Here are 2 options for natural weedkillers. Should I use them?

Weed growth can be a common problem in most gardens. Plenty of products claim to be the most effective weedkillers on the market – including some you might have in the cupboard already.

 

Vinegar and salt are often used to kill weeds. They’re cheap to buy and easy to find in shops. But they might not be the healthiest product for your garden. And in using them, you could cause long-term damage. Here’s why:

Vinegar

Different vinegars contain different levels of acidity. This acidity determines how effective the vinegar is as a weedkiller. Standard dressing vinegar contains 5% acidity – strong enough to damage the upper leaves of the weeds. But this isn’t strong enough to destroy the roots and prevent weeds from growing back.

Horticultural vinegar contains 20% acid – meaning it can kill the upper leaves and the roots of the weeds. However, this much acidity can damage the surrounding areas, including stonework, drainage, and pipes. It can also burn the skin and eyes if you don’t apply it carefully.

 

Salt

Salt dissolved in water is effective as a weedkiller – it dehydrates the plants. But that means it can also kill any plants or vegetation around the weeds, too. And once the salt is in the soil, it can take up to two years to flush away.

Vinegar and salt can work as weedkillers. But we generally wouldn’t recommend you use them. They aren’t always effective at preventing regrowth -  and they can often do more damage than good.

We’d always recommend using specialist products to kill weeds safely and effectively. Make sure to read the instructions carefully, especially in areas used by children and pets.
