This is the question we are often asked, and people are usually surprised to hear that autumn is one of the best times of year to sow grass seed.
You can sow grass seed when temperatures are 8-10 degrees and above consistently and there is no potential of adverse weather conditions such as frost, snow or flooding forecast for at least two weeks at the time you plan to sow. You may envision this sowing window to be in spring / summer, but contrary to popular belief, sowing grass seed in autumn has lots of added benefits.
When sowing grass seed we need warm soil, moisture and sunlight. In the autumn months September - November the UK still typically hits the temperatures of 8-10 degrees and above which is required for germination. With temperatures pinned down and ideal for sowing, there are even more advantages to sowing grass seed in autumn:
More rain, less watering! With rain more frequently forecast in autumn, you can sow your grass seed and then retire the garden hose / watering can.
Fewer weeds to combat Weed growth naturally slows down in the milder months as the ideal conditions for them to thrive in wind down.
Get ahead By sowing in autumn you'll have a luscious lawn ready for summer meaning you can sit back, relax and enjoy the fruits of your labour!
No birdy business! There is a reduction in the risk of birds snacking on your newly sown seed due to migration and the availability of other food during winter.
If these benefits are enough to convince you to sow grass seed in autumn, here's how you should do it:
Overseeding an existing lawn
Remove any dead grass, weeds or moss by scarifying / raking the area
Rake the area enough so that the soil is loose and the seedbed is level
