As May brings a surge of warmth as well as blooms and colour to gardens across the UK, gardeners are being urged to feed their lawns, and seaweed will only make it greener and stronger. Gardening experts say May is the perfect time to feed your lawn for it to recover after winter, and with soil temperatures having risen enough to stimulate grass root growth. While seaweed may seem more at home on a beach than in a garden, seaweed is rich in essential nutrients and organic matter.
Ben Agnew of Lawnsmith told Homes & Gardens: “Seaweed provides nutrients to improve a lawn’s ability to fight disease, while becoming stronger and greener. It’s an eco-friendly ingredient which enriches soil with organic matter, supporting root growth and improving the absorption of essential nutrients.”
The expert recommends applying seaweed first in the early spring, and then doing a second application four to six weeks later.
Rich in nitrogen, potassium, phosphate, and magnesium, seaweed contains many nutrients that are beneficial to plants.
The Royal Horticultural Society (RHS) says that it has been used as a ‘soil improver’ for hundreds of years and can be bought in dried and liquidised forms from garden centres.
Seaweed can also be used as an additive in both organic and non-organic fertilisers.
Its rich blend of minerals, growth hormones, and trace elements makes it a powerful, eco-friendly supplement that enhances soil structure, boosts plant resilience, and improves nutrient uptake.
According to the RHS, seaweed is a sustainable, renewable source, offering essential nutrients, particularly potassium, magnesium, but also a wide range of trace elements like iron, zinc, copper, manganese, and boron.
Seaweed can help improve both soil structure and nutrient availability, especially in nutrient-poor or depleted soils.
This seaborn plant can help enhance a plant’s resistance to stress, disease, and adverse weather conditions.
