Starting an organic first lawn care routine can be as simple as switching to natural fertilizers. Organic fertilizers like compost, manure, and fish emulsion are rich in nutrients and can improve soil structure.
Using chemical-based fertilizers can harm beneficial microorganisms in the soil, which are essential for a healthy lawn. These microorganisms help break down organic matter and make nutrients available to plants.
A well-maintained lawn with a diverse population of beneficial microorganisms will require less water and maintenance. This is because the microorganisms help the soil retain moisture and suppress weeds and diseases.
By adopting an organic first lawn care approach, you can enjoy a healthier, more sustainable yard that's better for the environment and your family.

Transitioning to Organic Lawn Care
Making the switch to organic lawn care can be a game-changer for the health of your lawn and the environment.
First, you'll want to stop using synthetic fertilizers, which can pollute soil and water. According to the article, these chemicals can also harm beneficial microbes in the soil.
On a similar theme: Lawn Care Compacted Soil
Start by testing your soil to determine its pH level and nutrient content, as this will help you choose the right organic amendments. This is a crucial step in creating a balanced ecosystem.
Using compost is a great way to add nutrients to your soil without harming the environment. Compost is rich in beneficial microbes that help break down organic matter.
You can make your own compost at home by collecting kitchen scraps and yard waste, or purchase it from a local supplier. This will save you money and reduce your carbon footprint.
As you transition to organic lawn care, you may notice a slight decrease in lawn growth at first, but this is a normal process. This is due to the soil adjusting to the new nutrient sources.
Regular aeration and dethatching can help improve soil drainage and reduce the need for chemical herbicides. This will also promote healthy grass growth.

Understanding Your Lawn
Tall and durable grasses with deep roots are generally the best choice for organic lawn care. They can thrive in areas where softer grasses wouldn't.
Some grasses don't stand up to weeds as well and require more maintenance. In contrast, taller blades of grass will shade and out-compete weeds vying for the same space.
Organically managed lawns tend to have more vigorous turf with deeper roots and fewer weeds. This is because they're allowed to grow to their preferred height, which promotes better soil health and water retention.
Type of Grass
Fine fescue grows well in acidic poor soil, making it a great option for shady areas.
Tall fescue is actually a superior choice for shade, outperforming fine fescue in many ways.
Fine fescue has low nitrogen needs and a low thatching potential, making it a low-maintenance option.
Some grasses, like fine fescue, can thrive in areas where they normally wouldn't with the help of synthetic products.
For more insights, see: Fescue Lawn Care Calendar
Kentucky bluegrass can be mixed with fine fescue to create a durable and shade-tolerant lawn.
Tall and durable grasses with deep roots are generally the best choice for organic lawn care.
Soft grasses, on the other hand, can be more challenging to grow organically and may not stand up as well to weeds.
The pH Balance
The pH balance of your lawn is a crucial factor to consider when it comes to its overall health. You'll want to do a soil test to check its pH balance, which will tell you how acidic or alkaline it is.
You can test your soil using a reliable do-it-yourself test, consulting with a professional lawn care service, or requesting a soil test from your local Cooperative Extension Services office. This will give you a clear understanding of your lawn's pH level.
The ideal pH for lawn grass is around 6.5, but don't worry if your test results show a different number. If the pH is below 6.0, you can use lime or wood ash as soil amendments to bring down the acidity.
Certain weeds can indicate certain things about the health of your soil. For example, birdsfoot trefoil grows in low-nitrogen soil, while hop clover grows in alkaline soil. Identifying weeds can teach you a lot about your yard.
If the pH is above 7, you can add sulfur to make the soil more acidic. This can help create an environment that's not conducive to the growth of certain weeds.
Here's a quick summary of what you can do based on your soil's pH level:
- Below 6.0: Add lime or wood ash to bring down acidity
- Above 7: Add sulfur to make the soil more acidic
Mow Less, Water Less
You can let your grass grow to its preferred height to promote more vigorous turf with deeper roots and fewer weeds. This height will shade and out-compete weeds vying for the same space.
By allowing your grass to grow taller, you'll end up with a lush, green lawn that requires periodic mowing, but not too much.
In fact, mowing your lawn less often will result in deeper roots and better water retention capacity. This is because the grass is able to spread out and compete with weeds more effectively.
Better soil health promotes deeper roots and better water retention capacity, making your lawn more drought-tolerant and requiring less supplemental irrigation.

Thatch
Thatch is a layer of dead and decaying plant material that can build up on your lawn. This problem is relatively rare in fescue lawns.
Fescue lawns tend to have lower thatch issues because they receive beneficial inputs that stimulate soil organisms. These organisms help control thatch by consuming it as fast as it's created.
Compost and organic fertilizers are great for promoting healthy soil, which in turn helps reduce thatch. This is especially true for lawns that are low-maintenance or maintained using organic methods.
Kentucky bluegrass and zoysiagrass are more prone to thatch development, so it's essential to monitor these lawns closely. Annual evaluations can help you catch thatch issues before they become a problem.
Fertility
Fertility is a crucial aspect of maintaining a healthy lawn. You can keep your lawn green naturally without using concentrated synthetic fertilizers.
One way to nourish your grass is by using organic fertilizers, which are a great alternative to synthetic options. Corn gluten-based organic products offer some preemergence weed control for annual weeds, but be sure to purchase products in a granular formulation for easier spreading.
The application schedule for organic fertilizers varies depending on the type of grass you have. For cool-season grasses, the most beneficial program involves applying corn gluten in early April, late June, and mid-September.
Here's a breakdown of the application schedule for cool-season grasses:
For warm-season grasses, the most beneficial program involves applying corn gluten in mid-April, late June, and mid-August. The application schedule is similar to that for cool-season grasses, but with slightly different rates and timing.
Lawn Care Practices
To keep your lawn looking its best and reduce weed problems, it's essential to employ sound cultural practices. Mowing at 2.5 to 3 inches for cool-season grasses will keep your lawn dense and discourage weed seed germination.
Frequent mowing will also prevent or reduce seed production in some weed species. This is because the growing point for grass is near the crown, while the growing point for many weeds is near the top of the plant.
Suggestion: Push Mower Patterns
To promote healthy root growth and prevent weed seed germination, it's best to water your lawn deeply but infrequently. This will encourage your grass to develop a strong root system that can outcompete weeds.
Here are some key lawn care practices to keep in mind:
- Mow at 2.5 to 3 inches for cool-season grasses.
- Fertilize more heavily in fall and keep fertility levels up in late spring and summer using slow release products.
- Water deeply but infrequently to promote healthy root growth.
- Renovate chronically thin lawns to regionally adapted species and cultivars in the fall.
- Use organic-based herbicides such as corn gluten or herbicidal soaps as needed.
Irrigation
Irrigation can be a delicate matter for lawn care. Too much water and you'll be inviting fungal diseases to take over, while too little water will leave your lawn weak and vulnerable to death.
Turf-type tall fescue is the most drought-tolerant of the four species of turfgrasses, so it's often not necessary to irrigate it. However, fine fescue, Kentucky bluegrass, and perennial ryegrass will need regular watering to stay green during hot, dry weather.
If you do need to irrigate, aim to apply 1 inch of water weekly or enough to wet the top 6 to 8 inches of soil. You can measure rainfall and applied water with a rain gauge to ensure you're not over- or under-watering.
It's also essential to check the soil with a trowel or spade to see if the water has penetrated to the depth of the roots. Early morning irrigation is best to minimize water loss from evaporation as temperatures rise later in the day.
If you're dealing with Kentucky bluegrass, be aware that irrigating in mid-summer (July) can contribute to grub problems. This is because July is the egg-laying period for most Ohio grubs, and moist soil will allow their eggs to survive.
Here's a quick rundown of the drought tolerance of the four species of turfgrasses:
Keep in mind that even dormant lawns may need some irrigation during severe, prolonged drought conditions to survive. Apply one-half inch of water every four to six weeks to keep the crowns and roots alive.
Nitrogen
Nitrogen is a crucial element for plant growth, and without it, plants can't make amino acids, proteins, enzymes, chlorophyll, or nucleic acids.
Plants use nitrogen for many functions, and applying the correct amount is almost impossible to determine because a plant's daily needs fluctuate.
Nitrogen availability can cause plants to elongate their roots if it's inadequate, or absorb too much and lead to excess succulent growth that increases the potential for disease and insects if it's excessive.
In a balanced soil, mechanisms exist to buffer and regulate the amount of nitrogen available to plants.
Applying compost or natural organic fertilizers can complement the functions of soil organisms and regulate nitrogen availability.
Natural Weed Prevention
Natural weed prevention is a crucial part of organic lawn care. You can use corn gluten meal to prevent weeds from germinating in the first place.
Corn gluten is a natural pre-emergent herbicide that can prevent crabgrass seeds from germinating if applied in the early spring. It's a byproduct of corn syrup production and contains 10 percent nitrogen by weight.
Applying corn gluten at the rate of 20 pounds per 1,000 square feet can provide 2 pounds of actual nitrogen, which also has a slow-release fertilizing effect. This can lead to 50 to 60 percent weed control in the first year.

Herbicidal Soaps
Herbicidal soaps can be a good option for controlling annual weeds like common chickweed, spotted spurge, and crabgrass.
They work by disrupting cellular structure and causing dehydration, leading to the eventual death of the plant. This is because they can penetrate green plant tissue and are highly refined.
Herbicidal soaps are non-selective, meaning they can affect desirable plants as well as weeds. This makes them less effective on grasses and larger tap-rooted weeds.
They won't affect underground plant parts, so perennial weeds with extensive root systems may regenerate from their roots.
Natural Weed Prevention
Natural weed prevention is a great way to keep your lawn looking its best without relying on harsh chemicals. You can use corn gluten meal for natural weed prevention.
Corn gluten is a natural pre-emergent herbicide that can prevent crabgrass seeds from germinating if you use it in the early spring. It's a byproduct of corn syrup production.
Research shows that corn gluten is an effective pre-emergent herbicide that can control a variety of weeds, including crabgrass, barnyardgrass, foxtails, dandelion, lambsquarter, pigweed, purslane, and smartweed. The proteins in corn gluten act on germinating seeds to inhibit root growth.

After application and a period of water stress, weed seedlings wilt and die. Corn gluten also contains 10 percent nitrogen by weight, and has a slow-release fertilizing effect when applied to home lawns.
You can achieve 50 to 60 percent weed control in the first year by applying corn gluten at 20 pounds per 1,000 square feet. This percentage increases to 80 to 85 percent in the second year and over 90 percent control by the third year.
The best time to apply corn gluten is shortly after the last spring frost and again in the fall. Water following the application if there is no rain, then allow the area to dry for two or three days.
Lawn Maintenance
Lawn maintenance is crucial for a healthy and weed-free lawn. Overseeding is a technique that replenishes desirable turfgrass and produces a denser lawn that out-competes weeds.
To overseed effectively, use a slice-seeder to deposit grass seed into shallow slits in the soil, ensuring good seed-to-soil contact for high germination rates. Simply scattering seed on the lawn with no cultivation is ineffective and not recommended.
The same times recommended for seeding a new lawn are suitable for overseeding. Mow the lawn short at 1 to 2 inches, then core aerate, before depositing seed at a rate of 1.5 times the amount recommended on the package. Top-dress the lawn with compost to lightly cover the seed and water well.
Common lawn weeds include annuals like crabgrass and annual bluegrass, and perennials like dandelion and plantains. Weeds often thrive under conditions that turfgrasses cannot tolerate, such as heat-stressed and compacted soil sites.
In an organically managed lawn, you may need to rethink your definition of weeds. Consider leaving clover in the lawn as a desirable species, as it can convert nitrogen in the atmosphere into a useable form that provides nutrients for the lawn.
Overseeding
Overseeding is a technique that replenishes desirable turfgrass and produces a denser lawn that will out-compete weeds.
It's not a technique that needs to be done annually, but rather when the lawn quality begins to deteriorate due to drought, insect, or disease injury.
To overseed effectively, match species and cultivars to the turfgrass(es) currently in the lawn to achieve a uniform appearance.
Using a slice-seeder is recommended, as it makes shallow slits in the soil and deposits grass seed into them, ensuring good seed-to-soil contact for high germination rates.
Scattering seed on the lawn with no cultivation is ineffective and not recommended.
Overseeding is done at the same times recommended for seeding a new lawn, and the process involves mowing the lawn short at 1 to 1.5 inches, then core aerating.
A slice-seeder then deposits seed at the rate of 1.5 times the amount of seed recommended on the package.
Sowing heavily ensures good germination rates under less than ideal conditions.
After the seed is deposited, the lawn is top-dressed with compost to lightly cover the seed, and then watered well.
Return the mowing height to normal, and discourage foot traffic at this stage.
After the initial soaking, watering is done frequently and lightly to keep seed moist until it germinates.
Once most of the seed has germinated, the lawn can be watered at a normal maintenance rate if rainfall is insufficient.

Yard Cleanup
Leaf removal is a crucial part of yard cleanup. Dry leaves can be chopped finely by running a mulching mower over them, making them easier to recycle into the lawn.
Recycling tree leaves on a lawn won't increase thatch build-up, as research from Michigan State University has shown. This means you can safely chop and spread leaves over your lawn without worrying about harming your grass.
A stiff rake and some elbow grease can help you prep the lawn surface for spring. Collecting weeds, leaf debris, and thatch will make it easier to add soil amendments and get them working their way into the soil.
Composting is a great way to break down organic matter and enrich your soil. Add collected debris from yard cleanup to your compost pile and you'll be creating a nutrient-rich soil amendment in no time.
Top 5 Tips and Maintenance
Maintaining a lush and healthy lawn requires regular attention to its needs.
First, mow your lawn at the right height. For cool-season grasses, keep it between 2.5 and 3 inches tall. For warm-season grasses, keep it between 1 and 2 inches tall. This will encourage deep root growth and prevent weed invasion.
Watering is also crucial. Aim to provide about 1 inch of water per week, either through rainfall or irrigation. Overwatering can lead to shallow roots and other problems.
Fertilizing your lawn is essential for its overall health. A balanced fertilizer with a 10-10-10 nitrogen-phosphorus-potassium ratio will provide your lawn with the nutrients it needs to thrive.
Regular aeration can also help improve soil drainage and reduce soil compaction. This is especially important for lawns with heavy foot traffic or in areas with poor soil quality.
Aeration
Aeration is a practice of pulling soil plugs to open the soil surface for better movement of air, water, and nutrients.
It's a game-changer for reducing compaction and thatch, especially on tightly compacted clay soils that may need aeration twice a year initially.
A different take: Lawn Care Aeration
Aeration is also essential before fall overseeding, as it helps ensure better seed/soil contact for improved germination.
You can rent aeration equipment at local stores or hire a lawn care provider to do the job for you.
A machine that pulls a half-inch-diameter plug 3 to 4 inches deep on 4-inch centers will do an excellent job.
Not all machines will meet these specifications, but any amount of aeration is better than no aeration to kick off fall fertilization and overseeding.
After several years of natural lawn care, it's usually sufficient to aerate the soil once a year, typically in September.
Aeration on the right schedule, such as in March and September initially, can make a big difference in the density and color of your lawn.

Organic Lawn Care Methods
Organic lawn care methods are a great way to keep your lawn healthy and thriving without harming the environment. You can start by using organic fertilizers that are safe for pets and people, and follow the instructions on the label to learn when and how to apply them.
Organic fertilizers often provide additional nutrients that help other organisms create a strong local habitat under your lawn. This is especially true if you use ingredients like bone meal, feather meal, or seaweed.
Compost is another great way to give your lawn extra nutrients. Just be sure to use a half-inch layer or less at a time, and choose compost that doesn't already contain weeds or weed seeds.
With the right grass growing in the right soil, you can focus on nourishing your lawn naturally. Concentrated synthetic fertilizers are not necessary to keep your lawn green and healthy.
Pest and Disease Control
Pest and disease control is a crucial aspect of organic first lawn care. Most turfgrass pest problems can be controlled by selecting resistant varieties of turfgrass species, following best management practices, and maintaining a healthy, balanced soil.
Proper turfgrass species and cultivar selection is key to reducing insect pests in lawns. Many cultivars of perennial ryegrass, turf-type tall fescue, and fine fescue contain symbiotic fungi called endophytes, which are toxic to sod webworms, chinch bugs, and billbugs.
Reducing thatch development or removing existing thatch can also help eliminate shelter and food for some insects. Higher mowing heights often shade sun-loving chinch bugs or billbugs, as well as raise humidity so that insect diseases may become prevalent.
Here's a list of botanical and biological controls for certain turfgrass insects:
Using Synthetic Chemicals in Gardening
Using synthetic chemicals in gardening can have serious consequences for both humans and the environment.
Synthetic lawn fertilizers are salt-based and can literally burn your grass if used in excess.
Even when used as directed, the chemical buildup in the soil can harm or even destroy the living organisms that Mother Nature has placed there for long-term benefits.
Chemicals used in lawn care products can pose a danger both to humans and the environment.
A recent study found a compelling link between exposures to glyphosate-based herbicides and increased risk for non-Hodgkin lymphoma.
Synthetic chemicals like those in Roundup can still pose a risk even with proper precautions.
The environmental and potential health risks associated with using synthetic chemicals in gardening are significant.

Pest and Disease Management
Pest and Disease Management is a crucial aspect of maintaining a healthy lawn. Over 90 percent of the world's arthropods have a neutral or beneficial effect on human activities, and in turf, that percentage is even higher.
Turfgrass pests occur for a reason, often related to a weakness in the turfgrass plant or some deficiency in the soil. Identification is the first step in pest management, but instead of looking for how to control the pest immediately, ask "Why is it there?" Most turfgrass pest problems can be controlled by selecting resistant varieties of turfgrass species, following best management practices, and maintaining a healthy, balanced soil.
Healthy turf and plants can tolerate higher numbers of damaging insects or simply outgrow whatever damage is incurred. A recurring theme throughout this publication is the need for a balanced soil and healthy plants.
Insects and other invertebrate pests that damage turf generally fall into one of four categories: root feeders, stem burrowers, sucking-type insects, and leaf eaters. Root feeders include white grubs, ground pearls, nematodes, and mole crickets.

Here are some botanical and biological controls for certain turfgrass insects:
- Armyworms: Endophyte-enhanced turfgrasses, neem, Bacillus thuringiensis bacterium, Steinerema sp. nematodes
- Billbugs: Neem
- Chinch bugs: Flood area with water, neem
- Cutworms: Endophytes, Bacillus thuringiensis bacterium, Steinerema sp. nematodes
- Sod webworms: Endophyte enhanced turfgrasses, flood area with water and mild detergents, neem, Bacillus thuringiensis bacterium, Steinerema sp. nematodes
- White grubs: Beauveria bassiana fungus, neem, garlic juice, capsaicin extracts, cedar oil, milky spore disease by Bacillus popillaie or Bacillus lentimorbus, Steinerema sp. nematodes, Heterorhabditis sp. nematodes
Proper turfgrass species and cultivar selection is key to reducing insect pests in lawns. Many cultivars of perennial ryegrass, turf-type tall fescue, and fine fescue contain symbiotic fungi called endophytes, which are toxic to sod webworms, chinch bugs, and billbugs that feed on them.
Herbicide Products
If you're looking for a more natural approach to lawn care, consider using organic herbicides. Chelated iron is an active ingredient in some products, like Fiesta, that can help control broadleaf weeds in your lawn.
Using organic herbicides can be a great alternative to traditional chemical-based products. They're often safer for the environment and can be just as effective.
Some organic herbicides contain chelated iron, which is a type of iron that's more easily absorbed by plants, making it more effective at killing weeds. This can be especially helpful for lawns with broadleaf weeds.
Fiesta is one example of an organic herbicide product that contains chelated iron. It's a great option for lawns with broadleaf weeds.

Understanding Lawn Biology
A healthy lawn is built from the ground up, literally. Turf is healthiest in a biologically balanced soil – one in which bacteria account for slightly more than half of the biomass.
Bacteria thrive in soils that contain residues high in carbohydrates, such as sugars and starches. Organic fertilizers like vegetable and animal meals and compost made from food waste or manure contain the carbohydrates necessary to sustain a bacteria-dominated soil.
Maintaining a balanced, healthy soil system ensures that essential nutrients are used efficiently.
What Are Endophytes?
Endophytes are beneficial symbiotic fungi that live between the cells of certain plants, mainly in the leaves. They produce chemicals toxic to insects like sod webworms, chinch bugs, and billbugs.
Certain cultivars of perennial ryegrass, turf-type tall fescues, and fine fescues contain these endophytes. These plants can be labeled as "endophyte-enhanced."
Endophytes can be added to existing lawns through a process called slice-seeding. This method was successfully tested in OSU research, resulting in 50 to 60 percent of the lawn containing the endophyte after two years.
If you're considering using endophyte-enhanced grass for pasturing, be aware that it may be injurious to grazing animals.
