One surprise ingredient could be the secret to having the perfect law come springtime.

Winter can take its toll on our gardens, particularly the lawns, which can be left patchy and weak. But an unexpected natural ingredient could be the key to reviving grass ahead of the warmer months.

Lawnsmith's Ben Agnew has recommended putting seaweed in your lawn, as it provides a biological boost to your grass.

He explained: "It provides nutrients to improve a lawn's ability to fight disease while becoming stronger and greener.

"While it shouldn’t be used instead of fertiliser, it’s a great supplement for lawns and actually improves how efficiently fertilisers work.

"It’s an eco-friendly ingredient which enriches soil with organic matter, supporting root growth and improving the absorption of essential nutrients."

Ben recommends using seaweed on your lawn by sprinkling dried seaweed granules by hand or with a spreader. For faster absorption, mix granules into water. Then, anywhere from a week to a month later, follow this with some fertiliser. 

Alternatively, you can use a fertiliser that already has seaweed built-in, as this will guarantee your lawn treatment is balanced and ensure there is no risk of oversaturation.

While seaweed is certainly beneficial for the law, Ben highlights the need to be careful of just how much you use, saying: "It can cause a salty buildup in the soil, hindering water absorption and damaging the roots. Too much organic matter from seaweed can cause excessive thatch.

"But when used correctly, it can be fruitful for your lawn. Providing a rich boost of minerals including potassium, magnesium and iron which all help strengthen grass and improve resistance to fungal infections."

It's also important to remain consistent with your lawn treatments, with Ben advising that you should you should do this once in February and then wait another six weeks before repeating.

He explains: "Dry, mild days are best for application, as frost and wet weather can prevent the seaweed being retained."
