7 Best Crabgrass Preventer And Fertilizer | Stop Weeds Now

Our readers keep the lights on and my smoothie glass nicely filled. As an Amazon Associate, I earn from qualifying purchases.

Few lawn-care frustrations match the sight of crabgrass spreading through a carefully maintained yard. This aggressive weed exploits thin or stressed turf, germinating in bare spots and outcompeting desirable grass for moisture and nutrients, leaving homeowners with a patchy, unkempt appearance that requires season-long management. A targeted strategy using a combination product that both feeds the lawn and halts weed germination is the smartest approach for a thick, healthy turf that naturally resists invasion.

I’m Mohammad Maruf — the founder and writer behind WellFizz. My market research for this guide involved cross-referencing active-ingredient profiles, nitrogen release rates, and coverage-area claims across dozens of granular and liquid formulations to identify the most effective crabgrass preventer and fertilizer options available.

After reviewing the leading products on the market, I’ve assembled a focused list of proven weed-control solutions. This guide evaluates seven top-tier formulations to help you find the best crabgrass preventer and fertilizer that matches the specific needs of your grass type, soil conditions, and seasonal schedule.

How To Choose The Best Crabgrass Preventer And Fertilizer

Crabgrass preventer and fertilizer combos pack two critical lawn-care functions into a single application: they feed your existing turf while laying down a chemical barrier that stops crabgrass seeds from sprouting. Choosing the wrong product can mean wasted money, damaged grass, or zero weed control. Focus on these three factors when shopping.

Active Ingredient: Dimension vs. Barricade vs. Mesotrione

The herbicide inside the bag determines what it kills and how long it lasts. Dimension (dithiopyr) offers both pre- and early post-emergent control, allowing a wider application window. Barricade (prodiamine) is a heavy-duty pre-emergent that stays active for months and is ideal for early-spring prevention. Mesotrione works both as a pre-emergent and a post-emergent, bleaching weeds white before they die, but it can also temporarily discolor your lawn if applied improperly.

N-P-K Ratio and Feeding Strategy

The three-number analysis on the bag tells you how much nitrogen, phosphorus, and potassium the product delivers. A spring preventer should lean on nitrogen (the first number) for green-up but avoid too-high levels that send top growth soaring at the expense of roots. Ratios like 20-0-3 or 26-0-6 provide slow-release nitrogen without excess phosphorus, which is already abundant in most soils and can run off into waterways.

Coverage Area and Granule Size

One bag may claim to cover 5,000 square feet while a heavier bag covers only 4,500 square feet — the difference lies in the concentration of active ingredients and the filler weight. Smaller granule sizes (like The Andersons DG Technology) dissolve faster and deliver more uniform coverage, reducing streaks and bare spots. Always measure your lawn and match product coverage to avoid under- or over-application.

In‑Depth Reviews

Best Overall

1. The Andersons Premium Crabgrass Preventer Plus Fertilizer 26-0-6

26-0-66,000 sq. ft.

The Andersons 26-0-6 brings Dimension (dithiopyr) as its active ingredient, offering up to four months of pre-emergent protection against crabgrass, goosegrass, and more than two dozen weed species. The high first-number nitrogen ratio provides an immediate spring green-up while the slow-release portion feeds the lawn steadily for extended growth without a sudden flush.

Coverage of 6,000 square feet from a 17-pound bag is generous, and the granular formulation spreads evenly with a rotary spreader. Users report a visibly greener lawn within two weeks and near-total crabgrass suppression when applied before soil temperatures reach 55°F.

The product is not labeled for sale in New York, Florida, California, or Indiana. It should also be avoided on dichondra and bentgrass lawns, as these turf types are sensitive to the herbicide. A lighter spreader setting is recommended to avoid overlapping and potential turf burn.

Why it’s great

  • Four months of pre-emergent protection with a wide application window
  • Quick- and slow-release nitrogen for fast green and sustained feeding
  • Generous 6,000 sq. ft. coverage from a single bag

Good to know

  • Restricted in some states; check local regulations before ordering
  • Overlapping passes can cause turf burn — calibrate spreader carefully
  • Not safe for bentgrass or dichondra lawns
Professional Choice

2. The Andersons 18-0-4 Barricade Fertilizer with Pre Emergent Weed Control

18-0-4Prodiamine

This Barricade-based formulation uses prodiamine at 0.426% concentration, a heavy-duty pre-emergent that targets crabgrass, poa annua, goosegrass, henbit, and nearly 30 other grassy and broadleaf weeds. Unlike Dimension, prodiamine offers no post-emergent control, so timing the application before soil temperatures hit 55°F is essential for success.

The patented DG Technology dispersible granules dissolve rapidly upon watering, moving the herbicide directly into the soil profile for maximum root-zone impact. Small particle size means more granules per square inch, reducing the risk of missed spots. The 18-0-4 fertilizer ratio delivers moderate nitrogen for steady greening without excessive top growth.

This product is designed for early spring and fall applications and works well on zoysia, Bermuda, tall fescue, and Kentucky bluegrass. It will not eliminate existing weeds — it is purely a preventative barrier. Users note that precise spreader calibration is critical to avoid over-application.

Why it’s great

  • Professional-grade prodiamine provides long-lasting weed prevention
  • DG Technology ensures rapid soil penetration and uniform coverage
  • Excellent for zoysia and Bermuda grass lawns

Good to know

  • No post-emergent action; cannot kill existing crabgrass
  • Overpriced compared to some equally effective alternatives
  • Requires careful timing for optimum results

3. Lawn Synergy 13-0-10 Pre-Emergent Lawn Fertilizer

13-0-1012,500 sq. ft.

The 50-pound bag from Lawn Synergy delivers the best coverage-per-dollar ratio in this lineup, treating up to 12,500 square feet. The 13-0-10 analysis provides a balanced feeding with slow-release nitrogen for continuous growth and potassium for root strength and stress tolerance.

Recommended for two spring applications on cool-season lawns and one spring plus one fall application on warm-season turf, this product works across all grass types. User photos show dramatic greening after a single application, suggesting the nitrogen source is readily available for uptake.

While the exact active ingredient is not named in the product data, reviewers confirm effective crabgrass and weed prevention when applied before germination. The heavy bag size means it is best suited for homeowners with larger lawns who want to reduce the number of refills.

Why it’s great

  • Massive 12,500 sq. ft. coverage from a single bag
  • Slow-release nitrogen for consistent feeding without a flush
  • Works on all grass types with flexible application timing

Good to know

  • Heavy 50-pound bag may be cumbersome for some users
  • Active ingredient not clearly specified on product details
  • Requires two applications per season for best results
Season Extender

4. Jonathan Green Veri-Green Crabgrass Preventer Plus Fertilizer 20-0-3

20-0-35,000 sq. ft.

The Jonathan Green Veri-Green formulation feeds lawns for up to three months with its 20-0-3 analysis, combining a high-nitrogen quick-release component with a slow-release source for sustained feeding. It provides both pre- and post-emergent crabgrass control, giving a wider application window than strict pre-emergents.

Beyond crabgrass, it targets goosegrass, dallisgrass, chickweed, henbit, oxalis, and spurge when applied before germination. The granules do not stain hands, shoes, or walkways, making cleanup simpler after spreading. Coverage is standard at 5,000 square feet from a 15-pound bag.

One important limitation: this product cannot be used at the same time as seeding a new lawn. The herbicide will prevent new grass seed from germinating along with the weeds. Application timing in early spring, before soil temperatures reach 55°F, is critical for maximum effectiveness.

Why it’s great

  • Three months of slow-release feeding with strong nitrogen content
  • Pre- and post-emergent crabgrass control for flexible timing
  • Non-staining granules simplify application cleanup

Good to know

  • Cannot be used when seeding a new lawn
  • Standard 5,000 sq. ft. coverage requires multiple bags for larger lawns
  • Higher price point compared to some mid-range competitors
Late-Window Hero

5. Preen Lawn Crabgrass Control (15 lb)

Dithiopyr5,000 sq. ft.

Preen Lawn Crabgrass Control uses dithiopyr (the same active ingredient found in Dimension) and offers a unique advantage: it can be applied up to four weeks after crabgrass has emerged, thanks to its early post-emergent activity. This makes it a forgiving option for homeowners who miss the ideal pre-emergent window.

The product prevents crabgrass all season and controls more than 40 common lawn weeds. It is safe for both cool- and warm-season grasses, including creeping bentgrass, Kentucky bluegrass, fine fescue, tall fescue, perennial ryegrass, bahiagrass, bermudagrass, buffalograss, carpetgrass, centipedegrass, St. Augustinegrass, and zoysiagrass when applied as directed.

Some users report excellent results with fewer applications than competing brands like Scotts, while a minority note that it failed to prevent crabgrass in their specific conditions. Proper watering after application is essential to activate the herbicide barrier.

Why it’s great

  • Can be applied up to 4 weeks after crabgrass emerges
  • Controls over 40 weed species for comprehensive lawn protection
  • Safe on almost all cool- and warm-season grass types

Good to know

  • Inconsistent results reported by some users
  • Requires thorough watering within 24 hours of application
  • Not suitable for use during summer dormancy
Budget Pick

6. Hi-Yield Turf & Ornamental Weed & Grass Stopper (12 lbs)

Dimension5,000 sq. ft.

Hi-Yield’s granular formula contains Dimension and provides superior control of crabgrass, goosegrass, and many other annual grass and broadleaf weeds. It can be applied up to four weeks later than other pre-emergent crabgrass products, offering a similar late-window flexibility to the Preen option at a lower cost.

The 12-pound bag covers 5,000 square feet and is intended for use on ornamental landscape areas, established lawns, and ornamental turf. Users report excellent results against stubborn goosegrass and henbit when applied after the growing season and watered in thoroughly.

A notable complaint concerns inconsistent bag weights — some deliveries arrived lighter than the advertised 12 pounds. Timing remains critical, and consistent use over two or more years is recommended for full eradication of persistent weed populations.

Why it’s great

  • Contains Dimension for both pre- and early post-emergent control
  • Can be applied up to 4 weeks later than other pre-emergent products
  • Affordable option with effective goosegrass and henbit control

Good to know

  • Inconsistent bag weights reported by some users
  • Missed spring application window significantly reduces first-year results
  • Requires multi-year consistent use for full effectiveness
Selective Specialist

7. Liquid Harvest Mesotrione (8 oz)

Mesotrione8 oz concentrate

This liquid concentrate delivers mesotrione, the same active ingredient found in Tenacity. It works both as a pre-emergent, preventing crabgrass seed germination, and as a post-emergent, bleaching existing weeds white before they die within two to three weeks. It targets 46 broadleaf species and grasses.

Suitable for Kentucky bluegrass, centipede grass, buffalo grass, tall fescue, perennial ryegrass, fine fescue, and St. Augustine grass (sod only), but must be avoided on bentgrass, poa annua, kikuyugrass, zoysiagrass, seashore paspalum, and bermudagrass. Activation requires 0.15 inches of water within 10 days if no rainfall occurs.

The product is highly concentrated, and users strongly recommend using a backpack or pump sprayer with a dye indicator to avoid overlap. Over-application can discolor or temporarily stunt healthy turf. For best results, combine with a fall fertilizer follow-up for cool-season lawns.

Why it’s great

  • Both pre- and post-emergent activity for flexible weed control
  • Effective against 46 weed species including clover and wild violet
  • Safe on centipede grass and other sensitive warm-season turf

Good to know

  • Can temporarily discolor healthy turf if over-applied
  • Not safe for bentgrass, zoysia, or bermudagrass
  • Requires precise sprayer calibration and dye indicator

FAQ

When should I apply crabgrass preventer and fertilizer in spring?
Apply when soil temperatures reach 55°F at a 4-inch depth for three consecutive days. This typically aligns with when forsythia bushes bloom or when lilac leaves reach the size of a mouse ear. Applying too early wastes product; applying too late misses the pre-emergent window.
Can I use crabgrass preventer and fertilizer on a newly seeded lawn?
No. Most pre-emergent herbicides, including Dimension, Barricade, and mesotrione, prevent all seeds from germinating — including grass seed. Wait at least 8 weeks after seeding or use a product formulated for new lawns. If you plan to seed, skip the preventer and use a post-emergent option later.
Is liquid or granular crabgrass preventer more effective?
Both can be effective when applied correctly. Granular formulations are easier to apply with a spreader and provide even coverage across large areas. Liquid concentrates like mesotrione require sprayer calibration and are better suited for spot treatments. Granular products generally offer a longer residual effect.
Can I use a crabgrass preventer on St. Augustine grass?
Yes, but choose carefully. Preen Lawn Crabgrass Control is labeled safe for St. Augustine grass. Mesotrione can be used on sod-only St. Augustine. Avoid products containing atrazine or simazine unless specifically labeled for St. Augustine. Always check the product label for your specific turf type.
Does crabgrass preventer expire or lose effectiveness over time?
Yes. Most granular formulations have a shelf life of one to two years when stored in a dry, temperature-stable environment. Heat and humidity accelerate degradation. If the granules clump, smell off, or fail to dissolve properly, the product may have lost potency. Always check the manufacture date on the bag.

Final Thoughts: The Verdict

For most users, the best crabgrass preventer and fertilizer winner is the The Andersons Premium 26-0-6 because it combines Dimension’s forgiving application window with a powerful 26-0-6 fertilizer for fast green-up and extended feeding. If you want a pure pre-emergent with professional-grade longevity, grab the The Andersons 18-0-4 Barricade. And for large lawns on a budget, nothing beats the coverage value of the Lawn Synergy 13-0-10.
