There are many variables regarding which fertilizer analysis is ‘best’ to use. Amount and type of fertilizer used depends on soil type, available irrigation…or precipitation, and the total amount of Nitrogen required per season to reach optimal turf quality. It is usually best to use fertilizer with ‘Slow Release Nitrogen’. Always read and follow label instructions for fertilizers, combination fertilizer and pesticide products, and other lawn pest control products. Above dates are estimates depending on weather. Apply all fertilizers to dry turf and water in, except granular ‘weed & feed’ applications.
