Scotts 4 Step Lawn Care – Step 2: Turf Builder Weed & Feed
Turf Builder Weed & Feed kills weeds that already exist in your lawn and feeds the lawn for up to 2 months. A new and improved formula means that you’ll get up to 2X more powerful dandelion and clover control!
How to use?
1) Check the Weather: If rain is in the forecast in the next 24 hours, apply another day. Rain can wash the particles off of weed leaves before it has a chance to work properly.
2) Fill and Set Spreader: Applying Scotts® Turf Builder® Weed & Feed requires a lawn spreader. If you need a new spreader, visit your local Valu today! Click here or reference the back of the product for spreader settings and full instructions.
3) Apply to Wet Lawn: Make sure the grass is wet from dew or sprinkling before applying. This helps particles adhere to weed leaves to produce best results. For even application walk at a steady pace slightly overlapping each pass. After applying this product you don’t water your lawn for at least 24 hours. Just like rain, watering your lawn after applying Weed & Feed washes the weed control particles off of weed leaves before they can fully work.
4) Clean-Up: Sweep product from hard surfaces onto the lawn to keep valuable feeding nutrients on the grass and out of storm drains.
When to apply?
Apply when weeds are most active, usually April-September. It’ll be effective as long as weeds are actively growing and daytime temperatures are between 60°F and 90°F.
If you have recently applied another fertilizer (e.g. Scotts® Turf Builder® Lawn Food or Scotts® Turf Builder® Halts® Crabgrass Preventer with Lawn Food) wait at least 30 days to apply Scotts® Turf Builder® Weed & Feed.
Apply up to twice a year, but wait at least 30 days between applications.
What exactly does it control?
Short answer: pretty much everything. Weed & Feed kills dandelions, clover, and other major lawn weeds.
Long answer: Aster, Bindweed, Bittercress, Black Medic, Buckhorn, Bull Thistle, Burclover, Buttonweed, Canada Thistle, Carpetweed, Catsear (Coast Dandelion), Chickweed, Chicory, Cinquefoil, Clover (Hop), Clover (Red), Clover (White), Cudweed, Curly Dock, Dandelion, Dichondra, Dollarweed, English Daisy, Evening primrose, Filaree, Fleabane, Ground Ivy, Hawkweed, Healall, Henbit, Horseweed, Knotweed, Lambsquarters, Lespedeza (Seedling), Lippia (Matchweed), Mallow, Moneywort, Morning Glory, Pepperweed, Pigweed, Plantain, Pursiane, Pusley, Ragweed, Red Sorrel (Sheep Sorrel), Scarlet Pimpernel, Shepherd’s-purse, Smartweed, Sowthistle, Spurweed, Vetch, Wild Carrot, Yarrow, Yellow rocket
Kids and Pets?
Keep people and pets off lawn during application. Do not allow people or pets to enter treated areas until dusts have settled. Particles should stick to weed leaves for at least 24 hours after application, so it is best to limit activity from kids and pets for 24 hours after application.

Before You Buy
Maintaining a healthy lawn includes mowing, weeding, watering, and fertilizing. However, fertilizing isn’t always necessary. Over-fertilizing your lawn will make the grass grow more vigorously, causing you to have to mow more frequently or lead to run-off which ends up in your local watershed.
Excessive fertilizing can result in lawn burn, which is when the nitrogen and salt levels in the soil are too high and cause yellow to brown strips or patches of dead grass. A lawn, as with any type of plant, only needs fertilizing if the soil lacks the vital nutrients to help it grow. In situations like these, fertilizing your soil is essential.
Types of Weed and Feed
Weed and feed comes in two forms: liquid and granular. Although the liquid forms are easier to apply and provide faster results, it’s more economical to use the granular form. Spray or liquid weed and feed are designed for small yards. Granular weed and feed covers more area, often 5,000 square feet or more, and are available in 18-lb bags and larger. Granular versions offer a better value for your money, but you do need to water your lawn after application for it to penetrate the grass.
Some weed and feed feature slow-release formulas so you don’t have to fertilize as often. However, to achieve good results plan on treating your lawn at least once every eight weeks from the start of spring.
What to Consider When Choosing the Best Weed and Feed
Type of Turf Grass
The best weed and feed product for your lawn depends on the type of grass you have. Grass species have different nutrient requirements, so not all of them are safe for every species of grass. Using the wrong product can damage your grass. In general, grass species are divided into two categories: warm season and cool season. The seasons do not refer to the time of year, but the climate and average soil temperature range.
- Warm-season turfgrasses grow best with average soil temperatures between 80 and 95 degrees Fahrenheit. Warm-season grasses thrive in warmer climates found in the Southeastern and Southwestern United States and include Bahia grass, Bermuda grass, carpet grass, Saint Augustine grass, and zoysia grass (Japanese lawn grass).
- Cool-season turfgrasses grow best with average soil temperatures between 60 and 75 Fahrenheit. Cool-season grasses thrive in the cooler climates of the Midwest and Northern regions of the United States. Some cool-season grasses are Kentucky bluegrass, perennial ryegrass, and tall and hard fescue.
Selecting a fertilizer and weed killer that’s compatible with your grass species will give you far better results.
To grow a lush lawn, your soil needs to have essential nutrients. Fertilizers temporarily add nutrients to the soil. Fertilizers denote their nutrient ratios as NPK. This denotation represents the percentage of nitrogen (N), phosphorus (P), and potassium (K) in the product. This is how the nutrients help grass:
- Nitrogen helps the grass to grow properly and develop a green color.
- Phosphorus helps to develop strong root systems.
- Potassium protects plants from disease, drought, and cold.
There are at least 11 states that ban phosphorus fertilizer use or sale. Luckily, many lawn weed and feed products available have adapted to this and have removed phosphorus from the product. Don’t worry—the weed and feed will still green up and thicken the grass without the additional phosphorus.
Fertilizers can also contain secondary elements and micronutrients needed for healthy growth such as sulfur, calcium, magnesium, boron, iron, molybdenum, zinc, copper, chloride, nickel, and manganese. To find out exactly what nutrients your lawn needs can be determined by conducting a soil test. You can either purchase a test to use at home or take a soil sample to your local cooperative extension testing office.
Many fertilizers also have built-in herbicides or weed preventatives. Some products are better at killing certain types of common weeds and pests than others. In general, most weed and feed target common types of broadleaf weeds including plantain, chickweed, creeping charlie, dandelions, and clover.
Weed preventers, or pre-emergent weed killers, block weed seeds that are already in the soil, like crabgrass, poa annua, chickweed, and henbit, from germinating. Identify the type of weeds that are infesting your lawn and then make sure you choose a product that’s made to take care of it.
Our Top Picks
The following list takes into account the above considerations to narrow the field to some of the most effective weed and feeds on the market. This list includes both liquid and granular weed treatments for improving your lawn.
How Long Does Scotts Weed and Feed Take to Work?
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 24-48 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.
