Sinclair Professional Sulphate of Iron provides long term, slow release iron nutrition to flowers and shrubs.
Iron is helpful in breaking down soil structure and maximising plant nutrient and mineral absorption. In particular, acid loving plants, such as Rhododendrons, Azaleas and Hydrangeas will benefit more after improving the pH level of the soil and better adapt to growing conditions.
This fertiliser can also be used as a lawn conditioner too. The nutrients in Sulphate of Iron work through absorbing into the soil when wet.
