Autumn Lawn Fertilisers: Prepare Your UK Grass for Winter

Why Autumn Fertilising Matters

Autumn is a critical period for UK lawns, as grass slows growth and prepares for winter dormancy. Applying autumn fertilisers strengthens roots, improves nutrient reserves, and enhances disease resistance, ensuring a healthy lawn come spring.

This guide is aimed at gardeners, landscapers, councils, estates, and sports facility managers, providing step-by-step advice on fertiliser selection, application, and maintenance.

Step 1: Choosing the Right Autumn Fertiliser

High-potassium formulations: Promote strong roots and winter resilience
Low-nitrogen mixes: Encourage root development rather than excessive leaf growth
Granular autumn fertilisers: Long-lasting, slow-release options
Sports turf mixes: Strengthen high-traffic areas such as football, rugby, and golf pitches

Pro Tip: GardenersSupplies.co.uk offers autumn-specific fertilisers suitable for lawns, estates, councils, and professional turf management.

Step 2: Timing Applications

Best time to apply: September–November, depending on soil temperature and weather.

Early autumn (Sept–Oct): Apply before the first frosts for maximum root absorption
Late autumn (Nov): Use only if soil is workable and not waterlogged
Avoid applying on frozen or excessively wet lawns to prevent damage

Step 3: Preparing Your Lawn

Mow beforehand: Slightly shorter grass ensures better fertiliser contact
Remove leaves and debris: Prevents blockage of granules and uneven feeding
Aerate compacted areas: Helps fertiliser penetrate to roots and reduces waterlogging
Check for moss or weeds: Treat with moss killer or spot weed control before fertilising

Step 4: How to Apply Autumn Fertiliser

Granular application: Use a rotary or drop spreader for even coverage
Follow application rates: Prevent overfeeding and nutrient runoff
Water lightly if needed: Ensures nutrients reach the soil
Safety: Wear gloves and follow product instructions carefully

Step 5: Aftercare Tips

Avoid heavy traffic: Grass is more vulnerable in autumn
Overseed bare patches: Combine with autumn fertiliser to repair thin areas
Monitor lawn condition: Look for early signs of moss, weeds, or disease
Prepare for winter: Maintain mowing and clean debris until the first frost

Frequently Asked Questions (FAQ)

Why use autumn fertiliser instead of spring/summer types?
Autumn fertilisers focus on root development and resilience rather than leaf growth, preparing grass for winter.

Can I apply after the first frost?
No, wait until soil is workable; frozen ground prevents absorption.

How often should autumn fertiliser be applied?
Typically once in autumn is sufficient; some areas may benefit from a light follow-up in late November if conditions are suitable.

Will fertiliser affect wildlife?
Modern autumn fertilisers are safe when applied according to label instructions.
