Usage Instructions


For best results apply before 10 am, or after 5 pm. Application during the afternoon should be avoided.

Avoid mowing your lawn 24 hours prior to and after application to ensure proper uptake of 30-0-0.

Application should be repeated every three to six weeks, or on an as-needed basis.

Please ensure your lawn is on a suitable watering schedule. Water is essential to a healthy lawn and proper uptake of nutrients.

The included sprayer will automatically mix LawnStar 30-0-0 with water and dilute it at the proper rate.

1. Shake product well before use

2. Attach sprayer to a standard garden hose. Switch on water supply

3. Turn sprayer to the “ON” position. Important note: Push in plastic safety tab before attempting to adjust dial

4. Slowly apply the spray in a side-to-side motion, being sure to cover the area evenly. Aim to apply at a rate of 5–10 oz. per 1,000 sq. ft.

For less severe deficiency/maintenance, apply 5 oz. per 1,000 sq. ft.
For more severe nutrient deficiency, apply 10 oz. per 1,000 sq. ft.

May cause staining. Shake product well before use.

Your engine for green & growth

If you want a denser, lusher, more vibrant lawn this year… You’re looking in the right place.

Before anything else, it’s vital you ensure that your lawn has a steady supply of high quality, highly bioavailable nitrogen. Simply put, it needs this in order to thrive.

Without it, your lawn will show various nitrogen deficient symptoms:

  • Slow growth
  • Thin patches that allow weeds to grow
  • Yellowing blades
  • Maybe even the early stages of disease

While you can add micronutrients, biostimulants, and amino’s into your lawn care fertilization program… Without a good source of nitrogen, your efforts (and money) will go to waste.

Picture this…

You decide to give your car some upgrades one day. You can either opt for some new wheels, seats, a sound system, and paint job.

Or… Replace that rusty old engine that has been “just getting by” for the last year or two.

Well, you did always hate that red color after all… So, upgrades it is.

Things are going great the first couple of weeks. The seats are much comfier.

Until one morning, when you’re already late for that place you’ve got to be, your car doesn’t start.

The point is: when it comes to lawn care, ensuring you have a strong foundation of core nutrients is how the pro’s do it… And how you should too.

And when it comes to green and growth, nitrogen is that foundation.

Not all nitrogen is made equal

When looking at high nitrogen fertilizers, it’s important to look at their ratio of immediate release versus slow release nitrogen.

You might be surprised to see that many liquid nitrogen solutions will contain little to no slow-release nitrogen. The reason for this is quite simple: it costs more to produce.

When you apply any kind of fertilizer, your lawn will naturally absorb as much as possible (especially if it has been starved of nutrients).

But too much of a good thing ain’t always a good thing.

As you pass a certain threshold (around 20%) of immediate release nitrogen, you get into the burn danger zone. (Yes, the same thing that causes those pesky yellow spots caused by your dog’s urine).

Fertilizers with low nitrogen %’s can get away with using immediate (Urea) nitrogen only because the concentration is so low.

But opting for low concentrations isn’t economical or realistic for those who want to really dominate on their lawns – else you’d be reapplying all the time.

Sometimes, you need more horsepower.

…Which is why you need a good proportion of slow release nitrogen in the mix. This source of nitrogen is absorbed by your turf over the course of weeks, not hours.

Meaning you get more effective results that last longer, while greatly reducing the risk of lawn burn.

Meet LawnStar® 30-0-0

30-0-0 Is the culmination of decades worth of experience in the lawn and turf industry. We’ve dialed in on the perfect blend of immediate and slow release nitrogen sources, that when applied, kickstart the mechanisms involved in photosynthesis and growth into overdrive.

We did a lot of testing to land on the ideal ratio of fast and slow release nitrogen.

In the end, we decided that one third immediate release was imperative for rapid green-up and growth, while two thirds slow release offer superior longevity of results and protect against dreaded lawn burn.

If your lawn is suffering from nitrogen deficiency, 30-0-0 is the first item you should add to the repair program.

High nitrogen lawn food for unparalleled green & growth

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.

30-0-0 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).

Choose the right upgrade today

You got this far, so you’re clearly interested in levelling up your lawn. We want to remind you that, as always, you’re order is backed by our Evergreen Guarantee (you can read more about that here).
