Corn Gluten Meal Liquid Pre-Emergent Weed Control

Lawn Guard is a highly effective, natural weed control product for your lawn and garden. This non-toxic, pre-emergent herbicide is made from corn gluten meal, so it's safe for people and pets.

Unlike traditional herbicides, which target established weeds, corn gluten meal works by inhibiting the root development of weed seeds before they can germinate and establish roots.

Directions for Use:

  1. Shake well before use
  2. Apply evenly to your lawn or garden bed using a sprayer or watering can
  3. Water your lawn or garden after application
  4. For best results, apply the Corn Gluten Meal Liquid Pre-Emergent Weed Control in the early spring before weed seeds start to germinate and in late summer and early fall before autumn weeds can sprout. 
  5. Do not apply this product to newly seeded areas or within 2 weeks of planting seeds or transplanting.

Each pouch covers up to 2,500 square feet. 

Prevents weeds from germinating when applied regularly

Corn gluten meal is most effective when applied in the spring and fall, before weed seeds have a chance to germinate. For best results, it should be applied at a rate of at least 1 pouch per 2,500 square feet of soil, and lightly watered in after application to activate the nitrogen compounds. Applying more often will improve effectiveness.

When applied to the soil, corn gluten meal works by releasing organic compounds that prevent the root development of weed seeds. Additionally, the proteins found in corn gluten meal contain amino acids that serve as a source of nitrogen.

Using corn gluten meal as part of a comprehensive weed control strategy can help prevent the growth of annual grassy weeds such as crabgrass and foxtail, as well as some broadleaf weeds such as dandelion and clover. It is important to note that corn gluten meal is not effective against all types of weeds, particularly established weeds that have already started to grow.

Eliminate weeds without the toxic chemicals

Overall, corn gluten meal is a natural and effective pre-emergent herbicide that can help control weed growth without the use of harsh chemicals. By inhibiting the root development of weed seeds, it provides a safe and eco-friendly alternative to traditional herbicides. Whatever you do, please don’t use products like Roundup that contain glyphosate. Those products are known carcinogens. Don’t get cancer, get Gnome.

Frequently Asked Questions

What types of grass does Gnome work with?

We designed our product line-up to work with all species of turfgrass found in the continental United States, including fescue, bermuda, kentucky bluegrass, zoysia, ryegrass, bentgrass, bahia, and centipede. If you have another kind of grass, or if you’re just concerned about whether Gnome works with your lawn, contact us and give us more details about what you’re workin’ with. We’ll head back to the workshop and see what we can do for you.

Does Gnome replace a professional lawn fertilization program?

Yes! Gnome will deliver all the nutrients that your lawn needs for healthy, green, growth. If you’re concerned about your soil health, order a soil test and let us develop a custom care plan for you, just like a professional service would. We are still amassing our army of lawn-mowing gnomes, but in the meantime you could still use your local lawn mowing service to cut the grass.

Will Gnome work for my climate?

Yes, our Soil IQ™ database covers every climate, grass species, and soil found in the continental US. Once you order your subscription, our gnomes get to work purchasing and compiling even more soil data (including organic matter, cation exchange, calcium content, pH, composition, water capacity and content), climate data (rainfall, average temperatures), and satellite imagery to paint a complete picture of your lawn’s ecosystem. Then we customize the contents and recommendations in your subscription, and even pause your subscription to save you money when your grass is dormant.

Can I order Gnome outside the US?

Alas, we love every lawn and every blade of grass, but right now, we are only available in the continental United States. We hope you still love your lawn and we want to hear from you if you wish Gnome was available in your location. Contact us and let us know where you’re from and you just might inspire us to build a new gnome base outside the US.

How do you manage weeds?

Some lawns need extra help fighting weeds. As you treat your grass with Gnome, herbicides will become less necessary. Once you’re feeding your lawn the right nutrients in the right quantities, it will promote growth in the right species and choke off the growth in invasive weeds.

How do you manage pests?

Integrated Pest Management is the latest in turf science, and how most experts (e.g., golf courses, commercial landscapers) deal with pests — not just weeds but bugs and insects. It’s an iterative process of learning about the pests you’re dealing with, making interventions in and around the lawn, observing changes, and continually improving. We understand that pests can be a huge problem (we’re looking at you, white grubs), and in extreme cases you may need to consider a natural pesticide, but our aim is to make nature more natural, so we always lean toward more natural interventions. Our gnomes are hard at work developing a safe, all-natural pesticide, but we will always recommend using it as minimally as possible.

Is Gnome certified organic?

Yes! We have an all-organic line of liquid fertilizers. They are ideal for grass and outdoor garden use. Our organic formulas are made in Canada and certified as suitable for use in organic farming according to the Canadian Organic Standard (more strict than USDA standards). They are all inspected by EcoCert Canada. In the United States, Organic Materials Review Institute (OMRI) is the primary authority for certifying agricultural products as organic, and we are in the process of listing our organic formulas with OMRI as well!

Is Gnome safe to use on lawns where my kids and pets play?

We’re glad you asked. Yes. *Cue gnome group musical number*

We make grass green, make it grow

Dirt can’t eat, grass sleeps in snow

Drink up well, soil rich like treasure

Safe for kids, your play’s our pleasure

Ahem, we hope you enjoyed that.

First off, please do not drink the fertilizer. Any fertilizer can be dangerous if a human being or a pet consumes it (fun fact: we gnomes are uniquely evolved to digest fertilizer).

But the real concern is whether the fertilizer makes your lawn less safe for play. Traditional, dry, pellet-based fertilizer will remain on your lawn for up to 72 hours, posing a risk to pets and children. With Gnome, you can get back to playing in the grass 4-24 hours after applying the fertilizer (as soon as your lawn dries). Lawns drink, they don’t eat. Liquid fertilizer is just better.

Does Gnome work with lawns larger than 15,000 square feet?

We appreciate your love for your extra large lawn. Our packages are designed for lawns up to 15,000 square feet due to shipping constraints. If you need to cover more than 15,000 square feet of grass, you can always order multiple subscriptions or contact us to help develop a custom care plan.

Can I cancel my subscription?

Yes, you can cancel any time. We are not one of those annoying companies that makes you call in to cancel. We will miss you terribly, but you can log in any time to manage, pause, or cancel your subscription.

What makes Gnome better than competitors?

Great question! Unlike our competitors, our concentrated liquid products contain natural ingredients like urea, iron, kelp, and soybeans without sacrificing the necessary nitrogen your lawn needs to thrive. Our Green Glow is 30% nitrogen, the highest of any liquid lawn food on the retail market. Our nitrogen is also an ideal 50/50 slow release to balance immediate foliar nutrient uptake with lasting grass root and shoot growth. Our sprayers hook up straight to your hose, so you can ditch the spreader and toxic pellets and easily fertilize in just 10 minutes. Most importantly, we’re fanatical about supporting our customers! Our custom plans are tailored to your specific micro-climate and soil composition leveraging leading turfgrass and soil science, and our plans are all backed by the money-back Love Your Lawn guarantee.

Do your fertilizers contain glyphosate?

Ewwww, glyphosate! Gnomes are highly sensitive to all things toxic and carcinogenic. That's why none of our fertilizer formulas contain glyphosate, and they never will. All of our formulas are sourced from premium, natural ingredients like urea, soy, and kelp, so they're safe for your and your loved ones.
