Best Fertilizer and Crabgrass Killer Products for Lawns
The best fertilizer and crabgrass killer depends on whether you want to prevent crabgrass, treat weeds already growing, or do both while feeding your lawn. Scotts Turf Builder Triple Action combines fertilizer, lawn weed control, and crabgrass prevention; Scotts Halts focuses on prevention; and Sunday offers a liquid weed-and-feed kit. The options below also include granular products for larger lawns and different coverage needs.
| Product | Best For | Coverage | Format |
|---|---|---|---|
| Scotts Turf Builder Triple Action | Combined lawn care | 4,000 sq. ft. | Granules |
| Scotts Halts | Crabgrass prevention | 5,000 sq. ft. | Granules |
| BioAdvanced 5 In 1 | Weed control and feeding | 10,000 sq. ft. | Granules |
| Andersons Crabgrass Preventer | Prevention with fertilizer | 6,000 sq. ft. | Granules |
| Sunday Liquid Weed & Feed | Liquid application | 5,000 sq. ft. | Two-part kit |
Scotts Turf Builder Triple Action
Best for: Lawn owners who want one granular product that combines lawn weed control, crabgrass prevention, and fertilizer. It covers up to 4,000 square feet, making it a practical option for a smaller or midsize treatment area.
The product name identifies three functions: weed control, crabgrass prevention, and lawn fertilization. Choose this if you want those tasks combined rather than buying separate products. Check the label to confirm the weeds and grass types listed for your lawn.
Limitation: Its stated coverage is lower than the 5,000- to 10,000-square-foot options here. As a crabgrass preventer, it is intended for prevention, not as a substitute for a product labeled to treat established crabgrass.
Scotts Halts Crabgrass Preventer
Best for: Buyers focused on preventing crabgrass and other listed grassy weeds. This 10.06-pound product treats up to 5,000 square feet and is described as a pre-emergent weed control for lawns.
Scotts Halts is a focused choice when preventing weeds is the priority and a combined weed-killer-and-fertilizer product is not needed. The product listing also names chickweed among the weeds it prevents. Compare its coverage with the area you need to treat before selecting a bag size.
Limitation: The listing emphasizes prevention rather than killing weeds that are already established. Choose another option if your main need is treatment of existing weeds, and verify that the label fits your lawn and application plan.
BioAdvanced 5 In 1 Weed And Feed
Best for: Homeowners treating a larger lawn who want a granular product described as controlling weeds and crabgrass while feeding, greening, and strengthening the lawn. The 24-pound bag treats up to 10,000 square feet, the largest stated coverage in this group.
Choose this if coverage is a priority and you want several lawn-care functions in one product. Its “5 In 1” positioning includes weed control and feeding, and the listing specifically mentions crabgrass. Read the product label for application directions and the weeds it targets.
Limitation: The listing does not provide a fertilizer analysis or a detailed list of every function in the product name. Confirm the label details before choosing it to meet a specific nutrient need.
The Andersons Crabgrass Preventer Plus Fertilizer
Best for: Buyers seeking crabgrass prevention combined with a clearly identified fertilizer analysis. The granular product uses Dimension and lists a 26-0-6 fertilizer analysis. One 17-pound bag covers up to 6,000 square feet.
This is a direct match for shoppers looking for a preventer-plus-fertilizer rather than a broad weed treatment. Choose it if the listed analysis and coverage suit your lawn-care plan. Its coverage falls between the smaller Scotts options and the larger BioAdvanced bag.
Limitation: The product name centers on crabgrass prevention, not treatment of established weeds. Check the label for the intended application conditions and compatibility with your lawn.
Sunday Liquid Weed & Feed
Best for: Buyers who prefer a liquid application and want fertilizer paired with an iron-based weed killer. The two-part kit covers up to 5,000 square feet and includes hose-end sprayers. Its listing names crabgrass, dandelion, clover, and chickweed.
Choose this if you value a hose-end application format over granular spreading. The fertilizer is listed as 22-0-2, and the kit separates it from the iron-based weed killer. That setup makes the product distinct from the granular all-in-one options.
Limitation: This is a two-part kit, so application involves handling both components rather than using one combined granular product. Follow the kit and product-label directions for each part.
Buying Guide: How To Choose Fertilizer And Crabgrass Killer
Do you need prevention or treatment?
Start by identifying whether crabgrass has already appeared. Products described as crabgrass preventers, including Scotts Halts and The Andersons, are prevention-focused. For weeds already present, compare products that explicitly describe weed killing, such as Scotts Triple Action, BioAdvanced 5 In 1, and Sunday Liquid Weed & Feed. Verify the target weeds on the label.
Which application format fits your lawn?
Granules are the format used by the Scotts, BioAdvanced, and Andersons products in this comparison. Sunday is a liquid kit with hose-end sprayers. Select a format you can apply according to its directions, and consider whether you prefer spreading granules or attaching a sprayer.
How much coverage do you need?
Measure the treatment area and compare it with the package coverage: 4,000 square feet for Scotts Triple Action, 5,000 for Scotts Halts and Sunday, 6,000 for The Andersons, and 10,000 for BioAdvanced. Coverage helps estimate how much product is needed, but it does not replace label directions.
Should fertilizer analysis affect your choice?
If fertilizer nutrients matter to your decision, The Andersons lists a 26-0-6 analysis and Sunday lists 22-0-2. BioAdvanced’s provided listing describes feeding, greening, and strengthening without naming an analysis. Compare the listed nutrient information with your lawn’s needs rather than assuming all weed-and-feed products have the same formula.
