Depending on what you're hoping to achieve with your lawn, how you look after it - and the grass feed you use - can have a big effect on how it grows.
If you're aiming for biodiversity, encouraging wildflowers and weeds to grow so that insects can pollinate, it's best to avoid using weed killers and pesticides. There are some lawn feeds that have weed killers built into the formula, so it's important to make sure you're choosing the right product for your lawn.
Wondering how to stop birds eating your grass seed?
Regardless, lawn feeds can give your grass a healthy boost in growth and strength, encouraging stronger roots and thicker, greener grass. The optimal time to apply it is between early spring and autumn - but each formula is designed to be used a certain way, so it's best to check each formula is suited to your needs.
We've rounded up the best grass feeds for your garden with summaries to help you make the right decision.
Best lawn feed for thick, green grass
Plantworks Ltd Empathy Lawn Feed Liquid
Empathy's Supreme Green Lawn Feed is a seaweed-based liquid concentrate that can help feed and condition your lawn. Seaweed is a natural plant and soil stimulant and using such a biological stimulant can be a more organic way to care for grass.
Suitable for all lawns, this one litre bottle is enough for 50 watering cans (or nine litres). The grass feed formula is made using seaweed extract from sustainably harvested kelp. Through the process, a range of vitamins and nutrients are retained to maximise how effectively it can treat lawns. Iron, nitrogen and other nutrients are added to improve grass greening and other benefits.
