Scotts Lawn Pro Lawn Fertilizer helps you grow a thicker, greener lawn. This versatile fertilizer can be applied in the spring (March-April), late spring (May-June), late summer (August-September) or late fall (October-November) with a two-month interval between applications. You can also make this treatment part of a Scotts Annual Program and enjoy ideal results all year long. Apply this lawn food to a dry lawn with a Scotts broadcast, drop or rotary spreader and then immediately water the treated area. Please note that there is the possibility that staining may occur with this product during its application, particularly to cement, stone, metallic surfaces (such as automobiles and garden furniture) and clothing (including shoes). To minimize the chance of staining, brush any particles off of these surfaces and back into the area to be treated as soon as possible.
