Knowing how to kill weeds naturally is important because many weed killing products contain harsh chemicals that can be harmful.
The chemicals in the weed killer can also make their way into the soil. When it rains, the chemicals can be washed away and could make their way into surrounding areas or could even end up in rivers or lakes, polluting the water.
Research published last year also suggests that a common herbicide may be playing a role in rising rates of inflammatory bowel disease in humans. The study,published in自然,suggests that propyzamide, commonly used in agriculture to kill weeds, may increase inflammation in the large and small intestines. So while it's always handy to sometimes be able to use these products, it does make sense to try to cut back as much as possible and look for greener alternatives when dreaming upgarden landscaping ideas.
Read on for the best ways to get rid of weeds in your garden naturally.
How to kill weeds naturally
Organic gardeningemits fewer emissions, uses less energy, and may improve biodiversity. Gardening expert Calum Maddock atHomeHow.co.uk, outlines six ways you cantackle weedswithout resorting to polluting products
1) Pull the weeds out
If you just have a few weeds here and there, you may be able to get rid of all of the weeds by hand. Removing the root is the most important thing to remember when pulling up weeds.
Pull carefully at the base of the weed to make sure it is pulled out completely. If you are pulling up nettles or a weed you do not recognise, always wear gloves when doing so. If you struggle to pull the roots up with just your hands, consider investing in a weed pulling tool like thisinexpensive manual dandelion weeder from Amazonorthis mechanical weed tool by Fiskar, also from Amazon. These can be especially useful when you have a lot of weeds to remove.
Once pulled up, make sure you don't compost any perennial weeds as this can potentially spread more around your garden.
You can see how effective weed pulling tools can be in our article where Garden Ninja explainswhy you should get rid of perennial weeds before scarifying.
2) Use lemons
Simply cut a lemon in half and then squeeze the juice over the weed. The citric acid in the lemon should kill the weed within a few days. This method is especially effective when there is strong sun shining on the weeds. The lemon juice can be used as it is, there is no need to dilute it.
或者,你可以得到一些粉citric acid,like this bucket of citric acid from Amazon, and mix this with water in a spray bottle. Then, simply spray the weeds with the solution.
3) Use salt
Salt can be quite effective at killing weeds. Sprinkle some salt liberally over the weed and leave it there. This should kill off the weed within a few days. Salt is also great for deterring insects and slugs. Be careful not to sprinkle the salt on the surrounding grass or plants as this could kill them off too.

4) Use eco-friendly weed killers

Simply spray the solution directly onto the weed and leave it to do its thing. These eco-friendly weed killers will usually kill off the weeds within a few days.
5) Reach for the vodka
This method works best for weeds that get a lot of sunlight. Create a mixture of 1 part vodka and 2 parts water. Then, add a couple of drops of liquid dish soap to the solution. Spray the solution directly onto the weed and this will dry the weed out and kill it off. Again, avoid the lawn and plants.
6) Mulching
While this won't technically kill weeds, mulching can be an effective prevention technique for weeds in your garden. This is the process of adding a material such as wood chippings over your soil.
Mulching around established plants will suppress new weed growth as well as helping your soil retain moisture in hot weather You can read more on 'what is mulching' in our piece on the topic.
7) Boiling water
And lastly, you can try simply boiling water in the kettle and pouring it on the weed. This will cause the weed to burn and die.It's worth checking outhow much electricity does a kettle useif you plan to use this method regularly.
