Liquid St Augustine Lawn Food 1 Gal
If you manage a sprawling yard and want a lush carpet of green without constant measuring, this one-gallon jug is your best bet. Large properties demand efficiency, and this formula covers serious ground while delivering a potent dose of liquid nutrients directly to the roots.
You get deep green color quickly because the liquid format bypasses slow soil breakdown. But keep in mind that bulk liquid containers are heavy, so attaching the hose sprayer requires a bit of arm strength.
- Size:1 Gallon
- Application Method:Hose-end spray
- Grass Type:St Augustine
- Additional Feature:Ready to spray bottle
- Additional Feature:Concentrated liquid formula
- Additional Feature:Designed for thick growth

Simple Lawn Solutions Balanced Liquid Fertilizer
Meeting the seasonal demands of warm-season turf requires a reliable balanced NPK ratio that promotes both top growth and root strength. This formula works wonders when plants wake up hungry in the spring and need an extra push to survive the summer heat.
The 16-4-8 ratio hits the sweet spot for general maintenance feeding across multiple grass varieties. Yet, you will need to reapply more frequently than you would with slow-release granular options because liquids wash through the soil profile faster.
- Brand:Simple Lawn Solutions
- Type:Liquid fertilizer
- Size:32 Ounce
- Application Method:Spray bottle
- Nutrient Ratio:16-4-8
- Grass Type:Any grass type
- Additional Feature:Professional grade formula

Liquid St Augustine Lawn Food 32 oz
Standard residential yards need a manageable size that does not require heavy lifting or storage space in the garage. This thirty-two ounce bottle handles average properties with ease, offering targeted nutrition for specific problem areas in your turf.
You can hook up the sprayer in seconds and treat brown patches before they spread across the yard. On the downside, the smaller volume means you might need multiple bottles if your property stretches past a standard suburban lot size.
- Size:32 oz
- Application Method:Hose-end spray
- Grass Type:St Augustine
- Additional Feature:Standard residential size
- Additional Feature:Quick absorption formula
- Additional Feature:Targets thin growth

Liquid St Augustine Lawn Food 8 oz
Tiny yards and apartment patches do not warrant massive agricultural jugs, making this eight ounce concentrate an ideal fit for minimal square footage. Balcony lawns or small courtyards benefit greatly from micro-dosing nutrients without wasting product.
Storage is effortless since the bottle takes up barely any shelf space in your utility closet. However, the limited capacity restricts usage to very small zones, so do not expect this tiny bottle to cover a sprawling backyard.
- Size:8 oz
- Application Method:Hose attachment
- Grass Type:St Augustine
- Additional Feature:Micro sized bottle
- Additional Feature:Targeted growth support
- Additional Feature:Compact storage design
-
Scotts Turf Builder Granular Lawn Food
Granular nutrition remains a staple for homeowners who prefer a slow-release feeding schedule that feeds turf over several weeks. Spreading this solid fertilizer by hand or with a push spreader builds deep, resilient roots that withstand foot traffic and drought stress.
You get predictable, steady growth without the sudden surges associated with liquid treatments. But remember that granular products require thorough watering right after application to prevent burning the delicate grass blades.
- Brand:Scotts

- Size:12.5 lbs
- Application Method:Spread by hand or spreader
- Grass Type:St Augustine
- Additional Feature:Turf Builder formula
