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.
Liquid Weed And Feed Vs Granular
Weed and feed products are generally available in two forms, liquid and granular. Both products are equally effective but have slightly different properties meaning they lend themselves to certain scenarios.
Liquid weed and feed or lawn fertilizers are applied using a spray mechanism, either by using a concentrate diluted with water and pumped through a backpack sprayer or through a convenient ready-to-use hand-held spray for smaller areas.
You can get several benefits from using a weed and feed spray:
- Targeting localized areas or patches of lawn
- Fast-acting and no need to water lawn pre or post-application
Granular weed and feed are generally preferred for larger areas of lawn and applied by spreading onto a pre-watered lawn.
- Easy to apply with a drop spreader, allowing for a consistent and good spread of the product
- They usually offer better value for money.
- They will soak into your garden over time and feature slow-release formulas so you won’t have to treat your lawn as often.
Organic Weed and Feed
If you are looking for a genuine organic weed and feed, first they can be difficult to find, and second, you cannot expect the same results as a synthetic or standard weed and feed. With organic products, the primary ingredient is corn gluten meal which is suitable for immediate contact after application. On our list, we feature Espoma Organic Weed Preventer and Westland Child And Pet-Friendly Organic Weed And Feed both organic therefore pet and family-friendly.
Family and Pet Safe Weed And Feed
For most of us with families, the safety of any product we distribute within our garden is a primary concern. Manufacturers understand this and thankfully there are a few products on the market that cater to this requirement.
Most weed and feed products will advise you to keep pets and children away from your lawn for 24 hours after the application. This will either be for their safety, as the product may contain ingredients that are hazardous if consumed. Or more often the weed and feed will stain surfaces if the pet or child picks up the material on their shoes or paws.
Always read the manufacturer’s guidance so you can use the product with confidence.
The 10 Best Weed And Feed Reviews
Over the years I have tested dozens of weed and feed products and have a good feel for the effectiveness of each product and when best to use them. My colleagues have also shared their experiences so we can bring a wealth of knowledge. Our judgment was based on overall performance and results, ease of use, and value for money. Hopefully, this list of the best weed and feed products will meet your garden’s needs. Let’s start our review with the best buy product from Scotts Turf Builder range:
Best Post Emergent Weed and Feed
Scotts is one of the best-known manufacturers of weed and feed and for good reason. It delivers exceptional performance in controlling dandelions and other tough-to-kill weeds, the Turf Builder is my best buy weed and feed product for you to check out. It’s highly effective and produced the kind of results that make me a loyal customer and regular user.
Apply it to a wet lawn and the Weedgrip technology allows the granules to stick to weed foliage making a direct and effective weed killer. Whilst the feeding formula thickens your lawn and makes it greener and lush. You can apply anytime between early spring and late fall, but I find outstanding results can be achieved if I apply early spring and then every 6 weeks for 4 applications until late fall, which produces outstanding results.
Suitable weed and feed for Bermuda grass, Fescues, Kentucky Bluegrass, Centipede, Ryegrass, and Zoysia or Bahiagrass.
Not only does the product kill dandelions, clover, and other common weeds, it also feeds common grasses, such as ryegrass and fescue. However, I would avoid using it on certain warm-season turfs, such as Carpet Grass and St. Augustine. This is a great product that’s available at most good garden stores or online at Amazon here.
How to use: this weed and feed product is a granular formula that can be applied with a drop, broadcast, or rotary spreader. For best results, apply evenly to a wet lawn and avoid watering or disturbing the lawn for 24 hours after application. Covers 5,000 sq ft. Apply up to 4 times per year between early spring and late fall.

Best Fall Weed and Feed
The premium brand, Scotts, has created a new and improved weed and feed formula that kills stubborn dandelion and clover. We found that crabgrass can also be eliminated if the product is applied in early spring. another reliable product that we have used many times with good results.
How to use: the best time to apply is in fall so that grass can be better prepared for the next growing season. To maximize the effectiveness of the product, grass must be wet during application.
Customer reviews: users were satisfied with the performance of this product and noticed their grass remained green even in the winter months. Scores 4.5/5 overall. Find it on Amazon.
The ever-popular brand, Miracle-Gro, has come up with yet another complete 4-in-1 weed and feed formula that helps your lawn absorb nutrients and water more effectively so that it can tolerate heat and drought.
The product kills moss and many other species of weeds, but it does take longer to take effect. Our test took 10 days to see noticeable results, but the results were good. For the best results use a drop spreader to evenly distribute the treatment across your lawn.

I’m a big fan of this slow-releasing compound from Greenview Fairway, which helps reduce your annual feeding and weeding costs. Greenview states their new and improved 65% nitrogen formula kills over 200 species of weeds and feeds the grass for up to 3 months. However, we have tested the product and found that it didn’t work so well work on St. Augustine grass, but was really effective on the other lawn tests. So perhaps pass this one by if you have St. Augustine grass, but use it with confidence on other grass types.
How to use: apply the granules in early spring when the lawn is wet using a drop or broadcast spreader. Wait 3 days before mowing the lawn.
Note: because of the slow-releasing properties of this weed and feed product, it is best used on established and healthy lawns. Using it on new grass may result in stunted growth.
Customer reviews: users noticed thicker and greener lawn right after the first application. The product helped turn grass green, but most users didn’t find it as beneficial for killing crabgrass.
- Excellent performing lawn fertilizer
- Requires infrequent application with noticeable results after 1 month
- Better-suited for established lawns
- May injure carpet grass and St. Augustine
- Not effective for killing crabgrass

How To Apply Weed And Feed To Lawns
Every weed and feed product has its own specific application instructions, which must be followed for safety and for optimum results. But to give you a general idea of how to apply weed and feed, here are some guidelines:
1. Mow and water the lawn two days before applying weed and feed. This helps ensure even distribution of the granules in the wet lawn.
2. Extreme temperatures will adversely affect your lawn’s tolerance so always choose a day when temperatures are higher than freezing but below 80 degrees Fahrenheit.
3. Don’t apply weed and feed immediately after heavy rain. Sure, you want the lawn to be moist but it shouldn’t be soggy!
4. Using a rotary or drop spreader, follow the exact instructions of the particular weed and feed product you’re using to apply the granules in your lawn. Cover the area evenly by walking back and forth across the lawn.
5. If you’re using a spray weed and feed, attach the liquid bottle to your garden hose and apply it in a precise pattern as per the instructions to ensure full coverage.
Most weed and feed products require more than one application to yield results. It is, therefore, important that you carefully follow the directions so as to avoid burning your grass.
When To Water After Applying Weed And Feed
It is generally recommended to water your lawn prior to applying weed and feed product to get the soil damp. Some products will require you to avoid watering your lawn for at least 24 hours after application. Whilst other products will need watering-in or a good period of rainfall before they become active and begin working. Check the manufacturer’s instructions to get the best results from your weed and feed product.
