Is flame weeding sustainable?
Flame weeding provides a sustainable and affordable strategy to manage weeds in organic corn. In conventional corn-soy rotations, weed control is accomplished through the use of herbicides and usually the crops are genetically modified to tolerate those herbicides.
How do you do flame weeding?
Weeds only need a 1/10 second exposure to the flame, so pass the flame slowly over the weed. If you are weeding rows in a vegetable garden or along a fence line or drainage ditch, walk slowly, about 1 or 2 miles per hour (2 km. per hour) along the area you want to flame.
Does flame weeding work on grass?
Broadleaf weeds are more readily killed by flaming than are grasses. Many grasses have their growing point below ground, or they may have a protective sheath around it, so they can usually re-grow after flaming. Several passes with a flame weeder, a few days or weeks apart, may be needed to adequately suppress grasses.
Do flame weeders really work?
When flame weeding, the most effective method is to catch weeds early, from 1-4 inches. At this small stage, flaming is nearly 100% effective at killing weeds, whereas weeds over 4 inches are more difficult to kill without multiple flamings.
Is burning weeds better than spraying?
Roundup is relatively easier to apply since all you need to do is spray it on the nasty weeds. It will take over at that moment and compromise the plant’s biological processes, killing them. Conversely, weed burning devices take a little longer to work.
Will burning weeds keep them from growing back?
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.
Can I burn weeds in my garden?
Burn Them. Yes, really—killing weeds with fire is safe and controllable with a weed burner. Rather than wasting precious time pulling weeds, walk about in early spring and summer burning tender seedlings. Burning weeds requires the least effort when the plants are small, so start early.
Is burning weeds good for the soil?
Flame weeding (also referred to as flaming) has been an apt option for organically ridding row crops and fields of uninvited weeds while also replenishing the soil with nutrients from the resulting carbon.
Is it good to burn weeds in the garden?

Can you burn weeds in a fire pit?
You might be tempted to dispose of yard weeds in your backyard fire pit. Don’t! Burning the irritant oil in the plants, called urushiol, releases fumes into the air. This can cause lung irritation and severe allergic respiratory problems.
