How to Kill Weeds With Hot Air
- 1). Fill the handheld steamer with water.
- 2). Plug the hand held steamer into an outdoor power outlet. An extension cord is necessary to maximize the maneuverability of the steamer as you move through the garden.
- 3). Turn on the steamer. Wait at least one minute for the water to heat up.
- 4). Point the steamer at the weeds at close range and blast them with hot steam.
- 5). Watch for the waxy coating on the weeds to turn a dull matte. Removal of this coating makes it impossible for the plant to retain water, ensuring that the weed will die.
