Weed & feed is a combination of minerals and systemic or non-systemic herbicides. The minerals provide nutrients (via fertilizer) to help your grass grow, while the herbicides kill the weeds.
Regardless of which one you choose, you must follow the directions on the container to get the best results. Certain herbicides are best for certain weeds, so be sure to read labels carefully when choosing a brand.
Many people choose liquid weed & feed because the chemicals are already diluted to safe levels. The liquid version may be bought in bulk or with an attached sprayer nozzle for convenience.
