How it compares

How to use it

1. Shake the bottle thoroughly before use to ensure the organic matter is well-mixed.
2. Dilute 50ml of the concentrate into 9 litres of water using a standard watering can.
3. Apply evenly across the lawn surface during the growing season (March to October).
4. For best results, apply when the soil is moist or after light rainfall.
5. Repeat the application every 4 to 6 weeks to maintain a deep green colour.

As noted by Ethical Consumer (2024), plant-based fertilisers represent a significant step forward in reducing the carbon footprint of domestic gardening. Furthermore, similar organic treatments have been praised by Good Housekeeping UK (2024) for their ease of use and long-term benefit to garden ecosystems compared to quick-fix chemical salts.

FAQ

Is it safe for all grass types?

Yes, this organic liquid feed is suitable for all UK lawn types, including fine fescue, ryegrass, and bentgrass. Because it is made from natural plant materials, it works with the grass's biology rather than forcing growth, making it safe for both newly laid turf and established ornamental lawns throughout the spring and summer seasons.

Does it smell like traditional manure?

No, unlike animal-based organic fertilisers, PlantGrow has a mild, earthy scent that dissipates very quickly after application. It does not attract flies or vermin, making it a much more pleasant option for small urban gardens or patios where lingering odours from poultry manure or fish-based products would be undesirable.

How soon can my pets go back on the grass?

Immediately. Because the formula is 100% plant-based and contains no toxic chemicals, pesticides, or sharp granules, it is completely safe for cats, dogs, and even grazing pets like rabbits or tortoises. You do not need to water it in or wait for a specific period before allowing your family back onto the lawn.
