The Ultimate Guide to Lawn Fertilisers in the UK: Spring & Summer Care

The Ultimate Guide to Lawn Fertilisers in the UK: Spring & Summer Care

Maintaining a lush, healthy lawn during the spring and summer months requires the right fertiliser strategy. Fertilisers provide essential nutrients—nitrogen, phosphorus, and potassium—that promote strong roots, vibrant colour, and weed-free growth.

Whether you are a gardener, landscaper, council grounds team, or manage sports facilities, understanding how to choose and apply the right fertiliser ensures optimum results for your lawn or turf.

This guide provides step-by-step advice on fertiliser types, application timing, and maintenance, with product suggestions from GardenersSupplies.co.uk.

Why Fertilising is Essential

  • Promotes growth: Nitrogen-rich fertilisers stimulate lush green shoots

  • Strengthens roots: Phosphorus encourages deep root development

  • Improves resilience: Potassium helps lawns withstand drought, wear, and disease

  • Controls moss and weeds: Combined formulations target moss and broadleaf weeds

  • Prepares turf for sports: Ensures even, dense grass surfaces for football, rugby, and golf

Step 1: Choosing the Right Fertiliser

Granular Fertilisers:

  • Easy to apply with a spreader

  • Slow-release options for long-term feeding

  • Suitable for home gardens, councils, and estates

Weed & Feed:

  • Combines fertiliser with selective weed control

  • Controls dandelions, clover, and other broadleaf weeds

  • Ideal for lawns with weed pressure during spring and early summer

Moss Killer Fertilisers:

  • Granular products target moss while feeding the grass

  • Suitable for shaded or damp areas prone to moss

Sports Turf Fertilisers:

  • High-performance formulations for football pitches, golf courses, rugby fields, and tennis courts

  • Promotes dense, resilient turf capable of heavy foot traffic

Pro Tip: GardenersSupplies.co.uk offers a full range of granular, weed & feed, moss killer, and sports turf fertilisers suitable for all UK lawns and gardens.

Step 2: Timing Your Fertiliser Applications

Spring (March–May):

  • Apply a nitrogen-rich fertiliser to stimulate early growth

  • Use weed & feed products when weeds are actively growing

Summer (June–August):

  • Apply balanced fertilisers to maintain lush colour

  • Use moss killer or lawn conditioner products if moss is present

Autumn (Sept–Nov):

  • Prepare lawn for winter with high-potassium formulations

  • Strengthens roots and enhances disease resistance

Step 3: How to Apply Fertiliser

  • Measure the area: Calculate the square meters to ensure correct application rate

  • Spread evenly: Use a rotary or drop spreader for consistent coverage

  • Water in: Light watering helps granules dissolve and penetrate the soil

  • Avoid overlap: Prevent burning or uneven growth

  • Timing: Apply during calm weather to reduce drift and ensure nutrient absorption

Pro Tip: GardenersSupplies.co.uk provides handheld and push spreaders for precise fertiliser application.

Step 4: Lawn Care Tips for Maximum Effect

  • Mow regularly: Maintain optimal grass height for your grass type

  • Aerate soil: Improves nutrient penetration and root growth

  • Overseed bare patches: Combine fertiliser with reseeding for a thick, even lawn

  • Monitor weeds and moss: Spot-treat areas that require additional attention

Step 5: Benefits of Using Quality Fertilisers

  • Vibrant lawns: Deep green, healthy grass

  • Weed and moss control: Reduces competition for nutrients

  • Stronger turf: Improved root system and drought resistance

  • Professional results: Suitable for high-use sports pitches and estates

  • Time-saving: Long-release formulations reduce frequent applications

Will fertiliser damage my lawn if I apply too much?
Yes, over-application can burn grass. Always follow the product’s recommended rate.
