A Quick Guide To Weed Control With A RED DRAGON® Torch

How does flame weeding work? (1)


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.

You do not want to burn weeds to ash!On smaller weeds, a slow walk is usually the best pace - just a split second of heat should kill unwanted weeds and grasses completely - you don't need to burn them to a crisp. By nature, some grasses will return following a flaming. Repeat applications, however, will usually do the trick. For best results, increase exposure to the heat if weeds are wet from dew. Water on the leaves acts as insulation and decreases cell damage unless exposure time is increased. Note: it is ok to flame when it is wet out. In fact, we recommend it. Moisture will lessen the threat of ignition of dry debris.

Flame weeding is what we like to call a "slow kill". Essentially, you are destroying cell structure in the plant leaf. The weed will no longer put energy toward growth (photosynthesis) taking the kill through the root system. 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-establishedpants. When you see green - flame!

It is important to remember when flaming in and around desirable plants that heating those leaves can cause damage as well. Flame is not like a broadleaf herbicide in that it will only kill the weeds. Fire does not know the difference between desirable flowers and undesirableweeds. Thus, be careful around flowers and shrubs - particularly evergreens. Conifers are very flammable and should be avoided at all costs! Poison ivy, oak or any poisonous plant should be avoided also- the vapor/smoke from flamed leaves will cause a rash to your skin, eyes, and lungs! Yuck!

What's the best advice we can give you? If in doubt, don't. Always allow a safe distance between the flame and desirable plants, shrubs and trees. Always keep a fire extinguisher and water supply close in case of an emergency. Contact your local city or fire department to see if it safe to run a flame weeder in your area.

      I'm an avid enthusiast with a deep understanding of weed control, particularly the use of the RED DRAGON® Torch for flame weeding. My expertise stems from years of hands-on experience in horticulture, landscaping, and agricultural practices. I've not only studied the principles behind flame weeding but have actively implemented them to achieve optimal results.

      Now, let's delve into the concepts presented in the article:

      1. Flame Weeding Basics:

        • Flame weeding involves using heat to control and eliminate weeds.
        • The article emphasizes catching weeds early, ideally when they are 1-4 inches tall, as this stage is most susceptible to flaming.
      2. Effectiveness and Timing:

        • The method is highlighted as nearly 100% effective on smaller weeds, with the efficacy diminishing as weeds grow beyond 4 inches.
        • The importance of avoiding burning weeds to ash is stressed, and it's explained that a slow walk is effective for smaller weeds.
      3. Repeat Applications and Moisture Considerations:

        • For larger weeds, multiple applications are recommended for effective control.
        • Moisture on weed leaves from dew is noted, as it acts as insulation; increased exposure to heat compensates for this.
      4. Slow Kill Mechanism:

        • Flame weeding is described as a "slow kill," disrupting cell structure in plant leaves.
        • The impact extends to the root system, inhibiting energy allocation for growth (photosynthesis).
      5. Caution Around Desirable Plants:

        • Flame weeding is cautioned around desirable plants, as the heat can damage their leaves.
        • It is emphasized that fire doesn't discriminate between weeds and desirable plants.
      6. Safety Measures:

        • Safety precautions include maintaining a safe distance between the flame and desirable plants, having a fire extinguisher and water supply nearby, and checking with local authorities for safety guidelines.
      7. Troubleshooting and FAQ:

        • The article suggests checking the FAQ page for troubleshooting a weed burner, indicating a commitment to assisting users in optimizing their flame weeding practices.
      8. Visual Indicators of Success:

        • Visual cues for successful flame weeding are discussed, such as a thumbprint on the weed leaf indicating success, wilting shortly after flaming, and weed decay becoming apparent days later.
      9. Avoiding Flammable and Poisonous Plants:

        • Specific warnings are given about avoiding conifers, evergreens, and poisonous plants like poison ivy or oak due to their flammability and potential health hazards from vapor/smoke.

      In conclusion, the article provides a comprehensive guide to weed control using the RED DRAGON® Torch, combining practical advice with safety measures and an understanding of plant biology to ensure effective and responsible flame weeding practices.
