Best Moss Spray For Lawns: Compare Sprays and Lawn Treatments

#1 · Best Overall

1. Lilly Miller Moss Out

• Weight: 11 lb
• Form: Liquid Concentrate

Best for: Concentrate for lawn moss.

Why it ranks #1: This lawn-specific liquid concentrate kills moss, helps prevent new growth, and covers up to 2,000 square feet without harming grass.

A 35-percent ferric sulfate liquid concentrate gives Lilly Miller Moss Out its clearest distinction, pairing fast-acting moss control with prevention of new growth. The stated coverage is up to 2,000 square feet, making it a practical option for lawn owners treating a defined area rather than seeking a multi-surface cleaner.

The concentrate form and coverage claim of up to 2,000 square feet help buyers gauge whether one container suits the lawn area they want to address. Its listed action both kills moss and helps prevent new growth, so the use case extends beyond clearing visible patches. The product description says it does not harm lawn grass, an important fit for treating moss within an existing lawn. The supplied details do not specify a hose-end applicator or application dilution.

Skip it if you need a ready-to-spray hose-end bottle; Bonide MossMax attaches directly to a garden hose and mixes as you spray.

Choose Lilly Miller if you want a ferric sulfate concentrate for lawn moss, with stated coverage up to 2,000 square feet. Its fit is less clear if you need a specified spray setup or detailed dilution directions.

#2 · Best Hose-End Spray

2. Bonide MossMax

• Weight: 2.3 lb
• Form: Spray

Best for: Hose-end lawn and surface spray.

Why it ranks #2: The 32-ounce ready-to-spray bottle attaches to a garden hose and is described as killing actively growing lawn moss within hours.

A hose-end bottle that mixes concentrate with water as you spray makes Bonide MossMax a convenient choice for lawn moss and algae treatment. The ready-to-spray formula also lists roofs, decks, patios, sidewalks, and fences among its uses, extending its role beyond lawn care.

The 32-ounce ready-to-spray bottle attaches to a garden hose, and water automatically mixes with concentrate during application; that workflow avoids separately measuring and mixing a tank. MossMax is described as fast acting on actively growing moss and algae, with results within hours. Its listed surface uses include roofs, decks, patios, sidewalks, and fences, while the nonstaining formula is a useful attribute for concrete. The product also gives grass an opportunity to fill in after lawn moss is killed.

Skip it if you want a dry granule treatment for a moist lawn; Scotts MossEx is a shaker-jug granule intended for lawn application.

Bonide suits buyers who want hose-end application for moss or algae across lawns and listed outdoor surfaces. Consider its broad use case, but note that the supplied details do not state a treatment-area coverage figure.

#3 · Best Spot Treatment

3. Sunday Dandelion Doom

• Form: Liquid

Best for: Iron-based spot treatment.

Why it ranks #3: This liquid spot treatment targets moss and algae as well as weeds, with chelated iron and visible results described within hours.

Chelated iron (FeHEDTA) is the stated active approach in Sunday Dandelion Doom, a liquid spot treatment for moss, algae, lichen, and broadleaf weeds. The product describes visible results in hours and says it targets weeds down to the root while keeping grass unharmed.

The spot-treatment direction suits buyers addressing individual patches rather than applying broadly across a lawn. Sunday lists moss, algae, lichen, dandelions, and other broadleaf weeds as targets, so one liquid product addresses several unwanted growth types. Its chelated iron formula is described as producing visible results in hours and killing down to the roots; repeat application is recommended as needed for long-lasting control all season. The label information says not to apply when rain is expected within several hours.

Skip it if you want a hose-end treatment across lawn and exterior surfaces; Safer Brand 5324-6 attaches directly to a garden hose.

Sunday suits lawn owners spot-treating moss alongside weeds, algae, or lichen with an iron-based liquid. Keep the spot-treatment direction and rain restriction in mind when choosing where and when to apply it.

#4 · Best Multi-Surface

4. Safer Moss and Algae Killer

• Weight: 2.3 lb
• Form: Spray

Best for: Multi-surface hose sprayer.

Why it ranks #4: Its 32-ounce hose sprayer uses potassium salts and is listed for moss and algae on lawns, roofs, decks, siding, and walkways.

A ready-to-use formula that attaches directly to a hose lets Safer Brand treat moss and algae across several outdoor surfaces without a separate mixing step. Its listed uses include roofs, decks, siding, walkways, lawns, and more, giving it a broader surface scope than a lawn-only treatment.

The 32-ounce hose sprayer connects directly to a garden hose, a practical setup for applying the ready-to-use formula across listed areas such as roofs, decks, siding, and walkways. Potassium salts are the stated active approach for killing moss and algae, and the product is OMRI listed for organic use. That combination suits buyers looking for one hose-applied option across lawn and exterior surfaces. The supplied information does not provide a coverage figure, so it cannot establish how much area a bottle treats.

Skip it if you need a stated coverage area for planning a granule application; Jonathan Green Lawn Moss Control lists coverage of 5,000 square feet.

Safer Brand suits buyers seeking a hose-connected moss and algae treatment for both lawn and listed exterior surfaces. Its OMRI listing may matter to organic-use shoppers, while the lack of stated coverage leaves area planning uncertain.

#5

5. Scotts MossEx

• Weight: 8 oz
• Form: Granule

Best for: Shaker-jug spot treatment.

Why it ranks #5: This ready-to-use lawn granule kills moss without harming grass, includes nutrients, and treats 1,250 square feet per 4.59-pound jug.

A ready-to-use shaker jug makes Scotts MossEx straightforward to apply to mossy lawn areas without mixing a concentrate. Its granules also contain nutrients to help develop green grass, while one 4.59-pound jug is listed to treat 1,250 square feet.

The shaker-jug format supports spot treatment of mossy patches, and the ready-to-use granules remove the need to prepare a spray mixture. Scotts recommends applying in winter or spring while moss is actively growing, with the lawn moist and tall grass mowed to expose low-growing moss. That timing and preparation give buyers a specific application workflow. The product is described as killing moss without harming lawn grass, and its included nutrients help develop green grass.

Skip it if you need a hose-end treatment for decks and fences as well as lawn; Safer Brand 5324-6 is listed for those surfaces.

Scotts fits lawn owners treating moss patches with a ready-to-use granule and a defined application season. Follow its moist-lawn and mowing guidance, and consider the 1,250-square-foot coverage when planning treatment.

#6

6. Jonathan Green Lawn Moss Control

• Weight: 20 lb
• Form: Granule

Best for: Large-area granule treatment.

Why it ranks #6: This lawn-specific granule treats 5,000 square feet and prevents and treats moss, but it is not a spray and excludes St. Augustine grass.

A stated 5,000-square-foot coverage makes Jonathan Green Lawn Moss Control a fit for buyers treating a broader lawn area with granules. It both treats existing moss and helps prevent new growth, though the product specifically says it will not repair damage already present beneath the moss.

The granule form is applied to a dry lawn and watered afterward, giving buyers a defined two-step application routine. Its listed coverage of 5,000 square feet helps with planning for a larger treatment area. The product controls and kills all moss types while also helping prevent new moss, but it does not repair underlying lawn damage. Important restrictions exclude newly seeded lawns and St. Augustine grass; directions also say to wait two weeks before seeding, so lawn condition and follow-up plans matter.

Skip it if you have St. Augustine grass or a newly seeded lawn; Scotts MossEx is listed for lawn use without those specific restrictions.

Jonathan Green fits buyers treating moss across a larger lawn who can apply granules to dry grass and water afterward. Avoid it on newly seeded lawns and St. Augustine grass, and remember it will not repair existing damage.

#7

7. ECO Garden PRO Weed Killer

• Weight: 9 lb
• Form: Liquid

Best for: Vinegar-based spray option.

Why it ranks #7: This ready-to-spray liquid lists moss among several targets, but its supplied details do not specify lawn moss coverage or application directions.

A spray-ready, one-gallon vinegar weed killer makes ECO Garden PRO a liquid option for buyers seeking moss control alongside broader weed targets. Its title also identifies clover, lawns, green grass, and poison ivy among its intended targets, and describes the herbicide as glyphosate free.

The one-gallon format and included sprayer, as stated in the title, give buyers a ready-to-use liquid application setup rather than a granule routine. The product is identified as a vinegar weed killer and lists moss among its targets, alongside clover, weeds, green grass, and poison ivy. Its title also presents it as kid safe and pet safe, though the supplied safety information still directs users to keep it out of children's reach and avoid contact with skin and eyes. Coverage and application directions are not provided.

Skip it if you need a listed treatment-area figure and detailed lawn directions; Jonathan Green Lawn Moss Control specifies 5,000-square-foot coverage and application steps.

ECO Garden PRO may suit buyers seeking a spray-ready vinegar product listing moss among several weed targets. Its supplied details do not establish coverage or specific application directions, so those boundaries matter when planning lawn treatment.
