Up to Twice Per Year
Apply weed and feed to a damp yard once a year in the spring when you see weeds begin to grow. It may be applied another time during the same growing season if needed, according to The Scotts MiracleGro Co.'s website.
As Rarely as Possible
Weed and feed damages shrubs, flowers, trees and some grass species, according to a Louisiana State University Agricultural Center Research and Extension website article. Many herbicides work better in spray form as opposed to granular products. Weed and feed should not be applied to areas where both fertilization and weed control are not actually needed.
Use weed and feed products on a lawn no more than two times per year. Avoid other plants and flowers during application, and apply in localized areas only as needed. Always read the product's label prior to application to ensure that the product is appropriate for your lawn type.
