Generally speaking, sowing season in the UK is from April – October. This is when temperatures are most likely to reach the 8-10 degrees and above that is required for germination.
However, some parts of the UK may warm up earlier than this and
sometimes seed is sown in March. Likewise, these temperatures may remain in
some areas all the way into November.
Before deciding to sow, it is vital that you check the temperatures and weather forecast where you are. As said, grass seed needs temperatures of 8-10 degrees and above consistently for seed to germinate. This means not only daytime temperatures, but also temperatures at night. Most weather forecasts now provide a daytime and nighttime temperature, so if you recognise a pattern wherein temperatures are dropping below 8 degrees during the day or at night – it is best to delay your sowing to spring.
The threat of frosts is also something to look out for in your local
forecast – if temperatures are frequently dropping considerably low, you can be
sure that a frost will soon occur. This means the ground will also freeze,
causing soil to become compacted – which is not an ideal foundation for growth for
Temperatures are 8-10 degrees and above in my area, no frosts – can I
If you do plan to sow, it is best to sow a mix at this time with a higher perennial ryegrass content, such as our SUPERSTAR: Back Lawn / FAMILY: Kids and Pets mix. Perennial ryegrass requires slightly lower temperatures than other grass species to germinate, and as long as the right instructions are followed and stuck to – your grass should germinate as expected. Mixes with higher fescue content should be avoided. Fescues require much warmer temperatures of 15 degrees + and it is unlikely that any parts of the UK will be reaching these temperatures in November, consistently, day and night.
Temperatures are below 8-10 degrees and there seems to be some frost
forecast, what do I do now?
Put your feet up and wait! Your lawn will be approaching dormancy soon so grass growth will slow down anyway. If you have purchased our seed in hopes of autumn / winter sowing and not got round to it yet, our seed will keep for up to 1 year if stored in a cool, dry place out of direct sunlight. You may have to wait a little while longer, but your best lawn yet is just around the corner!
Is there anything else I can do to my lawn?
If it's too cold to sow where you are you can always feed your existing lawn to keep it healthy going into the colder months. A SLOW RELEASE: Autumn / Winter will keep your lawn protected from winter disease and frosts for four months, or if you think your lawn needs protection quicker - you can use our fast acting QUICK RELEASE: Autumn / Winter fertiliser.
