Unfortunately you did not indicate what type of grass you have or what region you are located in, so we cannot provide you with a specific answer. Please take a few minutes to read over the Tupersan product label to find the application timing that fits your needs. You can find this information on page 3 of the product label. We have linked the product label in this answer for your convenience but you can always find product labels on the individual product pages for every product on our site.
