Scotts Turf Builder Weed & Feed: Professional-Grade Lawn Care with Built-In Herbicide Control

Scotts Turf Builder Weed & Feed delivers what busy contractors need — fertilization and weed control in one pass. The 28-0-3 NPK formula feeds grass while the herbicide blend (2,4-D, Mecoprop-p, Dicamba) targets over 50 common lawn weeds. At 3.7 out of 5 stars across 3,400+ reviews, it’s a workhorse product that gets the job done when applied correctly.

Skip it if you’re dealing with St. Augustinegrass or Bentgrass — the herbicides will damage these grass types. This product shines on Kentucky Bluegrass and Perennial Ryegrass lawns where dandelions and clover have taken hold.

WeedGrip Technology and Active Ingredient Performance

The WeedGrip Technology grips the weeds you see and the ones you don’t. That’s marketing speak for selective herbicide action, but the chemistry backs it up. The active ingredients include 2,4-D at 1.21%, Mecoprop-p at 0.61%, and Dicamba at 0.053% — a proven combination that’s been controlling broadleaf weeds for decades.

Scotts claims up to 2X more powerful dandelion and clover control than previous formulas. In practice, users praise its effectiveness on dandelions and the quick greening of the lawn, though common complaints include inconsistent clover control and the risk of lawn burn if applied incorrectly.

It controls over 50 listed weeds, including clover, dandelion, and plantain. That’s the standard list you’d expect from any quality weed-and-feed. The real value is combining this control with nitrogen feeding in one application — saves time and trips across the lawn.

Application Specifications and Temperature Requirements

Getting the application right matters more than the product choice. Apply when weeds are actively growing and daytime temperatures are consistently between 60°F and 90°F. In Montana, that’s a narrow window — typically late May through early September, depending on elevation.

Spreader Type	Setting
Scotts Broadcast Rotary	3 3/4
Scotts Drop	7 1/4
Scotts Elite	4 1/4
Scotts Wizz	4 1/4

The application process demands attention to detail. Mow the lawn a day or two before application. Water the lawn lightly or apply on a dewy morning so granules stick to weed leaves. Make sure your grass is wet from dew or watering, as this helps particles adhere to weed leaves to produce the best results.

Do not water the lawn or expect rain for at least 24 hours after application. This 24-hour dry period is critical — watering too soon washes the herbicide off the weed leaves before it can work. Avoid mowing for 2 days after application.

Maximum 2 applications per year. That’s not a suggestion — it’s the label limit. More applications risk damaging your lawn and violating EPA regulations.

Grass Type Compatibility and Coverage

Know your grass type before spreading. This product works on the common cool-season grasses that dominate Montana lawns.

Avoid on these grass types: St. Augustinegrass (including Floratam), Dichondra, Lippia, Carpetgrass, Bentgrass

Do not use on flowers, shrubs, fruit or vegetable plants. Keep this product on the lawn — drift onto ornamentals will damage or kill them.

Coverage varies by package size. The 35.7 lb bag covers 12,000 sq ft. The smaller bag covers 4,000 sq ft. Calculate your lawn area before buying — over-application is the fastest way to burn a lawn.

The 28-0-3 NPK ratio provides quick nitrogen green-up without the phosphorus that many states now restrict. It builds thick, green turf from the roots up without burning the lawn — when applied at the correct rate.

Scotts backs this with their No-Quibble Guarantee: If for any reason you, the consumer, are not satisfied after using this product, you are entitled to get your money back. That’s confidence in the product, though most lawn damage comes from user error, not product failure.

FAQ

Q: Can I apply Scotts Turf Builder Weed & Feed to newly seeded lawns? A: No. Wait until new grass has been mowed at least three times before applying any weed-and-feed product. The herbicides will damage or kill young grass seedlings.

Q: What happens if it rains right after I apply the product? A: Rain within 24 hours reduces effectiveness. The herbicide needs time to absorb through the weed leaves. If rain washes it off too soon, you’ve essentially applied expensive fertilizer without the weed control benefit.

Q: How does Scotts Turf Builder compare to cheaper store brands? A: Vigoro is often lower in price but may have less uniform granules and more fillers. Sta-Green is a competitive value brand; Scotts is preferred for brand reliability and its No-Quibble Guarantee. You’re paying for consistent granule size and proven herbicide formulation.

Q: Why does the label say to apply when grass is wet? A: Wet grass helps the granules stick to weed leaves where the herbicide can work. Dry application means granules fall to the soil surface, reducing contact with target weeds. Morning dew provides ideal conditions.

Q: Is this product safe for use around kids and pets? A: Safe for kids and pets when used as directed. Keep people and pets off the lawn during application and until the product has been watered in or absorbed. Follow all label precautions.
