A lush, green lawn is the pride of any homeowner or gardener. However, achieving and maintaining such a lawn requires proper nutrition, which is where fertilisers come in. Lawn fertilisers provide essential nutrients that support healthy growth, improve resistance to pests and diseases, and enhance the overall appearance of your grass.
Understanding Lawn Fertilisers
The nutrient composition of lawn fertilisers supply three primary nutrients, commonly referred to as N-P-K, which stands for:
- Nitrogen (N) – promotes leafy, green growth.
- Phosphorus (P) – supports root development and strength.
- Potassium (K) – improves disease resistance and overall lawn resilience.
What is the Difference Between Granular Lawn Fertiliser and Liquid Fertilisers
Granular fertilisers – are small pellets that release nutrients gradually over time such as our KissMyGrass Slow Release Lawn Fertiliser, which noursihes lawns over several weeks.
Liquid lawn fertilisers – are diluted in water and applied using a sprayer or watering can. They provide an instant nutrient boost but require more frequent applications.
Organic vs. Synthetic Fertilisers
Organic fertilisers – are made from natural materials such as compost, manure, bone meal, or seaweed extracts. Our KissMyGrass Seaweed Liquid Lawn Fertiliser contains 100% seaweed extract to help strengthen grass roots and offer disease resistance.
Synthetic fertilisers – are manufactured chemically to provide precise nutrient ratios. They work quickly and efficiently.
Specialised Fertilisers
Seasonal fertilisers – these lawn fertilisers are designed for seasonal suitability for spring, summer, autumn, or winter. Each has a nutrient composition suited to seasonal needs.
- Use a nitrogen-rich fertiliser in spring for optimising growth, such as KissMyGrass Premium Spring & Summer Lawn and Sportsfield Fertiliser 12.5.5+
- Use a potassium-rich formula in autumn to strengthen roots for winter, such as KissMyGrass Autumn & Winter Vitality Liquid Lawn Fertiliser
- Seasonal fertilisers are also available in liquid form for example KissMyGrass Spring and Summer Boost Liquid Lawn Fertiliser
Weed and feed – weed and feed fertilisers such as KissMyGrass All in One Lawn Treatment combine fertiliser with herbicides to nourish the lawn while controlling weeds.
Starter fertilisers – like KissMyGrass Pre-seeding Lawn and Sportsfield Fertiliser 6.9.6 are high in phosphorus to promote strong root development in newly seeded lawns.
How to Choose the Right Lawn Fertiliser
Test your soil – conduct a soil test to determine nutrient deficiencies and pH levels.
Identify your grass type – different grass species have varying nutrient requirements. Warm-season grasses need different fertilisation schedules compared to cool-season grasses.
How to Apply Lawn Fertilisers
Proper application ensures that fertiliser benefits the lawn without causing harm. Follow these best practices:
- Read the label – always follow manufacturer instructions for dosage and application frequency.
- Apply evenly – use a Lawn Spreader for granular fertilisers or a sprayer for liquid fertilisers to ensure even distribution.
- Water after application – lightly water the lawn after fertilising to help nutrients penetrate the soil.
- Avoid over-fertilising – excess fertiliser can burn grass, cause rapid, weak growth, and contribute to environmental pollution through runoff.
- Fertilise at the right time – early morning or late afternoon is ideal to prevent evaporation and ensure better absorption.
