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

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 after 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?

How soon can you mow after spreading Scotts 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.
