I have frequently contacted Scotts directly using the email contact within the app. They have provided me with great information on products and even composed a custom yearly timeline with application dates and products specifically for my location. Dont ask the store clerk what they suggest, ask Scotts directly. Applying the wrong product may prevent you to apply seed for the entire season or damage your lawn.
