KissMyGrass Spring and Summer Boost Liquid Lawn Feed
An extremely effective and direct approach for an additional boost during the summer months. Working almost instantly, our Spring & Summer Liquid Fertiliser is a great addition to your regular granular routine for instant lawn revival to promote healthy, vibrant growth.
- Encourages healthy, vibrant growth
- Apply from March-August
- For best results, apply every 2-3 weeks
- Contains NPK at a ratio of: 16.2.8
- 1 litre covers 200sqm
1 litre covers 200sqm. Dilute as per the table below into a watering can or sprayer:
| Coverage | Fertiliser | Water |
| 20sqm | 0.1l | 1l |
| 50sqm | 0.25l | 1.25l |
| 100sqm | 0.5l | 2.5l |
| 200sqm | 1l | 5l |
Mix well before use. Apply evenly to the desired area. For best results, apply every 3-4 weeks, in addition to seasonal application of granular fertiliser.
Liquid fertiliser must be left to dry on the plants, meaning that if rain is imminent, it will wash it away or risk diluting it too much. Try and avoid fertilising the area after heavy rainfall - there will be too much water in the lawn in which the plants will struggle to take in the nutrients from the fertiliser. Avoid spraying in bright sunlight as this could result in scorching.

What is a liquid lawn fertiliser?
Liquid lawn fertiliser is a quick-release fertiliser that gets to work quickly and efficiently. They are great for giving your lawn a quick nutrient boost. Our spring and summer liquid lawn fertiliser is perfect for giving your lawn a nutrient boost to improve colour, growth and strength in time for or during summer.
How to use a liquid lawn fertiliser in the Spring/Summer?
Liquid fertiliser should be diluted with water before application as per the instructions on the package. Make sure to check the specific specifications for the product you’re using. Once diluted, we recommend applying with a watering can or sprayer for an even application.
Liquid fertiliser can be applied every 2-3 weeks as required. We recommend using it in combination with a granular fertiliser, such as our KissMyGrass Spring & Summer lawn granular fertiliser.
How long does it take for liquid lawn fertilisers to work?
Unlike slow release granular fertiliser, a liquid fertiliser should begin to work straight away, meaning you should begin to see results within a couple of days.
