How Organic Fertilization Works
-
Assess your lawn
We look at your grass type, soil, shade, and problem spots, and use soil tests where your local team offers them, so your plan fits your yard.
-
Build the soil
Our custom organic soil builder improves soil structure and fertility, so roots can grow deeper and hold on to water and nutrients.
-
Feed through the season
Slow-release organic fertilizers are applied at the right times of year, matched to your grass’s natural growth cycle.
-
Adjust as it improves
Each visit we check how your lawn is responding and fine-tune the next treatment, so results keep building year after year.
Why Feeding the Soil Works Better
Synthetic fertilizers act like a sugar rush for grass. They push fast green growth on top, then fade, and do little for the soil underneath. Over time the soil gets more compacted and less alive, and the lawn needs more and more inputs just to look the same.
Organic fertilization works the other way around. Organic matter and beneficial microbes, including mycorrhizae, help break down thatch, recycle nutrients, and improve how roots take in water. The result is a lawn with deeper roots that holds up better against weeds, pests, and drought, and keeps getting better each season. Pair it with natural weed control and core aeration for the full soil-first program.

★★★★★
Exceptional service, great results, and organic fertilization without the harsh chemicals giving us peace of mind with kids and pets while actually building the health of our soil making for a healthier lawn.
★★★★★
Every year for the past 8 or so, our lawn would green up in spring, look lush and gorgeous until June and then slowly start dying out due to fungus. From the first treatment, our lawn has looked beautiful and with every treatment since, it is thicker, greener and healthier than it has been in years.

The effectiveness of their lawn care products is remarkable, and one can see visible and immediate results after just a few treatments. Joseph, the business owner, is an exceptional professional who possesses extensive knowledge about his products and offers his services at a fair price.

Frequently Asked Questions About Organic Lawn Fertilization
What is organic lawn fertilization?
It’s feeding your lawn with natural, organic nutrients and soil builders instead of synthetic fertilizers. Rather than pushing quick top growth, organic fertilization improves the soil itself, so grass grows deeper roots and stays thick and green with fewer inputs over time.
How is organic fertilizer different from synthetic fertilizer?
Synthetic fertilizer feeds the grass directly with fast-release salts, giving a quick green-up that fades. Organic fertilizer feeds the soil, releasing nutrients slowly while adding organic matter and supporting beneficial microbes. The result builds season after season instead of starting over every few weeks.
Is your organic fertilizer pet-friendly and kid-friendly?
Yes. We use organic fertilizers and soil builders with no synthetic fertilizers or harsh chemicals, chosen with kids, pets, and pollinators in mind. As with any lawn treatment, we recommend keeping kids and pets off the grass until the product has been watered in or dried.
How long does organic fertilization take to work?
You’ll usually see color and density improve over the first few treatments, with the biggest gains over a full season. Because organic fertilization rebuilds the soil, results keep improving year after year instead of resetting.
How many fertilization treatments will my lawn need?
Most programs include several treatments a year, timed to your grass’s growing season. The exact number depends on your climate and grass type, so your local team will build the schedule for your area.
What’s in your organic fertilizer?
Our custom organic fertilizers and soil builders were developed with Colorado State University turf and soil scientists and blend natural nutrients with ingredients that improve soil structure and fertility. Ask your local team for the full ingredient details for your program.
Will organic fertilizer burn my lawn?
It’s very unlikely. Organic fertilizers release nutrients slowly, so they’re far less likely to burn grass than quick-release synthetic fertilizers, and we time applications to your grass’s growth cycle.
Does organic fertilization help with weeds?
Yes, over time. A thick, well-fed lawn leaves weeds little room to grow, so fertilization is the foundation of weed control. For weeds that are already there, we pair it with natural weed control using Moose Juice, our plant-based blend.
