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.

  • 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.

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.

Maintaining a beautiful lawn and garden year-round is easy with Scotts lawn care products. To support lush, healthy growth, homeowners should know which lawn care products to use and when to apply them. Do most people or gardeners ask how often to apply Scotts Weed and Feed? So, Plan your lawn care activities according to your area’s weather conditions to stay on top of the product applications.

Guidelines For Every Step

When you use Best Weed and Feed on your lawn, you must plan when and how to apply it. Apply Scotts Turf Builder Weed and Feed per these guidelines for best results:

Set Up A Lawn Care Program

When creating a lawn care program, you must consider more than just your locality. Lawn care is determined by the type of grass you have and the amount of sunlight and shade it receives, as well as the watering schedule and rainfall frequency in your region.

Meteorological Forecasts

You should apply Scotts’ products based on the weather forecast. Rain must wait at least 24 hours after fertilizer application. The lawn should not be watered quickly following the use of weed-killer and feed. In addition, fertilizer needs to be applied when the wind is few or nonexistent; otherwise, the fertilizer can blow all over the plants.

Scott’s Weed And Feed

  • In addition to Scott’s Super Turf Builder with Plus 2 weed control, Scott’s offers two other great weed and feed control products: Scott’s Super Bonus S Weed and Feed.
  • Scott’s Plus 2 must be applied twice during the growing season and around dandelions and other lawn weeds.

Fill The Hopper

Fertilizer should be added to the hopper. If you spill some fertilizer, you do not want it to land on the lawn since you will get a whole yard.

Using your spreader, apply the fertilizer as directed. Applying fertilizer in the same area twice will be too much in one place, causing the grass to burn. The release lever should not remain open in one spot while applying fertilizer, as this will burn the grass.


To dissolve properly and prevent fertilizer burn, each lawn product requires plenty of water. It is always best to follow guidelines for handling and application.

Tips And Tricks

After working with fertilizer, make sure to wash your hands thoroughly. While spreading fertilizer, you should not let the grass touch the bottom of the spreader. Thus, mow the tall grass before putting down weed and feed. Could you not use it on freshly seeded lawns?

Whether you’re an experienced hand in the garden or a novice, there’s one thing we all aspire to achieve, and that’s a beautiful luscious weed-free lawn. But as you may have already come to realize to achieve it we need to find a high-quality lawn fertilizer and a great herbicide to get on top of weed control.

That’s where a 2-in-1 weed and feed comes into play, feeding our lawn and dealing with weeds at the same time. But which one to choose, as there are so many products offering various solutions, that need applying in different ways, right!.

To help make the right choice, I have reviewed the best weed and feed products from the top brands, and I will show you how to use them to maximum effect. It’s doesn’t have to be complicated, so read on and we will get your lawn looking the best on the block.

When To Apply Weed and Feed

To get the most out of your 2-in-1 product, you need to get the timing right. As a general rule of thumb, apply weed and feed in the active season from April through to August.

Don’t go too early, the idea is that you kill off developing weeds. Also, consider the ‘feed’ element. This part is there to support healthy grass growth, top green foliage, but also a good root system. Applying too early will lead to a huge rush to top growth a limit root production. The result – more mowing, and weaker grass.

While keeping weeds out of your lawn can be a yearly struggle, with a comprehensive strategy, you can keep your lawn green and weed-free. Any weed and feed product you buy will have the exact details of when to apply the formula for best results so always read the label.

How Does Weed And Feed Work?

Weed and feed products work by either preventing the plant’s protein production by blocking photosynthesis, or by inflicting root damage that leads to the weed dying. Simultaneously the fertilizer element of the treatment fuels healthy grass blade growth, leading to a more dense lawn. It is this dense and thick lawn that then helps prevent weed germination or growth by crowding out the competing weeds.

The timing of the application determines the effectiveness of weed and feed. Due to incorrect timing, poor or inconsistent results, leave many people thinking the product they have used does work or was too harsh on their lawn.

Applying Too Early

If applied too early in the season, your lawn may get more fertilizer than it needs leading to fertilizer scorch. Basically, your lawn will receive more fertilizer than it can process. Most types of grass need higher nutrients when actively growing mid-spring onwards. This is why most weed and feed formulas are extended-release and should be applied around April time.

Applying Too Late

Applying weed and feed in September reduces the overall effectiveness of the treatment. September is a great time to treat and kill weeds, but it’s not the best time to treat grass as the nutrient is used to fuel top foliage growth, leading to week a weaker root network over winter. After August you would be better taking a different approach by applying a stand-alone Weedkiller for lawns in September and a Lawn Fertilizer in October.

So as you can see, it is all about getting the timing right. Again, always follow the product’s application instructions for ideal results.

How Long Does Weed And Feed Take To Work?

Assuming you’ve chosen the right product based on your grass and weed type, (don’t worry, our reviewed products specify all this!) it usually takes between 4 days and 1 month to notice results if the product is applied during the growing season.

You will notice dandelion, moss, clover, and other weed patches will black or brown and die off.

How Long Does Weed and Feed Last

Every product will have its own manufacture’s recommendations. But in general weed and feed products are applied either, once, twice, or periodically throughout the growing season, for example, every two months or so.

My personal preference is to use a product like Scotts Turf Builder that is designed for twice a year application between April and September when the weeds are actively growing.

Common Weed And Feed Questions Deboned

What is weed and feed? Weed and feed is an interchangeable, universal name given to a wide variety of lawn chemicals that have the purpose of strengthening the lawn by killing weeds. It generally improves your lawn’s ability to absorb water and food and adds necessary nutrients which promote healthy growth.

A healthy lawn, in turn, discourages weed propagation, enabling the use of a reduced amount of the product over time. There are many types of weed and feed that we will drill down on for further learnings.

What is the “weed” in my weed and feed? The weed component is comprised of herbicides (typically Dicamba, 2, 4-D and/or MCPP). These chemicals are designed to squelch dandelions, dollarweed and the most common green leafy weeds.

What makes up the “feed” in my weed and feed? The “feed” is a fertilizer. Typically, it is a combo of nitrogen, phosphorous and/or potassium. The blends vary, but all are designed to help your lawn flourish.

How does weed and feed work? Granules are applied to and absorbed by the leaves of the weed but doesn’t kill regular grass (unless too much is applied). In addition to the granular form, liquid forms are available that can be applied with a sprayer.

What is pre-emergent weed and feed? Pre-emergent weed and feed, as the name implies, targets weeds before they appear. Pre-emergent weed and feed does not control existing weeds. Annual applications over the target area for best results. Water in your pre-emergent weed and feed to activate the herbicide and create a barrier against weeds before they grow.

What is post-emergent weed and feed? Post-emergent weed and feed is the most common form for ridding weeds from lawns. When you already have weeds, the post-emergent weed and feed varietal is in order. Using a mixture of chemicals, they kill the weed and keep it from growing back.

How do seasons impact my weed and feed strategy? To be effective with your weed and feed strategy, you need to get the timing right. As a rule of thumb, time the application of weed and feed with the fertilization of the lawn during the last week of March or early April.

Keeping weeds out of your lawn can often be a chronic struggle that requires a strategy that is comprehensive and continuous. Understanding when to use pre-emergent weed and feed versus post-emergent as well as getting the timing right can be the winning combination to help you reach the finish line.

How to apply weed and feed

Fall’s arrival brings changes in day length, temperature and precipitation, along with important changes in your lawn. Some lawn grasses and weeds begin to slow down and prepare for winter dormancy, but others kick into high gear. Feeding your fall lawn provides helpful nutrients to fight weeds and strengthen lawn grasses for the winter ahead. However, what and when to feed and how to manage weeds depends on your climate and the type of grass you grow.

Feeding Cool-Season Lawn Grasses

How to apply weed and feed

Cool-season grasses, such as Kentucky bluegrass, perennial ryegrass and fescues, flourish in northern regions with warm summers and cold winters. Cool, moderate, early fall temperatures send these grasses into their most active growth season, which is the ideal time for fertilizing and strengthening.

Start fertilizing cool-season grasses about six weeks before the average first frost in your area. Fresh out of summer dormancy, these grasses benefit from added fall nutrition, which spurs new shoot, stem and root growth, and helps increase their food reserves. 1 September and October are prime cool-season fertilizing times for much of the United States.

A high-nitrogen lawn fertilizer with added potassium, such as Pennington UltraGreen Lawn Fertilizer 30-0-4, stimulates dense, healthy growth and supports winter and summer hardiness. The added boost of natural organisms from Pennington’s Myco Advantage technology increases the surface area of grass roots, improving your lawn’s ability to absorb water and nutrients, and enter winter prepared.

With broadleaf lawn weeds still actively growing in early fall, a weed & feed product such as Pennington UltraGreen Weed & Feed 30-0-4 fertilizes established cool-season lawns and kills a broad spectrum of common weeds through the help of three separate weed fighters. Follow label instructions closely to ensure you don’t exceed annual limits for broadcast applications.

Fertilizing Warm-Season Grasses

How to apply weed and feedWarm-season grasses, such as Bermudagrass, bahiagrass, centipede grass and zoysia grass, thrive in southern regions and peak in growth during warm summer months. As fall approaches, their growth slows and dormancy sets in with the season’s first killing frost.

Feed warm-season grasses their last feeding of the season six to eight weeks before the average fall frost date in your region. They’re still actively growing, but they’ll soon need to harden off and prepare for winter. Bermuda grass has higher nitrogen needs than some other warm-season grasses, so it can be fertilized up to four to five weeks before frost. 1 But don’t feed warm-season lawns any later. Fertilizing too late in the growing cycle can stimulate late-season growth that delays dormancy and makes lawns more susceptible to winter injury.

Warm-season grasses often go dormant and turn brown during winter, leading many southern lawn owners to overseed lawns with a cool-season grass that provides temporary green color through the winter months. Overseeding should take place at least 45 days before your average first fall frost, so new seeds can establish before winter. 2 Fertilize newly overseeded fall lawns with a starter fertilizer such as Pennington UltraGreen Starter Fertilizer 22-23-4, which supports robust root growth and greening of the cool-season grass. Avoid using weed & feed products on newly overseeded lawns, as they may prevent germination of the new grass seed. Consult your local Cooperative Extension Service for current information on limits for lawn fertilizers in your region.

Managing Fall Lawn Weeds

Like lawn grasses, common lawn weeds are either warm- or cool-season plants that follow the same seasonal growth peaks that lawn grasses do. Annual weeds, such as warm-season crabgrass, complete their life cycle in one year – but leave plenty of seeds behind for years to come. Perennial weeds, including cool-season plantains, live many years. Untreated, they come back from the roots year after year and spread extra seed, too.

Early fall is a perfect time to tackle tough turf weeds. Existing perennial weeds are still active and hard at work storing up food reserves, which leaves them very vulnerable to treatment. Weed killers get swept through the plant along with carbohydrates meant for energy stores in stems and roots, and few parts of the plant escape. 3 As warm-season weeds go dormant, movement through weeds slows or stops and resilience increases, making treatment more difficult.

In established fall lawns, weed & feed products help prevent cool-season weed seeds from germinating and emerging. In dormant southern lawns, emerged cool-season weeds stand out bright green against brown lawn grasses, which makes spot treatment easy. Effective post-emergent weed treatments, such as IMAGE All-in-One Killer, offers broad-spectrum fall control for difficult sedges, crabgrass and broadleaf weeds. IMAGE Kills Nutsedge, available in concentrate and ready-to-spray formulas, controls winter weeds in warm-season lawns, including Poa annua, also known as annual bluegrass, a troublesome annual weed common in Bermudagrass lawns.

Feeding your fall lawn and controlling its weeds helps leave grasses strong and healthy. With the help of the Pennington UltraGreen line of lawn fertilizers and IMAGE weed treatments, your lawn will be ready for the months ahead.

Never use any weed product on a lawn grass unless the grass is noted on the product’s label.

How to apply weed and feed

Before you plant grass seed, you should always prepare the area by removing any weeds that may be growing in the location. Even with careful preparation of the planting site, weeds can still develop among the newly planted grass seed. Weed killers, however, can harm grass seeds and seedlings if applied too early or improperly.

Application Timing

A general rule of thumb is to wait at least until you have mowed the new grass four times before using any standard postemergent broadleaf herbicide. A standard pre-emergent herbicide should not be applied until at least three to four months after seeding the area.

Herbicides and Seeding

Some pre-emergent herbicides can safely be used during seeding and usually come mixed with a seed starter. These products have the active ingredient Siduron – also known as Tupersan – that works by suppressing weed seeds while improving root development of the new grass. The fertilizer and pre-emergent herbicide mix is applied with a drop or rotary spreader using a rate of 2 1/2 pounds per 1,000 square feet. The spreader setting and actual application depends on the brand of starter fertilizer plus weed control you use, and you should always follow the instructions found on the label.

Weed Control after Seeding

You can control weeds in newly planted grass seed and seedlings without the use of herbicides. Manually pulling the weeds by hand when they first appear keeps them from producing seeds and prevents the problematic plants from spreading, according to the University of California Statewide Integrated Pest Management Program website. They suggest keeping the newly planted grass weed free with proper mowing, irrigation and fertilization. Since newly planted turfgrass has short roots, keep the root zone moist by watering the soil lightly. However, avoid over saturating the soil. After the turfgrass has become established, promote deep and healthy root growth by watering infrequently but deeply.

Considerations and Precautions

Weed management should be completed before seeding the lawn with a non-selective herbicide seven to 14 days before you till the soil. A second application of the herbicide may be required to kill any weeds you missed during the first treatment. Wait another seven days until tilling the soil if a second application is used.

Remember that all herbicides are different and the exact time you must wait to apply weed killers to newly planted grass will vary from one product to another. Also, some herbicides cannot be applied to certain species of turfgrass. For best results, always refer to the herbicide bottle’s label.
