Weed and feed products can be a useful tool for keeping weeds from germinating in your yard. For them to be effective, though, you need to ensure that you apply them at the right time. Spreading the product once every spring and fall can help keep certain weeds at bay. Be sure to check the forecast before applying, though, to avoid rain washing the product away.
Plan to apply it in the spring and fall. Weed and feed works best when applied when weeds are actively growing and the daytime temperatures are between 60° and 90° F (15.5° and 32.2° C). In most areas, this means applying once during the spring, and once during the fall.  X Research source
Mow your lawn 2-4 days before you apply. If you can, mow your lawn to a medium height 2-4 days before you plan to apply weed and feed. This helps ensure that the product is evenly distributed throughout your lawn.  X Research source
- The forecast should be clear for at least 24 hours for weed and feed to work correctly. You are also going to need to avoid watering your lawn during this period.
- Do not try to apply the product immediately after a heavy rain, either. Standing water in your lawn could wash away the particles.
Wet your lawn before applying. Use a misting or a low-pressure setting to lightly wet your lawn immediately before applying. You want your grass to be damp to the touch, but with no quick-draining or standing water. It should be just wet enough to help the product stick to the blades of grass.  X Research source
- If you do not already own a spreader, you can buy one at a home and garden store or online for under $30 USD.
Apply the product to your lawn. Once you have the product loaded and your spreader set, you can begin applying the product on your lawn. Get the best coverage by walking linear passes along the length of your lawn while disbursing the product from your spreader. Walking in straight lines ensures the most even coverage.  X Research source
Overlap your passes to improve your coverage. To help ensure that all your lawn receives an even amount of the product, overlap your passes slightly. Walk on the edge of your last pass. You should be able to see the product on the lawn to help guide you. This helps prevent any untreated spots.  X Research source
Sweep or rake any excess product off of sidewalks and driveways. Use a broom or a rake to push excess product from any sidewalks, driveways, or roads back into your yard. This keeps unused product from washing away in storm drains.  X Research source
- If a pet or child ingests any weed and feed, call a vet or a doctor immediately to get recommendations for treatment options.
Avoid watering your lawn for at least 24 hours. Washing your lawn too quickly after you apply weed and feed could wash away the product before it has a chance to work. Wait at least 24 hours before watering your lawn. Some products recommend waiting up to 2-4 days before watering. Check your specific product’s instructions to get the most accurate recommendation.  X Research source
Wait 4 weeks to reseed and aerate your lawn. Weed and feed can prevent seeds from germinating, so it’s important to make sure the product is fully absorbed before you plant new seeds or aerate your lawn. Wait at least 4 weeks after the date you applied the product to start reseeding or to aerate the treated areas.  X Research source

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. Weed and feed is most often used on established lawns, as this mixture can easily overwhelm young grass. Weed and feed products should only be used when you actually have a weed problem, otherwise a fertilizer is all you need.
