Lawn Size
Lower Rate (1 litre covers up to 500m²) | For regular lawn maintenance and healthy lawns. |
Higher Rate (1 litre covers 250m²) | For stressed, patchy, or nutrient-deficient lawns needing extra support. |
Use the higher rate if your lawn is recovering from drought, heavy use, or poor soil conditions. For general upkeep, the lower rate will keep the soil and grass in good shape.
• Mix 200-400ml per 100m².
• Dilute in 3-5 litres of water per 100m²
• For best results, apply using a sprayer for even coverage
• A watering can can also be used, but may not provide as even distribution.
• Do not mow for 24 hours after application.
• Keep pets off the lawn during application and until dry.
• Avoid applying during drought conditions, extreme heat, or frost. For best results, apply when soil has moisture, such as after rainfall or watering.
For regular lawn maintenance
Apply once a month (every 4 weeks) all year round to keep soil healthy and grass strong.
For stressed or nutrient-deficient lawns
Apply every 1-4 weeks until the lawn improves. Use a higher concentration if the lawn is weak or patchy, then switch to monthly maintenance.
Winter Application
Can be applied in colder months to support soil health, but avoid use during frost or waterlogged conditions.
