Jargon Buster

• NPK Ratio: The three numbers displayed on fertiliser packaging indicating the percentage of Nitrogen (N), Phosphorus (P), and Potassium (K) – the three primary nutrients essential for plant growth. Different ratios suit different applications, with high nitrogen formulas promoting leaf growth whilst phosphorus supports root development and potassium enhances overall plant health.
• Systemic Weedkiller: A herbicide that is absorbed by the plant and transported through its vascular system to kill it from within, including the roots. This provides more thorough control than contact weedkillers, particularly for perennial weeds with deep root systems that would otherwise regrow.
• Selective Herbicide: A weed control product designed to target specific plant types (typically broad-leaved weeds) whilst leaving desired plants such as grass unharmed, making them ideal for lawn maintenance without damaging the turf.
• Monofilament vs Ryegrass: Terms describing different grass seed types – monofilament refers to fine-bladed ornamental varieties creating attractive lawns, whilst ryegrass varieties are hardwearing and quick to establish, suited to high-traffic areas and sports grounds.
• Biocide: A chemical substance designed to control harmful organisms, including algae, moss, and lichen. When used for patio and path cleaning, biocidal products not only clean surfaces but prevent rapid regrowth of organic matter that causes discolouration and slippery conditions.
• Slow-Release Fertiliser: A formulation that gradually releases nutrients over an extended period (typically 2-6 months), providing consistent feeding whilst reducing the risk of nutrient leaching and minimising the frequency of applications required throughout the growing season.

How to Choose the Right Chemicals & Fertilisers

Selecting appropriate products requires consideration of several key factors:

Application Type and Timing: Different chemicals serve distinct purposes – fertilisers promote growth, weedkillers eliminate unwanted plants, moss killers restore lawns and clean hard surfaces, whilst patio cleaners remove organic staining and algae. Seasonal timing is crucial, with spring fertilisers emphasising growth, summer feeds maintaining health, and autumn treatments preparing plants for winter. Always check product labels for recommended application periods to maximise effectiveness.

Area and Surface Type: Consider what you're treating – lawn fertilisers differ fundamentally from those for vegetable patches or ornamental borders. Similarly, weedkillers formulated for patios and paths aren't suitable for lawns, whilst specialist moss killers may target either turf or hard surfaces. Measure the area requiring treatment to calculate the correct quantity needed and ensure adequate coverage without waste.

Selective vs Non-Selective Treatments: When controlling weeds, selective herbicides target broad-leaved weeds whilst preserving grass, making them essential for lawn care. Non-selective weedkillers eliminate all vegetation, making them suitable for paths, driveways, and areas requiring complete clearance before replanting or landscaping work commences.

Formulation and Application Method: Products come in various forms including granules, liquid concentrates, ready-to-use sprays, and soluble powders. Consider your application equipment – do you have a suitable sprayer, spreader, or watering can? Liquid concentrates offer economy for larger areas when diluted correctly, whilst ready-to-use formats provide convenience for smaller jobs without mixing requirements.

Environmental Considerations: Modern formulations increasingly consider environmental impact. Look for products suitable for use around children, pets, and wildlife where appropriate. Check whether treatments are rainfast (resistant to washing off once dried) and consider organic or reduced-chemical alternatives where they meet your performance requirements.

Regulatory Compliance: Professional users must comply with COSHH regulations, maintain records of chemical applications, and ensure operators have appropriate training. Check that products are approved for professional use if applying as part of business operations, and follow all HSE guidelines regarding storage, handling, and disposal of chemical products.

Safety Information

Garden chemicals and fertilisers require careful handling to ensure user safety and environmental protection:

Personal Protection: Always wear appropriate PPE as specified on product labels, typically including chemical-resistant gloves and eye protection. Some products may require respiratory protection – consult the safety data sheet before use. Wash hands and exposed skin thoroughly after handling chemicals, even when wearing gloves, and never eat, drink, or smoke during application.

Storage and Handling: Store all chemicals in their original containers with labels intact, in a secure, dry location away from children, pets, food, and animal feed. Professional users must comply with COSHH regulations, maintaining an inventory and risk assessments for all substances. Never transfer chemicals to unlabelled containers, and keep products away from extreme temperatures which may affect their stability.

Application Safety: Follow manufacturer instructions precisely regarding dilution rates, application timing, and weather conditions. Avoid applying chemicals in windy conditions to prevent drift onto unintended areas. Many products specify minimum temperatures for effectiveness and maximum temperatures to prevent damage. Keep children and pets away from treated areas until products have dried or for the period specified on the label.

Environmental Responsibility: Prevent contamination of water sources, including ponds, streams, and drains. Never dispose of chemicals or washings down drains – follow local authority guidance for safe disposal. Use products responsibly, applying only the recommended quantities to avoid environmental damage and nutrient runoff. Consider timing applications to avoid periods when beneficial insects like bees are most active.

Emergency Procedures: Familiarise yourself with first aid measures detailed on product packaging before use. In case of accidental ingestion or significant exposure, seek medical attention immediately and take the product container or label with you. Keep emergency contact numbers readily available when working with chemicals professionally.

Frequently Asked Questions

When is the best time to apply lawn fertiliser in the UK?

For optimal results, apply spring fertiliser between March and May when grass begins active growth, summer feed from June to August to maintain health during the growing season, and autumn fertiliser from September to November to strengthen roots before winter. Avoid fertilising during frost, drought, or when rain is imminent, and always water in granular products if rainfall isn't forecast within 48 hours.

Can I use the same weedkiller on my lawn and patio?

No – lawn weedkillers are selective herbicides designed to kill broad-leaved weeds whilst leaving grass unharmed, making them unsuitable for total vegetation clearance. Patio and path weedkillers are typically non-selective, killing all plants they contact, which would damage or destroy your lawn. Always check product labels to ensure you're using the correct formulation for your specific application.

How do I calculate how much fertiliser or weedkiller I need?

Measure your lawn or treatment area in square metres (length × width), then check the product coverage rate specified on the packaging, usually given as grams per square metre for granular products or litres of diluted solution per square metre for liquids. Multiply your area by the application rate to determine total quantity needed. Many products include calibration guides for spreaders and sprayers to ensure accurate application rates.

Are garden chemicals safe to use around children and pets?

When used according to manufacturer instructions, approved garden chemicals pose minimal risk once dried or after the specified exclusion period. Most products require keeping children and pets off treated areas until surfaces are completely dry, typically 24-48 hours. Some modern formulations are specifically designed with reduced toxicity for faster safe re-entry. Always read and follow label instructions, and consider organic alternatives where children and pets frequently use garden areas.

Why isn't my moss killer or weedkiller working?

Several factors affect efficacy: applying during unsuitable weather (too cold, too hot, or rain washing product away before absorption), incorrect dilution rates, treating during the wrong season when plants aren't actively growing, or the target weeds being resistant to the active ingredient used. Moss killers require time to work – moss typically blackens over 2-3 weeks before being easily removed. Ensure you're following all application instructions and consider whether the product is appropriate for your specific weed or moss species.
