Gardeners looking for an effective, eco-friendly way to tackle patio weeds this spring are being urged to try boiling water instead of vinegar or salt. According to Kaw Valley Greenhouses, a gardening centre, pouring boiling water directly onto weeds is one of the simplest and most cost-free methods available.
Unlike vinegar or salt, which often fail to penetrate deep enough to destroy the root system, boiling water can reach the base of the weed and completely obliterate the roots. This reduces the likelihood of regrowth and helps prevent weeds from widening gaps in paving, which can lead to cracks and uneven surfaces.
The method is also safe for surrounding plants and wildlife, as the water cools quickly after contact. To apply, simply boil a kettle of water, carry it carefully to the patio, and pour it slowly onto the centre of the weed from arm's length to avoid splashback. For best results, choose a sunny day, as rain can cause the water to cool too rapidly.
Within a day, the weed should begin to wilt and turn brown. Once dead, the foliage can be removed, leaving the patio weed-free. The technique is particularly recommended in spring, when chemical weed killers and even organic alternatives like vinegar can harm nearby flowers or lawns that are starting to regenerate.
