Best 27-0-0 Fertilizer Alternatives for Lawn and Garden Use
If you are looking for 27-0-0 fertilizer, note that none of the products listed here has that exact NPK ratio. The closest matches are two 28-0-0 lawn fertilizers, which provide nitrogen without listed phosphorus or potassium. The other options supply potassium or balanced nutrients, so they serve different needs. Compare the label and your soil or plant requirements before choosing; a similar NPK number does not make fertilizers interchangeable.
| Product | Listed NPK | Best suited for |
|---|---|---|
| Petramax Liquid Nitrogen Fertilizer | 28-0-0 | Buyers seeking a liquid nitrogen lawn fertilizer |
| Maximum Green & Growth | 28-0-0 | Buyers comparing a nitrogen-focused lawn food |
| 0-0-26 Foliar Phosphite | 0-0-26 | Buyers seeking a potassium-focused liquid |
| Simple Lawn Solutions High Potassium | 0-0-25 | Buyers seeking potassium for turf |
| 10-10-10 Slow Release Fertilizer | 10-10-10 | Buyers who need a balanced garden fertilizer |
Petramax Liquid Nitrogen Fertilizer
This is a liquid 28-0-0 lawn fertilizer described as a spring and summer product. Its NPK ratio indicates nitrogen as the listed primary nutrient, with no phosphorus or potassium shown. It is a close numerical alternative for shoppers searching for 27-0-0, but it is not the same formulation.
Best for: Lawn owners specifically comparing liquid, nitrogen-focused fertilizers. The product name identifies it as a spray-on grass fertilizer and describes it as a slow-release, high-nitrogen turf builder.
Limitation: The supplied product information does not include application rates or detailed directions. Follow the package label rather than estimating a dose.
Maximum Green & Growth 28-0-0
This liquid lawn food is labeled 28-0-0 and is described as a concentrated blend with quick- and slow-release nitrogen. The product name identifies it for spring and summer use and says it is intended for any grass type. Its nitrogen-focused ratio makes it a close alternative to 27-0-0 for lawn shoppers, but the nutrient percentage differs.
Best for: Buyers who want to compare a high-nitrogen liquid lawn fertilizer with both quick- and slow-release components, as described in the listing.
Limitation: The provided details do not state coverage or application instructions. Check the product label for rates and timing before use.
Turf Supply Inc. 0-0-26 Foliar Phosphite
This liquid fertilizer provides 26% soluble potash and is listed as 0-0-26. The product description says it is intended to provide potassium and support plant defenses during high-stress periods. It is not a nitrogen fertilizer and is not a direct substitute for 27-0-0.
Best for: Turf or ornamental plant owners seeking a potassium-focused liquid product rather than a nitrogen-heavy fertilizer. Listed directions specify 2–6 ounces per 1,000 square feet for turf, applied every two to four weeks, and 1–3 ounces per gallon of water for ornamentals every two weeks.
Limitation: Choose another product if your goal is to supply nitrogen; this formula lists no nitrogen.
Simple Lawn Solutions High Potassium 0-0-25
This liquid lawn fertilizer is labeled 0-0-25 and is marketed for turf vigor and hardiness, particularly in summer and fall. The listing says potassium can help turf manage stress when a deficiency is present. Its ready-to-use hose-end sprayer is described as covering up to 3,200 square feet.
Best for: Lawn owners seeking potassium-focused nutrition and a hose-end application format. It is a useful comparison to 27-0-0 when the lawn’s need is potassium, not nitrogen.
Limitation: The listing notes that potassium application may not produce a visible response. This product does not supply listed nitrogen or phosphorus.
10-10-10 Slow-Release Garden Fertilizer
This granular fertilizer is labeled 10-10-10 and described as a slow-release, all-purpose product for gardens. The listing names vegetables, tomatoes, shrubs, roses, flowers, fruit, and fig trees among its intended uses. Because it contains nitrogen, phosphorus, and potassium in balanced proportions, it differs substantially from 27-0-0.
Best for: Gardeners looking for a balanced granular fertilizer for the listed garden plants, rather than a nitrogen-only lawn product.
Limitation: Avoid treating it as a direct 27-0-0 replacement when you specifically need a high-nitrogen formula. The supplied details do not include application rates.
Buying Guide: How to Choose a 27-0-0 Alternative
What does 27-0-0 mean?
The three numbers on an NPK fertilizer label represent the listed percentages of nitrogen, phosphate, and potash, in that order. A 27-0-0 product is a high-nitrogen formula with no listed phosphate or potash. The 28-0-0 options here are close in ratio, but they are not identical; compare the label and use the product directions.
Should you choose a 28-0-0 product?
Consider a 28-0-0 option if you want a nitrogen-focused lawn fertilizer and the product label fits your grass, season, and application needs. The supplied information identifies Petramax as a spray-on spring and summer product, while Maximum Green & Growth is described as a concentrated liquid with quick- and slow-release nitrogen. The listings provided do not give enough detail to compare their application rates.
When is a potassium fertilizer more appropriate?
Choose a 0-0-25 or 0-0-26 product only when potassium is the nutrient you intend to supply. These products are not substitutes for a nitrogen-focused fertilizer. A soil test can help determine which nutrients are needed and reduce the risk of applying an unsuitable formula.
What else should you check before applying fertilizer?
- Match the NPK ratio to the plant’s nutrient needs and, when available, soil-test results.
- Read the label for application rate, dilution, coverage, and timing.
- Check whether the product is liquid or granular and whether it requires a sprayer or water mixing.
- Do not assume that a fertilizer described for turf is appropriate for garden plants, or vice versa.
Frequently Asked Questions
Is 28-0-0 the same as 27-0-0?
No. Both are nitrogen-focused formulas with zero listed phosphate and potash, but the first number differs. Check the label and follow that product’s application directions.
Which listed products are closest to 27-0-0?
The Petramax Liquid Nitrogen Fertilizer and Maximum Green & Growth are both labeled 28-0-0, making them the closest listed options by NPK ratio.
Can 0-0-25 replace 27-0-0?
No. A 0-0-25 fertilizer lists potassium but no nitrogen, while 27-0-0 is nitrogen-focused. Choose based on the nutrient your lawn or plants need.
Is 10-10-10 a nitrogen-only fertilizer?
No. Its label lists nitrogen, phosphate, and potash in equal proportions. It is a balanced formula, not a direct 27-0-0 alternative.
How should I decide whether my lawn needs nitrogen or potassium?
Use a soil test and consider the lawn’s specific requirements. Product descriptions alone cannot confirm which nutrient is deficient.
