2022年12月30日 · Flame weeding works best on annual weeds that are 1 to 2 inches (2.5-5 cm.) high. Use flame weeders to kill weeds that grow around garden barriers and fences. They excel at killing weeds in sidewalk cracks, and you can even use them to kill stubborn, broadleaf weeds in lawns because mature lawn grass blades are protected by a sheath.

Flaming will kill annual weeds completely, but does not kill the roots of perennial weeds. Often, gardeners will see new shoots a week or so after flaming and additional treatments can deplete the roots, killing the weeds. For the most effective weed control, use a weed torch in spring and early summer when weeds begin to emerge.

2024年7月12日 · Weed burning is a great chemical-free method for quick weed control. However, it is not always effective for large or perennial weeds. The torch is meant to hover over them for a split second to sear their leaves and heat-kill the leaf cells, not burn them to a blackened crisp.

Overall, flame weeding is healthier than using chemicals. Burning weeds even kills the roots, so the plant can’t return. As long as you’re very careful, burning weeds is usually the better choice!
