I use Winter Green Lawn Fertilizer as part of my annual lawn care programme and find it invaluable in helping maintain my lawns in good condition through the worst of the winter. I use it in partnership with Spring & Summer Fertilizer and Autumn Lawn Fertilizer to provide a year-round package of feed. This product will be useful for anyone wanting to keep their grass in good condition over the winter months.

Great product. Important to follow instructions re watering, time of year to apply and spreading evenly.

I find this to be an excellent winter fertiliser as it prevents moss growing even in very wet conditions and keeps the lawn looking good over the winter period.

I buy the winter high iron content feed for the cold wet months to keep some colour in the lawn and suppress moss growth. I buy the true fertiliser for growth when the weather warms in Spring. Both products excellent, can highly recommend.
