Best Liquid Fertilizer For Zoysia Grass: 10 Options Compared

#1 · Best Overall

1. TPS Nutrients Zoysia Fertilizer

• Form: Liquid

Best for: Zoysia Root-and-Coverage Support.

Why it ranks #1: Explicitly made for zoysia, with stated support for dense green coverage and root strength; the one-gallon liquid suits residential lawn programs.

Zoysia-specific liquid lawn food is the clearest differentiator here: TPS Nutrients targets dense green coverage while supporting root strength. That focus suits homeowners seeking a fertilizer framed around zoysia turf rather than an all-grass formula, with liquid form for integration into a regular lawn-care program.

The product description connects essential nutrients with strong root development, while the listed benefits emphasize thicker turf and vibrant color. Together, those claims make it a focused choice for residential zoysia lawns, yards, and landscaping where coverage and lawn health are priorities. Its liquid form is the stated delivery format, but the supplied details do not provide a mixing rate or hose-end application method, so the product information offers less application guidance than some ready-to-spray options.

Skip it if you need a stated hose-end spraying routine; Scotts Turf Builder Liquid Lawn Food lists a hose-end applicator and a 10-minute application.

For zoysia owners who want liquid nutrition positioned around dense coverage and root support, this is a direct match. Consider the limited application instructions in the supplied details before choosing it for a tightly specified feeding routine.

#2 · Balanced NPK

2. Simple Lawn Solutions 16-4-8

• Form: Liquid
• Weight: 2 lb

Best for: Balanced NPK for Seasonal Feeding.

Why it ranks #2: Its stated 16-4-8 blend supplies nitrogen, phosphorus, and potassium, and the product is described for any grass type.

A 16-4-8 NPK blend paired with seaweed and fish sets this liquid lawn food apart, giving zoysia caretakers a balanced-feed option with added ingredients. Its listed suitability for all grass types, including Bermuda, makes it relevant to mixed warm-season lawns as well as zoysia-only yards.

The concentrated liquid uses nitrogen, phosphate, and potash to support greening and growth, while the balanced 16-4-8 ratio is presented as providing energy for root vigor. Its ready-to-use sprayer supports a straightforward hose-connected workflow: shake the bottle, attach it to the hose, and spray evenly. The product is positioned for spring and summer feeding and for any grass type, so the format can suit routine seasonal care without restricting use to zoysia.

Skip it if you want a formula specifically emphasizing potassium for summer and fall; Simple Lawn Solutions 0-0-25 targets high-potassium feeding.

Choose this for zoysia or mixed-grass lawns when balanced NPK feeding and a hose-connected sprayer fit your spring or summer routine. Its listed seasonal focus is a boundary for shoppers planning other parts of the year.

#3 · Zoysia-Compatible Supplement

3. GS Plant Foods Green Envy

• Form: Liquid
• Weight: 8 lb

Best for: Humic and Fulvic Lawn Add-On.

Why it ranks #3: Explicitly listed for zoysia and contains humic and fulvic acids, but it has no guaranteed N-P-K analysis and is not a nitrogen feed.

Green Envy supplies humic acid, fulvic acid, and organic carbon rather than guaranteed N-P-K, making it a distinct supplement for zoysia care. It can be mixed with a regular fertilizer or applied alone, so buyers can place it alongside an existing feeding routine.

The listed active ingredients include 4.3% humic acid, 6.7% fulvic acid, and 22% organic carbon; the supplied facts do not present it as a nitrogen feed or provide a guaranteed N-P-K analysis. For application, mix 2–4 ounces per gallon of water and spread about one gallon of prepared mixture per 1,000 square feet. Any sprayer is listed as workable, with a hose-end sprayer suggested for large areas, supporting flexible use on zoysia and other named grasses.

Skip it if you want a standalone nitrogen feed; Pendelton Turf Supply 18-3-6 lists nitrogen and 50% slow-release nitrogen.

This fits zoysia owners seeking a humic-and-fulvic product to add to a fertilizer application or spray separately. It is not a substitute for a guaranteed N-P-K feed when nitrogen delivery is the main requirement.

#4 · Fast Greening

4. Scotts Liquid Green Max

• Form: Liquid
• Weight: 8.32 oz

Best for: Fast Hose-On Greening.

Why it ranks #4: The 29-0-0 formula includes iron and is described as suitable for any grass type; listed information says deep greening can appear in three days.

A 29-0-0 nitrogen formula boosted with iron is the defining feature, with deep greening reported in as little as three days. Scotts pairs that color-focused feed with a hose-connected spray bottle, letting a homeowner cover a listed 2,000-square-foot lawn in 10 minutes.

The nitrogen-and-iron combination is aimed at visibly greener turf, while the 10-minute application claim gives busy homeowners a concise feeding workflow. Connect the bottle to a hose and spray; the product is described as suitable for any grass type when turf is actively growing, so zoysia is within its stated scope. The reusable spray applicator can be paired with separately sold refill bottles, offering a way to reuse the applicator for later feedings.

Skip it if you need potassium included in the listed NPK; Scotts Turf Builder Liquid Lawn Food has a 29-0-3 formula.

A fit for zoysia owners prioritizing quick, deep greening and a short hose-on application. Its nitrogen-and-iron emphasis and actively growing turf guidance suit color-focused feeding, while refill purchases require the separate refill bottles.

Listed on Amazon as: Scotts Liquid Green Max Lawn Food, 32 fl. oz.

#5 · Nitrogen and Potassium

5. Scotts Turf Builder Liquid Food

• Form: Liquid
• Weight: 8.32 oz

Best for: Quick Hose-End Routine Feeding.

Why it ranks #5: Its 29-0-3 formula provides nitrogen and potassium for any grass type, and the hose-end format feeds a stated 2,000 square feet in 10 minutes.

A 29-0-3 NPK formula combines nitrogen with potassium, making this Scotts liquid food a practical all-grass option that includes zoysia. The hose-end sprayer and translucent bottle support a simple application workflow, with the listed 2,000-square-foot coverage completed in 10 minutes.

Nitrogen is described as supporting thick, green turf, while potassium helps grass withstand everyday stresses; together, those nutrients give this formula a broader role than a nitrogen-only feed. The hose-end applicator and translucent bottle let users spray while seeing how much product they are using. It is listed for all grass types and actively growing turf, so established zoysia fits the stated use, and the reusable applicator works with separately sold refills.

Skip it if you are feeding new grass before it is established; the supplied guidance limits this formula to actively growing turf.

A suitable option for zoysia owners with established, actively growing turf who value hose-end application and nitrogen-plus-potassium feeding. The new-lawn limitation matters if you are planning a first feed before establishment.

#6

6. Sunday Green Machine

• Form: Liquid
• Weight: 2.6 lb

Best for: Large-Area Two-Pouch Feeding.

Why it ranks #6: The two-pack is stated to cover 10,000 square feet, with a 22-0-3 formula containing nitrogen, seaweed, iron, and potassium.

The two-pack is listed to cover 10,000 square feet, making this Sunday liquid fertilizer a large-area choice for zoysia homeowners. Its 22-0-3 formula combines nitrogen, seaweed, iron, and potassium, with the stated aim of encouraging deep rooting and fortifying grass.

Nitrogen and iron are among the listed ingredients, alongside seaweed and potassium, and the product description links this formula with deep rooting and stronger grass. The supplied directions call for attaching the pouch and universal sprayer to a hose, then spraying, which offers a direct application routine across the listed 10,000-square-foot coverage. Because the source identifies the product as liquid lawn fertilizer but does not specify zoysia in the provided facts, its fit is supported by its grass-feeding purpose rather than a named zoysia claim.

Skip it if you require a product explicitly identified for zoysia; TPS Nutrients Zoysia Grass Fertilizer names that grass in its title.

Consider this for a large lawn where hose application and the listed 10,000-square-foot coverage suit the task. Zoysia-specific claims are not present in the supplied details, so buyers wanting an explicit grass match may prefer another option.

#7

7. Pendelton Turf Supply 18-3-6

• Form: Liquid
• Weight: 2 lb

Best for: Extended Nitrogen Growing-Season Feed.

Why it ranks #7: The 18-3-6 formula has 50% slow-release nitrogen and micronutrients; turf directions specify three ounces per 1,000 square feet.

Half of this 18-3-6 fertilizer's nitrogen is listed as slow release, distinguishing it from liquid feeds described only as readily available. For zoysia caretakers seeking feeding through the growing season, the formula also includes micronutrients and is presented for indoor and outdoor use.

The combination of readily available nutrients and 50% slow-release nitrogen is intended to provide both immediate feeding and extended nitrogen, which can support a longer feeding interval than a formula described only as fast-acting. Micronutrients are listed for plant growth, appearance, and overall health. Turf directions specify 3 ounces per 1,000 square feet mixed in a sprayer, giving zoysia owners a concrete rate; the product is described as an all-purpose fertilizer for use throughout the growing season.

Skip it if you want a ready-to-use hose-end application; Scotts Turf Builder Liquid Lawn Food lists a hose-end sprayer and a 10-minute routine.

Choose this for zoysia feeding through the growing season when a measured spray mixture and extended nitrogen are useful. Its stated turf rate supports planning, but application requires preparing the specified mixture rather than relying on a ready-to-use sprayer.

#8

8. Simple Lawn Solutions 0-0-25

• Form: Liquid
• Weight: 2 lb

Best for: Summer-Fall Potassium Support.

Why it ranks #8: The 0-0-25 formula targets potassium supply and is described for any grass type, making it a targeted option rather than a complete feed.

A 0-0-25 NPK analysis makes potassium the focus of this liquid lawn food, setting it apart for zoysia owners addressing potassium deficiency or stress hardiness. The product is positioned for summer and fall, and its hose-attached sprayer supports even lawn application.

The supplied facts connect potassium with turf hardiness and resilience to temperature changes and stressful conditions when a deficiency is present. Its 0-0-25 formula can be used alone or as a supplement to an existing fertilizing schedule, giving lawn caretakers flexibility when potassium is the specific focus. Directions say to attach the sprayer to a hose, adjust settings for desired coverage, and spray evenly; it is listed for any grass type, including zoysia within that claim.

Skip it if you want nitrogen included in the feed; Simple Lawn Solutions 16-4-8 supplies nitrogen, phosphorus, and potassium in one formula.

A fit for zoysia owners seeking potassium-focused support in summer or fall, either alone or alongside an existing schedule. It is not a complete NPK choice when nitrogen or phosphorus is also the priority.

#9

9. Simple Lawn Solutions 3-18-18

• Form: Liquid
• Weight: 3 lb

Best for: Root-Vigor Nutrient Support.

Why it ranks #9: Its 3-18-18 analysis emphasizes phosphorus and potassium for root vigor, but the listing advises checking local restrictions on phosphorus lawn applications.

The 3-18-18 NPK ratio puts phosphorus and potassium at the center, distinguishing this liquid lawn food from balanced high-nitrogen feeds. For zoysia owners addressing those nutrients or maintaining lawn vigor, the formula offers a concentrated spray option listed for any grass type and summer or fall use.

High phosphorus and potassium are linked in the supplied description to vigorous roots and a stronger lawn, making this formula relevant when those nutrients are the focus. Its liquid form and easy-application positioning support use as a lawn treatment, while the any-grass-type claim includes zoysia within its stated scope. The product information also advises keeping the lawn sufficiently watered for nutrient absorption and flags that some states restrict phosphorus-containing lawn fertilizer, so local rules matter before application.

Skip it if you need a nitrogen-forward feed for greener growth; Scotts Liquid Green Max Lawn Food lists 29-0-0 with iron for deep greening.

This suits zoysia caretakers focused on root vigor or phosphorus and potassium support, especially for summer or fall use. Check local phosphorus restrictions, and keep the lawn sufficiently watered as the supplied guidance advises.

#10

10. Covington Naturals 3-18-18

• Form: Liquid
• Weight: 5 oz

Best for: High-Potassium Root Support.

Why it ranks #10: The 3-18-18 concentrate is described for all grass types, but its phosphorus-heavy analysis is less suited to general zoysia feeding without a known need.

Covington Naturals pairs a 3-18-18 NPK profile with a year-round concentrate claim, emphasizing phosphorus and potassium for lawn and plant nutrition. For zoysia caretakers seeking root-focused support across spring, summer, and fall, its liquid form provides an option listed for all grass types.

The product description links phosphorus with root growth and potassium with overall plant performance, while nitrogen supports leaf and turf-blade growth. That makes the 3-18-18 blend a fit for buyers prioritizing root and plant-strength support rather than a nitrogen-heavy formula. The supplied details call it simple to apply and suitable for all grass types, with use in spring, summer, and fall; however, they do not specify a mixing rate or a particular applicator.

Skip it if you want a ready-to-use sprayer with stated hose directions; Simple Lawn Solutions 16-4-8 supplies those details.

This suits zoysia owners seeking a high-phosphorus, high-potassium liquid for root and plant-strength support across the listed growing seasons. The missing application specifics in the supplied details may not suit buyers who need a defined routine.
