Lawn Fertiliser with Moss Killer, 14 kg bag

Multitanks Lawn Fertiliser with Moss Killer 14 kg (Reference: SOGAZMOU350P) is the professional way of dealing with moss and lawn nutrition at the same time. This organo-mineral formulation, certified to the French standard NF U 42-001, combines the effectiveness of iron sulphate against moss with the nutritional benefits of a balanced NPK fertiliser, for a dense, vigorous and lastingly green lawn.

Benefits and use cases

This moss-killing fertiliser meets the needs of private homeowners who care about the beauty of their lawn, as well as those of landscaping professionals and green space managers who require fast, lasting results. It is perfectly suited to lawns weakened by damp, shade or compacted soil, where moss takes hold.

Application is recommended in spring and autumn, the best times for lawn regeneration. Sports grounds, private gardens, urban parks and golf courses benefit particularly from this preventive and curative treatment. The dual action avoids separate treatments, saving both time and maintenance costs.

Technical features and innovation

The scientifically studied composition combines 152 g/kg of monohydrate iron sulphate (15.2%) for the moss-killing action with an NPK 6-4.5-4 fertiliser for nutrition. The organic nitrogen (5% of the 6% of total nitrogen) comes from meat meal and vinasse extracts, ensuring gradual release and biological stimulation of the soil.

Phosphorus (4.5%) encourages rooting and the resilience of the lawn, while potassium (4%) strengthens resistance to water stress and to disease. This balanced formulation suits chalky as well as acid soils, with a pH-regulating action thanks to the iron sulphate.

The specialised granulation limits the formation of dust, making handling easier and reducing the risk of inhalation. The even spread of the granules ensures uniform distribution of the nutrients and of the moss-killing active ingredient.

Application and directions for use

Application is best carried out in dry weather, avoiding periods of frost or high heat. Recommended dose: 35 to 40 g/m², which means a 14 kg bag covers about 350 to 400 m². Spreading can be done by hand on small areas or with a fertiliser spreader on larger ones.

Before treatment, mowing to 3-4 cm helps the product penetrate. After spreading, light watering activates the dissolution of the iron sulphate and speeds up the moss-killing action. The first effects are visible within 7 to 10 days, as the moss turns brown.

Raking out the dead moss should be done 2 to 3 weeks after treatment, followed by overseeding if necessary to thicken the lawn. Regular watering helps the nutrients to be taken up and the grass to reclaim the areas freed from moss.

Tips, combinations and expert advice

For maximum effectiveness, combine this treatment with a soil aeration programme in spring. Using a scarifier before application improves the penetration and the action of the product. Complete your strategy with hard-wearing grass seed to strengthen the bare patches.

Take care with hard surfaces: iron sulphate can stain concrete, paving slabs or clothing. Protect these when applying and rinse immediately in case of accidental contact. Avoid applying to a wet lawn, to prevent the granules sticking.

The frequency of application varies with the condition of the lawn: a curative treatment 1 to 2 times a year for heavily affected lawns, an annual preventive application for routine upkeep. Pair it with a slow-release fertiliser in summer to keep the lawn vigorous.

Store ideally in a cool, dry place, away from the damp that could spoil the granulation. The 14 kg bag suits gardens of 350 to 400 m², or allows several applications on smaller areas.
