Feed your lawn.

Whether you are looking for a one-off spring boost or a year-round seasonal treatment plan, hiring a specialist ensures the right balance of chemicals is applied at the correct time. This guide covers everything you need to know about the costs, processes, and benefits of professional lawn feeding.

What Does the Work Involve?

• Soil Assessment: Checking the lawn for moss, weeds, and nutrient deficiencies to determine the best fertiliser type.
• Preparation: Clearing debris and, if necessary, lightly scarifying or aerating the soil to ensure nutrients reach the roots.
• Product Selection: Choosing between granular or liquid fertilisers based on the season (e.g., high nitrogen for spring, high potassium for autumn).
• Calibrated Application: Using professional-grade spreaders to ensure an even coating and prevent "lawn burn" caused by over-concentration.
• Weed and Moss Control: Many fertilisers are applied as a "3-in-1" treatment that also targets broadleaf weeds and moss.
• Post-Treatment Advice: Guidance on watering schedules and when it is safe for children and pets to return to the grass.

Typical Costs

Prices for lawn fertilisation vary based on the size of your garden and the quality of the products used. Most UK gardeners charge a minimum call-out fee for small urban lawns, while larger rural properties are priced by square footage.

Factors affecting the price include the current condition of the lawn (heavily weed-infested lawns require stronger treatments), your location in the UK, and whether you opt for organic or synthetic fertilisers.

How Long Does It Take?

• Small Urban Garden: 30 to 45 minutes for a straightforward feed and weed application.
• Average Semi-Detached Garden: 1 to 1.5 hours, including preparation and equipment setup.
• Large Gardens/Manor Lawns: 2 to 4 hours, depending on the equipment used (tow-behind spreaders are faster than push spreaders).
• Full Renovation: 1 full day if fertilisation is combined with heavy scarification and overseeding.

DIY or Professional?

While you can buy boxes of "Feed and Weed" at any garden centre, DIY application often leads to "striping"—where uneven spreading leaves bright green lines next to yellow, burnt patches. Professional gardeners use calibrated equipment and have access to "professional-use only" fertilisers that are more effective and longer-lasting.

If your treatment includes professional-strength weedkillers or pesticides, the person applying them should hold a NPTC PA1/PA6 certificate by law.

Choosing the Right Tradesperson

• Check Qualifications: Look for members of the Lawn Care Association or gardeners with RHS Level 2 or 3 certifications.
• Insurance: Ensure they have Public Liability Insurance in case of accidental damage to your property or prize plants.
• Red Flags: Be wary of anyone who offers a "one size fits all" fertiliser year-round; different seasons require different nutrient ratios.

Questions to ask:

• Are your products safe for my pets and children?
• Do you use slow-release granules or liquid feed?
• Is moss control included in this price?
• What happens if it rains immediately after the application?

UK Regulations

• Pesticide Regulations: The use of professional-grade herbicides (often mixed with fertiliser) is governed by the Sustainable Use of Pesticides Regulations.
• Waste Disposal: If the gardener removes moss or thatch after treatment, they must hold a valid Waste Carrier Licence to transport it.
• COSHH: Professionals should be able to provide Control of Substances Hazardous to Health (COSHH) data sheets for the products they use.

Common Problems

• Fertiliser Burn: Applying too much product or applying it during a drought can scorch the grass, turning it brown or black.
• Uneven Growth: Poorly calibrated spreaders create a "patchwork" effect that can take weeks to grow out.
• Timing Issues: Applying nitrogen too late in the autumn can encourage soft growth that is easily killed by the first UK frost.
• Leaching: Using cheap, fast-release fertilisers before heavy rain can wash the nutrients away into the water table before the grass can absorb them.
