Scotts Turf Builder Weed and Feed5 — 4000 Sq Ft
Features include weed killing plus lawn feeding to thicken the turf and crowd out future weeds. It targets clover and dandelion while boosting lawn density. Best for homeowners with medium-sized lawns that frequently contend with broadleaf weeds. Limitations include restrictions on certain grasses like St. Augustinegrass varieties. Consider this option if your lawn needs a single treatment that both controls weeds and nourishes root growth.
Best for: Homeowners with up to 4,000 square feet who want combined weed control and fertilizer in one application.
Scotts Liquid Turf Builder With Plus 2 Weed Control
Features include a quick nitrogen boost and ready-to-spray convenience via a hose-end applicator. It targets broadleaf weeds such as buckhorn, chickweed, ground ivy, oxalis, and more. Best for homeowners who want fast results with a simple spray-on regimen and a manageable 2,000 sq ft per bottle scale. Limitation to consider: coverage per bottle can be lower than granular options, so plan multiple applications for larger lawns.
Best for: Lawns needing rapid weed suppression combined with a quick nutrient boost, particularly in smaller to mid-sized yards.
Scotts Turf Builder Liquid Lawn Food Plus Weed Control
This 2-in-1 formula combines weed control with lawn feeding to build a thicker, greener lawn that crowds out future weeds. The 32 fl oz bottle connects to a hose for easy application, boasting up to 2,000 sq ft of weed control. It also emphasizes less plastic waste with a reusable applicator system. Choose this if you prioritize ease of use and a quicker application process for smaller to mid-sized lawns.
Best for: Gardeners seeking a hose-end spray option that delivers weed control and feeding in one pass for up to about 2,000 square feet.
BioAdvanced 5-in-1 Weed and Feed Granules
BioAdvanced combines five actions: weed kill, lawn food, disease suppression, insect suppression, and a barrier to prevent new weeds for up to six months. It targets more than 200 listed weed types, including dandelions and clovers. This granular option is suitable for larger landscapes where a longer protection window is desirable. A potential limitation is the need to apply during active growth periods and follow label specifics for lawn type compatibility.
Best for: Lawns facing persistent weed pressure across multiple weed species, seeking a long-lasting barrier and robust feeding in one product.
Scotts Turf Builder Weed and Feed5 — 12,000 Sq Ft
This is a high-capacity option for large lawns, delivering weed control and lawn nutrition over an expansive area. It targets broadleaf weeds such as dandelions and clover while promoting thicker turf to crowd out future invaders. Best for households with larger properties and a need to limit application frequency. Limitation: more product per bag means heavier handling and storage considerations; ensure your lawn size aligns with the 12,000 sq ft coverage claim.
Best for: Large yards requiring powerful weed control and fertilizer in one product, with fewer annual applications.
Buying Guide: How to Choose The Right Weed Killer Plus Fertilizer
What is the main goal for your lawn? If you want quick green-up, consider products that emphasize fast nitrogen delivery along with weed kill. If weed pressure is high, a 5-in-1 or multi-year barrier may be more effective. Consider the following questions to tailor your choice:
How large is your lawn and how often do you want to fertilize?
- Small to medium lawns (up to 4,000 sq ft): options like Scotts Turf Builder Weed and Feed5 (4000 sq ft) or Triple Action1 may fit well.
- Large lawns (over 4,000 sq ft): consider the 12,000 sq ft weed and feed option for fewer applications.
What weed types are most problematic?
- Broadleaf weeds (dandelions, clover): products labeled specifically for broadleaf control are advantageous.
- Crabgrass: choose formulations that include crabgrass preventer where relevant.
Do you prefer granular granules or liquid hose-end formulas?
- Granules: longer-lasting protection, often suitable for larger areas, but require careful application to avoid missed spots.
- Liquids: quick results, easy to apply via hose-end sprayer, convenient for smaller yards or rapid treatment.
What grass type do you have and are there any turf restrictions?
- Some products list restrictions for grasses like St. Augustinegrass or Bentgrass. Verify compatibility with your lawn type before purchase.
Safety and timing considerations
- Apply when weeds are actively growing and temperatures are favorable (often 60–90°F). Avoid applying more than the recommended frequency per year to prevent turf stress.
Frequently Asked Questions
- Can I use weed killer plus fertilizer on all lawn types? Not all products are compatible with every grass type. Check the label for turf restrictions and adjust accordingly.
- How soon will I see results after applying? Some liquid formulas show quick green-up and weed control within days, while granular products may take longer to establish a resistant barrier.
- Is it better to treat the lawn in spring or fall? For broadleaf weeds and crabgrass prevention, spring or early summer applications align with active growth and weed emergence; follow the product label for seasonality.
- Do weed killers harm beneficial insects or soil health? Most products target actively growing weeds and provide lawn nutrition when used as directed. Avoid overspread and follow label directions to minimize impacts on non-target plants.
- Should I water after applying? Watering requirements vary by product. Some need a light watering to activate the product, while others specify no immediate watering. Always follow the label instructions.
- How often can I apply weed-and-feed products per year? Many labels limit applications to 1–2 times per year to prevent turf stress. Adhere to the given maximums on the product label.
