A strong fall starter fertilizer supplies nutrients that support root establishment, suits seeding or overseeding, and matches the area you need to cover. The Andersons Premium New Lawn Starter is a particularly clear fit because its listing names fall applications and gives a 20-27-5 analysis, while Greenview Solutions Starter Fertilizer is designed for new lawns and bare spots throughout the growing season. This comparison also includes several 12-18-8 options from Jonathan Green, a compact Scotts starter, and products with differing coverage information.
Check local rules before applying phosphorus-containing lawn fertilizer: some places restrict its use. Follow each product’s label for application rate and timing, and keep newly seeded soil moist as directed.
The best choice depends on fall suitability, nutrient balance, package coverage, and the size of your seeding project.
The Andersons Premium New Lawn Starter leads for fall seeding because its product information explicitly identifies spring and fall applications, specifies a 20-27-5 formula, and says it covers up to 5,000 square feet. It also combines quick- and slow-release nitrogen with micronutrients and 1% iron. Greenview Solutions Starter Fertilizer is a strong alternative for seeding or bare-spot repair across the growing season, with a 10-18-10 formula and feeding for up to eight weeks.

Detailed Reviews: Best Fertilizer For New Grass Seed In Fall
#1 · Best Overall
1. The Andersons New Lawn Starter
- Weight: 18 lb
- Form: Granules
Best for: Pre-seed soil preparation.
Why it ranks #1: Its listing specifically names fall applications, provides a 20-27-5 analysis, and covers up to 5,000 square feet with quick- and slow-release nitrogen.
Three nitrogen release types—fast, intermediate, and slow—give The Andersons New Lawn Starter both an initial feed and continued nutrient supply. Its 20-27-5 formula also provides substantial phosphorus for root establishment, making it a fit for fall projects where fertilizer can be worked into soil before seeding.
The application directions call for working the granules two to three inches into soil before spreading seed or laying sod. That makes this a better match for planned lawn installation than a quick surface application after sowing. Fast, intermediate, and slow-release nitrogen support feeding across different stages, while phosphorus targets root development. The formula is safe for northern and southern turf types, and 1% iron aids chlorophyll development and deep greening.
- 20-27-5 formula includes 27% phosphorus
- Fast, intermediate, and slow-release nitrogen
- Safe for northern and southern turf types
- 1% iron aids chlorophyll development and greening
- Directions require working fertilizer into soil two to three inches before seeding or sod installation.
Skip it if you have already spread seed and need a fertilizer applied afterward; the listed directions require incorporating this into soil first.
Pick The Andersons for a fall lawn project where soil preparation comes before seed or sod and staged nitrogen feeding is useful. Its pre-plant incorporation step is a poor fit for a finished seeding pass.

2. Greenview Solutions Starter Fertilizer
- Weight: 16 lb
- Form: Granules
Best for: Root-focused fall seeding.
Why it ranks #2: Made for new lawns and bare-spot repair during the growing season, its 10-18-10 formula supports root growth and feeds for up to eight weeks.
An 10-18-10 analysis with phosphorus at 18% puts root development at the center of GreenView’s starter formula. That focus suits fall seeding and bare-spot repairs, when newly emerging grass needs to establish roots. Its slow-release feeding lasts up to eight weeks, extending nutrient support beyond the initial application.
Use it when seeding a new lawn or repairing bare spots during the growing season. The directions put seed down before fertilizer, followed by watering, so it fits a straightforward seed-first workflow. Phosphorus supports quick, deep root growth, while the slow-release formula feeds for up to eight weeks. GreenView also specifies no micro-plastic coatings, an advantage for buyers seeking slow-release feeding without plastic residue left behind in the lawn.
- 10-18-10 formula supplies phosphorus for root establishment
- For new lawns and bare-spot repair
- Feeds for up to eight weeks
- Slow-release formula has no micro-plastic coatings
- Feeding lasts up to eight weeks, so it does not provide longer-duration support.
Skip it if you need feeding beyond eight weeks from one application; this formula’s stated feeding period is limited to that span.
Choose GreenView for fall seeding or patching when root establishment and an eight-week feed are priorities. It fits a seed-first, water-after application routine, but buyers seeking longer feeding from a single application should look elsewhere.

3. Jonathan Green Green-Up 5,000
- Weight: 15.2 lb
- Form: Granules
Best for: Large seeding and sodding areas.
Why it ranks #3: Designed for seeding, overseeding, and sod, this 12-18-8 granule package covers 5,000 square feet and supports root development.
A stated 5,000-square-foot coverage area makes Jonathan Green Green-Up Lawn Food a practical choice for treating a broad new lawn in one seeding or sodding project. Its 12-18-8 analysis is rich in phosphorus, which supports root formation as seedlings establish through fall.
This granule formula is intended for seeding, overseeding, and sod, so it can serve across several establishment jobs rather than only a newly seeded lawn. Its 18% phosphorus supports root formation, while the supplied product facts describe slow, steady release of nitrogen and iron for greening. The stated coverage of 5,000 square feet helps buyers plan a larger application. Because it contains phosphorus, local restrictions may affect where it can be used.
- 12-18-8 analysis with 18% phosphorus
- For seeding, overseeding, and sod
- Granular form
- Listed coverage is 5,000 square feet
- Phosphorus-containing lawn fertilizer is restricted in some states; local rules may limit use.
Skip it if you live where phosphorus lawn applications are restricted; check local rules before using this phosphorus-containing formula.
Choose this Jonathan Green formula for a larger fall seeding, overseeding, or sodding job that matches its 5,000-square-foot coverage. Its phosphorus content makes local lawn-fertilizer rules an important boundary before application.

4. Jonathan Green Green-Up 15,000
- Weight: 45 lb
- Form: Powder
Best for: Broad-area seeding and sod.
Why it ranks #4: The seeding-and-sodding 12-18-8 formula comes in a 45-pound package listed for 15,000 square feet, suited to larger projects.
A stated 15,000-square-foot coverage area makes Jonathan Green Green-Up Lawn Food the broad-area option for fall seeding, overseeding, or sodding. Its 12-18-8 formula is rich in phosphorus for root formation, pairing wide project coverage with a nutrient profile aimed at establishing new grass.
This powder-form fertilizer is intended for new grass seedlings, overseeding, and sod, so it can cover varied establishment work across a large lawn. The 18% phosphorus in its 12-18-8 analysis supports root development, while its listed 15,000-square-foot coverage helps buyers plan a broad application. Directions specify applying with a rotary, drop, or handheld spreader on the same day as seeding or sodding, making timing and spreader access part of the workflow.
- 12-18-8 analysis with 18% phosphorus
- For seeding, overseeding, and sod
- Listed coverage is 15,000 square feet
- Directions allow rotary, drop, or handheld spreaders
- The product is listed in powder form rather than granules.
Skip it if you prefer granular fertilizer; this product is listed as powder, while Jonathan Green 11540 is listed in granular form.
This Jonathan Green size fits buyers establishing a broad lawn who can apply fertilizer the same day as seeding or sodding with a listed spreader. Its powder form may not suit those seeking granules.

View on Amazon#5 · Best High-Phosphate Formula
5. Scotts Turf Builder Starter Food
- Weight: 3.3 lb
- Form: Granules
Best for: Repeat feeding for new grass.
Why it ranks #5: Its 24-25-4 formula is made for new grass and also works for sod and plugs, though the product data does not specifically identify fall use.
A scheduled second application at two to four weeks gives Scotts Turf Builder Starter Food a defined follow-up step after planting. Its 24-25-4 formula supplies 25% phosphate for root development, making it a fit for fall seed, sod, sprigs, or reseeding when repeat feeding is manageable.
Apply the granules at planting, then again at two to four weeks; the supplied guidance says the second feeding sustains nutrition while roots and blades develop. That schedule helps buyers plan establishment as a two-pass routine rather than a single application. The formula is safe for any grass type and also suits sod and grass plugs. Scotts reports thicker, quicker growth versus unfed grass, though the product is not sold in Florida.
- 24-25-4 formula with 25% phosphate
- For seed, sod, sprigs, and reseeding
- Safe for any grass type
- Listed follow-up application at two to four weeks
- Not sold in Florida.
Skip it if you are in Florida; Scotts states this product is not sold there, so it is not an available option for your lawn.
Scotts suits buyers who want a specified second feeding during new-grass establishment and are tending seed, sod, sprigs, or a reseeded lawn. Account for its two-application schedule and Florida availability boundary.

6. Jonathan Green Green-Up 1,500
- Weight: 4.5 lb
- Form: Granules
Best for: Small-area seed and sod work.
Why it ranks #6: This 12-18-8 seeding-and-sodding fertilizer supports new roots, but its listed 1,500-square-foot coverage is the smallest among the similar Jonathan Green options.
Coverage of 1,500 square feet makes this Jonathan Green Green-Up size suited to a smaller fall seeding or sodding job. The 12-18-8 analysis, including 18% phosphorus, supports root formation in new seedlings, while the same formula also serves overseeding and sod applications.
This granular fertilizer is formulated for seeding, overseeding, and laying sod, giving it flexibility for small establishment projects. Its phosphorus-rich 12-18-8 analysis supports root formation, while the listed coverage of 1,500 square feet helps set expectations for the area one package can treat. The product facts also specify use on cool-season grasses including Kentucky bluegrass, tall fescue, and ryegrass, useful when matching the application to common fall lawn types.
- 12-18-8 formula with 18% phosphorus
- For seeding, overseeding, and sod
- Listed coverage is 1,500 square feet
- Safe-use information names cool-season grasses including bluegrass, fescue, and ryegrass
- Coverage is limited to 1,500 square feet, so larger jobs require more product.
Skip it if you are treating more than 1,500 square feet with one package; this listed coverage is aimed at a smaller project.
Choose this size for a smaller fall seed, overseeding, or sod project, especially with a named cool-season grass. Its 1,500-square-foot coverage is the key boundary for buyers planning a larger lawn.

View on AmazonAvoid phosphorus-rule and runoff problems
Check local phosphorus rules before choosing a starter fertilizer, because several options here contain substantial phosphorus and local restrictions may apply. Jonathan Green’s product information specifically warns that phosphorus runoff can threaten water quality and that some states restrict phosphorus-containing fertilizer on non-agricultural lawns. This makes the high middle number in a fertilizer analysis more than a simple comparison point: a formula intended for new roots may not be permitted or appropriate in every location.
Do not assume that a product’s seeding label overrides local requirements. Confirm current local guidance, read the package directions, and avoid applying fertilizer where runoff could carry it into drains or waterways.
The listed products do not provide enough information to determine which jurisdictions allow each formula, so buyers need to verify that before purchase and application.
Match the package to the seeded area
Match stated coverage to the area you are seeding rather than assuming similarly named products are interchangeable. Jonathan Green’s Green-Up options share a 12-18-8 analysis but are listed for 1,500, 5,000, and 15,000 square feet, with different package weights. Buying by formula alone can leave you with an unsuitable amount for your project; applying a package intended for a larger area over a smaller lawn could also conflict with the label rate.
The Andersons package covers up to 5,000 square feet, while Greenview’s supplied product details do not state an area coverage figure. Scotts is a 3-pound package, but the provided data likewise does not specify coverage.
Use the exact bag’s directions and measured lawn area to set the application amount; do not infer rates from weight or product family.
How to Choose Fall Grass-Seed Fertilizer
Fall-use fit and seed compatibility
Look for a product that explicitly supports new turf and, when possible, names fall use. The Andersons New Lawn Starter is the only listing here that specifically calls out ideal spring and fall applications, and it is formulated for establishing new turf. Greenview Solutions Starter Fertilizer is intended for seeding a new lawn or repairing bare spots anytime during the growing season.
The Jonathan Green Green-Up products are designated for seeding and sodding, while Scotts is intended for new grass, sod, plugs, or reseeding; neither listing specifically identifies fall. Buyers who want the clearest documented seasonal fit should favor The Andersons, while those prioritizing a broad seeding use case can consider the other labeled starters.
Nutrient analysis and feeding details
Compare the NPK numbers and any stated release or feeding details rather than treating all starter fertilizers as equivalent. The available formulas range from Greenview’s 10-18-10 and Jonathan Green’s 12-18-8 to The Andersons’ 20-27-5 and Scotts’ 24-25-The Andersons lists quick- and slow-release nitrogen, micronutrients, and 1% iron; Greenview says it feeds for up to eight weeks.
Jonathan Green describes its formula as phosphorus-rich for root formation, while Scotts’ listing highlights phosphate for root development. Buyers seeking a specifically stated feeding duration may prefer Greenview; buyers comparing higher phosphorus analyses may look at The Andersons or Scotts.
Follow label rates and local phosphorus rules rather than selecting by the largest number alone.
Coverage and package format
Choose a package whose stated coverage matches your seeded area, and verify the application rate on its label. The Andersons covers up to 5,000 square feet; Jonathan Green offers listed coverage of 1,500, 5,000, and 15,000 square feet in three package sizes. Greenview’s 16-pound bag and Scotts’ 3-pound bag do not include a coverage figure in the supplied product data, so weight alone cannot establish how much lawn either covers.
The Jonathan Green 15,000-square-foot option suits a larger area, while its 1,500-square-foot version is sized for a smaller project. Buyers with a mid-sized area can compare the two stated 5,000-square-foot options, then use bag directions to confirm the correct rate.
Which fertilizer should I choose for fall seeding?
Choose The Andersons New Lawn Starter if you want the clearest fall-specific fit: its listing names fall applications, gives a 20-27-5 analysis, and states coverage up to 5,000 square feet. For new lawns or bare-spot repairs at any point in the growing season, Greenview Solutions Starter Fertilizer offers a 10-18-10 formula and feeding for up to eight weeks. If you prefer a 12-18-8 fertilizer specifically designated for seeding and sodding, choose Jonathan Green Green-Up 5,000 for its stated 5,000-square-foot coverage, or Jonathan Green Green-Up 15,000 for a larger listed area.
The smaller Jonathan Green Green-Up 1,500 fits a more limited coverage need. Choose Scotts Turf Builder Starter Food for its 24-25-4 analysis, while noting its listing does not specifically call out fall.
Frequently Asked Questions
When should I apply starter fertilizer when planting grass seed in fall?
Apply it at seeding only when the product label directs that timing. The Andersons listing explicitly identifies fall applications; the other products’ supplied descriptions do not confirm fall-specific timing. Follow the selected product’s label for application instructions, and check local rules before using a fertilizer that contains phosphorus.
Should I use starter fertilizer again after grass seed germinates?
Do not automatically reapply after germination. Product feeding periods and directions differ, and the supplied information does not establish a universal repeat schedule. Check the label for reapplication timing and rates; Greenview’s listing says it feeds for up to eight weeks, which is not, by itself, an instruction to apply again.
Can phosphorus fertilizer be used on lawns where local rules restrict it?
Only if local rules allow that product and use. The listed fertilizers include analyses with phosphorus, but restrictions vary by location and may limit application. Check your local requirements before applying, and follow the product label; do not assume a starter fertilizer is exempt because it is intended for new grass.
How do I choose among the listed coverage areas?
Match the listed coverage to the area you need to treat, using the product label to confirm application rates. The Jonathan Green options list coverage of 1,500, 5,000, and 15,000 square feet. The Andersons listing states coverage up to 5,000 square feet; do not treat coverage figures as interchangeable across products.
Which listed fertilizer gives the clearest fall-specific fit?
The Andersons Premium New Lawn Starter is the clearest fit based on the supplied product information: it names spring and fall applications, specifies a 20-27-5 formula, and states coverage up to 5,000 square feet. Greenview is an alternative for seeding or bare-spot repair, with a 10-18-10 formula and feeding for up to eight weeks.
Final Words
For fall seeding, choose The Andersons Premium New Lawn Starter if you want the listing to explicitly name fall use, with a 20-27-5 formula and coverage up to 5,000 square feet. Greenview is a strong alternative for seeding or bare-spot repair during the growing season. For a 12-18-8 option, select the Jonathan Green coverage size that fits your area; Scotts is another option, though its listing does not specifically call out fall.
