Choosing the right lawn feed and weed product can be overwhelming, especially with so many options available. There are over 100 types of weeds that can infest your lawn, including dandelions, clover, and plantain.
The type of lawn you have will determine the best product for you. For example, if you have a newly seeded lawn, you'll want to use a product that's specifically designed for new lawns, such as a starter fertilizer that contains phosphorus.
As for weeds, it's worth noting that some products can kill weeds, but also harm your lawn. This is why it's essential to choose a product that's safe for your lawn type.
Lawn Feed Safety
Applying the wrong amount of weed and feed can damage your lawn. It's easy to apply too much or too little, both of which are detrimental to your grass's health.
Weed and feed products often don't provide the same level of protection as pre-emergent herbicide, which helps block germinating weeds from emerging. This can leave your lawn vulnerable to weed growth.
The chemical 2,4-D found in most weed and feed products can be harmful to the environment, including birds and aquatic life. Chemical runoff from 2,4-D has been linked to cancers in salmon populations.
Here are some common issues with weed and feed application:
- Over/Under Application
- Run-off and Drift
- Continuous Usage
Safe for
You can apply weed and feed safely on a calm, dry day, after mowing your lawn 3-4 days prior.
It's essential to choose the right fertilizer to give your lawn the growth and color you're after, and to use a drop spreader or broadcast spreader for optimum coverage.
Make sure to remove any weed and feed product from sidewalks and driveways to prevent damage to the environment.
Children and pets should be kept off the grass until the weed and feed has been absorbed into the grass and residue has been washed away.
You should allow at least 24 hours for the grass to absorb the product before watering, and in some cases, you may need to leave longer.
Here's a quick rundown of the safe timing for lawn care after weed and feed application:
Remember to always refer to your product's directions for timings and application rates.
Pesticide Harmful to Your Lawn
Using weed and feed products can be detrimental to your lawn, and it's essential to understand why. The nitrogen-rich fertilizer in these products can cause grass blades to get stressed and even die if applied without considering the specific needs of your lawn.
The instructions on the package are often too general, leading to the risk of applying too much or too little weed and feed, both of which can damage your lawn. This is especially true if you have a lawn with unique conditions or requirements.
2,4-D, a common chemical found in weed and feed, targets broadleaf weeds like dandelions or clovers, but won't affect grassy weeds like crabgrass or annual bluegrass. This means that your lawn may still be vulnerable to these types of weeds even after using weed and feed.
Using weed and feed products can also have negative environmental impacts, such as chemical runoff that can harm local ecosystems. For example, birds may eat the granules that don't dissolve, and 2,4-D has been linked to cancers in salmon populations.
Here are some of the common drawbacks to using weed and feed:
- Over/Under Application – Too heavy-handed and you potentially kill the grass you’re trying to weed and feed. Too little, and you won’t get the results you are after.
- Run-off and Drift – Whenever weed killers or fertilizer get into water systems, they cause havoc with the environment.
- Continuous Usage – Repeated doses of chemicals can adversely damage your lawn, reducing the health of your soil.
Considerations When Using
Using weed and feed products can be a bit tricky, so it's essential to consider a few things before applying them to your lawn. Blindly applying nitrogen-rich fertilizer without considering factors like grass type, climate, and soil conditions can stress and even kill your grass blades.
You need to identify the common lawn weeds you want to kill off and choose the best product for your project. This will ensure you're targeting the right weeds and not harming your grass. It's also crucial to select the right fertilizer to give you the growth and color you're after.
If you have a healthy and thriving lawn, you may not want to give it more "food" in the spring, so it's best to use a post-emergent herbicide on its own. This will help prevent fertilizing in the spring, which can increase your lawn mowing duties.
Make sure to consider the type of grass you have and the season you're in. For example, it's best not to feed a warm-season turf like centipedegrass or Bahiagrass in the fall, as this can dramatically increase the chance of winterkill.
Here are some key considerations to keep in mind when using weed and feed products:
- Over/Under Application: Too heavy-handed and you potentially kill the grass you're trying to weed and feed, too little and you won't get the results you're after.
- Run-off and Drift: Weed killers or fertilizer getting into water systems can cause havoc with the environment, so be careful not to let it drift into nearby water sources.
- Continuous Usage: Repeated doses of chemicals can adversely damage your lawn, reducing the health of your soil.
It's also essential to follow the manufacturer's instructions and always refer to the product label for timings and application rates.
Product Types
There are different types of weed and feed products, each with its own unique characteristics. Some products contain slow-release formulas that provide a steady supply of nutrients over time.
These slow-release formulas promote long-term lawn health by releasing nutrients gradually, rather than all at once. This can be especially helpful for lawns that need a boost of nutrients without burning them out.
Here are some of the top weed and feed products you can buy right now, categorized by type:
Bioadvanced 24 Lbs. Granule for Northern Lawns

These fertilizers have already dissolved in water, which allows the grass to absorb the nutrients rapidly. This can be beneficial for lawns that need a quick boost of nutrients.
Drawbacks to Using
Using weed and feed products can be a gamble, and the drawbacks are more than just a minor inconvenience. Too heavy-handed and you potentially kill the grass you're trying to weed and feed.

The instructions on the package are often not tailored to the needs of your lawn, leading to applying too much or too little weed and feed, both of which damage your lawn. This can result in stressed or dying grass blades.
Run-off and drift are also major concerns. Whenever weed killers or fertilizer get into water systems, they cause havoc with the environment. For instance, if weed and feed drifts into your fish pond, it is likely to result in the death of your fish.
Continuous usage of weed and feed products can also have long-term effects on your lawn. Repeated doses of chemicals can adversely damage your lawn, reducing the health of your soil. This can lead to a decline in the overall health and appearance of your lawn.
Here are some of the most common drawbacks to using weed and feed products:
- Over/under application: Too heavy-handed and you potentially kill the grass you're trying to weed and feed.
- Run-off and drift: Whenever weed killers or fertilizer get into water systems, they cause havoc with the environment.
- Continuous usage: Repeated doses of chemicals can adversely damage your lawn, reducing the health of your soil.
Application and Usage
To apply weed and feed properly, you want to mow your lawn two to four days before use. This ensures the weeds are actively growing and gives them a couple of days to recover after mowing.
Always follow the manufacturer's guidelines for the recommended application rate, as over-applying fertilizer can scorch or "burn" the grass due to the salts in the product.
Use a broadcast spreader to apply the product uniformly across the lawn, making two passes to create a crosshatch pattern. Be extremely careful around the lawn's perimeter to avoid spreading the granules into flower beds, vegetable gardens, or ornamental shrubbery.
To avoid harming the environment, make sure to remove any weed and feed product from sidewalks and driveways, as it can be washed into drains and waterways.
Here's a step-by-step guide to applying weed and feed safely:
- Identify the common lawn weeds you want to kill off, and buy the best product for your project.
- Select the right fertilizer to give you the growth and color you’re after.
- Choose a calm, dry day to start your weed and feed program.
- Mow your lawn 3-4 days prior to when you wish to apply your weed killer element or weed and feed product.
- Water your turf lightly, just enough to dampen the leaves before beginning your weed and feed plan.
- For optimum coverage, use either a drop spreader or broadcast spreader to apply your weed and feed.
- Keep children and pets off the grass until weed and feed has been absorbed into the grass and residue has been washed away.
- Don’t be too quick to water your lawn following application of weed and feed products. Allow at least 24 hours for the grass to absorb the product and for it to start to take action.
Do Not Apply Fertilizers
Don't even think about applying additional fertilizers to your lawn unless you're absolutely sure it can handle it. This can lead to fertilizer burn, which requires a lot of extra work to fix.
Too much nitrogen or other chemicals in fertilizer can severely damage your lawn, especially if you're already using a weed and feed product. It's like adding fuel to a fire that's already burning.
The best way to determine if your lawn needs more fertilizer is to have a soil test done. This will help you understand the nutrient levels in your soil and what, if anything, needs to be added.
If you do decide to use additional fertilizers, make sure to follow the manufacturer's instructions and don't overdo it. Remember, a little fertilizer can go a long way.
As the article notes, it's especially difficult to apply both fertilizer and weed and feed at the same time without damaging your lawn. So, it's best to stick with one or the other, unless you've got a soil test to back it up.
Post Emergent
Post-emergent weed and feed is used to control weeds after they've sprouted and are growing. This type of product targets existing weeds that are actively growing.
Post-emergent herbicides work by killing off the above-ground parts of the weed they come in contact with, or they travel through the plant down to the roots and kill from the inside out. Make sure you know what type of post-emergent herbicide is in your weed and feed product, as they work differently.

Post-emergent products are most effective when weeds are actively growing, and they should be applied during the growing season when you can see the weeds. This helps maintain a healthy, weed-free lawn and allows your grass to flourish without competition.
Post-emergent herbicides work by attacking the foliage and roots of the weeds, ensuring they are eliminated from your lawn.

Best Time to Apply
The best time to apply weed and feed is in the spring after the weeds start popping up. This is usually when the product is most effective.
You should wait until your grass has mowed at least twice before applying weed and feed, especially if you have a new lawn or freshly planted grass seed.
In most cases, you can apply weed and feed again in the fall, but make sure to give your grass at least two months to recover from the first application.
Don't apply weed and feed more than twice a year, as this can lead to chemicals building up in the soil and potentially killing off all vegetation in your yard.
If you have a warm-season turf like centipedegrass or Bahiagrass, it's best to avoid fertilizing in the fall to prevent winterkill.

How to Use

To use weed and feed effectively, it's essential to choose the right product for your lawn and location. This may involve selecting a product that combines weed killing and fertilizing, or opting for a two-step process where you kill weeds first and then fertilize.
Mowing your lawn two to four days before applying weed and feed allows the weeds to be actively growing, giving you a better chance of success. Cut the grass at its normal recommended height to ensure the best results.
Follow the manufacturer's guidelines for the recommended application rate to avoid over-fertilizing and scorching your grass. Over-application can lead to fertilizer components running off into nearby waterways, threatening fish and plants.
Applying the product uniformly across the lawn is crucial. Use a broadcast spreader to make two passes across the yard, creating a crosshatch pattern for even coverage.
Be extremely careful around the lawn's perimeter to avoid spreading the granules into flower beds, vegetable gardens, or ornamental shrubbery. Drop spreaders are a better option for these areas since they don't throw the product like a broadcast spreader.
A different take: Cutting Grass after Weed and Feed

A calm, dry day is ideal for starting your weed and feed program. Water your turf lightly before beginning to dampen the leaves.
Here's a summary of the steps to follow:
- Choose the right product for your lawn and location
- Mow your lawn two to four days before application
- Follow the manufacturer's guidelines for application rate
- Apply the product uniformly using a broadcast spreader
- Be careful around the lawn's perimeter
- Water your turf lightly before application
Remember to wait two to four days after application before watering and avoid applying the product during a hot, dry spell.
When to Seed
Timing is everything when it comes to seeding your lawn. If you plan on seeding, do not apply a pre-emergent fertilizer, as it will prevent grass seed from growing.
Applying a pre-emergent fertilizer will also prevent weed seeds from germinating, so you'll need to wait until after seeding to tackle weeds.

What's in it?
Weed and feed products are a convenient way to fertilize and kill weeds on your lawn, but have you ever wondered what's actually in them? Well, let's break it down.
The "weed" portion of weed and feed is an herbicide that targets broadleaf weeds like dandelions, broadleaf plantain, chickweed, and dollar weed. It's usually made with 2,4-D, Dicamba, or MCPP.
The "feed" portion is a lawn fertilizer that contains varying amounts of nitrogen, phosphorous, and/or potassium. This helps to green up the grass and encourage a healthy lawn.
Some weed and feed products contain slow-release formulas, which provide a steady supply of nutrients over time, promoting long-term lawn health.
For more insights, see: Broadleaf Weeds
Other products may contain synthetic or organic materials, which release nutrients as they decompose.
Here's a breakdown of the typical components of weed and feed products:
Remember, always check the product label for specific information on ingredients and application instructions.
Application Tips and Tools
To apply weed and feed effectively, mow your lawn 2-4 days before application to ensure weeds are actively growing. This timing allows the grass to recover from mowing before being treated.
It's essential to follow the manufacturer's guidelines for the recommended application rate to avoid over-applying fertilizer, which can scorch the grass. Over-application can lead to fertilizer components running off into nearby waterways, threatening fish and plants.
To achieve uniform coverage, use a broadcast spreader and make two passes across the yard at half-application strength. This creates a crosshatch pattern that ensures even distribution of the product.
Be extremely careful around the lawn's perimeter to avoid spreading granules into flower beds, vegetable gardens, or ornamental shrubbery. Weed and feed is a broadleaf herbicide that can kill these plants.
To avoid spreading product into unwanted areas, consider using a drop spreader, which doesn't throw the product like a broadcast spreader.
Here's a quick rundown of the application process:
- Mow lawn 2-4 days before application
- Follow manufacturer's guidelines for application rate
- Use a broadcast spreader and make two passes at half-strength
- Be careful around perimeter areas
- Wait 2-4 days after application before watering
- Apply no more than twice a year

Pre Emergent
Pre-emergent weed and feed products control common weeds before they grow. These products are applied in early spring and keep weed seedlings from making their way out of the soil.
Pre-emergent herbicides interrupt cellular division, stopping the shoot from forming or the radicle from developing further. This prevents the sprout from pushing through the soil surface.
Applying pre-emergent products in early spring is crucial, as this is when weed seeds typically germinate.
Pros and Cons
Fertilizers that contain weed killers, also known as weed and feed products, can be convenient to use. However, they have some downsides.
Weed and feed products can save you time and effort by killing weeds and fertilizing your lawn in one application. They can also be less expensive than buying separate products.
But there are some cons to using weed and feed products. For example, they can burn your lawn if not applied correctly, which can be a costly mistake.
Some weed and feed products can also contain chemicals that can harm beneficial insects and microorganisms in your soil. This can disrupt the natural balance of your lawn's ecosystem.
Weed and feed products can be less effective than separate products in the long run, as weeds can develop resistance to the herbicides they contain. This means you may need to use more product or switch to a different type of herbicide.

Right Fertilizer for Your Yard
You can't just grab any fertilizer and expect it to work for your yard.
First, you need to learn about the different types of fertilizers and when to fertilize your yard. This will help you choose the right product for your specific needs.
Fertilizers can be applied at different times of the year, such as early spring, but it's essential to follow the recommended timing to avoid damaging your lawn.
Avoid applying additional fertilizers, especially if you're already using a weed and feed product, as this can cause fertilizer burn and require extra time-consuming lawn care remedies.
A soil test can help you determine if your lawn needs more fertilizer and what nutrients it requires. This is especially important if you're unsure about the nutrient levels in your soil.
