Why spring may be the best time to repair your lawn

Autumn is the traditional time for lawn repairs, but we suggest that spring may be best to get to grips with your grass.

After the wet winter, your lawn may be looking a bit worse for wear. A busy summer of use, followed by months of rain, means the grass may be looking sparse, muddy patches have developed and lumps and bumps could make mowing tricky when summer finally arrives.

Many gardening experts argue that autumn is the ideal time to carry out lawn repairs, but if you didn’t tick that job off your garden to do list, then it may not be too late – we argue that spring may actually be the best time to get to grips with your grass.

When is the best time to repair lawn with seed?

Gardeners’ World suggests September – we’re not so sure

Suggesting jobs in the garden for September on an episode of Gardeners World, presenter Adam Frost showed viewers how he reseeds patches that have developed in his lawn over the summer. 

“If your lawn has developed the odd bare patch here and there, September is a good time to repair it, while the soil is still warm,” he explains.

“Simply remove the dead turf [Frost breaks this up with a hand fork], along with any stones and weeds, and work in some fresh soil or compost. Sprinkle the grass seed over the top, taking care not to spread it too thickly, and then water it in.” 

While we agree that September soil does incubate the summer’s heat, repairing lawn with seed in autumn can still be a little risky due to the cooling temperatures.

That’s why we think there’s another season that’s a better time to repair lawn with seed.

Try repairing your lawn in spring instead

Spring brings a better chance of germination

The wet autumn may have dashed your hopes of patching up a summer-scorched lawn, but by doing it now you could get a better chance of success.

Wet and cold weather in autumn can stop seeds from germinating. That’s why spring is increasingly touted as one of the best times to repair your lawn with seed, as the weather is headed on a more predictable and warmer trajectory.   

“If we are lucky and have a warm autumn, then it is possible to use this window of opportunity to reseed areas of the lawn,” explains gardening expert Simon Akeroyd (who’s penned two books on perfecting your lawn). 

“However, if it turns wet or cold then there is a chance some of the grass seeds won’t germinate. Instead, I prefer to patch over the bare areas of my lawn with turf, or wait until it has warmed up in mid-spring for repairing lawns with seed, as you should have a longer period for it to grow.”

Spring for seed is best

So if your lawn does need some extra attention, then we’re approaching prime time for over seeding.

The ideal temperature for grass seed germination is between 10 and 16 degrees Celsius, which tends to be in March, April and May. It pays to be cautious to avoid a late cold spell and, of course, don’t do it during spells of dry weather.

We have more tips on planting grass seed successfully – with an easy trick from Alan Titchmarsh on repairing damaged edges of your lawn too.
