If your lawn looks patchy, spongy, or moss-covered, a simple change in your gardening routine could revitalize it. Moss is a frequent nuisance in UK gardens, often flourishing in spots where grass struggles to thrive.
Rather than being the root problem, moss typically signals underlying lawn conditions that favor its growth over healthy grass. Gardening expert Monty Don highlights a key maintenance task that can effectively eliminate moss and help your grass grow thicker than ever.
According to Monty, “The best grass thrives in very well-drained soil. Moss is always a sign of poor drainage, often worsened by shade.” Even well-prepared soil can become compacted over time due to matted roots, rain, and normal family use.

The solution is simple: at least once a year, use a garden fork to aerate your lawn. Insert the fork into the soil and wiggle it about every six inches to relieve compaction.
Waterlogged, compacted soil traps moisture and stifles grass roots, fostering moss growth and uneven turf conditions. Aerating the soil opens pathways for air, water, and nutrients to reach roots deeply, stimulating healthy grass development.
After aeration, Monty recommends enriching the lawn with a homemade mix: equal parts sieved topsoil, sharp sand, and sieved leaf mould or compost. If these materials aren’t available, sharp or silver sand alone will suffice. Spread this mixture over the aerated areas, brushing it into the holes with a stiff broom. This improves drainage and feeds your lawn naturally.
Additionally, mulching helps enrich soil while organically preventing weeds and moss from taking hold.
Lastly, give your lawn a thorough wire rake to remove thatch and moss debris built up on the surface. Monty explains, “Scratching the lawn with a wire rake removes overwintering thatch and moss, allowing light and water to penetrate the soil and grass roots.” While this may leave the lawn looking bare temporarily, the grass will return thicker and healthier.
Tackling these simple steps during springtime can banish moss and promote a lush, verdant lawn throughout the season.
If moss persists despite these efforts, experts suggest applying Iron Sulphate as a powerful treatment. When used correctly, it darkens moss within days, making removal easier and restoring your lawn’s vitality.
