  • Damaged Lawns – If the grass and the soil have borne the brunt of a dry and cold winter, you might want to replenish it with Big-Small-Big combination, which will aid repair and protect it from further damage.

A word of caution would be to avoid going for the combination with high levels of phosphorus as it is not a very eco-friendly option.
