Can I sow grass seed in November?
The sowing season for growing grass seed in the UK is from April – October. These months are when temperatures are most likely to reach 8-10 degrees and above required for germination. If you are planning to sow grass seed in November, there are some things you must take into account for successful germination.

However, some parts of the UK may warm up earlier than this, and sometimes the seed can be sown in March. Likewise, these temperatures may remain in some areas all the way into November. This guide goes into detail, explaining what is necessary to sow grass seed successfully to begin germination in November.

What temperatures are needed to sow grass seed in November?

You must check the temperatures and weather forecast for the area where you live before deciding to sow. As mentioned, 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 daytime and nighttime temperatures. So, if you recognise a pattern where 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 the soil to become compacted. This climate is not an ideal foundation for the growth of new seedlings. This means you're better off waiting until spring before you sow!

Temperatures are 8-10 degrees and above in my area – can I sow grass seed in November?

If you do plan to sow, it is best to sow a mix at this time with a higher perennial ryegrass content. Using seeds such as our SUPERSTAR: Back Lawn / FAMILY: Kids and Pets mix would be ideal. Packed with perennial ryegrass, these mixes require slightly lower temperatures than other grass species to germinate. As long as the growing 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 have not got around 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 for 4-6 weeks protection or our fast-acting, nutrient-dense Make it Strong liquid fertiliser to feed your lawn for 6-8 weeks!
