Professional Grade Iron Sulphate Lawn Sand

Pro-Kleen’s Lawn Sand is a professional-grade lawn treatment designed to restore tired grass fast. Its powerful formulation, enriched with iron sulphate (ferrous sulphate), helps lawns grow stronger, greener and healthier with visible results in a short time. Trusted by UK lawn care professionals, this fast-acting lawn sand delivers reliable performance for domestic and commercial use alike.

Works Quickly To Improve Lawn Quality

This fast-acting powdered formula works quickly to improve lawn colour and condition. A key active ingredient is iron sulphate, a highly effective source of soluble iron that is rapidly absorbed by grass. Iron sulphate enhances chlorophyll production (the compound responsible for your lawn’s rich green colour), delivering a noticeably deeper green appearance within days of application. As well as boosting colour, iron sulphate helps toughen grass blades, improving their structure and resilience.

Powerful Nutrition For Strong & Vibrant Grass

With a formulation of 5:0:0 +3Fe, this lawn sand contains 5% nitrogen to support strong and steady plant growth while promoting thicker, healthier grass. Nitrogen fuels leafy development and helps lawns recover from wear, stress and seasonal damage. The added 3% iron, supplied from iron sulphate, delivers multiple additional benefits. Iron intensifies natural lawn colour to create a rapid greening effect without encouraging excessive soft growth, while also supporting improved chlorophyll production for more efficient photosynthesis and stronger overall grass health. It contributes to stronger cell structure, helping grass blades grow firmer and more upright, and enhances root vitality by supporting healthy root development and nutrient uptake. Unlike products that rely solely on nitrogen for colour, the inclusion of iron sulphate provides a rich, deep green finish without overstimulating growth, helping to maintain a well-balanced, resilient and manageable lawn.

Feeds, Greens & Strengthens Your Lawn

Pro-Kleen’s Lawn Sand nourishes grass for strong, even growth and improved coverage, while enhancing lawn colour for a deep, healthy green finish. The iron sulphate content works in harmony with nitrogen to strengthen grass from root to tip, improving overall lawn density and durability. Iron also plays a vital role in enzyme function within the plant, supporting internal processes that improve resilience against environmental stresses such as drought and disease. The result is grass that not only looks greener but is physically stronger and better equipped to thrive.

Transform Dull And Weak Lawns

Pro-Kleen’s Lawn Sand is designed to transform tired lawns into lush, healthy green spaces. The fast-acting iron sulphate quickly revitalises pale, yellowing grass, restoring a vibrant appearance while reinforcing plant health below the surface. Encouraging healthy root growth, it creates more resilient turf that withstands foot traffic, dry weather and seasonal stress far more effectively.

The Benefits Of Iron Sulphate In Lawn Care

Iron sulphate has long been trusted in professional lawn care due to its multi-functional performance. Its benefits include: Deep, rich green colour without excessive top growth Improved grass blade strength and upright growth habit Support for essential plant metabolic processes Enhanced overall lawn density and visual appeal
