If the lawn is receiving adequate moisture studies have shown that a 50% slow release every 6 weeks gives the most even color and growth. I have one customer that has irrigation so I put down a 75% slow release within two weeks of Memorial day for my customers and then a 50% slow release around Labor Day. If it is less than 50% allow release I don't consider it a slow release, but that is just me. A 50% slow release will last up to 8 weeks depending on the polymer coating used and the amount of rain.
