Yes, you can scatter grass seed on your lawn. Make sure to check the seed rate, and don’t be afraid to use a grass seed spreader to make this job easier. For best results, we recommend treading or rolling the area you’ve sown the seed to ensure it’s as close to the soil as possible. We recommend reading our guide on how to prepare your ground for grass seed for all the steps.
There is no single best month to sow grass seed. In fact, you have plenty of options, with March to May or September to October being the recommended months. That being said, you can technically sow grass seed for lawns any time of year, but if sowing in the heart of winter, use winter grass seed. If you do get a warm spell, the winter repair mix can be used along with a germination blanket. Sports grounds also use this type of mix for pitch repairs in winter.
The best grass seed for lawns depends on the environmental conditions and how the lawn will be used. We’ve outlined our recommended seed mixes for various purposes above.
