If you’re serious about giving your lawn a strong start, a 13-25-12 lawn fertilizer can make a real difference. This specific N-P-K ratio is higher in phosphorus (the middle number), which is key for developing deep, healthy root systems. Many gardeners reach for this blend when planting new grass, reseeding bare patches, or laying sod. Without enough phosphorus, young grass can struggle to establish, leading to thin, patchy lawns that invite weeds and disease. In October of 2026, we’ve gathered 10 of the best 13-25-12 lawn fertilizers to simplify your search.
From trusted brands like Scotts, The Andersons, and Pendelton Turf Supply, these products span a price range of $13.99 – $65.98. Whether you’re a first-time lawn owner or an experienced gardener looking for a fast green-up and stronger roots, there’s an option here for you. Keep an eye on coverage area and nutrient release type – some are quick-release for immediate feeding, while others are slow-release for longer-lasting results.

Pros
- 15% slow-release nitrogen provides consistent feeding and reduces the risk of fertilizer burn.
- Works across all grass types, so you don't need separate products for different lawn areas.
- Helps improve soil structure and moisture retention, leading to a healthier, more resilient lawn.
- Easy to use with clear instructions; no special equipment required.
- Good coverage per bag (6,250 sq ft) for the price.
Cons
- No weed or pest control included; you may need additional products for those issues.
- As a new product at the time of this writing, there are no customer reviews to verify real-world performance.
- The 25-7-12 ratio is a standard all-purpose mix; it may not be ideal for lawns needing a higher phosphorus or potassium boost for specific conditions.
The Supply Solutions 25-7-12 Lawn and Turf Fertilizer is a straightforward granular fertilizer designed for anyone looking to maintain a healthy, green lawn without the hassle of constant reapplications. Its main selling point is the 15% slow-release nitrogen, which feeds your grass over several weeks rather than all at once. This makes it a good option for homeowners, property managers, and even groundskeepers who want reliable, steady growth with less risk of burning the turf.
In terms of performance, the balanced 25-7-12 NPK ratio delivers a solid dose of nitrogen for color and growth, moderate phosphorus for root development, and potassium for overall stress tolerance. The added sulfur helps improve soil structure and nutrient uptake. While we haven't tested this specific batch, similar slow-release fertilizers generally provide a more even greening effect compared to quick-release formulas. The 25-pound bag covers 6,250 square feet, which is a practical size for medium to large lawns.
Build quality is standard for a granulated fertilizer: dry, free-flowing particles that spread easily with a broadcast or drop spreader. The bag is sturdy and resealable, though you'll want to store it in a dry place to prevent clumping. Application instructions are clear and printed on the label, covering rates for different grass types and seasons. There's no strong odor, which is a plus for residential use.
One honest drawback is the lack of any weed or insect control. If you're dealing with dandelions or grubs, you'll need a separate product. Also, because this is a relatively new listing (no customer reviews yet), long-term performance data from actual users is unavailable. However, based on the ingredient list and typical slow-release behavior, it should deliver consistent results for general lawn maintenance.
Overall, the Supply Solutions 25-7-12 is a solid, no-frills choice for routine feeding of any grass type. It's especially good for those who prefer a 'set it and forget it' approach, thanks to the slow-release nitrogen. If you need a simple, effective fertilizer for a large lawn and don't require additional treatments, this bag is worth considering.

When choosing a lawn fertilizer, consider your grass type and the season. This 25-7-12 formula is a good maintenance feed for spring, summer, or fall. If your soil test shows low phosphorus or potassium, you might need a different ratio. Always apply to dry grass and water in lightly to activate the slow-release granules. Use a calibrated spreader to avoid overlapping and ensure even coverage.
Pros
- Professional-grade formula for high-performance results
- Contains both quick and slow-release nitrogen for immediate and lasting nutrition
- Even particle distribution prevents burning and streaking
- Works on all turf types across multiple seasons
- Includes iron and micronutrients for extra-deep greening
Cons
- Not available for sale in Maryland, limiting accessibility
- Requires reapplication every 4-6 weeks during active growing season, which may be more frequent than some slow-release options
- The 18-lb bag might be heavy for some users to carry
The Andersons Core 24-6-12 Professional-Grade All-Purpose Lawn Fertilizer is a balanced, nutrient-dense option for homeowners who want reliable greening without the guesswork. Formulated with a perfect 4:1:2 ratio, it delivers 24% nitrogen, 6% phosphate, and 12% potash, plus iron and micronutrients for total nutrition. This product is designed for all turf types and can be used across spring, summer, and fall, making it a versatile addition to any lawn care routine.
What really makes this fertilizer stand out is its dual-action nitrogen. The quick-release portion provides an immediate green-up after application, while the slow-release nitrogen keeps feeding your lawn for up to six weeks. This means you’ll see results fast and won’t have to reapply as often as with some all-quick-release formulas. The super-fine particles are another highlight; they ensure even distribution with twice the particle count per square foot, reducing the risk of burn or patchy growth.
In real-world use, the coverage is impressive. An 18-lb bag covers up to 6,200 sq ft, which is great for medium to large lawns. The included iron gives an extra-deep greening that makes your turf look lush and healthy. That said, the product requires reapplication every four to six weeks during the growing season to maintain results, and it’s not available for purchase in Maryland, which is a notable limitation for some buyers.
Build quality is typical of professional-grade products: the granules are consistent and spread easily with a standard rotary spreader. The bag is durable and resealable, but at 18 pounds it can be a bit heavy to lift and pour. Overall, The Andersons Core 24-6-12 is a solid choice for anyone looking for a dependable, balanced fertilizer that provides both quick results and lasting nutrition. If you live outside Maryland and need a one-bag solution for season-long feeding, this is well worth considering.
Pros
- Proven to deliver measurable thickness and speed of growth based on thousands of positive reviews
- Simple application instructions that reduce the risk of over or under fertilizing
- Versatile enough for new lawns, overseeding, and even sod or grass plugs
- Trusted brand that has been a staple in lawn care for decades
Cons
- Does not include any weed preventer, so you'll need a separate product if weeds are an issue
- Requires consistent daily watering after application, which can be demanding during dry spells
- Some users might prefer a formula with extra iron for deeper greening, though this one focuses on root growth
Scotts Turf Builder Starter Food for New Grass is a specially formulated fertilizer designed to give your lawn the best possible start. It targets the critical early stages of grass growth, whether you're planting seed in a bare patch, installing sod, or using grass plugs to fill in thin areas. The 24-25-4 nitrogen-phosphorus-potassium ratio is tailored to encourage deep roots and vigorous top growth, which is exactly what young grass needs to compete with weeds and withstand foot traffic.
In real-world use, this product lives up to its claims. Based on numerous customer reviews, it reliably produces a thicker, greener lawn within weeks. Many users report seeing noticeable improvement after the first few waterings, especially when they follow the spreader settings and watering schedule. The fertilizer is easy to apply with a standard broadcast or drop spreader, and the bag clearly states the correct settings for Scotts models. This simplicity helps avoid common mistakes like applying too much or too little.
Build quality is typical of Scotts: a sturdy, resealable bag with clear instructions. The granular form spreads evenly and dissolves well with watering. One potential drawback is that it lacks weed control, so if your lawn has existing weeds you'll need to address them separately. Also, the need for daily watering until the grass reaches 2 inches tall can be a challenge for those with busy schedules or water restrictions. Some users also note that the greening effect isn't as dramatic as some all-in-one fertilizers, but that's by design because this product prioritizes root establishment.
Overall, Scotts Turf Builder Starter Food is a solid investment for anyone serious about growing a new lawn from scratch or repairing patches. Its high rating and volume of positive feedback confirm that it consistently delivers. For the best results, pair it with Scotts grass seed and follow the label's watering guidelines. You'll be rewarded with a lush, healthy lawn that stays green throughout the season.
Pros
- Balanced nutrition that works for a wide variety of garden plants.
- Includes calcium and micronutrients that many general-purpose fertilizers lack.
- Clear application guidelines for different crop types make it easy to use correctly.
- Readily available nitrogen provides a quick boost for early growth.
- Good value for the price compared to similar specialty blends.
Cons
- Synthetic formula, so it may not appeal to organic gardeners.
- Requires careful measurement and timing for best results, not a set-it-and-forget-it product.
- Pelletized lime can raise soil pH, so it's less ideal for acid-loving plants like blueberries without adjustments.
The Pendelton Turf Supply 13-13-13 Garden Grower Fertilizer is a balanced, all-purpose plant food designed for vegetable and flower gardens. It comes in a 6 lb bag and packs an equal ratio of nitrogen, phosphate, and potash, plus pelletized lime and a suite of micronutrients. This combination makes it a solid choice for gardeners who want a readily available source of nutrition that covers the basics while also addressing calcium needs and trace mineral deficiencies.
What sets this fertilizer apart is its thoughtful formulation. The 13-13-13 NPK ratio is a classic balanced blend that promotes leafy growth, strong root development, and flowering without overemphasizing any single nutrient. The addition of pelletized lime not only supplies calcium but also helps buffer soil pH when used as directed. Micronutrients like iron, zinc, and manganese round out the package, giving plants a more complete diet. This matters for crops like tomatoes and peppers, which are prone to blossom end rot when calcium is scarce or uptake is poor.
In real-world use, the fertilizer works best when applied according to the detailed instructions. For tomatoes and peppers, a side-dress after blossom with half a pound per 25 feet of row gives good results. For vine crops, scattering a tablespoon or two around each hill every four to six weeks keeps growth steady. The granular texture is easy to handle, and the pellets dissolve reasonably quickly when watered in. You won't need complicated equipment, just a measuring cup and a garden trowel.
There are a few drawbacks to consider. This is a synthetic fertilizer, not organic, so if you're committed to certified organic methods, you'll want to look elsewhere. Also, the need to measure and apply at specific times means it's not a low-maintenance option. Finally, the lime component will raise soil pH over time, which is fine for most vegetables but could be a problem for acid-loving plants like blueberries or azaleas unless you adjust your overall soil management plan.
Overall, the Pendelton Turf Supply 13-13-13 Garden Grower Fertilizer delivers reliable, balanced nutrition for a wide range of garden plants. It's particularly well suited for home gardeners who grow a mix of vegetables and flowers and appreciate having clear application guidelines for different crop types. If you're comfortable with a standard synthetic fertilizer and want something that covers the basics plus calcium and micronutrients, this product is a solid pick.
Pros
- Works on any grass type
- Pesticide-free and safe around children and pets
- Strengthens roots for long-term lawn health
- Flexible application timing spring, summer, or fall
- Generous coverage area for the price
Cons
- May require multiple applications for optimal results
- 12.5 lb bag may not be enough for very large lawns
- No verified customer reviews to confirm performance
The Scotts Turf Builder Lawn Food is a straightforward, no-fuss fertilizer designed for homeowners who want a healthier lawn without complicated steps. It works on any grass type, so you don't have to worry about compatibility. Whether you have Bermuda, Fescue, Kentucky Bluegrass, or Zoysia, this product claims to feed and strengthen your turf effectively.
One standout feature is its focus on root development. By building deep, strong roots, the grass becomes better at absorbing water and nutrients compared to an unfed lawn. This can lead to improved drought tolerance and overall resilience. The formula is pesticide-free, which is a plus for those concerned about chemicals around kids and pets. Application is simple: you can spread it on a wet or dry lawn during spring, summer, or fall, making it a flexible choice for busy schedules.
The 12.5 lb bag covers up to 5,000 square feet, which is suitable for medium-sized yards. However, if your lawn is larger, you may need multiple bags. The product itself is lightweight (listed at 0.5 pounds, though that seems like a data error for a 12.5 lb bag). In practice, you'll want to use a spreader for even coverage. There are no reviews available yet, so real-world feedback is limited, but Scotts is a well-known brand in lawn care.
Potential drawbacks include the need for repeated applications to maintain results, as most fertilizers require regular feeding. Also, without user reviews, it's hard to gauge how well it performs in different climates or soil types. But based on the features, it's a solid choice for anyone looking for a general-purpose lawn food that's easy to use.
Overall, the Scotts Turf Builder Lawn Food offers a reliable way to feed your lawn without overcomplicating the process. If you're after a simple, effective fertilizer that works on all grass types and builds strong roots, this is worth considering. Just be prepared to reapply as needed for the best results.
Pros
- Fast-acting quick-release nitrogen for visible results within days.
- Deep greening from iron and micronutrients.
- Even coverage thanks to fine particle size.
- Versatile for use in spring and fall.
- Large coverage area per bag.
Cons
- Quick-release formula may require more frequent applications compared to slow-release options.
- Not available for purchase in Maryland.
- Some users may prefer a slow-release formula for longer-lasting feeding.
The Andersons Core 12-8-12 Professional-Grade Quick-Release Lawn Fertilizer is designed for homeowners who want to see rapid greening and growth in their turf. This 18-pound bag covers up to 5,000 square feet, making it a practical choice for medium to large lawns. It's especially beneficial to apply during spring and fall, when your grass needs a quick nutrient boost to recover from winter or prepare for colder months.
What sets this fertilizer apart is its quick-release nitrogen formula. Unlike slow-release options that feed grass gradually, this product delivers immediate nutrition, so you'll notice a difference in color and density within days. The inclusion of 2% iron and micronutrients takes the greening effect even further, giving your lawn a deep, rich hue. The fine particle size is another standout feature it ensures the granules spread evenly, reducing the risk of patchy results or burning.
In terms of usage, the fertilizer is straightforward to apply with a standard spreader. You can reapply it every 4-6 weeks during the growing season, which fits well with a regular lawn care routine. The professional-grade quality is evident, and the fact that it's made in the USA adds to its appeal for buyers who prioritize domestic manufacturing.
However, there are a few things to consider. The quick-release nature means it may require more frequent applications compared to slow-release alternatives, which could be a trade-off for some users. Also, the product is not sold in Maryland, so residents there will need to look for other options. Overall, this is a solid choice for those who value fast results and deep greening.
Verdict: If you're looking for a reliable, fast-acting fertilizer that delivers visible results and deep color, The Andersons Core 12-8-12 is an excellent option. Just be prepared to apply it every 4-6 weeks for best results.
Pros
- Quick greening from fast-release nitrogen, plus long-lasting slow-release portion.
- Iron helps prevent yellowing and improves lawn color without stimulating weeds.
- High potassium content boosts heat and drought tolerance.
- Works well as a scheduled summer application following a balanced spring fertilizer.
Cons
- Lacks phosphorus (0), so not suitable for new lawns or repairing bare spots.
- May need multiple applications per season for continuous feeding.
- Synthetic formula; those seeking organic options should look elsewhere.
The Andersons Premium Lawn Food 28-0-12 is a specialized fertilizer designed for established lawns during spring and summer. It targets the third application of The Andersons Lawn Program, but it works just as well as a standalone feed for homeowners who want a tough lawn that can handle heat and drought. If you have an established fescue, bluegrass, bermuda, or ryegrass lawn and you're seeing stress from rising temperatures, this product is worth a close look.
The standout feature is its dual nitrogen system. Quick-release nitrogen gives you visible greening within days, while the slow-release portion keeps feeding for several weeks. That means you don't have to reapply every few weeks. The iron content is another big plus it deepens the green color without pushing excessive leaf growth, which helps keep your lawn looking clean and manicured. In real-world use, lawns treated with this fertilizer show noticeably darker color and better resilience during dry spells.
Build quality is solid for a granular fertilizer. The particles are uniform and low dust, which means they flow consistently through a rotary spreader. Coverage is straightforward: one 32-pound bag covers 5,000 square feet. The bag itself is sturdy with clear application instructions. No complaints about the packaging or spreading performance.
There are a couple of honest drawbacks. First, this product contains zero phosphorus, so it won't help with new lawns or bare spots that need root development. Second, while it provides extended feeding, you may need to reapply later in the season if you want continuous growth. And finally, it's a synthetic formula, which might not appeal to gardeners committed to organic lawn care.
Overall, The Andersons Premium Lawn Food 28-0-12 is a well-formulated summer fertilizer for established lawns. It delivers fast green-up, long-lasting nutrition, and added heat tolerance. If your goal is a lush, deep-green lawn that can take the summer heat, this is a reliable option just don't expect it to fix bare soil or launch a new lawn.
Pros
- Fast greening results noticeable within days
- Does not stain walkways or patios when applied correctly
- Covers a large area so you get good value per bag
- Easy to apply with a spreader and works on any grass type
- Iron supplement helps strengthen roots for healthier turf
Cons
- Uneven application or hot weather may cause patchy burn spots
- Results may fade after a few weeks, requiring reapplication for sustained color

Designed for homeowners who want a thick, deep green lawn fast, this product works on any grass type and can be used throughout the growing season. It's a popular choice for DIY lawn enthusiasts looking for an affordable boost without professional help.
The standout feature is the 5% iron content, which promotes deep greening in as little as three days. Real-world tests from thousands of users back this up; many report seeing a noticeable color change within the first week. The formula is also designed not to stain concrete or driveways when applied according to directions, a common worry with high-iron fertilizers. Application is straightforward with a spreader, and the bag covers 10,000 square feet, making it suitable for medium to large lawns. For best results, watering lightly after application speeds up the greening process.
In terms of build quality, the product comes as uniform granules that spread evenly using the recommended Scotts spreader settings. The instructions are clear, and the 33.33 lb bag is manageable for most homeowners. While the quick results are impressive, some users note that the deep green color can fade after a few weeks, requiring another application if you want to maintain the look. Additionally, the fertilizer has a strong ammonia-like odor that lingers for a day or two after spreading, which may be a minor inconvenience for some. A few reviewers also caution that uneven application or applying during hot weather can lead to patchy burn spots, so careful spreading is important.
Overall, Scotts Green Max Lawn Food delivers on its promise of fast greening without staining hard surfaces. It's a solid choice for anyone who wants an immediate visual improvement in their lawn's color. Just keep realistic expectations about longevity and be mindful to apply it evenly and at the right temperature.

Pros
- Balanced nutrition supports overall plant health.
- Long-lasting slow release reduces maintenance effort.
- Versatile for many outdoor plant types.
- Easy application with fine granules.
- Promotes strong roots and vibrant blooms.
Cons
- Slow release means results take time; not suitable for quick fixes.
- May require multiple applications for heavy feeders like tomatoes.
- No customer reviews yet, so real-world performance is unverified.
The Gardenwise 13-13-13 Slow Release Granular Fertilizer is an all-purpose plant food designed for outdoor use. It targets gardeners who want a balanced, no-fuss feeding solution for lawns, vegetables, roses, flowers, shrubs, and trees. With equal parts nitrogen, phosphorus, and potassium, this formula supports everything from leafy growth to strong roots and blooming.
The standout feature is its slow-release technology. One application feeds plants for up to 8 weeks, which means fewer trips to the garden center and less guesswork. The fine granules spread easily and make contact with the soil quickly, so nutrients get absorbed efficiently. In real-world scenarios, you can expect steady green-up in lawns and more robust growth in flower beds and vegetable patches.
Build quality is solid. The granules are consistent in size and don't clump, making them simple to apply with a spreader or by hand. The packaging is straightforward and available in multiple sizes, so you can match the quantity to your project. For small patio pots, the 1/2 quart works well, while larger lawns may need the bigger bags.
There are a few honest drawbacks. Because this is slow release, you won't see instant results. It's best for long-term feeding rather than correcting sudden deficiencies. Also, heavy feeders like tomatoes or roses might still need a supplemental water-soluble boost during peak growth. Finally, the product currently has zero reviews, so there's limited user feedback to confirm its performance across different conditions.
Overall, the Gardenwise 13-13-13 is a well-balanced, low-maintenance fertilizer for the average home gardener. If you want consistent, gentle feeding without constant reapplications, it's a solid choice. Just pair it with your regular watering routine and be patient for visible results.
Pros
- Reusable applicator reduces environmental impact and saves money long-term
- Easy-to-read bottle eliminates measuring errors
- Fast application fits busy schedules
- Effective NPK ratio tailored for new grass establishment
Cons
- Requires three weekly applications for best results, which may test patience
- Only suitable for new grass, not for established lawns
- Sprayer may clog if not rinsed thoroughly after use
Scotts Turf Builder Liquid Starter Lawn Food is a go-to choice for anyone establishing a new lawn from seed. With a 7-12-15 NPK formula, it delivers a higher phosphorus and potassium boost to support rapid root development and early growth. Designed for use immediately after grass seedlings sprout, this liquid fertilizer makes the first few weeks of lawn care straightforward and effective.
The standout feature here is the reusable spray applicator. Scotts has designed the bottle to attach directly to a garden hose, and the translucent container shows you exactly how much product remains. This eliminates the guesswork typical of granular starters. The 32-ounce bottle covers up to 600 square feet per feeding and provides three full applications, meaning you can follow the recommended weekly schedule for three weeks without buying additional bottles (refills sold separately).
In practice, the fertilizer mixes easily and sprays evenly. The 10-minute application time is a welcome convenience, especially when dealing with a large new lawn. The real performance comes down to visible results: grass appears greener and denser compared to unfed areas. However, the required weekly cadence demands consistency, and skipping a feeding could slow establishment. Also, while the plastic waste reduction is commendable, the sprayer head may need occasional cleaning to prevent clogs.
One drawback worth noting: this product is specifically formulated for new grass, not for maintaining an established lawn. If you're overseeding or patching bare spots, it works well, but don't expect it to deliver the same green-up for mature turf. At under $26, it offers good value for the concentrated dose you get, especially considering the reusable applicator that reduces future costs.
Overall, the Scotts Turf Builder Liquid Starter Lawn Food delivers on its promise of quicker, thicker new grass with minimal hassle. The thoughtful design and nutrient balance make it a solid buy for DIY homeowners who want a no-fuss start to their lawn project. Just be prepared to commit to the weekly schedule for full results.
