A prominent broadcaster and horticulturist Alan Titchmarsh, 75, has revealed when Brits should mow their lawns for the first time each year. He urged gardening fans to wait before trimming their grass to early, a common mistake people make. The horticultural expert and author from Ilkley is known for his extensive knowledge of plants and wildlife, writing books such as Love Your Garden and The Nature of Britain.

He said that March 18, the average day when gardeners tend to cut their grass, is too early for one reason.

This is because the lawn remains dormant during the colder seasons, such as autumn and winter, so mowing it prematurely can actually weaken it.

According to the Woodland Trust, grass only grows when the soil temperature reaches above six degrees Celsius. According to the trust, that grass is one of the earliest plants to start growing in spring, and one of the last to stop growing in the winter.

The trust added that less than a third of the height is ideal and that you would soon be able to take more off over the upcoming weeks without damaging it.

To avoid damaging the grass or compacting the soil, the organisation recommends waiting a few days for the ground to dry out, as the weight of the mower can be destructive when too wet.

This comes after the TV gardening expert had said he had issues with the impact avocado-eating millenials have on the environment.

He told The Times: "Most of those sold in the UK are grown where the rainforest has been felled at an alarming rate to accommodate them.

"They are then shipped, often more than 5,000 miles across the ocean, as breakfast for supposedly environmentally friendly consumers.

"There's a lot to be said for Cornflakes, Weetabix and Shreddies."

Last year, the gardening expert also gave an insight into how he opts for one mower over another, as it helps provide his favoured pattern: "I use a rotary mower but with a heavy rear roller as oppposed to four wheels, because the heavy rear roller gives me the stripes that I like. So, it's a rotary instead of a cylinder that is generally used on fine lawns."
