Scotts Turf Builder Triple Action Lawn Fertilizer - 3-in-1 Weed

In this review of Scotts Turf Builder Triple Action, the bottom line is straightforward: this product is for homeowners who want a single-pass solution to feed their lawn while targeting common broadleaf weeds and preventing crabgrass for months. The biggest reason to buy is the three-in-one formulation that combines fertilization with weed control and crabgrass prevention, making seasonal lawn care simpler for yards up to 4,000 sq. ft. It is best used when applied with a broadcast spreader to a wet lawn and watered in after 24 hours.

Key Features

• Three-in-one formula: Kills listed broadleaf weeds, prevents crabgrass for up to 4 months, and feeds grass to promote a thicker, greener lawn.
• Broadleaf weed control: Controls common lawn weeds such as dandelion, clover, chickweed, plantain, and henbit to improve lawn appearance.
• Grassy weed prevention: Helps prevent grassy invaders like barnyardgrass, foxtail, and annual bluegrass when applied as directed.
• Multiple turf types: Safe for use on many common lawn grasses including Kentucky bluegrass, perennial ryegrass, tall fescue, bermudagrass, and zoysiagrass.
• Coverage: An 11.31 lb bag treats up to 4,000 sq. ft., which fits small to medium residential yards without frequent rebuys.

Who It's For

Homeowners with small to medium lawns who want to simplify early season care will like this product. It is aimed at people who prefer a combined approach: feeding the turf while tackling broadleaf weeds and keeping crabgrass from establishing for several months. The product works best when applied in early spring as dandelions begin to grow and when used with a Scotts spreader for even coverage.

Those who should look elsewhere include gardeners needing targeted control for a single stubborn weed species or users with extremely small, delicate lawns that require custom nutrient mixes. Also, if you need something that will kill existing crabgrass, this product is not the right choice, since it prevents but does not eliminate mature crabgrass.

Pros & Cons

Pros

• Combines feeding, broadleaf weed control, and crabgrass prevention in a single application for convenience.
• Formulation supports a richer, greener lawn color and overall turf health when used as directed.
• Works on a wide range of turf types, making it versatile for many regional lawns.

Cons

• Some users report mixed weed control results, so performance can vary with weed type and timing of application.
• Granule clumping has been mentioned by customers, which can affect spreader flow if not shaken or broken up.

Frequently Asked Questions

Can this product kill existing crabgrass?
No. It prevents crabgrass for up to 4 months but will not kill established crabgrass; use a targeted post-emergent for existing crabgrass.

When should I apply this product?
Apply in early spring when dandelions are actively growing and the lawn is wet from dew or watering so granules adhere to weed leaves.

How do I apply it for best results?
Use a Scotts spreader for even coverage, apply to a wet lawn, and water the lawn 24 hours after application to move nutrients into the soil.
