Scotts Turf Builder Weed & Feed5
Best for: Lawn owners who want to feed grass while targeting common weeds such as clover and dandelion. This combination product is described as helping thicken grass, which can crowd out future weeds.
Apply it to a wet lawn when weeds are actively growing and daytime temperatures are consistently between 60°F and 90°F. The label information says not to apply more than twice per year.
Limitation: Do not use this product on St. Augustinegrass, including Floratam, Dichondra, Lippia, Carpetgrass, or Bentgrass. Check your grass type before choosing it.
Scotts Turf Builder Triple Action1
Best for: Buyers looking for one product that feeds grass, controls listed lawn weeds, and prevents crabgrass. Its three-in-one formula also targets weeds including dandelion, clover, dollarweed, ground ivy, chickweed, plantain, and henbit.
The listed grass types include Bahiagrass, Centipedegrass, Kentucky Bluegrass, Perennial Ryegrass, Bermudagrass, Tall Fescue, Fine Fescue, and Zoysiagrass. Choose this product if crabgrass prevention is a priority alongside routine weed control and feeding.
Limitation: It is not listed for every grass type. Confirm that your lawn species is included before application.
Scotts Liquid Turf Builder With Plus 2
Best for: People who prefer applying fertilizer and weed control with a hose-end sprayer. The product provides a quick nitrogen boost and targets listed broadleaf weeds, including buckhorn, chickweed, ground ivy, henbit, knotweed, oxalis, plantain, and spurge.
To apply, attach the hose-end applicator to a garden hose and spray the lawn. The supplied product information recommends applying when weeds are actively growing for best results. It may suit buyers who want a liquid application rather than a granular spreader product.
Limitation: The feature information describes broadleaf weed control, not crabgrass prevention. Choose another option if crabgrass prevention is a key requirement.
Scotts WinterGuard Fall Weed & Feed3
Best for: Lawn owners planning a fall feeding and weed-control application. This product is designed to control listed weeds and feed grass in fall, with the aim of preparing the lawn for the following spring. It targets over 50 listed weeds, including clover, dandelion, plantain, and purslane.
Apply it to a moist lawn while weeds are actively growing and temperatures are consistently between 60°F and 90°F. The timing and temperature guidance make it a seasonal choice rather than a general-purpose option for any time of year.
Limitation: Its stated application window is fall. If you need a spring or summer treatment, compare products intended for those seasons.
BioAdvanced 5-in-1 Weed And Feed
Best for: Buyers seeking wide-ranging weed control and prevention in a granular product. The formula targets over 200 listed weeds, including dandelions, clovers, and black medic. Its features also describe control of large crabgrass and a soil barrier intended to prevent listed weeds from emerging for up to six months.
The product information recommends applying it to actively growing turf in spring or early summer. It may be a better fit than a basic weed-and-feed option when preventing new listed weeds is part of the goal.
Limitation: The stated prevention period applies to listed weeds, not necessarily every weed. Read the product directions to confirm application timing and target weeds.
Buying Guide: How To Choose Grass Fertilizer And Weed Killer
Which weeds do you need to control?
Identify the weeds in your lawn before selecting a product. Some options focus on broadleaf weeds such as clover and dandelion, while Triple Action1 also includes crabgrass prevention. BioAdvanced describes control of a wider list and a barrier against certain future weeds. Check the product label for the specific weeds you want to target.
Does the product match your grass type?
Grass type can determine whether a lawn treatment is suitable. Review the label before application, especially for Weed & Feed5, which specifically excludes several grass types. Triple Action1 lists the turf types for which it is intended. When your grass type is uncertain, identify it before applying a combination product.
When should you apply it?
Timing varies by product. The listed fall product calls for fall application, while Weed & Feed5 specifies a wet lawn, actively growing weeds, and consistent daytime temperatures between 60°F and 90°F. Follow the selected product’s directions rather than assuming all weed-and-feed formulas use the same conditions.
Would liquid or granular application work better for you?
Liquid products with hose-end applicators can simplify spraying, while granular products are spread over the lawn. Choose based on the application method you can use accurately and the product’s instructions. Do not select a formula based on format alone: target weeds, grass compatibility, and seasonal timing matter too.

Which product includes crabgrass prevention?
Scotts Turf Builder Triple Action1 is described as feeding grass, controlling listed weeds, and preventing crabgrass. BioAdvanced 5-in-1 also describes crabgrass control and a barrier against listed weeds.

No. The supplied product information says not to use Scotts Turf Builder Weed & Feed5 on St. Augustinegrass, including Floratam.
