How to Kill Weeds Naturally

Below we’ll recommend a handful of ways you can control and treat weeds naturally in your lawn and landscaping.

Weeding Supplies Needed

  • Consider gardening gloves to keep your hands clean.
  • If treating a large area, consider investing in a gallon sprayer.

Weeding Tools Needed

  • Consider a tough weed barrier for landscaped areas.
  • Choose an effective weeding tool for your needs.

Total Cost: USD 20

Set Aside Some Time

Total Time: 30 minutes

  1. Pull weeds by hand.

    Pulling weeds by hand can be a pain in the rear but it’s a safe way to do it. Consider some great weeding tools.

  2. Use Weed Barrier.

    Using a weed barrier can naturally prevent weeds from coming up in your garden and flower beds naturally.

  3. Mow at a high level.

    By mowing at the highest level, you’ll encourage a dense, lush lawn capable of crowding out the weeds.

  4. Aerate your yard.

    Most experts recommend aerating once each year in the fall.

  5. Dethatch your yard.

    You can improve water and nutrient uptake by dethatching. It is necessary to dethatch when thatch has become so dense that it prevents water and nutrients from penetrating the soil.

  6. Topdress your yard.

    Topdress the lawn with compost. Topdressing is a simple matter of spreading a light layer of organic and well-decomposed compost onto the lawn and raking it in.

  7. Reseed your yard.

    We recommend reseeding bare patches of lawn in the fall, well before frost. Reseeding will give the grass seed a head start for spring, so the patches fill in with grass and aren’t left open to weed seeds.

  8. Water your yard appropriately.

    Water deeply and infrequently: Maintain adequate soil moisture, but do not over-water. Many weeds have shallow roots and grow by frequent watering. 

Results

Following these tips to can help you maintain weed-free landscaping year-round.


What should you look for in a natural organic weed killer or herbicide?

using organic weed killer on lawn
Using organic weed killers on your lawn is safe for pets and wildlife.

1. Effectiveness

You can check the product’s effectiveness, which you intend to buy by looking at the chemicals used in it. After that, you must go for the reviews of the users who have purchased this product. Their positive experiences will compel you to buy this product for your lawn and garden.

2. Water resistance

The natural weed killer you intend to buy for your landscape should be water-resistant during the rainy season. Otherwise, it will wash away with the rain. Several weed killers in the market guarantee water resistance but during the rainy season.

3. Type

There are two types of weed killers in the market, one is a concentrate, and the other is ready to use. When we talk about the concentrates, they are comparatively expensive but can be potent in their performance based on how you dilute them. If you buy a concentrated weed killer, then you have to experiment with it with different concentrations to find the perfect amount that is best for your needs.

4. Safety

When you are shopping for the best weed killer for your lawn management at home, always consider your pets and kids’ safety. You must check the ingredients used in making that product and find the answers to several questions that come to your mind, such as whether or not the weed killer is organic. Are there any chemicals that might harm your children over time?

5. Ease of use

The weed killer you are planning to buy for your lawn should be pretty easy to use. You will notice that most of the weed killers come with complicated instructions, and you need to follow the steps for their preparation and application. It would help if you considered buying a product that is easy to prepare, and everyone quickly understands the instructions.

6. Application coverage

For small areas that need weed treatment, the ready-to-use products are the best choice. When there are incredibly tough weeds or you need to cover a large space, concentrated products will be your best bet.

7. Seasonality

Considering the weather is very important when you will buy a weed killer for your garden or lawn. Some weed killers in the market work for a specific season, and you cannot use them throughout the year. If you buy a weed killer to get rid of weeds that appear in the winter season, it may not be ineffective during the summer season.

Read the label carefully to give you an idea about the season in which the products should be used. Many weed killers, however, can be used all year long.

8. Residual effects

The weed killer you are planning to use on your lawn should not affect the soil. Some products prevent the growth of weeds and get accumulated in the ground, and they affect the pH of the soil badly. When the soil pH is disturbed, then definitely, the productivity of the land is reduced. Ensure the weed killer you want to use for your lawn does not affect your property’s soil because the carcinogenic substances in these weed killers can lead to several soil problems.

9. Amount required

First of all, you have to decide which area you want to treat with the herbicide. If you are treating the weeds for a small space, you can select the ready-to-use herbicide that does not require dilution with water, and it is also economical to buy.

On the other hand, when you have a wide area full of weeds you want to treat, you must go for a concentrated product to make a solution according to your site. You have to calculate the area you want to treat and then decide the weed killer according to your need. There are so many herbicides in the market, but you must read the reviews from the users and then select the one for your garden.

10. Targeted weeds

There are several necessary herbicides, each targeting certain plant pests (weeds, grasses.). A non-selective herbicide tries to kill most plants, while a selective herbicide is designed to kill specific plants, usually grasses or broadleaf weeds.

11. Kid and pet-friendly

If you have little children or pets at home, you must consider their safety as the priority and then select and herbicide for your lawn. The herbicides available in the market contain toxic ingredients that are unsafe for kids and pets. However, the yard is usually safe within hours of application.

12. Price

Most people determine the affordability factor when it comes to buying any weed killer. There are expensive as well as economic weed killer products available in the market. Most of these products come from renowned brands, while others are cheaper. Make sure you look at the effectiveness and coverage area when planning to buy any product. Make sure you go for the work within your range; otherwise, expensive products will increase your lawn maintenance worries.

13. Visible results

It’s important to note that some weed killers give quick results, while others are slow to show their effectiveness. In most cases, weeds will be killed within a day or two. You have to be patient enough and give some time to these products to kill the weeds effectively.
