Weeds have an outstanding ability to prosper in conditions with little sunlight and abundant moisture. Deposits from rain, dust, bird droppings, and fallen leaves will build up gradually in gravel, providing the perfect environment for weeds to flourish.

Weeds that grow in gravel or patios originate from seeds dispersed by the wind, brought by animals, or unintentionally carried by individuals on their shoes. The growth and spreading of the roots of these seeds is triggered when the conditions are warm, moist, and humid.

Gardening expert and CEO of GreenPal spoke to the Express and he provided his preferred strategy to deal with weeds in gravel, reports. Bryan used his 22 years of experience in landscaping to share different tactics for managing weeds in gravelled areas, which ranged from eco-friendly methods to more forceful ones.

As a natural home remedy, the expert suggests something that is almost entirely free. He said: "One method I've tested out is pouring boiling water on the weeds.

"The hot water burns the weeds and causes them to wilt and die almost immediately."

The mechanism of action of boiling water is to collapse the structure of the plant which ultimately leads to its death down to the root.

In executing this method, start by boiling water in a kettle and transporting it to the gravel area infested with weeds. Whilst handling the hot water, ensure you are wearing your gloves to prevent accidental burns.

Pour the boiling water directly over the weed from a low height to prevent splashing and so as much of the water targets the weeds. Once the weeds have wilted and appear dead, use a screwdriver to loosen the weed's roots and then gently but firmly pull it out.

If gardeners find that this method is not working, Bryan has suggested a chemical weed killer - Roundup. Roundup, a glyphosate-based herbicide, is widely used due to it being "effective", according to Bryan.

However, he always advises people to be cautious if they decide to use it as exposure to it increases the risk of a cancer called non-Hodgkin lymphoma by 41 percent, according to a study from researchers in the UW Department of Environmental and Occupational Health Sciences (DEOHS).
