Best Fertilizer For New Lawns for Seed, Sod, and Bare Spots

#1 · Best Overall

1. Scotts Turf Builder Starter Food

• Weight: 42 lb
• Form: Granules

Best for: Large new lawn from seed or sod.

Why it ranks #1: Its 24-25-4 formula is specified for new grass, sod, and plugs, and the 42-pound bag covers 14,000 square feet.

The 24-25-4 granular formula is the defining feature here: its phosphorus-rich balance supports root development while feeding newly planted grass. Scotts says it can grow new grass 70% thicker and 35% quicker versus unfed grass, and the formula also suits sod and grass plugs across all grass types.

Apply with a spreader at planting, then make a second application at two to four weeks to sustain nutrition as roots and blades develop. That staged schedule gives new lawns continued feeding during early establishment rather than relying on one application. The 42-pound bag covers 14,000 square feet, making it a practical option for a broad seeding or sodding project. Daily watering to keep the soil surface moist is part of the listed care directions.

Skip it if you want a hose-connected application; Scotts Turf Builder Liquid Starter Lawn Food applies through its reusable spray applicator.

Choose this granular starter for a large lawn project involving seed, sod, or plugs, especially if you can follow its repeat-feeding schedule. It requires spreader application and daily watering to keep the soil surface moist.

#2 · Multi-Release Nitrogen

2. Andersons New Lawn Starter

• Weight: 18 lb
• Form: Granules

Best for: Pre-plant soil preparation.

Why it ranks #2: The 20-27-5 formula combines quick- and slow-release nitrogen, includes 1% iron, and covers up to 5,000 square feet.

Work this 20-27-5 granular starter two to three inches into the soil before spreading seed or laying sod, a defining step for buyers preparing a new lawn bed. Its quick- and slow-release nitrogen combines immediate and sustained feeding, while 1% iron supports deeper greening.

The pre-plant incorporation instructions make this fertilizer a natural fit for projects where soil preparation is already underway. Three nitrogen release speeds—fast, intermediate, and slow—provide feeding across different timings, while phosphorus and potassium support the starter formula’s establishment role. It is listed as safe for northern and southern turf types and for spring or fall applications. The 18-pound bag covers up to 5,000 square feet, helping buyers size a project before spreading.

Skip it if you have already seeded and want a post-seeding application; ferti-lome New Lawn Starter can be applied with seed or immediately after.

This is a strong fit for a lawn installation where you can incorporate fertilizer during soil preparation. Consider the pre-seeding step and 5,000-square-foot coverage when planning the work and bag quantity.

#3 · Bare-Spot Repair

3. GreenView Solutions Starter

• Weight: 16 lb
• Form: Granules

Best for: Bare-spot and seasonal seeding.

Why it ranks #3: This 10-18-10 granular starter is specified for new lawns and bare spots, feeds for up to eight weeks, and has no micro-plastic coatings.

GreenView’s no-micro-plastic-coating formula distinguishes this starter for buyers who want slow-release feeding without plastic residue left in the lawn. Its 10-18-10 analysis supports root establishment, and the product is intended for new seeding or bare-spot repair throughout the growing season.

Apply it after clearing debris and applying the grass seed of your choice, then water; that sequence fits both full-lawn seeding and spot repair. The phosphorus-containing 10-18-10 formula is described as helping roots establish quickly and grow deep and strong. GreenView states that the fertilizer feeds for up to eight weeks, so the slow-release format extends nutrition beyond the initial application. The 16-pound granular bag offers more product than the brand’s listed eight-pound starter bag.

Skip it if you need a stated coverage figure to plan a measured application; Greenview Starter Fertilizer 8 lb. covers 2,500 square feet.

This is a fit for seeding or repairing bare spots when a no-micro-plastic-coating formula and up-to-eight-week feeding matter. Check project needs against the listed application directions, which do not state coverage.

#4 · Seed and Sod

4. Jonathan Green Veri-Green

• Weight: 4 lb
• Form: Granules

Best for: Seed-and-sod establishment granules.

Why it ranks #4: Its 12-18-8 phosphorus-rich formula is designed for seeding, overseeding, and sod, with directions to apply on seeding or sodding day.

A 12-18-8 analysis gives this granular starter its root-focused edge for seeding and sodding. Jonathan Green identifies phosphorus as a key component in root formation, making this a fit for buyers who want one fertilizer for new seedlings, overseeding, or newly laid sod.

Apply with a rotary, drop, or handheld spreader on the day you seed or lay sod, so the fertilizer fits directly into the establishment workflow. Its phosphorus-rich 12-18-8 formula supports root development, while the product description also connects feeding with faster, thicker growth. The 1,500-square-foot coverage makes the intended project scale clear for planning. It is a granular product, so application involves a spreader rather than a hose-connected spray routine.

Skip it if you need coverage beyond 1,500 square feet in one bag; Scotts Turf Builder Starter Food covers 14,000 square feet.

Choose this for a modest seeding, overseeding, or sod project where you want a phosphorus-rich granular starter. Its 1,500-square-foot coverage is the key boundary when estimating how much lawn one bag serves.

#5 · Large Bag Format

5. Lawn Synergy Starter Fertilizer

• Weight: 50 lb
• Form: Granules

Best for: Bulk starter for lawn renovation.

Why it ranks #5: The 15-20-10 starter comes in a 50-pound bag and directs application at 5 pounds per 1,000 square feet for seed or sod.

The 50-pound bag and 15-20-10 high-phosphorus formula make this Lawn Synergy starter suited to larger new or renovated lawns. It is presented for seed, sod, overseeding, and stressed-lawn repair, with the phosphorus balance supporting root development and early establishment.

The listed application rate is five pounds per 1,000 square feet, giving buyers a straightforward basis for calculating product needs across a renovation. Its 15-20-10 analysis emphasizes phosphorus for early root growth, while slow-release nitrogen supports gradual nutritional uptake. The product information states plant response for up to 10 weeks for the slow-release fertilizer. As granules, it fits a spread-and-water lawn workflow, though the supplied directions do not specify an application tool.

Skip it if you are treating only a small bare patch and want a smaller bag; Greenview Starter Fertilizer comes in an eight-pound bag.

Consider this bulk granular option for a new lawn or renovation where seed, sod, or repair work covers substantial area. Calculate needs at five pounds per 1,000 square feet before starting.

#6

6. Fertilome New Lawn Starter

• Weight: 20 lb
• Form: Granules

Best for: Seed-and-sod spreader application.

Why it ranks #6: Its 9-13-7 formula is designed for seed and sod, and the 20-pound bag covers up to 5,000 square feet at 4 pounds per 1,000.

Ferti-lome’s 9-13-7 formula is intended to help seed and sod develop roots and mature stems before rapid growth begins. The 20-pound bag covers up to 5,000 square feet, giving buyers a clear project scale for new lawn establishment.

Apply four pounds per 1,000 square feet with a drop or broadcast spreader, either with grass seed or immediately after seeding. That timing lets the fertilizer fit into the planting workflow, while the stated formula supplies nitrogen, phosphate, and soluble potash. Even, uniform spreading helps avoid streaks, skips, and overlaps, so careful coverage matters across the lawn. Its stated use for sod establishment also makes it an option when laying turf rather than starting from seed.

Skip it if you want a high-phosphorus 20-27-5 formula for pre-plant soil incorporation; The Andersons Premium New Lawn Starter offers that approach.

This suits buyers establishing seed or sod who want a spreader-applied granular fertilizer with defined coverage and rate. Plan for uniform application, and note that the formula is 9-13-7 rather than a higher-phosphorus blend.

#7

7. Greenview Starter Fertilizer

• Weight: 8 lb
• Form: Granules

Best for: One-time feeding for small lawns.

Why it ranks #7: The 10-18-10 formula provides immediate- and time-released nitrogen for up to eight weeks; this 8-pound bag covers 2,500 square feet.

The eight-pound bag covers 2,500 square feet and is intended for one-time use in spring or fall, making this Greenview starter easy to size for a smaller new lawn. Its 10-18-10 formula targets root growth and nutrient absorption as seedlings establish.

Apply just before or just after seeding, using this as the last step in the seeding process. Immediate-release and time-released nitrogen provide continuous feeding for up to eight weeks, so a single application covers the early growth period described by the product. The one-time seasonal-use guidance makes the schedule simple for a focused lawn project. It is a granular fertilizer, and the safety information says not to spread it by hand.

Skip it if you need a 16-pound bag for a larger project; GreenView Solutions Starter Fertilizer is supplied in that size.

Choose this for a smaller spring or fall seeding area that fits the 2,500-square-foot coverage and calls for one-time feeding. Use an appropriate spreader, since hand spreading is specifically discouraged.

#8

8. Scotts Triple Action Built for Seeding

• Weight: 4.3 lb
• Form: Granules

Best for: New grass with weed prevention.

Why it ranks #8: Designed for planting new grass, it feeds and strengthens seedlings while preventing dandelion and crabgrass for up to six weeks when used as directed.

Its triple-action formula pairs new-grass feeding with prevention of dandelion and crabgrass for up to six weeks, making this Scotts product distinct from a starter that only supplies nutrients. It is intended for use when planting new grass and is listed for several named turf types.

Apply the granules to a dry lawn when temperatures are consistently between 60°F and 90°F, following the specified weather and surface conditions. The formula is described as jump-starting grass development and strengthening new grass while preventing dandelion and crabgrass for up to six weeks without harming new grass. It is listed for Kentucky bluegrass, tall fescue, perennial ryegrass, centipedegrass, and fine fescue. Those conditions and turf types make timing and grass selection important.

Skip it if you need a starter for grass types beyond those listed; Scotts Turf Builder Starter Food is stated for all grass types.

Choose this when establishing one of its listed grass types and you want feeding combined with dandelion and crabgrass prevention. Apply only within the stated dry-lawn and 60°F-to-90°F conditions.

#9

9. Scotts Liquid Starter Lawn Food

• Weight: 8.32 oz
• Form: Liquid

Best for: Fast hose-applied starter feeding.

Why it ranks #9: The 7-12-15 liquid formula is designed for new grass and its reusable hose applicator provides up to three 600-square-foot feedings.

A reusable hose-connected spray applicator makes this liquid starter a quick way to feed a newly sprouted lawn: the listed application takes 10 minutes. The translucent bottle lets you monitor how much product remains, while the 7-12-15 formula supplies phosphorus for early growth and root development.

Connect the applicator to a garden hose, turn on the water, and spray; the bottle provides up to three separate 600-square-foot feedings. This workflow avoids spreading granules, and the transparent container helps you see product use as you work. The directions call for an application once weekly for three weeks, beginning just after seedlings sprout. Its reusable applicator can be paired with refill bottles sold separately, and the liquid is suitable for any grass type.

Skip it if you prefer granular feeding before seed or sod goes down; The Andersons Premium New Lawn Starter is worked into soil beforehand.

This suits homeowners who want a fast hose-and-spray routine for newly sprouted grass and can repeat feeding weekly for three weeks. Its listed directions start after seedlings emerge, rather than at planting.

#10

10. Jonathan Green Green-Up

• Weight: 4.5 lb
• Form: Granules

Best for: Compact seeding and sodding projects.

Why it ranks #10: This 12-18-8 fertilizer is specified for seeding, overseeding, and sod, but its listed 1,500-square-foot coverage is smaller than several alternatives.

Jonathan Green’s 12-18-8 phosphorus-rich formula focuses this 1,500-square-foot starter on root formation for new seedlings. It is listed for seeding, overseeding, and sod, giving smaller establishment or renovation projects one granular fertilizer for several common starting methods.

The 12-18-8 analysis supports root development, while the product description says it helps new grass grow faster and thicker. It can be used on the listed cool-season grasses, including Kentucky bluegrass, tall fescue, and ryegrass, as well as warm-season lawns referenced in the product information. The 1,500-square-foot coverage helps set a clear project limit. This is granular fertilizer, so buyers should plan for a spreader-based application rather than the liquid spray workflow of a hose-connected product.

Skip it if your project exceeds 1,500 square feet and you want broader coverage; Scotts Turf Builder Starter Food covers 14,000 square feet.

This compact option fits a smaller seed, overseeding, or sod project where phosphorus-focused root support is the priority. Check the 1,500-square-foot coverage against your lawn area before choosing it.
