Removing weeds from your lawn is important not only for aesthetics, but also for the health of your grass. Common weeds like dandelions, thistle, and crabgrass can create a competition for valuable resources such as sunlight, nutrients, and water. As weeds steal these resources, your grass gets weaker, making it easier for weeds to completely overtake your property.

How to kill weeds naturally

The only way to kill weeds without any products is to pull them up by hand, which can be hard work. You have to grasp the base of the plant and pull its roots out completely to ensure it will not return. 

Other natural ways to kill or prevent weeds include:

  • Corn gluten—It dries out the initial roots of emerging plants, killing weeds before they take over.
  • Mulch—Mulch prevents sunlight from reaching weed seeds, smothering them and preventing them from sprouting.
  • Healthy grass—Healthy, dense grass is less susceptible to weeds that need space and sunlight to grow.
  • Limiting your digging—Dig only where you need because soil, grass, and other plants are potentially obstructing hidden weed seeds.

Does vinegar kill weeds

Vinegar-based pesticides can be effective against weeds; however, store-bought vinegar is not powerful enough to have an effect. Horticultural vinegar pesticides contain at least 20% acetic acid, while grocery store products only have 5%. This stronger concentration can kill weeds in as little as 24 hours, but it only eliminates above-ground growth. The root system is left unaffected, allowing weeds to grow back. Vinegar is also non-selective, meaning it will harm your grass, flower, shrubs, and trees if they are accidentally sprayed.

Does salt water kill weeds

Salt water does kill weeds, and it does this by traveling up through their roots and dehydrating the plant as it is absorbed. Like vinegar, salt water is also non-selective, which means it will harm all the plants it comes into contact with. To effectively use salt water as an herbicide, use a 3:1 mixture of water to salt and use a funnel to pour it directly on each weed, then water the surrounding plants to mitigate damage.

Salt water should be used sparingly in your lawn, as salt is not biodegradable. Instead of breaking down, salt builds up in soil and can change the pH, eventually eliminating necessary nutrients from the soil and making it impossible for anything to grow. 

What kills weeds permanently

To kill weeds permanently, you have to eliminate every part of them—leaves, stems, and especially the roots. While brown, wilting leaves may make it seem like a weed is dead, it will still come back unless the roots are killed as well. Some DIY options can kill weeds permanently, but they can be dangerous to you and the environment if used incorrectly. Herbicides are the best option to get rid of weeds, and are safest when applied by lawn care professionals.

How to prevent weeds

Keeping your lawn thick and healthy will keep the weeds from overrunning your lawn, meaning that professional lawn care is the best way to prevent weeds in the first place. Although weeds can grow in any soil, soil improvements can help level the playing field between the plants you want and the weeds you don’t.

Add plants and ornamentals to your landscape

Adding ground cover plants is a great method for crowding out weeds in decorative garden beds. Essentially, weeds take advantage of open areas and available resources; eliminate these, and you’re well on your way to preventing weeds.

Ensure your grass is rich in nutrients

You can make sure that your existing plants are weed-free by keeping them healthy—aerated soil that is well-drained will ensure this happens, especially when followed up by seeding services. You can also test your soil to develop an optimal fertilization plan. 

Use organic mulch for garden beds

Mulch is probably the most important factor in controlling weeds. Bark and other decorative mulches work to prevent weed growth by blocking light. Most professionals agree that organic mulches are the way to go. These types of mulch help improve soil structure and add nutrients to the soil. Mulch can also keep the soil cool and reduce water loss due to evaporation!

Are weeds out of control in your yard or garden?

Sometimes, no matter how hard you try to keep weeds out of the garden on your own, they’re going to grow. While you can always try DIY weed control, the best way to ensure a weed-free yard or garden is with our organic weed elimination service

At Blades of Green, we have worked hard to design and perfect a powerful weed control program. Our process is both safe and effective, so you don’t have to worry about harmful runoff or negative effects on your grass. We begin with a pre-emergent solution that treats seeds, preventing weeds from growing in the first place. That treatment is followed by monthly visits from April to October with a post-emergent herbicide that targets weeds specifically, keeping your grass and ornamental plants untouched.
