Best Fertilizer For New Grass Seed: 10 Options Compared

#1 · Best Overall

1. Scotts Turf Builder Starter Food

• Weight: 3.3 lb
• Form: Granules

Best for: Seed-time root development.

Why it ranks #1: Its 24-25-4 formula is made for new grass, sod, sprigs, and overseeding, with a stated second feeding at two to four weeks.

A 24-25-4 granular formula gives new grass a phosphorus-rich starter feeding at planting, supporting root development from the start. Scotts says it can also be used with sod, sprigs, grass plugs, or reseeding, making it a flexible choice for several lawn-establishment jobs.

Apply the granules when planting, then make a second application at two to four weeks to continue feeding as roots develop and blades emerge. The 24-25-4 analysis includes 25% phosphate, identified as fuel for root development, while the product is described as suitable for any grass type. Scotts reports thicker growth and faster development versus unfed grass, though those comparisons are relative to unfed grass, not a guaranteed result for every lawn.

Skip it if you need a product sold in Florida; this Scotts starter is explicitly not sold in that state.

Choose this for a seed-time granular feeding when you want a follow-up application during early establishment. It also suits sod and plugs, but buyers in Florida need another option, and application should follow the label directions.

#2 · Largest Coverage

2. Andersons New Lawn Starter

• Weight: 18 lb
• Form: Granules

Best for: Large-area starter feeding.

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

An 18-pound bag covers up to 5,000 square feet, giving buyers a granular starter option for larger new-turf areas. Its 20-27-5 analysis combines nitrogen and phosphorus with essential micronutrients, while added iron is intended to support deep greening.

The formula combines quick- and slow-release nitrogen, so the listing describes both immediate and sustained feeding rather than a single release pace. Its phosphorus and micronutrients are directed toward vigorous seedlings and root establishment, while 1% iron aids chlorophyll development and helps prevent yellowing. Directions say to work it two to three inches into the soil before spreading seed or laying sod, a preparation step to account for in the planting workflow.

Skip it if you want a simple apply-after-seeding routine; Greenview Starter Fertilizer 8 lb. is listed for use just before or after seeding.

Choose this for a larger lawn project where you can work fertilizer into the soil before seeding or laying sod. Its broad turf suitability and iron content suit establishment goals, but the preparation step matters.

#3 · Extended Feeding

3. Greenview Starter Fertilizer 8 lb

• Weight: 8 lb
• Form: Granules

Best for: One-time early feeding.

Why it ranks #3: This 10-18-10 formula covers 2,500 square feet and supplies immediate- and time-released nitrogen for up to eight weeks.

This 8-pound Greenview bag covers 2,500 square feet and is listed for one-time use when seeding a new lawn area. Its 10-18-10 analysis and combined immediate- and time-released nitrogen support early feeding while roots develop and take hold.

The recommended timing is just before or just after seeding, which places the application within the planting workflow rather than a later recurring schedule. Greenview says its nitrogen provides continuous feeding for up to eight weeks through immediate and controlled release. The product is intended for spring or fall establishment and bare spots, while the explicit instruction not to hand spread means buyers should plan a suitable spreading method instead.

Skip it if you need to distribute fertilizer by hand; this Greenview product explicitly says not to hand spread.

This fits spring or fall seeding and bare-spot work when a one-time application and up-to-eight-week feeding period suit the plan. It covers 2,500 square feet, but application must not be by hand.

#4 · Seeding and Sodding

4. Jonathan Green Veri-Green

• Weight: 4 lb
• Form: Granules

Best for: Seeding and sod starter.

Why it ranks #4: Its 12-18-8 formula is phosphorus-rich and intended for seeding, overseeding, and sod, with application on the day of seeding or sodding.

Jonathan Green's 12-18-8 analysis is rich in phosphorus, which the product identifies as key to root formation in new seedlings. That makes it a seeding- and sodding-focused granular option for buyers seeking early root support across lawn establishment and repair.

The directions call for applying the granules on the day of seeding or sodding with a rotary, drop, or handheld spreader. That choice of spreader types gives buyers several ways to distribute the starter, while the 12-18-8 analysis supplies the phosphorus emphasized for root formation. The product is described as helping seedlings establish faster and thicker and withstand harsh weather; those are stated benefits, not a substitute for following seeding and application directions.

Skip it if you want a liquid hose-end application; Simple Lawn Solutions Extreme Grass Growth is a ready-to-use hose-end spray.

This fits buyers establishing a lawn from seed or sod who can apply granules with a rotary, drop, or handheld spreader. Consider the spreading step and follow the application directions on seeding day.

#5

5. Jonathan Green Green-Up

• Weight: 4.5 lb
• Form: Granules

Best for: Seeding and sod nutrition.

Why it ranks #5: The 12-18-8 granular formula supports seeding, overseeding, and sodding, and its listed compatibility includes several cool- and warm-season grasses.

Jonathan Green's 12-18-8 Green-Up formula emphasizes phosphorus for developing deep, dense roots, targeting new grass from seed or sod. Its listed uses also include overseeding, giving buyers a single granular lawn food for several establishment and repair situations.

The product is described as helping seedlings grow faster and thicker while supplying nutrients for growth, with phosphorus identified as important to root formation. The 12-18-8 analysis makes that root-focused emphasis concrete, and the listed seeding, overseeding, and sodding uses broaden its role beyond a new lawn from scratch. Its safety information names several cool- and warm-season grasses, so buyers can check the supplied grass list against their lawn before application.

Skip it if you need a stated coverage area to plan a large lawn; The Andersons Premium New Lawn Starter lists coverage up to 5,000 square feet.

Choose this for seed, overseeding, or sod when its 12-18-8 formula and listed grass types fit your lawn. Check the product directions and grass guidance, especially if coverage planning is central to your purchase.

#6

6. GreenView Solutions Starter

• Weight: 16 lb
• Form: Granules

Best for: Bare-spot repair feeding.

Why it ranks #6: This 10-18-10 starter feeds for up to eight weeks and is intended for new lawns or bare spots, with a 16-pound bag.

GreenView's 10-18-10 starter is specified for newly seeded lawns and bare spots, so one formula addresses both fresh establishment and patch repair. Its phosphorus-focused root support and slow-release feeding are intended to help new grass develop without micro-plastic coatings.

The product description says it feeds for up to eight weeks, pairing longer-lasting nutrition with its stated aim of speeding root development. Its 10-18-10 analysis provides the listed nitrogen, phosphorus, and potassium, while the no-micro-plastic-coating claim may matter to buyers seeking to avoid plastic residue from slow-release fertilizer coatings. Directions outline a sequence: clear debris, apply seed, spread fertilizer, and water.

Skip it if you do not want to water after spreading fertilizer; the listed directions make watering the final application step.

Pick this for seeding or repairing bare spots when an eight-week feeding period and uncoated slow-release formula fit your priorities. Plan to clear the area, seed, apply fertilizer, and water as directed.

#7

7. Fertilome New Lawn Starter

• Weight: 20 lb
• Form: Granules

Best for: Broad-spreader lawn projects.

Why it ranks #7: The 9-13-7 granular fertilizer can be applied with seed or immediately after, and the 20-pound bag covers up to 5,000 square feet.

A 20-pound bag covers up to 5,000 square feet, making this granular 9-13-7 starter suited to larger seed or sod projects. Fertilome describes its role as supporting root and mature-stem development before rapid growth begins, with application by drop or broadcast spreader.

The stated application rate is four pounds per 1,000 square feet, so the coverage figure gives buyers a planning reference for distributing the bag across a lawn. The 9-13-7 analysis supplies nitrogen, phosphate, and soluble potash, while the product is intended to support seed and sod establishment. Directions emphasize even, uniform spreading and warn against streaks, skips, or overlaps, making spreader technique part of the application workflow.

Skip it if you do not have a drop or broadcast spreader; Greenview Starter Fertilizer 8 lb. is another listed option, though it also cannot be hand spread.

This suits buyers with a drop or broadcast spreader who are establishing seed or sod across a larger area. Use the stated rate and distribute evenly; the spreader requirement makes it less suitable for hand application.

#8 · Fast Liquid Application

8. Scotts Liquid Starter Lawn Food

• Weight: 8.32 oz
• Form: Liquid

Best for: Quick hose-end application.

Why it ranks #8: The 7-12-15 ready-to-spray liquid offers up to three 600-square-foot feedings; directions call for weekly application after seedlings sprout.

A reusable spray applicator lets this liquid starter connect to a garden hose, turning application into a short spray-and-water workflow. The 32-ounce bottle provides up to three feedings of 600 square feet each, making measured small-area coverage straightforward for new-lawn care.

Scotts lists a 7-12-15 NPK formula, with phosphorus supporting early growth and root development. The translucent bottle helps users see how much product they are using, and the reusable applicator avoids replacing the spray attachment when using separately sold refill bottles. Directions specify applying once weekly for three weeks just after seedlings sprout, so this is a post-emergence routine rather than a single application at planting.

Skip it if you prefer one application at seeding; Greenview Starter Fertilizer 8 lb. is listed for one-time use just before or after seeding.

This suits buyers who prefer hose-end liquid feeding and can return weekly after seedlings sprout. Its visible bottle and reusable applicator support the workflow, but the three-week schedule differs from a single planting-time application.

#9

9. Simple Lawn Solutions Growth Booster

• Weight: 2 lb
• Form: Liquid

Best for: Hose-end growth application.

Why it ranks #9: The hose-end liquid is described for new seeding and sod, but its listing emphasizes growth boosting rather than a defined starter NPK ratio.

A ready-to-use hose-end sprayer lets Simple Lawn Solutions apply its liquid fertilizer evenly across a prepared lawn without a separate spreader step. The humic-acid formula is presented for vertical and lateral growth, including new seeding, sod, nutrient deficiency, and lawn repair.

The directions start with preparing the area for seed or sod, then connecting the bottle to a hose and spraying evenly. That workflow makes the hose connection central to application, while the concentrated nitrogen and phosphorus formula is described as a growth booster. The listing names many grass types, including Bermuda, St. Augustine, Zoysia, fescue, ryegrass, and Kentucky bluegrass, giving buyers a broad stated compatibility list to consult.

Skip it if you cannot connect a garden hose where you need to spray; Scotts Turf Builder Starter Food is a granular alternative for planting or reseeding.

This suits buyers who want hose-end liquid application for new seed, sod, or repair and whose grass appears on the listed types. A hose connection and even spraying are integral to the stated directions.

#10

10. Scotts Triple Action Built for Seeding

• Weight: 4.3 lb
• Form: Granules

Best for: Seed-time weed prevention.

Why it ranks #10: It is intended for planting new grass and prevents dandelion and crabgrass for up to six weeks, but its added weed-control function makes it less focused on feeding alone.

Scotts combines new-grass fertilizer with prevention of dandelion and crabgrass for up to six weeks, addressing weed pressure alongside establishment. The granular formula is specifically intended for planting new grass and is listed for several turf types, including Kentucky bluegrass and tall fescue.

The product is intended to jump-start grass development and strengthen new grass while preventing the named weeds without harming new grass, when used as directed. Application has a defined window: spread on a dry lawn when temperatures are consistently between 60°F and 90°F. That temperature and surface condition make timing important, and the listed grass types provide a useful boundary for checking whether the formula matches the planned lawn.

Skip it if you cannot apply on a dry lawn within the stated 60°F-to-90°F temperature range; Scotts Turf Builder Starter Food has no such timing condition listed.

Choose this when you want seed-time feeding combined with prevention of dandelion and crabgrass. Its application window is specific, and the supplied grass-type list should match your lawn before you apply.
