Always read label on chemical controls for the particular product you are using. Here is a link to the Preen product labels and directions. https://www.preen.com/sds

"Rain does not wash this product out of the soil. To keep ornamental beds weed-free all season long, reapply this product every 9-12 weeks."
Be sure to look for a temperature range and season on the label information as well.
