Easy-Open Resealable Tub

How to Use
Simply refer to the suggested usage on the reverse of the tub, dissolve your chosen amount of solution into water and apply via watering can or sprayer onto your grass.
Mix 1-2g of Iron Sulphate per 1L of water. 1L of the solution will cover 1m² of grass.
Increase the concentration and not only will it have an amazing effect on the greenness of your grass but it will also start to ‘harden’ the turf making it more resistant to disease and fungal attack. This makes it a very common practice on sports turf in autumn and winter. For hardening, we recommend applying between September and April when plenty of moisture is available and when sunshine is unlikely.
Mix 2-3g of Iron Sulphate per 1L of water. 1L of the solution will cover 1m² of grass.
