You’ll get a single-step granular product combining a 20-0-3 starter fertilizer with Dimension (dithiopyr) to suppress crabgrass and feed early-season turf. It reliably blocks germination when applied within labeled windows and tolerates some late applications, while boosting shoot vigor with quick nitrogen and modest potassium. Calibrate your spreader, avoid seeding during the preemergent window, and follow label coverage for your region. Continue for application rates, timing nuances, and alternative options.
Some Key Takeaways
- Combines dithiopyr (Dimension) preemergent with a 20-0-3 fertilizer for one-step crabgrass prevention and early-season feeding.
- Provides reliable season-long crabgrass suppression when applied at labeled timing and calibrated spreader rates.
- Tolerates slightly later application than some preemergents but still requires avoidance of overseeding during the preemergent window.
- Delivers quick-available nitrogen and modest potassium to boost early turf vigor, color, and drought recovery.
- Best for homeowners wanting a simple granular solution; consider resistance risk and alternatives for controlled-release nutrition.
Quick Verdict: Is Fertilome Crabgrass Preventer Plus Lawn Food Worth Buying?
Usually, you’ll find Fertilome Crabgrass Preventer Plus Lawn Food worth buying if you want a combined preemergent and fertilizer—its 20-0-3 granular formula with Dimension offers season-long crabgrass suppression plus nitrogen and potassium to strengthen turf. You’ll appreciate clear specs, predictable application windows, and a single-step program that simplifies maintenance for your group. Run a cost comparison against separate preemergent and fertilizer buys; you’ll often save time and money while reducing handling complexity. Check user testimonials for consistent reports of healthy, uniform lawns and delayed weed emergence. Adopt it if you value efficiency, community-tested performance, and labeled application guidance. It’s ideal for homeowners who maintain their lawn and landscape and prefer granular lawn fertilizers for ease of application.
How Well It Prevents Crabgrass and Controls Other Weeds
Having decided the combined fertilizer/preemergent approach suits your lawn, evaluate efficacy by focusing on active ingredient performance and application timing. You’ll rely on Dimension (dithiopyr) to interrupt crabgrass germination and suppress many annual grasses and selected broadleaf weeds. When applied within the labeled window and at recommended rates it provides reliable preemergent control, even with the product’s later-application tolerance. Monitor for localized crabgrass resistance and adjust cultural practices accordingly. Consider potential postemergent interactions if you plan follow-up treatments; tank-mixing or sequential herbicides can alter efficacy and turf safety. Follow label specifics to maintain predictable control. Our site offers a range of crabgrass barrier products for homeowners who maintain their lawn and landscape.
Fertilizer Performance: Lawn Health, Timing, and Coverage Details
When you apply Fertilome Crabgrass Preventer Plus Lawn Food on schedule and at the label rates, its 20-0-3 granular formula delivers a quick-available nitrogen boost and a modest potassium supply to strengthen turf, promote color, and improve stress tolerance without adding phosphorus. You’ll see accelerated shoot vigor and denser canopy that shades soil, reducing weed niches and supporting a resilient soil microbiome. Timing aligns nutrient availability with early growth, maximizing uptake and minimizing leaching. Coverage guidance varies by Dimension rate, region, and grass type; follow label coverage to guarantee uniform distribution. Improved potassium contributes to drought tolerance and recovery. Many homeowners find these products helpful for maintaining healthy lawns when they follow application rates.
How to Apply It Correctly (Rates, Timing, and Common Mistakes)
To convert the fertilizer’s growth benefits into reliable weed control, you must match rates and timing to your grass type and regional germination windows. Calibrate application equipment—broadcast or drop spreaders—to deliver label-specified pounds per 1,000 sq ft; incorrect spreader speed causes under- or over-application. Apply as a preemergent before soil temperatures trigger crabgrass; the product tolerates later application but follow regional cues. Avoid reseeding within the preemergent window due to seed interaction; postpone overseeding or use a different strategy. Common mistakes: uneven passes, ignoring label rates, and applying before heavy rain that can cause runoff or reduced efficacy. Also consider your lawn’s soil type and grass species when planning applications for best results, especially regional germination windows.
Who Should Buy It and Alternatives to Consider
If you run a cool- or warm-season lawn and want a single-pass product that combines a preemergent herbicide (Dimension) with a high-nitrogen fertilizer, Fertilome Crabgrass Preventer Plus Lawn Food is a practical choice—especially if you need a window of application flexibility and steady-seasonal feeding. You should buy it if you value simplicity, want reliable crabgrass suppression, and prefer a granular, ready-to-apply solution. It’s attractive to budget shoppers seeking combined value and to homeowners managing mixed turf types. Check region suitability and label rates first. Alternatives: separate preemergent-only products, timed liquid feeds, or professional overseeding services. Consider pairing this product with controlled-release fertilizers for more consistent nutrient delivery over the season.
Some Questions Answered
Is This Product Safe for Children and Pets After Application?
You should keep children and pets off the treated area until the granules have been watered in and the lawn is dry; that minimizes child safety and pet exposure risks. Follow the label for specific re-entry times and watering instructions. Wear gloves when applying, store product securely, and remove pets and kids during application. If accidental ingestion or significant exposure occurs, contact poison control or your veterinarian immediately for guidance.
Can I Mix It With Other Lawn Treatments or Fertilizers?
Yes — you can mix it with some treatments, but you’ll need to follow label guidance to avoid incompatible chemical interactions and make certain compatible timing. Read product directions and don’t combine with other herbicides unless label permits; tank-mixing fertilizers with the granules is generally unnecessary. When in doubt, test a small area, contact the manufacturer, and space applications so timing aligns with label-specified intervals to protect efficacy and turf health.
How Long Does a 16 Lb Bag Typically Last on My Yard Size?
A 16 lb bag will typically cover about 5,000–7,500 sq ft depending on application rate and Desired Dimension rate. Use the label’s application rate to calculate your coverage estimate: divide total coverage per bag by your lawn square footage. If you apply at the higher Dimension rate you’ll get nearer 5,000 sq ft; at a lower rate you’ll approach 7,500 sq ft. Reapply only per label timing and safety instructions.
Does It Stain Concrete, Driveways, or Clothing?
No, it typically won’t stain concrete, driveways, or clothing if you handle it properly and clean spills promptly. You’ll appreciate its staining resistance when applied dry; granules seldom leave marks. Still, perform basic fabric testing on an inconspicuous garment before exposure, and sweep or hose off any granules from hard surfaces quickly. Wear gloves and wash contaminated clothing separately to maintain safety and community-minded care for shared spaces.
Is a Runoff or Water Restriction Period Required After Use?
Yes — you should observe water restrictions after application. You’ll avoid irrigation for the initial period specified on the label so the product stays on the turf surface to provide preemergent activity; brief light watering only when the label requires incorporation. Follow irrigation timing and any local water restrictions precisely. By doing so you’ll maximize efficacy, comply with regulations, and protect shared community resources while maintaining lawn health and belonging.
