A vibrant, green lawn is the dream of many homeowners. Achieving that verdant paradise often involves tackling pesky weeds and ensuring your grass gets the nutrients it needs. Weed and feed products offer a convenient solution by combining herbicide and fertilizer in a single application. However, applying weed and feed incorrectly can be ineffective, damage your lawn, or even harm the environment. This comprehensive guide will walk you through the best practices for applying weed and feed to achieve a healthy, weed-free lawn.
Understanding Weed and Feed
Before diving into the application process, it’s crucial to understand what weed and feed is and how it works. Weed and feed products typically contain a pre-emergent herbicide to prevent new weeds from sprouting and a post-emergent herbicide to kill existing weeds. They also include fertilizer to nourish your grass, promoting healthy growth and a thick, green appearance.
Different formulations cater to various grass types and weed species, so choosing the right product is essential. Look for weed and feed specifically designed for your grass type (e.g., fescue, bluegrass, Bermuda) and that targets the common weeds in your area (e.g., dandelions, crabgrass, clover).
Types of Weed and Feed Products
Weed and feed products come in two primary forms: granular and liquid. Each has its own advantages and disadvantages.
- Granular Weed and Feed: This is the most common type. It’s applied using a spreader and provides a slow-release of both herbicide and fertilizer. Granular formulas tend to be more forgiving in terms of application, but they require moisture to activate.
- Liquid Weed and Feed: This type is typically applied using a hose-end sprayer. It offers faster results, as the herbicide and fertilizer are immediately absorbed by the plants. However, liquid formulas require more precise application and can be more prone to runoff.
Choosing between granular and liquid depends on your personal preference, lawn size, and the specific needs of your grass. Granular is often preferred for larger lawns due to its ease of application, while liquid can be more effective for targeted weed control.
When to Apply Weed and Feed
Timing is crucial for successful weed and feed application. Applying at the wrong time of year can render the product ineffective or even damage your lawn. The ideal time to apply weed and feed depends on your grass type and the specific weeds you’re targeting.
Timing Considerations for Different Grass Types
- Cool-Season Grasses (e.g., Fescue, Bluegrass, Ryegrass): The best time to apply weed and feed to cool-season grasses is in the fall (September-November) and early spring (March-May). Fall application helps to strengthen the grass before winter and prevents winter annual weeds. Spring application controls spring weeds and promotes vigorous growth.
- Warm-Season Grasses (e.g., Bermuda, Zoysia, St. Augustine): The best time to apply weed and feed to warm-season grasses is in late spring or early summer (May-June), after the grass has fully greened up. Avoid applying weed and feed during the heat of summer, as this can stress the grass.
Always check the product label for specific timing recommendations for your grass type and the weeds you’re targeting.
Weather Conditions
Weather conditions also play a significant role in the effectiveness of weed and feed. Avoid applying weed and feed:
- Before heavy rain: Rain can wash away the product before it has a chance to be absorbed by the plants.
- During periods of drought: Dry conditions can stress the grass and make it more susceptible to damage from the herbicide.
- On windy days: Wind can cause the product to drift onto unintended areas, such as flowerbeds or vegetable gardens.
The ideal weather conditions for applying weed and feed are calm, dry, and with a forecast of no rain for at least 24 hours.
Preparing Your Lawn for Weed and Feed
Proper lawn preparation is essential for maximizing the effectiveness of weed and feed. Follow these steps to prepare your lawn:
Mowing
Mow your lawn 1-2 days before applying weed and feed. This will help to remove any tall grass blades that could prevent the product from reaching the soil and weeds.
Avoid mowing immediately after applying weed and feed, as this can remove the product from the weeds and reduce its effectiveness.
Watering
Water your lawn thoroughly 1-2 days before applying granular weed and feed. This will help to moisten the soil and allow the granules to adhere to the weeds.
If using liquid weed and feed, the lawn should be slightly moist but not saturated.
Identifying Weeds
Take the time to identify the specific weeds that are present in your lawn. This will help you to choose the right weed and feed product that is effective against those weeds.
Some weeds are more resistant to certain herbicides, so it’s important to choose a product that is specifically formulated to control the weeds in your lawn.
Applying Weed and Feed: Step-by-Step Guide
Now that you understand the basics of weed and feed and have prepared your lawn, it’s time to apply the product. Follow these step-by-step instructions for optimal results:
Step 1: Read the Label
This is the most important step. Carefully read and understand the product label before applying weed and feed. The label contains important information about the product, including the application rate, safety precautions, and any specific instructions for your grass type and weeds.
Step 2: Calibrate Your Spreader (for Granular Weed and Feed)
Calibrating your spreader ensures that you apply the correct amount of weed and feed. Over-application can damage your lawn, while under-application can be ineffective. Consult the product label for the recommended spreader setting for your spreader model.
- Fill the spreader with a known amount of weed and feed.
- Apply the product to a designated area.
- Measure the area covered and compare it to the amount of product used.
- Adjust the spreader setting as needed to achieve the recommended application rate.
Step 3: Apply the Weed and Feed
- For Granular Weed and Feed: Use a spreader to apply the product evenly across your lawn. Walk at a steady pace and overlap each pass slightly to ensure complete coverage.
- For Liquid Weed and Feed: Attach the hose-end sprayer to your garden hose and follow the instructions on the product label. Apply the product evenly across your lawn, being careful not to oversaturate any areas.
Avoid applying weed and feed to sidewalks, driveways, or other non-turf areas, as this can stain the surface and harm plants.
Step 4: Water (for Granular Weed and Feed)
After applying granular weed and feed, water your lawn lightly to activate the product. This will help the granules to dissolve and release the herbicide and fertilizer.
Do not water immediately after applying liquid weed and feed, as this can wash away the product.
Post-Application Care
After applying weed and feed, it’s important to follow these post-application care tips to ensure the best results:
Avoid Mowing
Avoid mowing your lawn for 2-3 days after applying weed and feed. This will allow the herbicide to be absorbed by the weeds and prevent it from being removed by the mower.
Watering
Avoid excessive watering for the first few days after applying weed and feed. This can wash away the product and reduce its effectiveness.
Monitor Your Lawn
Monitor your lawn for signs of weed control and grass growth. It may take several weeks to see the full effects of the weed and feed.
If you notice any signs of damage to your grass, such as yellowing or browning, stop using the product and consult with a lawn care professional.
Safety Precautions
Weed and feed products contain chemicals that can be harmful if not handled properly. Follow these safety precautions when applying weed and feed:

Make sure you’re using a product that is effective against the weeds in your lawn, applying it at the right time of year, and following the instructions on the product label.
- Grass is turning yellow or brown: This could be due to over-application of the product, applying it during hot weather, or applying it to stressed grass. Make sure you’re applying the product at the recommended rate, avoiding application during hot weather, and ensuring that your grass is healthy before applying weed and feed.
- Uneven coverage: This could be due to improper calibration of your spreader or uneven application of the product. Make sure you calibrate your spreader properly and apply the product evenly across your lawn.
If you’re experiencing problems with weed and feed, consult with a lawn care professional for assistance.
Alternatives to Weed and Feed
While weed and feed can be a convenient solution for controlling weeds and fertilizing your lawn, there are also alternative approaches that you may want to consider.
Separate Weed Control and Fertilization
Applying weed control and fertilizer separately allows for more precise control over the timing and application rates of each product. This can be particularly beneficial if you have specific weed problems or if your lawn has unique nutritional needs.
- Spot Treat Weeds: Instead of applying herbicide to your entire lawn, you can spot treat individual weeds with a targeted herbicide. This can reduce the amount of herbicide used and minimize the risk of damage to your grass.
- Apply Fertilizer Based on Soil Test: A soil test can determine the specific nutrient needs of your lawn. This allows you to apply fertilizer that is tailored to your lawn’s requirements, avoiding over-fertilization or under-fertilization.
Organic Weed Control and Fertilization
If you’re looking for a more environmentally friendly approach, you can consider using organic weed control and fertilization methods.
- Corn Gluten Meal: Corn gluten meal is a natural pre-emergent herbicide that can prevent weed seeds from germinating.
- Organic Fertilizers: Organic fertilizers, such as compost, manure, and bone meal, can provide essential nutrients to your grass without the use of synthetic chemicals.
Choosing the best approach for your lawn depends on your personal preferences, budget, and the specific needs of your lawn.
By following these guidelines, you can effectively apply weed and feed and achieve a lush, healthy, and weed-free lawn. Remember to always read and follow the product label and take necessary safety precautions. Happy gardening!
What exactly is weed and feed, and how does it work?
Weed and feed is a lawn care product designed to simultaneously fertilize your grass and control common lawn weeds. It typically contains a combination of fertilizer nutrients (nitrogen, phosphorus, and potassium) to promote healthy grass growth and one or more herbicides to target and kill existing weeds.
The fertilizer component works by providing essential nutrients that grass needs to thrive, resulting in a greener, denser lawn. The herbicide component, on the other hand, is absorbed by the weeds through their leaves or roots, disrupting their growth processes and eventually leading to their death. This dual-action approach simplifies lawn care by addressing both weed control and fertilization in a single application.
When is the best time to apply weed and feed?
The optimal time to apply weed and feed generally depends on the type of weeds you’re trying to control and the type of grass you have. For most common broadleaf weeds, like dandelions and clover, the best time is during the spring or fall when these weeds are actively growing. This allows the herbicide to be most effective as the weeds are actively absorbing nutrients.
However, avoid applying weed and feed during periods of extreme heat or drought, as this can stress your lawn and reduce the effectiveness of the product. Cool-season grasses like fescue and Kentucky bluegrass typically benefit from applications in the spring and fall, while warm-season grasses like Bermuda and St. Augustine grass are better treated in the late spring or early summer when they are actively growing. Always check the product label for specific recommendations based on your grass type and target weeds.
How do I prepare my lawn before applying weed and feed?
Before applying weed and feed, it’s essential to mow your lawn a few days prior to the application. This allows the weed and feed granules to reach the soil and weeds more easily, as the grass blades won’t be blocking them. Ensure the grass is dry when you mow to prevent clumping and uneven cuts.
Water your lawn thoroughly one to two days before application. This helps to hydrate the grass and weeds, allowing them to better absorb the fertilizer and herbicide. Avoid applying weed and feed to a stressed or drought-stricken lawn, as this can damage the grass. Properly preparing your lawn will maximize the effectiveness of the weed and feed treatment.
What type of spreader should I use for weed and feed?
The best type of spreader for applying weed and feed depends on the size of your lawn and your personal preference. Broadcast spreaders, also known as rotary spreaders, are generally recommended for larger lawns because they cover a wider area quickly and efficiently. They distribute the product in a broad pattern, making them ideal for lawns with even terrain.
Drop spreaders, on the other hand, are more precise and are better suited for smaller lawns or areas where you need to avoid applying weed and feed to certain plants or surfaces. They drop the product directly onto the ground between the wheels, preventing over-application and ensuring even coverage. Always calibrate your spreader according to the product label instructions to ensure the correct application rate and avoid damaging your lawn.
How do I apply weed and feed properly to avoid damaging my lawn?
Apply weed and feed according to the instructions on the product label. Over-application can burn your lawn, while under-application may not effectively control weeds. Calibrate your spreader correctly and walk at a consistent pace to ensure even distribution of the product. Avoid overlapping passes, as this can lead to excessive application in certain areas.
After applying weed and feed, avoid watering your lawn for at least 24 to 48 hours, unless the product label specifically instructs you to water immediately. This allows the herbicide to adhere to the weed leaves and the fertilizer to penetrate the soil. Also, keep pets and children off the treated area for the recommended period on the product label to prevent them from ingesting the product or coming into contact with the chemicals.
Are there any precautions I should take when using weed and feed?
Always read and follow the instructions on the product label carefully before using weed and feed. Wear appropriate protective gear, such as gloves and eye protection, to prevent skin and eye irritation. Avoid inhaling the dust from the product, and wash your hands thoroughly after application.
Store weed and feed in a safe place, out of reach of children and pets. Do not apply weed and feed near bodies of water or drainage areas, as the chemicals can contaminate water sources. If you accidentally spill the product, clean it up immediately and dispose of it properly according to local regulations.
How long will it take to see results after applying weed and feed?
The time it takes to see results from weed and feed can vary depending on several factors, including the type of weeds being targeted, the weather conditions, and the specific product used. You should typically notice the weeds beginning to wilt and die within one to three weeks of application.
The fertilizer component will start to green up your lawn within a week or two, providing the grass with the nutrients it needs to thrive. However, it’s important to be patient and allow the product sufficient time to work. Avoid mowing your lawn too soon after application, as this can remove the herbicide from the weed leaves and reduce its effectiveness.
