Weeding is one of the most dreaded garden tasks. It’s time-consuming, labor-intensive, and often frustrating. Before you reach for that bottle of weed killer, though, there are plenty of organic and natural ways to keep your garden free from intrusive weeds without polluting your soil and harming your other plants.

Here are my favorite safe and organic methods for killing existing weeds, suppressing future growth, and preventing weeds from taking root in your garden in the first place. So, let’s get started!

When the weeds are already a problem: Organic weed killing solutions

Though there’s no foolproof method for eradicating weeds entirely, these organic weed-killing methods (or a combination of all) will help you banish these pesky little invaders from your garden.

Getting down and dirty

The first step to take when dealing with existing weeds is to remove them physically from the soil. This isn’t the easiest or the most glamorous method, but it is often necessary, especially if the weeds have been raging unchecked for a while. If you have a trowel and some gloves, you have everything you need to get started.

Simply dig around the base of the weed to loosen the soil and extract as much of the root system as possible. This technique works best when the soil is moist, so you may want to water your weeds or wait until just after a rainstorm.

Boiling Water

Another method to try is boiling water. This works best with shallow-rooted weeds and won’t work as well for deep, established taproots. Pour boiling water directly onto the weeds you are trying to eliminate. The intense heat will kill them, and they should die within a few days. Just be careful not to spill any boiling water on yourself or nearby plants!

Deadly vinegar bath

Vinegar is a great natural weed killer that can take out even the most stubborn of weeds. Simply pour some white vinegar directly onto the weeds, and you should start seeing results within 24 hours! This method works best in sunny spots where the vinegar can really do its job. You may need to reapply several times before you see permanent death of your unwanted guests. Take care to avoid splashing on any healthy plants.

For an even more powerful solution, mix equal parts warm vinegar, salt, and dish soap in a spray bottle. Spray the mixture directly onto weeds and watch them wither. Be sure to keep an eye on the area and reapply if necessary.

When prevention is key: Organic weed suppression methods

Mulch, mulch, mulch!

Mulch is one of the best ways to suppress weed growth. Mulch acts like a physical barrier between the soil and the sun, preventing weeds from getting enough light to grow. It also helps maintain moisture in the soil, which can help keep weeds from sprouting up (they need damp soil to germinate!).

Look for organic mulches such as bark chips, straw, wood chips, or even hay. Spread the mulch in a thick layer at least three inches and keep it away from your plants’ stems so that they can still get enough sunlight.


Solarization is another excellent method for suppressing weed growth. This technique involves using the sun’s heat to kill off weed seeds and other pests in the soil. To use this method, simply spread a clear plastic tarp over the area where you want to suppress weeds. Anchor it down by putting stones or stakes around its perimeter. The plastic will trap heat and solarize the soil, killing any unwanted weed seeds and preventing them from germinating.

Create a barrier

Use landscape fabric or cardboard to create a barrier between your garden and potential weed-infested areas. This is especially useful if you have weeds spreading from an adjacent bed or area. Use thick fabric or cardboard that won’t allow any light through, and add your garden soil over the top. This method works best if you are putting in a new bed, as it’s more difficult to install in existing areas.

Investing in the future: How to keep weeds from coming back

Keep it clean

Maintaining a weed-free garden requires some effort on your part. Always keep the area around your plants free of weeds by removing them as soon as you see them popping up. The sooner you can remove them, the less room they have to spread their seeds and become an even bigger problem. You should also remove any weeds you have pulled and dispose of them properly. Don’t put them in your compost!

Cut down on watering

Most weeds need plenty of water to thrive, so you can help stifle their growth by reducing the amount of water you give your plants. Try reducing how often and how much you water your garden – this will help keep moisture levels low enough that most weed seeds won’t germinate.

Plant ground cover

Ground cover plants are great for keeping weeds from sprouting up in your garden beds. These low-growing, spreading varieties form a dense mat that can help prevent weeds from getting enough light to grow. Examples of effective ground cover plants include creeping thyme, creeping phlox, and sedum.

Keep the soil healthy

Healthy soil is essential for a weed-free garden. Add compost to your soil yearly to keep it full of nutrients and discourage weed growth. Compost also helps create good drainage, which will help keep the soil dry enough for weeds not to sprout in the first place.

Keeping weeds out of your garden doesn’t have to be a battle!

By using the organic weed-killing and prevention methods outlined above, you can create a weed-free garden without relying on harsh chemicals. The key is to stay vigilant and not let weeds get out of hand! With a bit of work and patience, you’ll be able to enjoy a healthy, beautiful garden all season long.
