How to get rid of weeds with a blow torch. When it comes to weed control methods, using a blowtorch is definitely an effective option! First, clear the area of any debris before passing the flame over the roots or leaves of your weeds, causing them to die. Once you're done, remember to sweep away any burnt remnants!
Does torching weeds work well?
YES, flame weeding will kill the roots too! Even on big weeds (over 6"), you will see a stunting effect and even a kill within a few days, depending on how established the root system is and how long the plant was exposed to heat. Again, multiple application may be necessary for well-established pants.
How do you use a blowtorch for weeds?
Light the torch and walk slowly in the area to be weeded, passing the flame along the weeds. Apply the torch to the root or leaves of the weeds, which will cause the moisture within the weed to instantly evaporate, causing the weed to die. Sweep any extinguished remnants from the area.
Can I torch the weeds in my garden?
For the most effective weed control, use a weed torch in spring and early summer when weeds begin to emerge. When plants are torched early, gardeners can save time and fuel as smaller weeds do not require as much heat as mature plants. Also, they can kill off annual weed seeds that are found at the top of the soil.
