Best Lawn Fertilizers Similar to 30-0-4 for Greener Grass
If you are searching for lawn fertilizer 30-0-4, note that none of the listed products has that exact nutrient ratio. The closest match is Pennington Full Season Lawn Fertilizer 32-0-5, which has a similar high-nitrogen, potassium-containing formula. The other options suit different needs: Scotts Turf Builder Lawn Food emphasizes fast greening, WinterGuard is labeled for fall use, and Simple Lawn Solutions offers a liquid 15-0-15 formula.
| Product | Best suited for | Listed ratio |
|---|---|---|
| Pennington Full Season 4M | Season-long feeding in a smaller package | 32-0-5 |
| Scotts Turf Builder Lawn Food | Fast visible greening | Not provided |
| Scotts Turf Builder WinterGuard Fall Lawn Food | Buyers looking for a fall-labeled product | Not provided |
| Simple Lawn Solutions Superior 15-0-15 | Liquid application and balanced nitrogen-potassium feeding | 15-0-15 |
| Pennington Full Season 12M | Season-long feeding in a larger package | 32-0-5 |
Pennington Full Season Lawn Fertilizer 4M
Best for: Homeowners seeking a single spring application in a smaller package, with a nutrient ratio close to 30-0-4. The listing identifies this fertilizer as 32-0-5, so it provides a little more nitrogen and potassium than the target ratio.
Pennington says the product is intended as one application for the season and contains beneficial microorganisms to revitalize soil. It also contains 5% iron for deep greening. Those features make it a relevant alternative for buyers who want a seasonal granular fertilizer as well as color support.
Limitation: This is not a 30-0-4 formula. Follow the package label for application rate and timing.
Scotts Turf Builder Lawn Food
Best for: Buyers prioritizing fast, visible greening over matching a specific fertilizer ratio. The product listing says it can produce a greener lawn in three days when used as directed. It also describes two spreader settings, including a “Max Greening” rate, with application restrictions noted on the label.
The listed instructions say children and pets can return to the lawn after the product has been watered in, when used as directed. This makes it important to follow the label’s watering and application directions rather than assuming the lawn is ready immediately after spreading.
Limitation: The provided product details do not state its N-P-K ratio, so compare the package analysis before choosing it as a substitute for 30-0-4.
Scotts Turf Builder WinterGuard Fall Lawn Food
Best for: Shoppers specifically comparing fall-labeled lawn foods. Its name identifies it as a fall product, so it may be more relevant to seasonal fall feeding than a general spring fertilizer. The available product information does not provide additional claims or a guaranteed analysis.
Choose this option if fall timing is your main consideration, but check the product label to confirm its nutrient ratio, application directions, and suitability for your lawn. It should not be assumed to match 30-0-4 based on the product name alone.
Limitation: The supplied details do not state the N-P-K ratio or other performance features.
Simple Lawn Solutions Superior 15-0-15
Best for: Buyers who prefer a liquid lawn fertilizer and want nitrogen and potassium without phosphorus. Its 15-0-15 ratio is lower in nitrogen than 30-0-4, while keeping the same zero-phosphorus and nitrogen-potassium emphasis.
The product includes humic, fish, and seaweed ingredients, and the listing says it can be used on Bermuda, St. Augustine, Zoysia, tall and fine fescue, and Kentucky bluegrass. It is described for spring, summer, and fall use and comes with an attached sprayer.
Limitation: Its 15-0-15 analysis is not a direct match for 30-0-4. Follow label directions for application and coverage.
Pennington Full Season Lawn Fertilizer 12M
Best for: Buyers looking for Pennington’s full-season 32-0-5 formula in a larger listed package. Like the 4M version, it is described as a one-application spring fertilizer with beneficial microorganisms and 5% iron for deep greening.
Choose this if you want the same stated formula and product features as the smaller Full Season option, but need to compare the package size with the area you plan to treat. The 32-0-5 analysis is close to, but not the same as, 30-0-4.
Limitation: The product listing does not establish how much lawn a package covers. Check the label before calculating application needs.
Buying Guide: How to Choose a Lawn Fertilizer
Does the N-P-K ratio need to be exactly 30-0-4?
N-P-K numbers represent nitrogen, phosphate, and potash in that order. A 30-0-4 fertilizer supplies nitrogen and potassium, with no listed phosphate. Among these products, Pennington’s 32-0-5 is the closest stated match, but it is not identical. If an exact analysis is important, verify the package label before buying.
Should you choose granular or liquid fertilizer?
The Pennington products are presented as seasonal lawn fertilizers, while Simple Lawn Solutions is a liquid product with an attached sprayer. Consider the application method you prefer and follow the label for coverage and timing. The listed Scotts Lawn Food highlights spreader settings and fast greening.
How should season and lawn needs affect the choice?
Match the product to the intended season and your lawn-care goal. Pennington highlights one spring application, and WinterGuard is labeled for fall. Scotts Lawn Food emphasizes rapid greening. Simple Lawn Solutions lists use across spring, summer, and fall and names several grass types. Read the full label for local and lawn-specific directions.
