Scotts Turf Builder Weed & Feed (42.87 lb)
| Item Form | Granule |
|---|---|
| Coverage | 15000 square_feet |
| Active Ingredients | 24-D Mecoprop-p |
Scotts Turf Builder Weed & Feed is a granular lawn treatment that kills broadleaf weeds while feeding grass to encourage thicker turf. It is applied with a spreader when weeds are actively growing and temperatures are between 60°F and 90°F; the label recommends applying to a wet lawn so granules stick to weed leaves and waiting 24 hours before watering. The formula uses WeedGrip technology and lists active ingredients including 2,4-D and Mecoprop-p, and the 42.87 lb bag covers about 15,000 square feet. In practice this product is straightforward to broadcast across medium to large lawns and gives visible reduction of common weeds like dandelions and clover while supplying nutrients to help crowd out future weeds. Important limitations are application timing and grass restrictions: do not use on St. Augustinegrass, bentgrass, carpetgrass, dichondra, or lippia, and do not apply if rain is expected within 24 hours. Also keep people and pets off treated turf until dust settles. For homeowners who follow label directions, it is an efficient one-step option for late spring weed control and feeding.
Best for: Homeowners who want a single product to both reduce common broadleaf weeds and feed a cool- or warm-season lawn and who prefer a proven brand with clear label instructions and wide user adoption.
Less Ideal for: People with lawns made of excluded grass types or those needing immediate spot treatment for individual weeds should consider alternatives designed for those specific situations.
- Combines selective broadleaf weed control and fertilizer in one application
- Large bag covers up to 15,000 sq. ft., suitable for medium to large lawns
- WeedGrip technology helps granules adhere to weed leaves for better control
- Granular form is compatible with common broadcast or drop spreaders
- Not safe for several grass types including St. Augustine and bentgrass
- Requires specific temperature and moisture conditions for best results
Verdict: A convenient, proven one-step weed-and-feed for homeowners who want broadleaf weed control plus lawn feeding across large yards.
The Andersons Surge Weed & Feed 16-0-9 Granular Lawn Fertilizer (40 lb)
| Item Form | Granule |
|---|---|
| Coverage | 16000 square_feet |
| Unit Count | 640 Ounce |
| Active Ingredients | Herbicide |
The Andersons Surge Weed and Feed is a professional four‑way granular treatment that combines herbicide action with a 16-0-9 fertilizer to feed lawns while eliminating broadleaf weeds. It is applied with a broadcast spreader to established turf when broadleaf weeds are actively growing; best results come from mowing 1–2 days before application, applying to a damp lawn so granules adhere, and avoiding irrigation for at least 24 hours afterward. The product claims control of more than 250 common weeds and uses relatively small granules for wider coverage per square inch. In practice this means you can treat a large yard quickly and expect both greening and weed suppression over the season, including cooler spring and fall windows. Important limitations are that it is not suitable for certain turf types such as Floratam St. Augustine, dichondra, carpetgrass, creeping bentgrass, or lawns with desirable clovers, and you must follow timing and watering instructions to avoid reduced effectiveness or damage to new grass. For a homeowner focused on strong seasonal performance, this delivers broad control and fertilizer in one application.
Best for: Buyers who prioritize strong, season‑long weed control and want a professional‑grade product that also feeds established lawns and can treat a large area efficiently.
Less Ideal for: People with sensitive or excluded turf species, newly seeded/sodded lawns, or those who prefer spot treatments rather than whole‑lawn broadcast applications.
- Combines broadleaf weed control with fertilizer (16-0-9) for two functions in one application
- Covers up to 16,000 square feet, suitable for medium to large lawns
- Small granule size increases coverage per square inch for more uniform application
- Formulated to work through a wide part of the growing season, including cooler spring and fall conditions
- Not safe for specific turf types including Floratam St. Augustine, dichondra, carpetgrass, and creeping bentgrass
- Requires careful timing and withholding irrigation for at least 24 hours to be effective
- Not recommended for newly seeded or recently sodded lawns without reduced rates and waiting periods
Verdict: Choose this if you want a professional, large‑area weed‑and‑feed that delivers broadleaf control plus fertilizer in a single application.
BioAdvanced 5-in-1 Weed and Feed Granules (9.6 lb)
| Item Form | Granule |
|---|---|
| Coverage | 4000 square_feet |
| Active Ingredients | Dicamba, Quinclorac |
BioAdvanced 5-in-1 Weed and Feed is a granular lawn treatment that combines multiple herbicides with fertilizer so you can kill existing weeds and feed turf in a single application. You apply it with a broadcast or drop spreader to an established, dry lawn, then water in and avoid mowing for at least a day. The formula targets over 200 broadleaf weeds and large crabgrass and creates a soil barrier that helps prevent new listed weeds for up to six months while feeding and greening the lawn for about three months. Practical features include granular form for easy even coverage and instructions for follow-up watering and safety precautions. Important limitations are usual for combined herbicide-fertilizers: it is intended for established turf rather than newly seeded lawns, and precautions are needed around children, pets, and windy applications. It is not labeled for sale in all states and requires following label directions closely for best results.
Best for: Homeowners who want a low-effort, maintenance-friendly product to reduce separate purchases and applications and keep an established lawn greener while controlling common weeds.
Less Ideal for: People establishing a new lawn from seed, managing sensitive ornamentals near turf, or those who prefer non-chemical weed control methods.
- Combines weed control and fertilizer in one application for convenience
- Controls both broadleaf weeds and large crabgrass and helps prevent new weeds for up to six months
- Granular formula spreads evenly with a broadcast or drop spreader for uniform coverage
- Feeds and greens turf for up to three months after application
- Not suitable for newly seeded or delicate lawns where herbicides can inhibit germination
- Requires careful handling and exclusion of children and pets until treated areas are dry
Verdict: Use this product when you want one granular application to both kill common and crabgrass weeds and feed an established lawn for months of reduced maintenance.
Spectracide Weed & Feed 20-0-0 Ready-to-Spray, 32 oz
| Unit Count | 32 Fluid Ounces |
|---|---|
| Item Form | Spray |
| Coverage | 7500 square_feet |
| Active Ingredients | Nitrogen |
Spectracide Weed & Feed 20-0-0 is a hose-end spray that combines a broadleaf weedkiller with a high-nitrogen feed to treat lawns without mixing. You attach the QuickFlip sprayer to a garden hose, spray when weeds are actively growing, and the formula targets dandelion, chickweed, clover, plantain and similar weeds while delivering nitrogen to green up turf. The ready-to-spray design makes application fast for mid-season spot or whole-lawn treatments, and the stated coverage (up to 7,500 sq ft) suits small to medium yards. Important practical points: use on actively growing lawns, water 1–2 days before applying, and avoid application in extreme heat or before rain. Safety precautions are needed because the product can irritate skin and eyes and must be kept away from children and pets. This product is best for straightforward seasonal weed control and fertilization in established lawns rather than for new seedings or sensitive sites where reseeding is planned soon.
Best for: Buyers who want a quick, no-mix solution to reduce visible broadleaf weeds while boosting lawn greenness on an established lawn and who prefer an easy hose-end application.
Less Ideal for: Gardeners planning to seed or sod soon, or those with small specialty lawns that require low-nitrogen or organic treatments should consider other options.

Miracle-Gro Shake 'N Feed All Purpose Plant Food Plus Weed Preventer, 4.5 lb
| Item Form | Granules |
|---|---|
| Unit Count | 72 Ounce |
| Mixing Ratio | 10-10-10 |
| Coverage | Full |
| Target Species | plants |
This granular Shake 'N Feed combines a balanced 10-10-10 nutrient mix with a built-in weed preventer to feed vegetables, flowers, bulbs, shrubs and trees while reducing common garden weeds. Application is straightforward: sprinkle evenly over bare soil, gently rake it in and lightly water; one 4.5 lb container treats about 135 sq ft.

Choosing the Right Weed Feed Fertilizer: Key Factors to Consider
Nutrient Ratio and Release Type
The N-P-K ratio and whether nitrogen is fast- or slow-release determines how turf responds after application. Higher nitrogen levels encourage rapid green-up but increase the chance of scorching if turf is stressed or dry. Slow-release nitrogen provides steadier growth and reduces mowing frequency.
Consider soil test results and the seasonal growth pattern of your grass. In spring, a balanced or higher nitrogen feed can help recovery after winter. In early fall for cool-season lawns, moderate nitrogen with a slow-release component supports root development without excessive top growth.
Herbicide Active Ingredients and Target Weeds
Different weed feed products use different herbicide chemistries, which vary in what broadleaf species they control and how quickly symptoms appear. Some act on a wide range of common yard weeds such as dandelion, clover, and plantain, while others are better for specific problems.
Match the active ingredient profile to the dominant weeds in your lawn. Know that efficacy can depend on weed size and growth stage; younger, actively growing weeds are typically easier to control than mature plants.
Timing and Turf Type Compatibility
Application timing is critical for both feeding benefits and herbicide effectiveness. Cool-season grasses and warm-season grasses have different peak growth periods, and applying at the wrong time can reduce benefit or increase injury risk.
Follow label guidance about seasonal windows and avoid treating during drought or extreme heat. Some formulations are labeled safe for a wide range of turf types, while others advise against use on certain species; check compatibility before applying.
Application Method and Coverage Accuracy
Products come as granules, hose-end liquids, or concentrates for broadcast spreaders. Application uniformity matters because uneven coverage can leave patches of weeds or create fertilizer hot spots that burn grass.
Consider the tools you have: a broadcast spreader offers consistent granule distribution when calibrated, while hose-end applicators simplify liquid mixing but can be sensitive to water pressure and speed. Clear label mixing rates and spreader settings make precise application much easier.
Turf Safety and Environmental Precautions
Combined weed-and-feed products contain herbicides that can harm non-target plants if they drift or runoff. They may also affect pollinators when applied to flowering weeds. Understanding safety intervals for irrigation and pet access helps reduce unintended impacts.
Look for products with specific re-entry, mowing, and irrigation instructions. Avoid application before heavy rain or on sloped yards without buffer zones to minimize runoff into gardens or waterways.
Longevity of Feeding and Weed Control
Some weed feed formulations provide short-term green-up with minimal residual weed suppression, while others offer weeks to months of control and steady nutrient release. Longevity affects how soon you may need to retreat and how the lawn will perform through the season.
Match expected duration to your maintenance plan. If you prefer fewer treatments, choose longer-acting feeds and herbicides, but remember longer persistence can mean stronger environmental precautions.
When to Apply Weed Feed
Timing depends on your grass species and local climate. For cool-season lawns, late summer into early fall is often the best window because the grass is actively growing and can recover while weeds are still vulnerable. For warm-season lawns, spring to early summer when the turf is greening works best, but avoid application during peak heat or drought stress.
- Avoid treatment during or immediately before heavy rain.
- Do not apply during drought or when turf is wilted to reduce burn risk.
- Follow label guidance on minimum temperatures and growth stage for best herbicide uptake.
Preparing Your Lawn Before Treatment
Mow to a normal height and remove debris so granules or spray reach weed foliage. Water a few days before application if the lawn is dry, but do not irrigate immediately prior to applying products that require dry leaf surfaces for the herbicide to stick.
- Perform a spot weed assessment to confirm target species.
- Calibrate spreader or tester-run a hose-end applicator to confirm even delivery.
- Wait the recommended interval after recent fertilizer or pesticide applications to avoid overdosing.
Application Tools and Best Practices
Choose the application format that fits your comfort level and lawn size. Granules are forgiving and easy to store, while liquid hose-end systems can cover large areas quickly if mixed correctly. Always measure product and water precisely and overlap passes slightly to avoid streaking.
- Calibrate your spreader with the product label's setting and test on a driveway first.
- Wear gloves and eye protection when handling concentrates.
- Rinse equipment away from flower beds and vegetable gardens.
Managing Treated Areas and Expectation Setting
Herbicide effects on broadleaf weeds can take from a few days to several weeks to show visible browning. Resist the urge to re-treat immediately; follow the label for retreatment intervals. Fertilizer response is usually visible as greener, denser turf within one to three weeks depending on formulation.
- Keep pets off treated areas until the product dries or until the label says it is safe.
- Mow at normal heights but avoid bagging clippings shortly after treatment unless label allows.
- For persistent weed problems, integrate cultural practices like improved mowing, aeration, and overseeding rather than relying on repeated chemical treatments.
Environmental Considerations and Pollinator Safety
Be cautious when applying weed-and-feed products near flowering plants, gardens, or water features. Some herbicides can be toxic to aquatic life or pollinators when applied to blooms or when runoff occurs. Follow buffer and irrigation guidance to minimize risk.
- Avoid treating lawns with blooming weeds to reduce pollinator exposure.
- Do not apply before heavy rain to prevent runoff into storm drains.
- Store unused product safely and dispose of empty containers according to local regulations.
How We Chose the Best Weed Feed Fertilizer
We narrowed options to products formulated specifically for combined fertilization and post-emergent broadleaf weed control for turf. Editorial filters emphasized proven nutrient ratios for common lawn grasses and clearly labeled herbicide active ingredients suited to residential turf. We prioritized products with application windows that match cool- and warm-season grass cycles, and those offering clear spreader or hose-end instructions to reduce misuse. Evaluation criteria focused on nutrient balance and release type, weed control spectrum and efficacy against typical broadleaf species, turf safety and burn risk, ease and precision of application, and longevity of both feeding and weed suppression. We also screened for clear label directions and realistic environmental precautions. Excluded items included straight fertilizers without herbicide, products intended for ornamental beds, and formulations lacking explicit turf safety guidance. The goal was to surface practical choices for gardeners who need a combined feeding and weed-control approach rather than standalone lawn amendments.
FAQ
Can I use weed feed on newly seeded lawns?
Usually not. Many weed feed formulations are not safe for newly seeded or freshly sodded lawns because herbicides and high nitrogen can stress young grass. Check label timing, but most recommendations delay application until seedlings are well established, often several months.
Will weed feed kill crabgrass and grassy weeds?
Most weed feed products target broadleaf weeds and are not effective against grassy weeds like crabgrass. For grassy weed control you typically need a pre-emergent or a targeted grass herbicide. Cultural practices and proper fertilization can also reduce grassy weed pressure.
How long after rain should I wait to apply weed feed?
Wait until leaves are dry and soil is not saturated. Heavy rain shortly after application can reduce effectiveness and increase runoff risk. Follow label advice for reapplication intervals if rain occurs within a short window after treatment.
Is it safe to use weed feed around flower beds and vegetable gardens?
Exercise care. Drift or runoff can harm ornamentals and edibles. Use buffer zones, avoid application on windy days, and rinse equipment away from planting beds. Consider spot-treating weeds or using more targeted herbicides near sensitive plants.
Can I water my lawn after applying weed feed?
Some products require a period without irrigation for the herbicide to be absorbed, while others recommend light watering to move nutrients into the soil. Always follow the label instructions for irrigation timing to balance uptake and runoff prevention.
How often should I reapply a weed feed product?
Reapplication depends on the product's labeled residual period and your lawn's weed pressure. Many combined feeds are applied once per season, but persistent problems may need spot treatments or a different integrated approach. Respect label instructions on retreatment intervals.
Final Verdict
Choose a weed feed fertilizer that matches your grass species, timing window, and weed spectrum. Prioritize products with an appropriate nutrient mix and a herbicide profile that targets the weeds you actually have. Consider application method and label clarity to reduce the risk of turf injury and environmental harm. Balance the desire for quick green-up with turf safety and longevity: slow-release nitrogen and clear application instructions often give more consistent, lower-risk results. Use the decision factors above to pick the best option for your lawn maintenance plan.
