Does Boiling Water Kill Weeds

There has always been a war going on between gardeners and weeds for decades. Each battle involving a different strategy from home remedies to professional applications trying to find a way to eradicate the ever invasive weed.

Over the years we’ve learned a few tricks that help in keeping weeds away apart from pulling, spraying, and digging. There’s another simple way of keeping weeds away, using boiling water.

Boling water will not only kill the weed but also the seeds that are dormant in the soil. The heat destroys the plant and its root tissue and the plant withers and dies within a day or two. However, boiling water works better on weeds on your driveway, garden path, and walkways away from other plants and grass.
