I ordered 2 bottles of the lawn star 16-4-8 lawn fertilizer in a container you hook your hose up to and just spray it. The sprayers failed to work on both of them and I was out of my return window on Amazon. I just emailed the company for any feedback and am waiting for advice to fix it.

Is your lawn lacking in the nutrient department?
If you want to dominate your lawn this season, you’ve come to the right store.
As we step into Spring, it’s vital your lawn has the nutrients it needs to thrive throughout the growing seasons.
And the first thing you should focus on are the big three macronutrients: Nitrogen, Phosphorus and Potassium.
Consider these nutrients the foundation for the overall health, appearance and vitality of your lawn. Without them… You may as well do nothing at all.
Or… Has weed n’ feed left your turf worse for wear?
Look, we understand the short-term appeal of weed n’ feed solutions…
But while we understand the popularity of such products, part of our mission here at LawnStar is to continue to educate consumers that there are better alternatives out there. Solutions that aren’t only safer for you, your family and the environment, but also cheaper in the long run too. You can read more about our mission here.
Aside from the various health concerns surrounding these products, they compromise the long-term health of your lawn by wiping out all the beneficial organisms and fungi present in healthy soil. Your lawn effectively becomes reliant on these chemicals to survive.
We know, you’re probably asking “So how do I turn this thing around?”
It’s not as hard to repair the damage as you may think.
If you’re still using weed n’ feed, stop. Switch to using pre-emergent herbicides for weed control, and develop your lawn fertilization program starting with a well-rounded fertilizer.
Enter LawnStar® 16-4-8
16-4-8 Is the culmination of decades worth of experience in the lawn and turf industry. We’ve dialed in on the perfect 3-1-2 ratio of macronutrients that when applied, injects a powerful shot of vitality into your lawn. Diving into the specifics:
- 16% Nitrogen: A specialty blend of 10% immediate and 6% slow release nitrogen sources ensure your grass experiences rapid greening that doesn’t fade again after a week.
- 4% Phosphorus: Ensures strong, deep root growth and development resulting in a thicker, lusher lawn.
- 8% Potassium: Means you get faster growth, and improved stress tolerance which better protects your turf from good ole’ mother nature.
Plus, we went a step further and packed 16-4-8 with beneficial biostimulants derived from seaweed extract, that further enhance the bioavailability of nutrients in the soil to repair and condition your lawn to a champion state.
Balanced lawn food for green, growth and vitality
The 32 oz. version comes with a sprayer permanently affixed to the bottle for ease of use and portability. It connects to any standard garden hose, and when switched to the ‘ON’ dial, will automatically dilute the fertilizer at the correct rate, ensuring applications are quicker, easier, and make less mess. This size is better for those starting out, or who don’t have a large area to cover – one 32 ounce bottle treats 4,000 sq. ft. of lawn.
The 1 gallon version comes delivered in a rugged container, ready to be diluted in your garden sprayer or hose-end sprayer bottles. Each container mixes to cover 16,000 sq. ft. of lawn, and is best suited towards those who have a large area to cover, or who want ultimate control to mix-in with other products, like: adjuvants (Non-Ionic Surfactant), spray indicators (Blue Spray Pattern Indicator), or their other fertilizers and herbicides.
16-4-8 is highly versatile and suitable for all grass types, including: Zoysiagrass, St. Augustinegrass, Bermudagrass, Centipedegrass, Kentucky Bluegrass, Perennial Ryegrass, Fine Fescue, Tall Fescue & more. Check out the Grass Identification Guide on our Lawn Care 101 blog, to figure out which grass type you have.
We provide detailed, simple to follow usage instructions on the back of both products. No flicking through pages reading tiny disclaimers full of fineprint (just one of the many benefits of opting for greener, safer solutions).
