When to sow grass seed:

Not sure when to sow grass in the UK? That's OK because we're here to help. Whether you're a beginner or an experienced gardener, it can be tricky to know when to time it right, as grass grows best when it has plenty of water teamed with warm weather. That's why we'd recommend sowing grass seed in late summer to the middle of autumn.

Will grass seed germinate on top of soil?

If it's your first time using grass seed, it's handy to know whether or not grass seed will work on top of the soil. As grass seed is usually small, a layer of topsoil will reduce its chances of growing.

We understand that this might be a quick solution to prevent birds from eating the seeds. Instead, use a decoy bird feeder, cover the ground with straw or even plant extra seeds.

Do grass seeds expire?

The quick answer to this is yes, grass seeds do expire. You'll usually find a use-by date on the packaging. It's good to know that the older it gets, the less chance the seeds will germinate, especially if your pack isn't stored correctly.

Are grass seeds safe for dogs?

According to All Creatures Healthcare, "The reason that grass seeds can be dangerous for dogs (or even cats) is that they can easily penetrate their outer skin in multiple areas. If left untreated, this can be incredibly painful – in worst-case scenarios, the internal damage it may cause can even be fatal."
