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. [1] 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. [2] 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. [4] 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. [6] 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. [7] 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. [8] 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. [10] 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. [11] 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.

Weed And Feed Lawns: Where To Begin

Weed & Feed products combine a lawn fertilizer with a weed killer and/or weed preventer in one product. One application does double duty, treating random weeds spread across an entire lawn while also feeding and greening grass. Weed & Feeds come in two basic formulations, granules and liquids. But before you make an application, here are some things you need to know about weed & feed products.

Weed & Feed Starts With Weeding…

The “weed” half of “weed & feed” contains some mix of herbicides to kill lawn weeds. Almost all products contain a post-emergent herbicide, but some also combine a pre-emergent herbicide designed to prevent new weeds from sprouting.

Post-Emergent herbicides kill existing lawn weeds like Dandelion, Clover and many other common weeds. The complete list of weeds can be found on your product’s label. These post-emergents are always selective herbicides, so they will not harm existing grass when applied as directed. New innovations, like BioAdvanced 5-in-1 Weed & Feed, also kill grassy weeds like Crabgrass, eliminating the need for multiple applications of additional herbicides to achieve control.

Pre-Emergent herbicides are meant to keep new weeds from germinating and growing. Timing is the key, apply too early and the preventer can become ineffective while weeds are still dormant. Apply too late and seeds may have already germinated. You’re probably most familiar with Crabgrass preventers that are applied in early spring.

…And Ends With Feeding

The “feed” half of “weed & feed” is all about fertilizer. Most fertilizers are a mix of nitrogen and other macro-nutrients, and sometimes micro-nutrients, in varying amounts. Nitrogen (N) is the most important element in lawn fertilizers and comes in two basic forms – fast-release and slow-release. Most lawn fertilizers include a mix of fast-release and slow-release forms to provide quick green-up and sustained growth.

Fast-Release Nitrogen (often referred to as water-soluble nitrogen or WSN) such as urea and ammonium sulfate, is readily available and absorbed quickly by the grass, resulting in fast green-up. Unfortunately, it can also can burn your lawn if applied improperly, and can leach through the lawns root zone or run off the lawn in heavy rain, causing pollution.

Slow-Release Nitrogen (often referred to as WIN or water-insoluble nitrogen), such as sulfur-coated urea, methylene urea and animal manures, are released more slowly to the grass and provide more sustained, even growth – up to 3 months for methylene urea.

Before You Begin, Know Your Lawn Type

Before applying any type of weed & feed or fertilizer product, you need to identify your type of grass. Some fertilizers can be applied to all lawn types, but most weed & feed products are specifically labeled for certain types of grasses. Apply the wrong product to the wrong type of grass and you can damage your lawn. Use caution and read the label. If you’re still unsure, use the toll-free number found on the label to contact the manufacturer.

When To Apply

Weed & Feed products are most effective when weeds are small and actively-growing, namely spring and fall.

In spring, wait to apply until you’ve mowed your lawn two times before applying to be sure it has emerged from dormancy.

In fall, be sure to check the with local Cooperative Extension System office for historical frost dates in your area. Many Weed & Feed labels will recommend application timing based on that date.

Most weed & feed products will have temperature restrictions as well, be sure to check the label. Do not apply to water-saturated soils, lawns under stress from drought, disease or prone to injury.

How To Apply

For liquid weed & feed products, be sure to use one of the sprayer types recommended on the label and follow label instructions for mixing and spraying.

For granule weed & feeds, use a rotary or drop-type spreader. Drop spreaders apply fertilizer very precisely in a narrow band directly below the spreader, while a rotary spreader broadcasts over a wider area. The application pattern is very important. Be sure to follow label instructions.

Both types of spreaders have adjustable application settings. How much fertilizer is applied varies according to the settings on the type and model of spreader you use. Read the spreader manufacturer’s instructions before fertilizing to help you calibrate your equipment to ensure proper application rates. You’ll find the proper setting for your type of spreader on the specific fertilizer label. If not, there should be a toll-free phone number to call. Do not use the spreader until you are sure it is set properly. You can learn more about calibrating your spreader and spreader settings. Be sure to read always and follow label instructions.

Other Things You Should Know

Mowing – For best results, mow your lawn 1-2 days prior to application. Clippings from your next three mowings should be left on the lawn. Be sure not to use these clippings as mulch or compost around flowers, ornamentals, trees or in vegetable gardens.

Do Not Rake – Heavy raking will disturb the weed preventative barrier and reduce the effectiveness of this product.

Watering – Many weed & feed products instruct you to wait 24 hours before watering in. Be sure to consult your specific label.

Feeding New Lawns – Most new lawns don’t need to be fertilized until 6-8 weeks after planting. However, that can vary depending on how the soil was prepared before planting and the type of fertilizer used. Consult your local Cooperative Extension System office or nursery for recommendations on fertilizing new lawns.
