to my lawn?
In the spring, early summer and late fall. The best time to spray your grass is in the morning when it’s cool. Weed-and-feed products are not good for cool weather so you will need to wait until after this time of year. You can also try applying weed and feed during cooler evenings or even overnight if necessary, but again be sure to apply in the morning when it’s cool(er). It may seem counterintuitive, but spraying insecticide on warm days is more effective than doing it at night because warm temperatures kill insects that may have laid eggs by daybreak!
