Garden expert shares £1 coin hack to make ideal environment for grass seeds
Despite the warmer, sunnier days arriving in the UK recently, some areas have been experiencing chilly evenings.
With temperatures dropping to as low as 2C in some areas overnight this week, lawn experts are reminding gardeners who have overseeded their grass that warmth is needed for the seed to germinate.
Gardeners urged not to “panic” as lower temperatures could slow grass seed growth
Ben Agnew, grass expert at Lawnsmith, said: “The weather has been quite deceiving. While we’ve basked in the daytime sunshine this month, the evenings have been significantly colder. Some areas of the UK have even seen frost returning.
“Grass seed needs a minimum temperature of 10C to be able to grow with the optimal temperature being more like 12 – 15C. And the chillier nights mean gardeners will see a much slower response from their grass seed.
“This is nothing to panic about, patience is key when it comes to growing grass from seed. And these lower temperatures just mean the germination process will be slower.”
Despite not seeing results yet, Lawnsmith’s expert insists gardeners aren’t necessarily doing something wrong.
Garden expert shares £1 coin hack to check soil depth for grass seeds
Ben explained: “Anyone starting a new lawn or filling in patches might be feeling frustrated with the lack of progress in their lawns. Especially if they’ve spent time and energy taking care of seedlings.
“And thankfully, there is nothing extra that they need to do except keep going with their usual lawn treatment. Keep the seedbed moist, but not pooling water.
“Make sure seeds are at the correct depth to stay protected from the elements and maintain good seed-to-soil contact.
“I recommend sowing your seeds at a depth of approximately three £1 coins stacked on top of each other. This will provide a comforting environment for the seedlings to germinate and grow.
“The worst thing you can do is panic and throw more grass seed down, as this could cause a situation where you lay too much seed and there is competition, leading to poor growth.”

Different seeds have different germination speeds so growers should pay attention to the information provided by the seed manufacturer.
“It can depend on the type of seed used, but typically germination can take five to 15 days,” Ben said.
He added: “Grass seeds like ryegrass or fescue often germinate quickly compared to other varieties like Bermuda that can take longer and require higher soil temperatures.”
