Best Starter Fertilizer For New Grass: 10 Options Compared

#1 · Best Overall

1. Scotts Turf Builder Starter Food

• Weight: 3.3 lb
• Form: Granules

Best for: Seed, sod, and plug starters.

Why it ranks #1: Its 24-25-4 formula suits new grass, sod, plugs, and reseeding; directions specify application at planting and again after two to four weeks.

A 24-25-4 granular formula gives Scotts Turf Builder Starter Food a clear role at planting, where its 25% phosphate supports root development from the start. It is made for seed, sod, sprigs, and plugs, so it suits homeowners establishing a lawn or filling in an existing one.

Apply the granules when planting, then make a second application after 2–4 weeks to continue feeding as roots and blades develop. That two-step schedule is useful when you want nutrition to continue through early establishment, rather than relying on a single application. Scotts says the formula is suitable for any grass type and for new lawns, sod, plugs, or reseeding. Its stated comparison is versus unfed grass: 70% thicker and 35% quicker growth.

Skip it if you want a ready-to-spray application; Scotts Turf Builder Liquid Starter Lawn Food connects to a garden hose.

Choose it if you want granular starter nutrition for seed, sod, sprigs, or plugs and can return for the 2–4-week follow-up. The formula is not sold in Florida, so that regional restriction matters.

#2 · Best Sustained Feed

2. Andersons New Lawn Starter

• Weight: 18 lb
• Form: Granules

Best for: Extended feeding and deep greening.

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

Three nitrogen release speeds—fast, intermediate, and slow—give The Andersons Premium New Lawn Starter both an immediate and sustained feeding approach. Its 20-27-5 formula also includes 1% iron, making it a fit for new turf where root establishment and deeper green color are priorities.

This 18-pound granular fertilizer covers up to 5,000 square feet and is suitable for all turf types, including northern and southern grasses. Work it into soil 2–3 inches deep before spreading seed or laying sod, so application is tied to site preparation rather than a later spray routine. The quick- and slow-release nitrogen supports feeding over time, while the iron aids chlorophyll development and helps prevent yellowing.

Skip it if you need to top-dress after seeding instead of working fertilizer into prepared soil; Scotts Turf Builder Liquid Starter Lawn Food is applied after sprouting.

Consider it for a larger establishment project when you can incorporate fertilizer during soil preparation and want staged nitrogen plus iron. Its stated coverage is 5,000 square feet, so plan around that area.

#3 · Best Eight-Week Feed

3. Greenview Starter Fertilizer

• Weight: 8 lb
• Form: Granules

Best for: One-time seeding applications.

Why it ranks #3: Its 10-18-10 formula provides immediate and time-released nitrogen for up to eight weeks, with a stated 2,500-square-foot coverage.

Immediate- and time-released nitrogen feed for up to eight weeks gives Greenview Starter Fertilizer a one-application approach to early lawn establishment. The 10-18-10 granules are intended for use just before or just after seeding, making them relevant for new lawns and bare spots.

The 8-pound bag covers 2,500 square feet, giving buyers a defined area for planning a seeding project. Apply it as the last step before or just after seeding; the product is described as a one-time use for a new lawn area. Its combination of readily available and controlled-release nitrogen supports continued feeding while roots develop and take hold, without requiring the listed weekly schedule of a liquid starter.

Skip it if you need a recurring weekly post-sprout routine; Scotts Turf Builder Liquid Starter Lawn Food lists three weekly applications.

It fits a seeding project where you want granular fertilizer applied as a final preparation step and feeding to continue for up to eight weeks. Its 2,500-square-foot coverage is the relevant area boundary.

Listed on Amazon as: Greenview Starter Fertilizer 8 lb. Bag, Covers 2,500 sq. ft.

#4 · Best Large Coverage

4. Jonathan Green New Lawn Starter

• Form: Granules

Best for: Large lawns and seasonal seeding.

Why it ranks #4: The 12-18-8 granular formula is intended for seed, sod, and lawn repair, and its 45-pound bag covers up to 15,000 square feet.

Coverage up to 15,000 square feet makes Jonathan Green 12-18-8 New Lawn Starter a large-area granular option for seeding, sodding, and lawn repair. Its high-phosphorus formula is aimed at root development, with listed use across summer and fall applications.

The stated application rate is four pounds per 1,000 square feet, letting buyers calculate the amount for a project up to the listed 15,000-square-foot coverage. The granular form suits spreading across larger seeded or sodded areas, while the listed seasonal versatility includes summer and fall. Its 12-18-8 formula supplies high phosphorus for root establishment, and the product is specified for all grass types, broadening its fit for mixed lawn projects.

Skip it if you are treating a small patch and want a smaller coverage amount; Ferti-lome New Lawn Starter covers up to 1,000 square feet.

This fits large lawn establishment or repair where a measured granular rate and broad seasonal use are helpful. Its 15,000-square-foot coverage and 45-pound size are less convenient for isolated small patches.

#5 · Best No-Microplastic

5. Greenview Solutions Starter

• Weight: 16 lb
• Form: Granules

Best for: Bare-spot and seasonal repairs.

Why it ranks #5: This 10-18-10 formula is designed for new lawns and bare spots, feeds for up to eight weeks, and specifies no micro-plastic coatings.

A slow-release formula without micro-plastic coatings is the defining feature of GreenView Solutions Starter Fertilizer. Its 10-18-10 granules are positioned for new seeding and bare-spot repair anytime during the growing season, combining root support with feeding that lasts up to eight weeks.

For application, clear debris, spread the grass seed of your choice, apply the fertilizer, and water. That sequence makes it straightforward to include in a repair workflow without specifying a particular seed type. The phosphorus-focused formula supports root establishment, while the stated slow-release feeding lasts up to eight weeks. The no-micro-plastic-coatings feature may matter to buyers seeking a slow-release product that leaves no plastic coating residue in the lawn.

Skip it if you want a hose-end liquid application instead of granules; Scotts Turf Builder Liquid Starter Lawn Food uses a reusable spray applicator.

Choose it for seeding or repairing bare spots when slow-release feeding and no micro-plastic coatings matter. The listed workflow ends with watering, so it fits buyers able to follow that application step.

#6

6. Fertilome New Lawn Starter

• Weight: 4 lb
• Form: Granules

Best for: Small lawns and sod establishment.

Why it ranks #6: The 9-13-7 formula is made for seed and sod root development, and the four-pound bag covers up to 1,000 square feet.

A four-pound bag covers up to 1,000 square feet, giving Ferti-lome New Lawn Starter a defined fit for smaller seeding or sod projects. Its 9-13-7 formula is intended to help grass develop roots and mature stems before rapid growth begins.

Apply the granules evenly with a drop or broadcast spreader, at the listed rate of four pounds per 1,000 square feet. The even-spreading direction matters for buyers seeking to avoid streaks and skips across a small lawn. Ferti-lome can be applied with grass seed or immediately after seeding, and the supplied facts also note that it helps sod establish. Its nutrient mix includes 13% phosphate and 7% soluble potash.

Skip it if you need coverage for a larger project; The Andersons Premium New Lawn Starter covers up to 5,000 square feet.

This is a practical match for a small lawn, seeding patch, or sod area when you have a drop or broadcast spreader. Its 1,000-square-foot coverage makes it less suited to larger areas.

#7

7. CountryMax Fas-Start

• Weight: 15 lb
• Form: Granules

Best for: Seed, sod, and overseeding projects.

Why it ranks #7: Its 18-24-12 seed-starter formula is listed for new seed, sod, and overseeding, with a stated coverage of 5,000 square feet.

The 18-24-12 formula pairs high phosphorus and potash with nitrogen for CountryMax Fas-Start Seed Starter Fertilizer. It is specified for new grass seed, sod, and overseeding, giving lawn owners one granular option across several establishment and repair workflows.

The 15-pound bag covers 5,000 square feet, a stated area that can help buyers map it to a larger lawn project. Its phosphorus and potash levels support deeper, stronger roots, while nitrogen promotes greener color and fuller development. The product also identifies essential nutrients often missing in new lawn areas. Those features make it relevant both when establishing turf and when overseeding, without requiring a separate product for those listed uses.

Skip it if you need a clearly stated application rate and spreader method; Ferti-lome New Lawn Starter lists both a rate and drop or broadcast spreader use.

It suits buyers covering up to 5,000 square feet across seeding, sod, or overseeding and who value root support alongside greener growth. The supplied listing leaves application rate and equipment unspecified.

#8

8. Scotts Liquid Starter Lawn Food

• Weight: 8.32 oz
• Form: Liquid

Best for: Quick hose-end applications.

Why it ranks #8: The 7-12-15 liquid formula uses a reusable hose applicator, covers up to three 600-square-foot feedings, and is directed weekly after sprouting.

A reusable hose-connected applicator lets Scotts Turf Builder Liquid Starter Lawn Food cover up to 600 square feet in a 10-minute feeding. The translucent 32-ounce bottle also shows how much liquid remains, making this a practical option for people who prefer visible, quick lawn applications.

The 7-12-15 liquid formula is phosphorus-rich, supporting early growth and root development after seedlings have sprouted. Connect the applicator to a garden hose and spray; the listed directions call for one application each week for three weeks after sprouting. The bottle provides up to three separate 600-square-foot feedings, and its reusable applicator works with separately sold refill bottles, a useful workflow for repeat applications.

Skip it if you want a single granular application at seeding; Greenview Starter Fertilizer 2129859 is listed for one-time use.

It suits a new-lawn owner who values hose-end speed, visible liquid level, and scheduled post-sprout feeding. Account for three weekly applications and the fact that refill bottles are sold separately.

#9

9. Neptune’s Harvest Lawn Starter

• Weight: 9 lb
• Form: Liquid

Best for: Fish-and-seaweed liquid starter.

Why it ranks #9: This 2-3-2 liquid starter uses fish and seaweed and is described for new lawns, though supplied details omit an application rate and coverage.

Fish and seaweed form the base of Neptune’s Harvest Lawn Starter Fertilizer, a liquid 2-3-2 product for new lawns. Its description highlights natural micronutrients and minerals alongside phosphorus, connecting the formula to root density, soil quality, and grass color.

The liquid form distinguishes this gallon product from the listed granular starters, while the 2-3-2 analysis provides a defined nutrient ratio. The fish-and-seaweed base supplies natural micronutrients and minerals, and the product is presented for newly seeded lawns to support root development and vibrant growth. The supplied claims also describe it as safe for kids and pets; follow the label and keep the product out of reach of children and pets as directed.

Skip it if you need a listed coverage rate and application schedule; Jonathan Green 12-18-8 specifies both area coverage and rate.

It suits buyers seeking a fish-and-seaweed liquid starter for newly seeded lawns and valuing the listed micronutrient and root-development focus. Coverage, dilution, and application frequency are not supplied, limiting planning detail.

#10

10. Scotts 2708 Starter Fertilizer

• Weight: 4 lb
• Form: Granules

Best for: Time-release feeding across grass types.

Why it ranks #10: It is described for establishing grass and any grass type, but the supplied details give no NPK ratio, application rate, or coverage figure.

Patented time-release nitrogen is the central feature of Scotts Company 2708 Starter Fertilizer, feeding new lawns during development without burning, according to its description. It is also listed for any grass type and is presented as a way to reduce water requirements.

This granular starter is intended for establishing grass and can be used with any grass type, so the listing does not restrict buyers to a particular turf variety. Its time-release nitrogen provides feeding during development, rather than only an immediate nutrient release. The product description also connects its use with efficiently reducing water requirements. The supplied information identifies a 4-pound item but does not give a coverage figure or a detailed application schedule.

Skip it if you need a stated area coverage and application rate; Ferti-lome New Lawn Starter lists coverage and a per-area rate.

Consider it if time-release feeding and the listed water-reduction benefit are priorities across grass types. The available product details do not provide coverage or an application schedule, so those planning specifics remain unclear.
