may start to think that sowing season has ended. However, where temperatures are still 8-10 degrees and above – autumn presents an excellent opportunity for grass seed sowing.
Sowing grass seed
The best times of year to sow grass seed are in spring and autumn, not only for quick growth but for your own forward planning. Seeding / or overseeding your lawn in spring enables you to enjoy your new green grass for all of the summer, and sowing a new lawn / repairing grass in autumn means when spring rolls around the majority of your work is done!
Most grass seed species will germinate at temperatures of 8-10 degrees and above, so as long as the temperatures forecasted in your area are hitting these consistently for two weeks with no frost or adverse weather conditions forecast (heavy rain etc.) then you should be able to sow with confidence. Some more specialist species, such as Poa Supina require warmer temperatures of 15 degrees and above to germinate, so if you have chosen a mix such as our STEADFAST: Ultra Shade you should consider this.

autumn seeding a success
Once you’ve completed your prep work and the temperatures in your area are sufficient for germination, you’ll want to ensure that all that hard work doesn’t go to waste. A great way to speed up germination and keep a healthy lawn going into the colder months is by fertilising your lawn. If sowing a new lawn from scratch, you should aim to use our QUICK RELEASE: Pre-Seed before sowing, and if overseeding a SLOW RELEASE: Autumn / Winter fertiliser will help to protect all your hard work.
- Whilst your new grass is establishing it is important to keep leaves off it. This extra unnecessary moisture on top of your new grass can cause disease – remove leaves when you see them gathering.
- Autumn is a great time for sowing seed as there is typically more rainfall forecast which requires less watering for you! During the first 6 weeks of establishment, you should aim to keep your new seedlings moist – if there is prolonged rainfall, avoid watering your seedlings.
- As always, your lawn should be ready for its first mow at the 6-week mark and when blades are hitting 5-7cm long. Cut your lawn on the highest setting for its first mow. You can read more on our guide The last grass cut of the season here.
