The best lawn fertilizers ranked by lawn care professionals. Slow-release nitrogen, organic options, winterizer, and starter products matched to your grass type and season.
Lesco 24-0-11 is the best overall lawn fertilizer for spring and fall maintenance. Professional-grade, 50% slow-release, won't burn at labeled rates. For organic, Milorganite is impossible to burn and adds iron for color. For the winterizer application, straight 46-0-0 urea outperforms everything else.
The professional standard. 24% nitrogen with half slow-release feeds for 6 to 8 weeks per application. Potassium for stress tolerance. Available at SiteOne Landscape Supply. This is what most lawn care companies use and what we use on our own properties. Apply at 4 lbs per 1,000 sq ft for 1 lb nitrogen.
Slow-release organic nitrogen from heat-dried biosolids. Cannot burn even if over-applied. Contains iron for dark green color without synthetic chemicals. The safest fertilizer for DIY homeowners who worry about burning. Apply at 16 lbs per 1,000 sq ft. Available everywhere.
Pure fast-release nitrogen for the late-fall winterizer application on cool-season lawns. Apply 1 to 1.5 lbs N per 1,000 sq ft (2.2 to 3.3 lbs product) in late October to November. This single application drives root energy storage and the best spring green-up of any product. Not for summer use (burn risk).
The most widely available consumer fertilizer. Contains a mix of slow and quick-release nitrogen. Feeds for 6 to 8 weeks. Available at every hardware store and big box retailer. Not as high in slow-release as Lesco but perfectly adequate for homeowners who want convenience. WaterSmart technology reduces burn risk.
High-phosphorus formula specifically for new grass seed. Phosphorus drives root development in seedlings. Apply at the bag rate when seeding or sodding. NOT for established lawns (most soils don't need extra phosphorus). Some states restrict phosphorus use: check local regulations before purchasing.
We evaluated fertilizers based on nitrogen content, slow-release percentage, burn risk, secondary nutrient value (iron, potassium), cost per application, and real-world performance on lawns we manage. We test these products on client lawns every season. None of these recommendations are sponsored.
Ranked by nitrogen percentage, slow-release percentage, burn risk, secondary nutrients, cost per 1,000 sq ft per application, and real-world results on cool-season and warm-season lawns in the Central Plains. Applied and evaluated by lawn care professionals with 30+ years of experience. Prices checked April 2026.
Lesco 24-0-11 for professional-quality results. Milorganite 6-4-0 for organic and zero burn risk. Scotts Turf Builder for consumer convenience. The best fertilizer is the one matched to your grass type and applied at the right time, not the most expensive brand.
Different strengths. Milorganite is organic, impossible to burn, and contains iron for color. Scotts has higher nitrogen content and feeds faster. Milorganite is better for summer when burn risk is high. Scotts is better for spring and fall when you want visible response. Many lawn enthusiasts use both in different seasons.
Milorganite is the most popular and widely available organic lawn fertilizer. Apply at 16 lbs per 1,000 sq ft, 3 to 4 times per year. It contains iron for dark green color and cannot burn. Corn gluten meal is another organic option that doubles as a mild pre-emergent.
Professional grade (Lesco): about $4 per 1,000 sq ft per application. Consumer grade (Scotts): about $2.50 per 1,000 sq ft. Organic (Milorganite): about $8 per 1,000 sq ft. A typical lawn needs 3 to 5 applications per year, so annual fertilizer cost is $10 to $40 per 1,000 sq ft.
