How to apply weed and feed

Scotts has two different weed and feed products: Scotts Lawn Pro Super Turf Builder with Plus 2 Weed Control, and Scotts Super Bonus S Weed and Feed. (As with other chemical lawn applications you must be sure to follow the manufacturer’s directions). Weed and feed does just that–it feeds the lawn to promote root growth and lawn density, and also kills dandelions and other lawn weeds. Scotts Plus 2 should only be used twice during the growing season, and when dandelions and other lawn weeds are growing. The Super Bonus can be applied anytime weeds are growing. Be sure to read the packaging label as both products can be harmful to certain types of grass and should not be used on them.

Check the weather forecast before applying the Scotts product. Rain should not be forecasted for at least 24 hours after applying the fertilizer. Do not water your lawn for 24 hours after applying the weed and feed. Also, the fertilizer should be applied when there is little or no wind–otherwise there is a possibility that the fertilizer will be blown on plants and shrubs.

Check the grass to make sure that it is slightly wet from the morning dew. If the grass is dry you will need to sprinkle it lightly before applying the fertilizer. The moisture enables the fertilizer to stick to the blades of grass and to the weeds.

Set the gauge on the spreader according to the setting gauge chart on the bag of Scotts Weed and Feed. There are two types of spreaders, rotary or broadcast spreaders and drop spreaders. The spreaders have settings on them to control how much fertilizer is dropped. The correct setting will be listed on the fertilizer bag.

Fill the hopper with fertilizer. Fill it while on a sidewalk or driveway as you do not want to get a concentrated amount of fertilizer on the lawn should you spill some.

Apply the fertilizer following the directions on your spreader. Do not overlap your application as it will apply too much fertilizer in one area and there is a possibility of burning the grass. Do not stop in one spot with the release lever open, as this will also send a concentrated amount of fertilizer in one spot–burning the grass.

When the lawn is complete, sweep away any fertilizer that has gotten on the sidewalk or driveway. Also, rinse out your spreader and allow it to dry.

  • Do not overlap your application as it will apply too much fertilizer in one area and there is a possibility of burning the grass.

Wash your hands thoroughly after working with fertilizer. Grass should not touch the bottom of the spreader when applying the fertilizer. Therefore, be sure to mow any tall grass before putting down the weed and feed. Do not apply to newly seeded lawns.

Keep children and pets off of the grass after applying fertilizer for at least 24 hours (until after you water the lawn).

Using a weed and feed product in the fall will help control broadleaf weeds and keep your lawn green throughout the season. The success of using the product depends on taking the correct steps to ensure the proper absorption of the herbicide and fertilizer. The weed killer in the product works to kill active young weeds. The fertilizer is often a type of quick release nitrogen that will green up the lawn and create an environment in the soil for healthy growth of leaves. Apply weed and feed only once a year; feed your lawn more often.

Watch weather reports and plan to spread your weed and feed when there will be no rain for a few days afterward. You should also watch for hot spells as you will not be able to water for a few days. Mow the lawn two to three days before the planned time.

  • Using a weed and feed product in the fall will help control broadleaf weeds and keep your lawn green throughout the season.

Wet the lawn just prior to spreading the weed and feed. This will help hydrate the weeds so the weed killer will be more readily absorbed. It will also help the weed killer to stick to the leaves.

Place the weed and feed into a dry, clean spreader. Follow the manufacturer’s recommendations on how much to use per square foot of lawn.

Set the application rate on the spreader according to the manufacturer’s directions. Do this by turning the application rate dial to the correct number.

  • Wet the lawn just prior to spreading the weed and feed.

Spread over the lawn in a uniform manner. If your spreader does not have an edge guard, be careful not to allow the weed and feed to cast into your flowers, shrubs or sidewalks. Weed killers can kill flowers, damage shrubs and leave hard-to -remove stains on your sidewalks and driveways.

Do not water the lawn for at least two days after application or you may wash off the weed killer before it does its job.

Do not aerate for at least two weeks or plant any new grass seed for at least 4 weeks.

You’ve heard the expression that an ounce of prevention is worth a pound of cure. Nowhere is that more true than with weed control. Weed preventers, also called pre-emergents, are an easy, effective way to stop weeds before they start growing. But they can only do that if you apply them with the correct timing.

Product packages usually provide a general guide to application timing. For example, they’ll tell you approximately when you need to apply a crabgrass preventer. However, regional and year-to-year weather variations can make correct timing tricky. Fortunately, there are some easy ways to time your applications to get the most out of them. The best-known method is to time crabgrass preventers for your lawn according to forsythia bloom. This popular landscape shrub is grown for its striking yellow bloom in early spring. When most trees and shrubs are still bare, you can’t miss forsythia when it flowers. When the blossoms start to drop to the ground, it’s time to put down the crabgrass preventer. For garden beds, the timing depends on the primary target weed. If you are dealing with cool season weeds, such as henbit or chickweed, then apply a garden weed preventer as soon as soil can be worked in spring. However, summer weeds like crabgrass, foxtail, or spurge are your bane (as they are for most gardeners) time the application with forsythia bloom, as you would do with a lawn application. Resist the urge to apply too soon; weed preventers have a limited life span in soil, and the sooner you apply them, the sooner they wear out. 8-12 weeks is the typical length of effectiveness.

How to Apply Weed Preventer Most residential weed preventers are granular products, meaning that you apply them with a spreader. It’s important to apply at the rate stated on the product package. Also, granular products usually don’t work well unless they’re watered in with a half-inch or so of water. If no rain is expected in the week or so after application, consider irrigating to activate the weed preventer.

What to Apply to Prevent Weeds For lawns, there are several synthetic weed preventers that work well, and are sold under recognized brand names such as Bayer, Scotts, and many others. These are typically combined with fertilizer so that both can be applied at once, saving you a separate application for fertilizer. For garden beds, these products often are sold strictly as weed preventers (i.e. no fertilizer is included). Preen is one widely used brand for garden beds. An organic weed preventer option is corn gluten, which is nearly as effective as conventional products. Many brands of synthetic weed preventers also have corn gluten weed preventers in their product lines.

Precautions Weed preventers stop seeds from germinating. That means you should not apply them anywhere you want to plant flower seeds during the following 3 months, or in lawns where you’ve just reseeded (or plan to). However, you can use weed preventers in spring and plant seed in fall without any trouble. Remember that weed preventers don’t kill weeds that are already growing. Perennial weeds such as wiregrass, dandelions and many others will return each year unless you physically remove them or spray with a herbicide such as glyphosate (Roundup).

Applying a weed and feed too often can ruin your lawn, so it’s wise to be cautious when using these lawn-care products. It’s the herbicide portion of the ingredients that’s the main problem. If the weed-destroying chemicals build up, they can also harm turfgrasses. Wait at least two months before reapplying a weed and feed and don’t apply the product more than twice per year. Read the product label carefully and follow the instructions.

What Is Weed and Feed?

Weed and feed is a two-in-one lawn-care product that contains either a pre-emergent herbicide or a post-emergent herbicide. All weed and feed also contains lawn fertilizer. Pre-emergent herbicides help prevent crabgrass and broadleaf weed seeds from sprouting, while post-emergent herbicides destroy broadleaf weeds that are already growing in the lawn.

When to Apply Weed and Feed

Early spring before weeds appear is the best time to apply weed and feed that contains pre-emergent herbicide. If weeds have already appeared in the lawn, a pre-emergent herbicide won’t have any effect on them. On the other hand, weed and feed that contains post-emergent herbicide is only effective if applied to lawns that are already infested with weeds. What this means in practice is that post-emergent weed and feed can be applied from late spring onward.

How to Apply Weed and Feed

Apply weed and feed when the temperature is below 80 F, but above freezing, a day or two after mowing the lawn to its normal height. A product containing a pre-emergent herbicide is applied to a dry lawn. If rain doesn’t fall within the following three days, irrigate the lawn thoroughly to activate the herbicide. A post-emergent weed and feed works best when applied to a wet lawn so that the granules stick to the weeds’ leaves. However, rainfall washes the granules off the leaves, so wait until no rain is forecast for several days and water your lawn before applying the product. To obtain an even distribution when applying weed and feed, use a lawn spreader. Don’t allow children or animals on the lawn while weed and feed granules remain visible to avoid contact with the herbicide.

Warning

Don’t apply weed and feed to a newly seeded lawn. Wait until the lawn has been mowed at least twice.

Problems With Using Weed and Feed

It can be tricky to get the timing right when you want to use weed and feed on your lawn. The grass might not benefit from a fertilizer at the time when the herbicide must be applied. In early spring, the right time to apply a pre-emergent herbicide, a dose of fertilizer encourages lush, green growth, but the grass benefits more from root development to help it grow well over the coming summer. Similarly, post-emergent herbicides are most effective if applied in late fall when broadleaf weeds are storing nutrients in their roots, yet a better time to apply fertilizer would be early or late summer.

It may take up to 14 days to see full weed-killing results from Scotts Weed and Feed. However, the effects of the fertilizer component in the weed and feed will begin to work in as little as 1–5 days, with additional results for several weeks afterward.

The active ingredients in Scotts Turf Builder Weed and Feed are Dicamba and Mecropop, which are both post-emergent herbicides that attack established weeds in your lawn without harming the grass. These herbicides work by attacking plant systems to kill weeds down to the root. This process takes time but yields great results.

How to Apply Scotts Weed and Feed for Best Results

To get the most out of your weed and feed, it’s essential to apply the product to your lawn at the right time and under the right conditions. Scotts Turf Builder Weed and Feed performs best when applied according to these guidelines:

  • Temperatures are 60–90℉.
  • The lawn is damp (from dew or light sprinkling) but not wet.
  • A lawn spreader is used to evenly distribute the product.
  • Do not water the lawn for 24 hours after application.
  • Avoid mowing for 48 hours after application.

A damp lawn provides the best surface for the herbicide to stick to weed leaves, which helps the weed control product infiltrate the plants and begin killing them. This provides a huge boost in its effectiveness. Just make sure your lawn isn’t so wet that the product washes away.

Signs Scotts Weed and Feed is Working

How will you know if your lawn care mission was a success? In order to determine if your Scott’s Weed and Feed application is delivering results, look for these signs:

  • 1–5 Days: Greener grass that appears to be growing thicker and faster.
  • 7 Days: Initial yellowing and wilting of weeds in the grass.
  • 14 Days: Most weeds in the lawn are brown, dead, and easily pulled out by hand.
  • 30 Days: Most broadleaf weeds in the lawn are dead. The grass is much more green and lush than before.

By following the application for Scotts Weed and Feed, you will initially see your grass growth surge as broadleaf weeds begin to wilt. Over time, the weeds will die as the grass grows thicker, taking over places where weeds previously grew.

How Long Does Scotts Weed and Feed Take to Absorb?

It can take up to 24 hours for Scotts Weed and Feed to be completely absorbed into weed systems. This is the reason it’s important to avoid watering and/or mowing shortly after applying weed and feed.

Although most of the herbicides in Scotts Turf Builder Weed and Feed are absorbed within 24 hours, the chemicals still require time to work their way through the plant and kill it. Just because the herbicide has been absorbed doesn’t mean it’s done working. Remain patient as the product works to wipe out weeds.

Can You Water after Spreading Weed and Feed?

Wait 24 hours before watering your lawn after spreading Scotts Weed and Feed. If you water too soon after application, you risk washing the herbicide off plant leaves. Watering too soon after application can seriously diminish the effectiveness of the product.

  • Avoid watering for 24 hours after spreading weed and feed.
  • Do not spread weed and feed if rain is forecasted to fall within 24 hours.
  • Water the day before spreading weed and feed, to ensure the lawn is damp but not wet.

Rain can wash away your weed control product just like a lawn sprinkler. If rain is likely to fall within 24 hours of applying weed and feed to your yard, wait to apply another day. If you’re worried about your lawn drying out, water the day before spreading weed and feed. This will keep the lawn moist, causing the weed and feed to stick to plant leaves and maintain grass health.

How Soon Can You Mow after Spreading Weed and Feed?

Allow 48 hours to pass after weed and feed application before mowing a lawn. Mowing can not only unevenly distribute fertilizer and herbicide, it can even throw weed and feed into garden areas, where the herbicide ingredients can harm vegetables and flowering plants.

  • Wait 48 hours before mowing.
  • Mowing too soon can spread weed and feed onto garden plants, potentially killing them.
  • Fertilizer may be spread unevenly by mowing.

The fertilizer in Scotts Turf Builder Weed and Feed performs best when allowed a full 48 hours to break down and enter the soil. For best results in killing weeds and building a healthier lawn, hold off on mowing after application.

How Soon Will Scotts Weed and Feed Show Results?

Scotts Turf Builder Weed and Feed does two things at once: feeds your yard and kills weeds. You will begin to see a greener, healthier grass in 1–5 days, with full results in 4–6 weeks. On the weed control front, Scotts will begin to kill weeds within 7 days but will show complete results in 14 days.

When applied correctly, weed and feed will deliver a big impact by both killing weeds and boosting your lawn’s performance. All it requires is patience and correct application to get the most out of the product.

How to apply weed and feed

As soon as the winter months are over, legions of homeowners rush outside to check how their lawns survived the cold. Most of them will head inside with disappointment. If you are among the majority of Americans with sad-looking lawns this spring, you may already be planning to wake it up with a quick application of weed and feed over the weekend. But before taking the trip to your local garden store to pick up a few bottles, there are several good reasons why using weed and feed now may not be the best idea for the health of your grass. It is important to know when to apply weed and feed.

What is Weed and Feed?

The term “weed and feed” is a general term for a number of products. Most of these products combine post-emergent broadleaf herbicides to kill weeds such as dandelions and clovers with fertilizers to give your lawn a quick dose of the nutrients it needs after a tough winter. Weed and feed products are produced by most major lawn care manufacturers and come as a ready-to-go liquid or in a dry granular form.

Deciding When to Apply Weed and Feed

Timing is everything when it comes to lawn care. If you apply weed and feed too early, you risk the chance that you will miss attacking the weeds that have not yet started to grow, and they will survive the application. But, on the other hand, if you wait too long, your grass won’t get the nutrition it needs to grow well. The ideal time to apply weed and feed is in the early spring, just about the same time that you notice your lawn needs the first trim of the season.

Besides choosing the best time of the year to apply weed and feed to your lawn, you need to keep an eye on the weekly weather forecast as well. Avoid treating your lawn with weed and feed when the weatherman predicts rain is on the way. A spring storm shortly after an application will dilute the herbicide too much to be effective. If a surprise downpour does happen to catch you off-guard, you should not reapply the treatment because you will then risk overfeeding your lawn.

Tips For Success with Your Weed and Feed Application

Even when you choose the perfect time and weather for a weed and feed treatment, things can still go wrong. You can increase the chance of a successful application by following these tips:

  • Your grass should be between 3 to 5 inches tall.
  • Use a sprinkler to moisten your lawn lightly before applying the weed and feed treatment.
  • Don’t water your lawn for 48 hours using weed and feed.
  • Follow the manufacturer’s instructions to avoid over treating your lawn.

How to apply weed and feed

Weed and feed provides a wide range of lawn chemicals that are used to kill weeds and strengthen the existing grass. These products are highly preferred since they save you the hustle of using herbicides and applying fertilizers separately.

The weed and feed chemical does the work of both at the same time and will help improve your lawn’s ability to retain water and nutrients. For the products to be effective, they have to be applied at the right time.

I often get questions on whether it is advisable to use weed and feed before the rain, from both garden lovers and lawn care providers, and the answer to this question can be understood by illustrating the relation between rain and these chemical products.

What are Weed and Feed Chemicals?

Weed and feed are lawn chemical products that are designed to strengthen the ability of your lawn to absorb water and nutrients that will promote its growth.

How to apply weed and feed

Although different weed & feed products will have varying nutrient quantity, they are all rich in nitrogen to boost the growth.

They are a mixture of a variety of broad leaf-targeted herbicide, and they contain a water-soluble fertilizer; the herbicide contains chemicals such as dicamba and mecoprop. The herbicides eliminate the broadleaf weeds without harming the grass.

For the nutrients such as phosphorous and nitrogen to be absorbed, your lawn requires moisture. However, it is essential to keep in mind that excess moisture will wash away the chemicals. This is one of the main reasons why you should not apply your weed and feed before a rain.

When is the Right Time to Apply Weed and Feed?

Weed & feed are more effective when applied when the weeds are actively growing. You should also choose a time when you don’t expect additional rain in the next two or three days.

This will give more time for the herbicide to be absorbed into the leaves. If it rains after applying the chemicals, the chemicals will not be effective since they will be drained away.

How to apply weed and feed

In case it rains immediately after spraying the herbicide, it is advisable to take some time (4-6 days) before applying again since applying immediately might cause chemical scorch.

How to Apply Weed and Feed Before Rain

Before applying the weed and feed, make a point of checking the weather forecast. The last thing you would want is to have all your chemicals washed in the drain and leave the weed getting longer.

There are a few tips that will help you to apply the weed and feed effectively. However, these tips are not meant to replace the manufacturers’ instructions.

  • Trim your lawn to a normal height before applying the chemicals (3-5 inches will be perfect)
  • Don’t spray immediately after mowing. Wait for at least 2-4 days so as to protect the grass and to ensure that the weed will have actively resumed growing.
  • After application, don’t water the lawn for about 2-4 days and
  • Follow the manufacturers’ instructions on the number of granules to use. Too much of the chemical will scorch your lawn.
  • Apply the weed & feed only twice a year to minimize pollution of the soil and the surrounding environment. Some of these weed and feed herbicides include; Scotts Turf Builder Weed & Feed and Pennington Signature Series Weed and Feed Northern Fertilizer
  • Spread the herbicide evenly across the lawn for better results. You can use a broadcast spreader and make two passes or whichever your preference. Just make sure that every portion receives the same amount.

Applying the Weed & Feed after the Rain

If you were planning to spray your lawn after the rains, then it is recommendable to wait until the grass blades are dry. You should also ensure that the soil has sufficient moisture.

Ensure that there are no harsh winds when spraying since the chemicals can spread to other unintended plants or flowers near your yawn.

Safety Measures

  • When applying these chemicals, you should observe the standard precautions followed when applying any other herbicide.
  • Wear long pants and long sleeves and gloves during the application. Herbicides like Dicamba can cause skin irritation
  • Avoid eye contact and in the case where you get the product in your eyes, flush it out using running water

Final Verdict

From the above discussion, it is clear that by applying the weed and feed before rain, it will give time for the nutrients to be absorbed by the soil. More so, the leaves of the weeds will absorb the chemicals and dry out.

These chemicals are harmful and could have severe environmental side effects if not properly handled.

For example, when washed away by the rains, they will end up in the water catchment sources such as lakes, rivers, and streams.

This will reduce the oxygen levels for the fish and other aquatic animals. It is, therefore, crucial to use the weed and feed chemicals as instructed.
