Controlled vs Slow Release FertilizerBoth slow and controlled release fertilizers are similar in that neither make nutrients available to grass all at once or over a short time-frame. The differ however in how that happens.

Controlled release uses special coatings typically to make the nutrient availability the same in each environment it is applied.

Should You Fertilize the Grass in the Summer?
Should You Fertilize Grass in the SummerThe summer is the slowest growth time of the year for cool season turf grasses like KGB, Fescues, and Rhy. Assuming the temperature doesn’t get too hot and irrigation remains high enough the grass will be green and growing but not with the same vigor as as does in the Spring and Fall. This is the reason why most lawn care professionals wait through this time of the year for a late summer application so as to not push the grass during naturally slow times. This article goes into the timing of all this in greater detail.
