Steps to follow while using a blowtorch to burn weeds
Weeds growing in your grassy yard is not a wonder at all. However, they can take over your garden if not taken care of properly. So, what do you do about it?

- Remove all combustible materials and debris.
- Water the area surrounding the weeds to prevent heat conduction.
- Adjust the flame, keep it burning and point it to the weeds.
- Torch the roots or leaves as this will evaporate the water in the weeds and cause them to die.
- Once you cover all the weeds, switch off the torch and sweep the remnants.
Avoid torching weeds on dry combustible materials during summer or drought periods. Hence, the best time is in spring, early summer, or when the weeds are young.
When young and tender, weeds only need a little heat compared to when they’re mature. And torch them in the morning before the sun will give you get the best results. Torch weeds every three weeks or as fast as they grow until frost.
How long does it take to burn weeds with a torch?
Using a larger propane tank will result in a longer burning time. Also, the tip of the torch determines the burning period. Thus, to burn weeds faster, use a torch with a smaller tip as it burns fuel fast and will extinguish weeds the same way.
Most torches will have guidelines for their burning time, and you can select what works for you depending on the weeds you’re dealing with.
If you’re dealing with broadleaf weeds, flaming will kill them. However, most grasses grow below the ground with a protective sheath. Hence, you face flame-weeding disadvantages like regrowth or singeing other plants. Use a flame weeder weeks apart to suppress its growth adequately.
What permanently kills weeds?
If you seek to kill weeds permanently, there are several methods to use and get the ultimate results. Uprooting weeds only get rid of them for some time, but the method doesn’t eliminate roots and prevent regrowth. So, you should use a technique that attacks and destroys the roots for good.

Homeowners prefer to use the other two vinegar options, not because white vinegar isn’t effective, but because it’s strong enough to damage the soil. However, you can mix it with dishwashing soap to help it penetrate the ground without damaging the soil or nearby plants.

Dishwashing liquid soap alone isn’t effective in removing weeds permanently, but you can make it happen with dishwashing liquid using vinegar or table salt with it. It kills weeds from the internal roots to the seeds. Some mix liquid dish soap with water, then apply it directly to weeds.
Baking soda is a cheap, readily available kitchen supply with various uses, including killing weeds. It’s effective in killing weeds because it contains sodium, which is toxic to plants. Mix baking soda with water, then apply it directly to weeds, and they’ll die. Further, baking soda prevents weed regrowth and fungal growth.
