Best 13-13-13 Lawn Fertilizers for Balanced Grass Feeding
For a lawn fertilizer labeled 13-13-13, choose a product that explicitly lists that balanced ratio and follow its package directions for application. Gardenwise offers slow-release 13-13-13 options in two package sizes, while a 7-pound professional fertilizer also lists micronutrients. Scotts Turf Builder and Simple Lawn Solutions are alternatives for buyers who want different fertilizer formulas rather than 13-13-13.
| Product | Best For | Formula Or Format |
|---|---|---|
| Gardenwise 1/2 Quart | Small-scale use | Slow-release granular, 13-13-13 |
| Scotts Turf Builder Lawn Food | All-grass-type lawn feeding | Granular; formula not specified in the product name |
| Professional 13-13-13 With Micronutrients | Buyers seeking a stated micronutrient addition | Slow-release, 7 pounds |
| Simple Lawn Solutions 15-0-15 | Liquid lawn feeding | Liquid; 15-0-15 |
| Gardenwise 1 Quart | A larger Gardenwise package | Slow-release granular, 13-13-13 |
Gardenwise 13-13-13, 1/2 Quart
This slow-release granular fertilizer is labeled 13-13-13 and is described for outdoor grass, vegetables, roses, flowers, shrubs, trees, lawns, gardens, and potted plants. It is best for buyers who want a small package for limited lawn areas or a range of outdoor planting uses.
Choose this if you specifically want a balanced 13-13-13 product and prefer granular fertilizer. The listed half-quart size is a practical distinction from the one-quart Gardenwise option. Its broad stated use makes it relevant for people tending both grass and other plants.
Limitation: The package is small, so it may not suit buyers treating a large lawn. Check the label for the application rate and area coverage before purchasing.
Scotts Turf Builder Lawn Food
Scotts Turf Builder Lawn Food is a granular lawn fertilizer listed for all grass types. The product name specifies a 12.5-pound package that covers 5,000 square feet. It is best for buyers prioritizing stated lawn coverage and an all-grass-types product rather than a confirmed 13-13-13 formula.
Choose this if you want a lawn-focused option and need a stated coverage figure for planning. The product information provided does not identify it as 13-13-13, so compare the package analysis with your soil or lawn-care needs before treating it as a substitute for a balanced fertilizer.
Limitation: This is not listed as a 13-13-13 fertilizer. Buyers specifically shopping for that ratio should verify the label or select one of the products that names it.
13-13-13 Fertilizer With Micronutrients
This 7-pound slow-release, all-purpose fertilizer is labeled 13-13-13 and lists micronutrients. Its stated uses include lawns, flowers, trees, shrubs, and vegetable gardens. It is best for buyers looking for the specified balanced ratio in a larger package than the Gardenwise half-quart option, with micronutrients called out in the product name.
Choose this if you want a granular fertilizer presented for several garden and landscape uses, not just grass. The slow-release description is relevant to shoppers comparing it with products that do not state a release type.
Limitation: The supplied product details do not name the micronutrients or state lawn coverage. Check the package instructions to determine the proper rate and area for your lawn.
Simple Lawn Solutions 15-0-15 Liquid Fertilizer
This is a liquid lawn fertilizer labeled 15-0-15, not 13-13-13. Its product name lists nitrogen, potassium, humic, fish, and seaweed ingredients, describes it for any grass type and all-season use, and specifies an attached sprayer. It is best for buyers who prefer a liquid lawn product and do not require equal N-P-K numbers.
Choose this if the liquid format and attached sprayer are priorities. Its 15-0-15 analysis is different from a balanced 13-13-13 formula, so it is a comparison option rather than a direct match for the search.
Limitation: It does not provide the 13-13-13 ratio. Confirm that its formula fits your lawn’s needs before choosing it instead of a balanced fertilizer.
Gardenwise 13-13-13, 1 Quart
This one-quart Gardenwise option is a slow-release granular 13-13-13 fertilizer. The product name lists outdoor grass, vegetables, roses, flowers, shrubs, trees, lawns, gardens, and potted plants as intended uses. It is best for buyers who want the same stated formula and broad use as the half-quart Gardenwise product in a larger package.
Choose this if you need more product than the smaller Gardenwise size provides. Both options share the slow-release description and 13-13-13 ratio; package size is the main stated difference in the supplied product details.
Limitation: The product name does not provide a lawn coverage estimate. Check the directions to see whether the package quantity is appropriate for your area.
Buying Guide: Choosing 13-13-13 Lawn Fertilizer
What does 13-13-13 tell you?
The three numbers identify the fertilizer’s stated N-P-K ratio: nitrogen, phosphorus, and potassium. A 13-13-13 label presents equal proportions of these three listed nutrients. It does not, by itself, tell you the right amount to apply to a particular lawn. Follow the package directions and consider the lawn’s needs before selecting a formula.
Should you choose slow-release granules or liquid?
The Gardenwise products and the professional 7-pound option are described as slow-release granular fertilizers. The Simple Lawn Solutions product is a liquid with an attached sprayer. Compare the format with your preferred application method, and use each product only as its label directs. The liquid option is 15-0-15, so it is not a ratio match.
How much product do you need?
Package size alone does not establish lawn coverage. The Gardenwise products are sold in half-quart and one-quart sizes, and the professional fertilizer is listed as 7 pounds. Scotts is the only product here with a stated coverage figure: 12.5 pounds for 5,000 square feet. Compare label rates before estimating how much to buy.
What should you verify before applying it?
- Confirm the N-P-K numbers on the package if you specifically need 13-13-13.
- Check the label for application rates, coverage, and instructions for your grass or garden use.
- Do not assume products with different formulas, such as 15-0-15, are interchangeable.
- For products listing multiple plant uses, verify that the directions cover your intended application.
