When to apply summer fertilizer:

  • All-in-One Liquid Lawn Food: Apply as soon as possible. Make sure highs are below 90 degrees Fahrenheit when applying. 
  • Liquid Lush: Apply 1-2 weeks before peak heat.
  • Liquid Lush improves absorption of All-in-One Liquid Lawn Food, so ideally apply both at the same time.
  • Split each pouch into multiple applications if your lawn is <2,500 square feet

  • Each pouch covers up to 5,000 square feet.

    All summer lawn fertilizers are not created equal

    What makes grass greener than applying fertilizer once in the summer? Applying fertilizer twice.

    Especially when it's all-natural liquid fertilizer that's designed with clean and safe ingredients.

    But wait, what's better than applying fertilizer twice? Adding soil amendments like humic acid and kelp to help keep your grass green all summer.

    Your grass is THIRSTY!

    Warm- and cool-season grasses alike suffer heat stress in the summer. The solution isn't always more water.

    Watering too frequently can stunt growth and waste water. Water one time every 1-3 weeks in the summer. Overwatering makes grass weak. 

    Save time and money. Don't over-water your lawn. Keep your grass green with natural soil amendments to improve water retention!

    The Summer Lawn Fertilizer Kit will make your grass a lean, green, water-drinking machine

    Instantly improve your lawn's ability to absorb, retain, and utilize water in the soil. This is crucial during the hot summer months, when water can quickly evaporate and leave your lawn dry and brittle. Ensure that your lawn stays healthy and hydrated, with the powerful combination of All-in-One Liquid Lawn Food and Liquid Lush promoting healthy growth and water retention.

    The secret ingredient is humic acids

    At the heart of our organic Liquid Lush soil amendment is the power-packed 12% concentration of humic acids, designed to improve water retention and absorption, promote healthy soil and root development, and enhance the effectiveness of All-in-One Liquid Lawn Food. Humic acids are essential for healthy soil and lawn growth, and the Summer Lawn Fertilizer Kit by Gnome is the perfect way to provide your lawn with this crucial ingredient.

    No more dry, brittle grass in the summer

    Our Summer Lawn Fertilizer Kit is designed to make lawn care easy and effective, with everything you need to achieve a healthy and beautiful summer lawn. Promote green growth, root development, water retention, and nutrient absorption. Rejuvenate your soil with bioactive kelp and iron for a visibly deeper and more vibrant green color.

    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?

    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 glyphosates?

    Ewwww, glyphosates! Gnomes are highly sensitive to all things toxic and carcinogenic. That's why none of our fertilizer formulas contain glyphosates, 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.
