Nutrigrow 4-0-4+9Fe is ideal for autumn and winter use on any grassed area. This is a quality, fast acting spreadable compound fertiliser with 2-3mm uniform granules. While it is commonly used during the cooler periods, it can be used all year round if you require a lower nitrogen mix. The high iron content will green grass up without promoting top growth and will also blacken moss. Use Nutrigrow 4-0-4+9Fe at an average of 50g per m².

Treating grass in the autumn and winter is very important as it helps strengthen the grass while also offering pre-stress conditioning. Application during the cooler months also helps to reduce the threat of disease, moss & weeds by encouraging a denser sward.

The application rate will depend on how many times you intend to apply the product and also what the grass is going to be used for. Apply either by hand or through a fertiliser spreader.
