A clean cut is essential for healthy grass. Dull blades tear grass instead of slicing it, leaving ragged tips that are prone to disease and discoloration. Sharpen your mower blade every 25–30 hours of mowing or at least once per season.
Scalping the lawn can stress the grass and encourage weed growth. During spring and autumn, keep your cut around 4–5cm. In summer, raise the height to 6–7cm to provide shade to the roots and reduce water loss.
In cooler months, lower the cut to stimulate growth. In hot weather, raise it to conserve moisture. Avoid mowing when the grass is wet or during drought stress.
Compacted soil restricts root growth and water penetration. Aerate in spring or autumn using a fork or hollow-tine aerator. This helps oxygen, nutrients, and water reach the roots for a healthier, deeper lawn.
Low spots collect water and cause uneven growth. Apply a topdressing mix of sand, compost, and topsoil to gradually fill dips and smooth the surface without smothering the grass.
In dry conditions, hydrophobic soil repels water. Wetting agents help water penetrate the soil surface, ensuring moisture reaches the roots. Ideal for dry, patchy areas in summer.
Iron sulfate (FeSO₄) boosts your lawn's green colour, hardens turf, and controls moss. Apply in cool, moist conditions — typically spring or autumn — using a sprayer or watering can. Avoid overlap to prevent dark patches.
Feed with a balanced fertiliser suitable for the season (high nitrogen in spring/summer, high potassium/phosphorus in autumn). Scarify to remove dead grass and thatch, and reseed sparse patches immediately after for best coverage.
One of the most effective and environmentally-friendly weed control methods is manual removal. Use a weeding tool to dig deep and extract the full root, especially with dandelions and other broadleaf weeds. Best done after rain when the soil is soft.
Spot treat persistent or widespread lawn weeds with selective weedkillers like Weedol for Lawns. These target weeds without harming your grass. Apply on dry, calm days and avoid watering or mowing for 24 hours afterwards for maximum absorption.
Liquid seaweed is a natural tonic that supports root growth, improves resistance to drought and disease, and helps your lawn recover after stress. Apply every 3–4 weeks during the growing season, especially after mowing or feeding.
Before overseeding, apply a low-nitrogen, high-phosphorus fertiliser to encourage strong root development in new seedlings. Water in lightly and allow a few days before applying seed to give it the best possible start.
