i just bought my first home and i went to weed n feed my lawn. i used scotts brand and a drop spreader. having never done this before i neglected to set the drop rate for my spreader and burned parts of my grass. there are streaks and patches of yellow/green lawn with lush green steaks where the weed n feed seems to have worked. does anyone know of way i can make my yellow/green grass look as good as the rest with out having to re seed my lawn? i don't know if i should weed n feed again or try some miracle gro.
