As the sun heats up and the threat of your lawn yellowing increases, you may be looking for another method to keep your grass green and lush. The solution is unexpected. Seaweed is a fantastic natural product with many health benefits, and it can also help you achieve a lush and healthy lawn. It might sound surprising, but now is the ideal time to discover the numerous benefits of using seaweed on lawns.
When you use seaweed in the garden, it offers a remarkable range of advantages for plants. Specifically for lawns, seaweed provides multiple rewards. Not only will they appear greener and more lush, but they will also be stronger against disease, drought, and cold weather. Two experts explained how easily incorporating seaweed into any lawn care regime can be done.
Seaweed contains vital nutrients needed to help cultivate a thick and green lawn. In addition to being nutrient-rich, seaweed also conditions the soil.
It aids in improving the soil structure, which enhances water and nutrient retention and results in the lawn developing a robust root system. Lawn expert Ben Agnew at Lawnsmith told Homes and Gardens that seaweed “provides a biological boost” to grass and should be an excellent supplemental product as part of any lawn care regime, particularly as it can make other lawn feeds work more efficiently.
He said: “Seaweed provides nutrients to improve a lawn’s ability to fight disease, while becoming stronger and greener,’ says Ben. ‘It’s an eco-friendly ingredient which enriches soil with organic matter, supporting root growth and improving the absorption of essential nutrients.”
A stronger lawn fed with seaweed is more resilient against stresses, such as drought and extreme heat or cold, and resistant to turf diseases and pests.
Seaweed is also an eco-friendly way to fertilise lawns and is safe for use around children and pets. Ben Agnew claims that, while seaweed offers many benefits, “knowing how to use it is key” for the best results.
Seaweed does require multiple applications, and the results will improve with repeated use.
Seaweed can be applied to lawns during the growing season, starting when gardeners traditionally fertilise a lawn in spring, once the grass starts growing again.
“Apply first in early spring, and then I’d suggest waiting four to six weeks for the next application,” says Ben. “Your second dose of seaweed will actually triple the impact as the nutrients build up over time.”
Consistency will yield the best results. ‘ Continue applying seaweed every four to six weeks until early autumn. Seaweed can also offer specific benefits when overseeding a lawn in spring. When you overseed a lawn, bare patches in the grass can be quickly dealt with.
Angharad James, product manager at Maxicrop, claims it is “great to use seaweed after overseeding.” She added that “the nutrient-rich seaweed formula not only promotes faster germination but also strengthens young grass against stress and disease for a more hardy lawn.Keep the area moist until the new grass establishes, and soon, those bare spots will be a thing of the past. “
