Staring down a lawn overtaken by crabgrass, dandelions, or creeping charlie? Granular herbicides deliver that control by binding to the soil or foliage, but not all granules work the same way — some prevent weeds before they sprout, others kill what’s already growing, and a few do both.
I’m Rikta — the founder and writer behind Lawn Gear Lab. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
Below, I break down four granular herbicides covering different yard sizes and weed types, so you can match the right product to your specific grass and weed problem. This is the best granular herbicide guide for homeowners who want a clear, honest comparison without the marketing fluff.

How To Choose The Best Granular Herbicide
Granular herbicides come in two main types: pre-emergent formulas that create a chemical barrier in the soil to stop weed seeds from germinating, and post-emergent formulas that kill weeds already above the surface. Some combine fertilizer with the herbicide in a weed-and-feed product. Your choice depends on whether you are preventing weeds or killing existing ones, the size of your lawn, and which grass type you grow.
Pre-emergent vs. Post-emergent: timing is everything
Pre-emergent herbicides, like those with prodiamine (found in The Andersons Barricade), must be applied before weed seeds germinate — typically in early spring or fall. They stop weeds like crabgrass and poa annua from ever appearing. Post-emergent herbicides, like the 2,4-D blend in The Andersons Professional Surge, kill weeds that are already visible. If you apply a pre-emergent too late, it won’t stop existing weeds; if you apply a post-emergent too early, new weeds may sprout behind it.
Coverage area and bag size match your yard
Granular herbicides are sold by weight, with coverage rates given in square feet per bag. A 10-pound bag covering 1,000 square feet suits small areas like gravel driveways or fence lines. A 40-pound bag covering 16,000 square feet fits a quarter-acre lawn. Buying a bag too small means multiple applications; one too large may leave you storing leftover product that loses potency.
Grass type compatibility matters
Not every granular herbicide works on every grass. Some products explicitly warn against use on St. Augustinegrass (including Floratam), dichondra, carpetgrass, or bentgrass. Always check the label for your specific grass type — applying the wrong formula can damage or kill your lawn. The data shows Scotts Turf Builder Weed & Feed5, for example, should not be used on St. Augustinegrass or bentgrass lawns.

In‑Depth Reviews
1. The Andersons Professional Surge Weed and Feed 16-0-9 Post-Emergent (40 lb)
The heavy hitter that kills 250+ weeds while feeding your lawn thick and green.
This professional-grade post-emergent delivers a one-two punch. The 16-0-9 fertilizer formula feeds your lawn to build thicker, greener turf, while the four-way herbicide blend eliminates over 250 common weeds including dandelions, clover, chickweed, and plantain. The 40-pound bag covers up to 16,000 square feet — more than any other product here, covering 16.0x the area of the Image Noxall granules (1,000 sq ft) from a single bag.
Buyers report it works on stubborn creeping charlie (a fast-spreading ground ivy) where other products failed. One reviewer noted, “I tried a lot of pre emergents and could not prevent crabgrass or kill creeping charlie. I used this product this year and so far I see no creeping charlie.” The small particles mean more coverage per square inch, and the formula performs across the full growing season, even in the cooler temperatures of spring and fall. A word of caution: it is not for use on Floratam St. Augustine grass, dichondra, carpetgrass, creeping bentgrass, or turf containing desirable clovers.
Unlike the Scotts Weed & Feed5, which struggled with crabgrass and clover according to reviewers, The Andersons Surge targets a broader weed spectrum. It is the right choice if you have an established lawn overrun with broadleaf weeds and want one application to both kill and feed across a large area.
What stands out
- Eliminates over 250 common broadleaf weeds
- 16,000 sq ft coverage from a single bag
- 16-0-9 fertilizer feeds lawn while killing weeds
- Owners mention success with creeping charlie
Know the limits
- Cannot use on Floratam St. Augustine or dichondra
- Some buyers noted no noticeable difference from cheaper brands
- Not sold in NH or WA
Reach for this if: you have a large lawn (up to 16,000 sq ft) with broadleaf weeds like dandelions, clover, or creeping charlie and want a weed-and-feed that does both jobs well.
Look elsewhere if: you grow Floratam St. Augustine or dichondra, or you only need a pre-emergent to stop weeds before they sprout.
2. The Andersons 18-0-4 Barricade Fertilizer with Pre Emergent Weed Control (18 lb)
The early-season barrier that stops 30 weed types before they break the surface.
This is a pre-emergent, which means it prevents weeds rather than killing existing ones. The active ingredient is prodiamine at 0.426%, a professional-grade compound that stops crabgrass, poa annua, goosegrass, henbit, and 26 other grass and broadleaf weeds from germinating. The 18-0-4 fertilizer feeds your lawn for deep green color and healthy growth without excessive top growth. One 18-pound bag covers 5,000 square feet.
The Andersons uses patented DG Technology (dispersible granule, meaning the tiny granules dissolve quickly upon watering) to move the prodiamine (a pre-emergent herbicide that stops weed seeds from sprouting) into the soil for maximum impact. Buyers consistently praise the results — one reviewer wrote it “prevents weeds effectively before they start; fertilizer gives deep green, healthy lawn without excessive growth; granules spread evenly; results in fewer weeds and thicker, stronger grass.” Another reviewer on a zoysia grass lawn in Texas noted it’s easy to apply with a Scotts spreader.
The key trade-off is timing: this product will not eliminate existing weeds. You must apply it in early spring or fall before weed seeds germinate. Like the Scotts Weed & Feed5, it contains fertilizer, but its primary job is prevention, not cure. For lawns already thick with weeds, pair this with a post-emergent product later in the season.
Stop-weeds-before-they-start: If you want fewer weeds overall without constantly battling visible growth, apply this in early spring. Customers note it is “overpriced for what you get” compared to some alternatives, but the combination of prodiamine and slow-release fertilizer in one bag saves a spreading pass.
Ideal for: homeowners who want to prevent crabgrass, poa annua, and henbit on a lawn up to 5,000 sq ft, especially those with zoysia, Bermuda, or fescue.
skip it if: you already have visible weeds — you need a post-emergent first. Also skip if your lawn is larger than 5,000 sq ft without wanting to buy multiple bags.
3. Scotts Turf Builder Weed & Feed5 (33.95 lb)
The household name that nails dandelions but lets some crabgrass slip through.
Scotts Turf Builder Weed & Feed5 combines a post-emergent weed killer with lawn fertilizer in one granule. It controls over 50 listed lawn weeds, including clover, dandelion, plantain, morningglory, chicory, eveningprimrose, and purslane. The 33.95-pound bag covers 12,000 square feet, and the formula works best when daytime temperatures stay between 60°F and 90°F. It is designed for Bahiagrass, Bermudagrass, Bluegrass, Centipedegrass, Fescue, Ryegrass, and Zoysiagrass — but do not use it on St. Augustinegrass (including Floratam), Dichondra, Carpetgrass, or Bentgrass.
Reviewers report mixed results on tough weeds. One buyer mentioned it “didn’t kill my crab grass or clover but no dandelions and really great fertilizer.” Others praised it for killing dandelions and greening up the lawn effectively. The product requires wet granules to stick to weeds — do not water for 2-3 days after application, and reapply if it rains, as one helpful reviewer emphasized. Unlike The Andersons Barricade (a pre-emergent), this is strictly post-emergent: it kills weeds that are already visible but will not prevent new ones from germinating.
At 33.95 pounds covering 12,000 square feet, it offers solid coverage for a medium lawn but falls short of The Andersons Professional Surge’s 16,000-square-foot reach per bag. If your primary weed is dandelion and you want a simple bag that fertilizes while it kills, this is a reliable option.
Why it works
- Controls over 50 listed weeds including dandelion, clover, plantain
- Thickens lawn to crowd out future weeds
- Easy application with a Scotts spreader
- Reviewers point out beautiful dark green Bermuda grass results
Where it falls short
- Does not control crabgrass or clover well, per some reviews
- Not safe for St. Augustinegrass or bentgrass lawns
- Requires careful watering timing for best results
Best suited for: homeowners with Bermuda, fescue, or bluegrass lawns dealing with dandelions and broadleaf weeds who want the simplicity of a weed-and-feed product.
Not ideal if: your lawn is St. Augustine or you are battling crabgrass — you will need a different active ingredient for that.
4. Image Herbicides Noxall Weed & Grass Killer Granules 10LB
The scorched-earth option for gravel drives, fence lines, and bare-soil areas.
This is a non-selective granular herbicide, meaning it kills any vegetation it contacts — grass, weeds, everything — down to the root. It is not for your lawn. It is designed for gravel walks, along fences, around buildings, under decks, and other areas where you want nothing green growing for up to one year. The 10-pound bag covers 1,000 square feet, making it the smallest coverage option here by a significant margin — The Andersons Professional Surge covers 16.0x more area for total vegetation control in lawn-like settings.
Buyers who used it in the right conditions report success. One said it “cleared my rock driveway.” Another noted it “stops the weeds.” The product targets poa annua, chickweed, spurge, fescue, and dandelion. But there is a real caution: one reviewer applied it “at several times the suggested rate before light rain” and found it “completely ineffective, no grass kill” — they called it expensive. Additionally, the granules are very fine and have a strong odor that can permeate a storage area if the bag is not sealed tightly, as another buyer mentioned.
Unlike all other products on this list, Noxall is not a lawn herbicide. It is a total vegetation killer for bare-ground applications. If you need to clear a patio, driveway, or fence line and keep it clear for up to a year, this fits. If you want to selectively kill weeds in your lawn, choose one of the other three options above.
For bare ground only: This is a total-kill product — do not use it on or near lawn grass you want to keep.
Grab this for: gravel driveways, patios, fence lines, or under decks where you want zero vegetation for up to a year.
Avoid for: any lawn area or around desirable plants — it kills everything.
Understanding the Specs
Pre-emergent vs. Post-emergent
A pre-emergent herbicide (like prodiamine in The Andersons Barricade) stops weed seeds from germinating — it creates a barrier in the soil that kills the seedling as it tries to sprout. A post-emergent herbicide (like the 2,4-D blend in The Andersons Professional Surge) kills weeds that are already visible above the soil. Pre-emergents must be applied before weeds appear; post-emergents work on existing weeds but do not prevent new ones.
Coverage area and bag weight
Coverage is listed in square feet per bag — the area the product will treat at the recommended rate. A 40-pound bag covering 16,000 square feet suits a quarter-acre lawn (about half a football field). A 10-pound bag covering 1,000 square feet is for small areas like a gravel driveway or fence line. Always measure your lawn or target area before buying — applying too thin reduces effectiveness, applying too thick wastes product and may harm grass.

Final Thoughts: The Verdict
For most buyers, the best granular herbicide winner is the The Andersons Professional Surge Weed and Feed 16-0-9 because it eliminates over 250 broadleaf weeds while feeding your lawn across 16,000 square feet from one bag. If you want to prevent weeds before they start on a smaller lawn, grab the The Andersons 18-0-4 Barricade. And for total vegetation kill on gravel drives or fence lines, nothing covers the ground like the Image Herbicides Noxall Granules.
