Weeds are every gardener’s worst enemy, weeding their way through perfectly planted gardens and causing all sorts of havoc along the way. So, with summer fast approaching, it’s no wonder gardeners are now trying to make homemade weed killers that get rid of those lingering pests once and for all. Sure, gardeners could go to the store and stock up on chemical-laden weedkiller to kill them, but that’s not the safest option. The gardening experts at Happy DIY Home have shared a few ways gardeners can make their own natural weed killers.
The first method suggested was to use lemons to rid gardens and patios of troublesome weeds.
Experts explained, “Lemons contain high amounts of citric acid, which is great for burning unwanted weeds.
“Just squeeze as much fresh lemon juice into a spray bottle and spray the homemade weed killer on the offending plants.
“They should shrivel up and die within a day or two.
“For best results, wait for a hot, dry day to drizzle your weeds with lemon juice.”

Lemons can be purchased from Asda for 54p for a pack of four, which works out to less than 14p per lemon.
If gardeners don’t have fresh lemons on hand, or just don’t have time to squeeze them, store-bought lemon juice will work just as well.
Lemon juice should work well on its own, but if gardeners aren’t getting the results they want, try mixing it with white vinegar, according to gardening pros.
They suggested, “Four ounces (113ml) of lemon juice mixed with a liter (about 1 liter) of white vinegar can be a powerful homemade weedkiller.”
Be warned, however, that while not toxic, this highly acidic homemade weed killer solution can still sting if it comes into contact with the eyes, so it is advisable to wear safety goggles.

Another solution is to mix salt and vinegar as this creates a powerful and long-lasting natural herbicide, experts say.
Individually, salt and vinegar are known to be powerful natural weed killers.
Gardening experts explained, “One of the few weed killers that goes directly into the root system, pure salt is a homemade weed killer that will starve the leaves and roots of moisture and dehydrate them.
“For small patches of weeds, you can add salt directly to the plants and the soil.
“For large areas, consider mixing salt and water in a spray bottle and spraying on the weeds. Note that this will also kill the grass.
Gardeners can also use vinegar in the same way, but note that only vinegar containing at least 5% acetic acid will work, so standard white vinegar will work well.
Experts continued: “That said, the most effective approach is to mix the two together in a much stronger homemade weedkiller solution.
“Mix a gallon of five percent white vinegar with a cup of table salt in a bucket and stir until the salt dissolves completely.
“Then add two tablespoons of dish soap and stir thoroughly.
“The liquid soap will act as a surfactant to ensure your solution sticks to the weeds.
“Once that’s done, use the funnel to pour your weed killer into a spray bottle and spray it onto your weeds, making sure to coat all surfaces thoroughly.”
When it comes to alternatives to natural weed killers, they don’t get much simpler or cheaper than this – boiling water.
To perform this trick, fill a kettle or saucepan with water, bring it to a boil, and pour the boiling water over the weeds.
Unfortunately, boiling water isn’t a permanent solution, experts say.
They said: “Although boiling water works remarkably well to kill foliage, it does not affect the root system, so weeds will eventually regrow.”
That said, boiling water proves to be a great way to temporarily get rid of those weeds growing between cracks in driveways or sidewalks until gardeners have time to find a more homemade weedkiller solution. long term.
