Organic weed and feed options for a chemical-free lawn care routine
Chemical lawn products are dangerous for kids, pets, and the environment, which is why so many people want to avoid them. Chemicals can drain into nearby rivers and lakes and damage fish and plants. They can also lead to skin problems or other health issues in people and animals.
Organic weed and feed from natural ingredients are eco-friendly lawn care products. They sustain the grass and control weeds, all at once. In contrast to chemical weed and feed products, organic weed and feed products use things like corn gluten meal, compost, seaweed or a natural vinegar or citrus oil spray. These soil products also improve soil conditions and promote better growth of the grass while suppressing the weeds.
Growcycle provides an extensive selection of products and tools that facilitate organic weed and feed practices, allowing both gardeners and homeowners to cultivate healthy, chemical-free lawns.
Benefits of Organic Weed and Feed
For those who want a good-looking lawn without the harsh chemicals that can leach into the ground and cause all kinds of environmental headaches, organic weed and feed products offer plenty of options. Here are some key benefits:
1. Safe for Kids and Pets
Safety is one of the primary benefits of organic weed and feed. Since they don’t use synthetic chemicals, these products are much safer for pets and children who play on the lawn. So, no need to worry about harmful substances getting on skin or paws.
2. Better for the Environment
Organic products have less impact on the environment. They don’t emit pollutants into the air, water or soil. Unlike chemical weed killers and fertilizers, organic options decompose naturally and are not toxic to insects, animals or neighboring plants.
3. Healthier Soil
Organic weed and feed build the soil health over time. Natural ingredients such as compost or seaweed allow the soil to retain nutrients and moisture. This makes the grass stronger and prevents weeds from growing back.
4. Supports Long-Term Lawn Growth
Unlike chemical fertilizers that give grass a fast boost, natural lawn fertilizer with weed control acts over time, providing gradual benefits. It creates a strong base for long-term health that produces deeper roots and greener grass through the seasons.
5. Reduces Weed Growth Naturally
Organic weed control doesn’t merely eradicate weeds, but it strengthens the lawn to withstand them naturally. Improved soil health and grass health mean weeds have a tougher time finding a place to grow.
6. Encourages Biodiversity
Organic methods encourage earthworms and other good bugs and pollinators (like bees). These useful creatures help keep a garden healthy; fewer chemicals can keep them safe.
7. Fewer Health Risks
With recurring exposure, several chemical products may cause skin irritation, breathing problems, or other health issues. Organic weed and feed eliminates that risk, making it a safer option for anyone with allergies or sensitivities.
How Organic Weed and Feed Works
Without the use of harsh chemicals, organic weed and feed products provide a system of natural improvement of lawn health and weed control. They serve two primary purposes: nourish the grass and prevent weeds from invading. Let’s take a look at how they do it.
Mechanisms of Action
Organic weed and feed products employ one of two primary methods of weed control:
1. Pre-Emergent Control
This technique prevents weed seeds from growing before they even sprout. For this, a common natural ingredient is corn gluten meal. It forms an impermeable layer in the soil that prevents seeds from growing roots down. This way, the weeds never have the opportunity to propagate in the first place.
2. Post-Emergent Control
This is aimed at weeds that are already established. Some organic products employ natural ingredients such as vinegar, clove oil or citrus oil to burn or desiccate the leaves of the weeds. These are environmentally safe, yet potent against unwanted plants.
Key Nutrient Sources
In addition to controlling weeds, organic weed and feed provides grass with the food it needs to become thick and strong. Some of the natural ingredients used to feed lawns are:
- Bone Meal: Enriching source of phosphorus promoting strong roots. It’s made from ground-up animal bones and is super gentle on the soil.
- Feather Meal: High in nitrogen, helps grass to grow green and thick. It's made out of processed feathers and releases nutrients over time.
- Seaweed (Kelp): A powerhouse of micronutrients and hormones that promote root development and stress resilience. It also improves soil health.
- Compost Tea: A liquid produced by soaking compost in water. It’s full of beneficial microbes and nutrients that energize soil and promote healthy grass growth.
Types of Organic Weed and Feed Options
There are several different types of non-toxic weed and feed products available, and they all work in different ways. Some excel at preventing weeds before they sprout, and others help grass thrive, fast. Here’s a look at some of the most common:
1. Corn Gluten Meal
An example of a common organic weed control product is corn gluten meal. It acts as a pre-emergent, meaning that it prevents weed seeds from germinating to begin with. It’s corn-based and safe for people, pets, and the Earth.
When sprayed at the appropriate time, typically early spring, it forms a barrier on the soil that inhibits seeds from growing roots. It doesn’t hurt existing grass or plants.
2. Compost and Manure Based Granulars
These are derived from aged compost or animal manure. They release nutrients slowly that feed the lawn over time and allow it to grow thick and strong.
- Enhance the health and structure of the soil.
- Organic matter helps retain water and nutrients.
- It may help crowd out weeds by making grass more competitive.
3. Liquid Organic Fertilizers
Liquid organic fertilizers consist of natural raw materials such as seaweed (kelp) and fish emulsion. It is sprayed directly on the grass and is readily absorbed.
- Quick-flowing nutrition, helpful during the season of growth.
- Seaweed provides micronutrients and strengthens plant immune responses.
- It is very high in nitrogen and makes grasses green and healthy.
4. Natural Herbicide Blends
These products go after weeds that have already grown. They use things like vinegar, citrus oil or fatty acids to naturally damage or dry out weeds.
- These sprays work by breaking down the outer layer of the weed, leading it to dry up.
- Pre-emergent herbicides work best on young, small weeds.
- Safe for people and pets when used as directed.
Choosing the Right Products
Not all organic weed and feed products are equal. Some are tougher, safer or more budget friendly than others. For optimal results, products must be selected based on the lawn’s requirements and the homeowner’s goals. Here’s how to make an informed choice:
1. Certification & Labeling
When purchasing organic products, it is recommended to find labels of trust so that the product is truly organic and safe.
- OMRI-listed: This means that the product is approved by the Organic Materials Review Institute. If it’s OMRI-listed, that means it meets organic farming standards and is free of harmful chemicals.
- “Pet-Safe” Labels: A lot of individual products have the label pet safe weed and feed. These labels provide additional reassurance, particularly for families with children or pets that run around on the lawn.
2. Reading Ingredient Lists
Knowing what’s in the product matters. Here’s what to watch for and what to skip:
Look for
- Compost, kelp, bone meal, feather meal, corn gluten meal or fish emulsion.
- Oils from plants, such as clove oil, citrus oil, or neem oil.
- Products with clear labels/ what they do (pre-emergent, post-emergent, fertilizer)
Avoid
- Products that do not clearly list out their ingredients
- Terms such as “synthetic,” “quick-release chemical,” or unfamiliar additives.
- If a name sounds harsh, chemical even, rather than covering up nature, it will be avoided.
DIY Organic Weed and Feed Recipes
Making organic weed and feed solutions at home can be a great option for those who enjoy a hands on approach or want to save some money. This is where three easy DIY recipes come into play:
1. Vinegar + Dish Soap Herbicide
This homemade weed killer is effective at killing small, young weeds that have already germinated.
Ingredients
- 1 gallon of white vinegar (5% acidity)
- 1 tablespoon of liquid dish soap
- (Optional) 1 tablespoon of salt for extra strength
How to Make It
- Combine the vinegar and dish soap (and salt, if you’re using it) in a large spray bottle or garden sprayer.
- Shake well to combine.
- On a sunny day, spray directly on the leaves of unwanted weeds.
Not only does this kill weeds, but it is also harmful to grass or flowers. Just apply it directly on the weeds, not on the lawn around them. Wear gloves and avoid contact with eyes or skin.
2. Homemade Compost Tea
Compost tea is a liquid, homemade natural lawn fertilizer with weed control made by soaking compost in water. It’s rich with healthy microbes and nutrients that contribute to strong and healthy grass.
Ingredients
- A bucket (5 gallons)
- Shovel-full of compost (homemade or store-bought)
- Water (non-chlorinated if possible)
- Stirring stick or aeration pump (optional)
How to Make It
- Fill the bucket halfway with compost.
- Fill the remainder of the bucket with water.
- Mix well and allow to set for 24 to 48 hours.
- Strain with an old cloth or mesh to get solids out.
Use a watering can or garden sprayer to pour or spray the compost tea onto the lawn. Apply in the early morning or evening to prevent burning the grass.
3. Corn Gluten Meal Mix
Corn gluten meal acts as a pre-emergent by preventing seed germination in the soil.
Ingredients
- Corn gluten meal (buy from a garden center or feed store).
How to Use It
- Spread corn gluten meal evenly across the lawn at a rate of 20 pounds per 1,000 square feet.
- Water it lightly, to help it settle into the soil, but not too much, so it won’t properly block weed seeds.
- Do this early in the season before weed seeds start to germinate (typically early spring)
Don’t use before seeding new grass; it may prevent those seeds from germinating. Reapply every spring and fall for best results.
Application Timing & Techniques
Using non-toxic weed and feed at the right time and the right way makes all the difference. Here’s a quick guide on when and how to use these products for the most effective results.
1. Spring Pre-Emergent Window
Prime pre-emergent products, such as corn gluten meal, prevent weed seeds from germinating. But they are effective only when applied before weed seeds have begun to germinate.
- The best time is early spring, when the soil has recently warmed and the soil temperature is about 55ºF (13ºC).
- This occurs in most regions between mid-March and early April, but can differ by region.
Use a soil thermometer or consult a local gardening guide to monitor the right time to apply.
2. Summer/Fall Post-Emergent
Post-emergent products are used once weeds have already emerged. They're most effective on common broadleaf weeds like dandelions or clover.
- Summer and fall are best, when weeds are actively growing.
- be cautious when using on Bermuda, Zoysia and other grass types. Use organic sprays that are grass-safe but tough on weeds.
- Re-application may be required every few weeks until the weeds die out.
3. Proper Watering & Mowing After Treatment
Results can then be dependent on how and when to water or mow after using an organic weed and feed product.
- For granular products (corn gluten meal, for example), water lightly after spreading to activate them, but do not soak.
- If using liquid sprays, don’t water for 24 to 48 hours, so the ingredients can be completely absorbed.
- Don’t mow until 2 to 3 days after applying.
- Mow to a slightly higher height; 3 inches is a good length. Tall grass covers the soil, which inhibits weed germination.
4. Equipment & Safety Gear
Having the right tools for the job helps the job go more safely and efficiently.
- Spreaders: Best for dry, granular products. These tools distribute the material across the lawn evenly.
- Sprayers: Best for liquid weed and feed solutions. Use a sprayer or hose-end sprayer to apply for even coverage.
Even if the product is safe, wear gloves and closed-toe shoes while applying.
