Weed & Feed Application Instructions
A fertilizer and herbicide combination better known as “weed and feed” is applied to the entire lawn, regardless of the number of weeds and where they are located. While fertilizer contains nitrogen, phosphorus and potassium, the herbicide is a toxic substance designed to kill the existing weeds while preventing new ones from growing. This combination is available in pellets, powder and liquid form. It is most often applied any time weeds are visible and generally lasts for up to six weeks.
Details and Usage
Weed and feed formulas is applied to a wet lawn and the lawn is not mowed or watered for at least 24 hours. Application is best in spring or fall when the weeds are actively growing. It is not applied to lawns that are near water supplies, storm drains or drainage ditches. Most weed and feed combos actively kill dandelions and other major weeds that have strong, deep root systems. Each weed and feed package provides a list of exactly what plants it kills, along with application and frequency instructions.
Herbicides in Weed and Feed
Weed control products are available in several forms: selective, non-selective, contact and systemic. Selective herbicides knock down certain weed species without affecting the growth of other plants and most weed and feed combinations contain selective herbicides. Non-selective herbicides wipe out everything it touches. Contact herbicides will also kill plants on contact, but often leave the rhizomes intact to re-grow later. Systemic herbicides are absorbed and spread throughout the plant, killing it completely. Knowing what weeds you have is helpful when selecting the correct herbicides in your weed and feed product.
Fertilizers in Weed and Feed
Fertilizers are vitamins for your lawn and when properly applied, will enhance the look and growth of your grass or plants. Slow-release fertilizers feed plants gradually over a certain period. The essential elements of fertilizer are nitrogen, phosphorus and potassium, or N-P-K. Nitrogen promotes the green color and can be fast-acting, slow release or both. Phosphorus promotes root growth, while potassium helps the grass survive temperature extremes. Knowing your soil condition is helpful when selecting the correct fertilizer needed. A soil test kit, available at most large garden centers, can give you this information.
Weed and Feed Combinations
Weed and Feed products contain slow-release water soluble mixtures of dry lawn fertilizer and selective slow-release weed control formulas.

If you want to apply weed and feed to your yard, mow your lawn 2 to 4 days beforehand to ensure that the product will distribute evenly across your lawn. For the best results, plan to apply it in the spring and fall, when weeds are actively growing.
