LESCO Fertilizer Complete Buyer Guide 2026: Which Product Is Right for You?
If you’re a lawn care professional, golf course superintendent, or grounds manager, you’ve likely used LESCO fertilizer products at some point in your career. LESCO is one of the most trusted names in professional turf care — and for good reason. This guide breaks down the LESCO fertilizer lineup so you can choose the right product for your application.
What Is LESCO Fertilizer?
LESCO (Lawn, Garden, and Agricultural Products) was originally founded in 1962 as a manufacturer and distributor of professional turf care products. Now part of the SiteOne Landscape Supply family, the LESCO brand continues to be the go-to choice for turf professionals across the United States. LESCO fertilizers are formulated for professional applications — not diluted consumer versions. They’re used on championship golf courses, NFL stadiums, municipal parks, and high-end residential landscapes.
LESCO Fertilizer Product Lines
Granular Slow-Release Fertilizers (PolyPlus OPTI45)
LESCO’s most popular line uses PolyPlus OPTI45 controlled-release technology — a polymer-coated urea that releases nitrogen consistently over 8–12 weeks. This means less burn risk, fewer applications, and more predictable turf response. Key products include:
- LESCO 15-5-10 25% PolyPlus OPTI45 2%Fe — Balanced maintenance formula for established turf. Excellent for cool-season grasses, spring feeding programs.
- LESCO 24-5-11 50% PolyPlus OPTI45 — High-nitrogen professional formula with iron and manganese. Ideal for aggressive turf color and density programs.
- LESCO 24-0-8 30% PolyPlus OPTI45 — Zero-phosphorus maintenance fertilizer. Perfect for areas with phosphorus restrictions or established turf with adequate P levels.
- LESCO 20-2-3 22.5% Nitrate — Fast-acting nitrate nitrogen component for quick green-up alongside the slow-release fraction.
Pre-Emergent + Fertilizer Combinations
LESCO’s combination pre-emergent and fertilizer products are a favorite for spring programs because they allow you to feed the turf and prevent crabgrass in a single pass:
- LESCO Dimension 0.21% 18-0-10 — Dithiopyr pre-emergent combined with a balanced fertilizer. Controls crabgrass, annual bluegrass, and over 45 other weed species.
- LESCO Stonewall 0.43% 14-0-7 — Prodiamine-based pre-emergent plus fertilizer. Longer residual than Dimension — one application can cover the full pre-emergent window.
- LESCO Dimension 0.27G — Straight pre-emergent without fertilizer, for situations where fertility isn’t needed or has already been applied.
Herbicides and Weed Control
- LESCO Triclopyr 4 Ester — Selective broadleaf and woody plant herbicide. Excellent for spot-treating ground ivy, wild violet, and difficult broadleaf weeds in turf.
- LESCO Weed & Feed 18-2-3 — Post-emergent broadleaf weed control combined with fertilizer. Single-pass efficiency for spring and fall programs.
- LESCO Prosecutor Pro — 41% glyphosate non-selective herbicide for renovation, hardscape borders, and total vegetation control.
Fungicides and Insecticides
- LESCO T-Storm 2G — Broad-spectrum granular fungicide for brown patch, dollar spot, and other common turf diseases. Apply preventatively or curatively.
- LESCO Crosscheck Plus — Bifenthrin-based insecticide for chinch bugs, grubs, and surface-feeding pests. One of the most versatile professional insecticides available.
How to Read LESCO Fertilizer Labels
LESCO fertilizer names follow a consistent format. Understanding the naming convention helps you quickly identify the right product:
- NPK Numbers (e.g., 24-5-11): Nitrogen-Phosphorus-Potassium percentages by weight.
- % PolyPlus OPTI45: The percentage of nitrogen in controlled-release polymer-coated form. Higher = longer-lasting but slower-acting.
- %Fe, %Mn: Iron and manganese content — important for color and deficiency correction.
- SGN: Screen Grade Number — the particle size. SGN 150 = fine granule (better for residential), SGN 216 = standard fairway/sports field size.
LESCO vs. Consumer Store Brands: What’s the Difference?
Home improvement store fertilizers are typically lower analysis and diluted with fillers to reduce cost. A bag of “Scotts Turf Builder 32-0-6” sold at retail contains significantly less slow-release nitrogen than a comparable professional LESCO formula. The tradeoffs:
| LESCO Professional | Consumer Store Brand | |
|---|---|---|
| Nitrogen analysis | 15–29% | 8–32% (often inflated with fast-release) |
| Controlled release % | 25–65% PolyPlus | Variable, often 30% or less |
| Iron content | 2–5% Fe standard | Often 0% |
| Bag size | 50 lb professional bags | 12–32 lb retail bags |
| Warranty / consistency | Lot-tested, consistent analysis | Varies by season |

Frequently Asked Questions
Can I buy LESCO fertilizer without a SiteOne account?
Yes. At ProLawn Fertilizer, LESCO products are available to anyone — individual homeowners, licensed landscapers, and commercial grounds managers alike. No account required to order.
How much does a 50 lb bag of LESCO fertilizer cover?
Coverage varies by application rate. At a typical rate of 4 lb N per 1,000 sq ft (a common professional rate for a LESCO 24-5-11 formula), a 50 lb bag covers approximately 3,000–5,000 sq ft. Always calculate based on your target nitrogen rate and the specific formula’s analysis.
Is LESCO fertilizer safe for residential lawns?
Yes, but use the correct rate. LESCO products are professional formulations designed for trained applicators. Follow the label rate, water in granular products within 24 hours of application, and observe any re-entry intervals specified on the label.
