Does anybody use a weed torch?

[DirtMechanic]

If so, I assume it runs on a propane tank? What details are important to you about how it works?

Be very careful and not to use it during dry weather .. it can cause devastating fires..

You can use vinegar .. more organic.. and you don't have to buy the gas cylinder for the torch.

I do quite often. For garden weeds and grasses and more importantly to light my BBQ wood.

I've got a weed blowtorch, which I use to get weeds that grow between paving stone and the road - there's a relatively long and windy stretch and I don't want to use anything too unpleasant on it as we often have the neighbours cats and dogs nearby.

Thankfully there's nothing flammable near where I use it, other than the weeds themselves - it's great fun . However, I won't use it during Autumn, as there are so many dried up leaves blowing around that I could easy imagine something catching alight.

You want the tourch to be long enough ... So you don't have to bend over

Does anyone know the psi coming out of the gas bottle?

Using a little soldering tank and tip I have not had any luck. I was only trying to do about 8 sq‘ as a test. If it was green it really took much time and gas to kill it. I didn't do much brown, but with much of my brown the real "life" of the weed is underground anyway. Also left kind of a mess in general as nothing was compeletely burned away.

I probably don't have as much area to deal with as some of you all, but the real eye opener to me was understanding what weeds are annual and what weeds are perennial. If annual scrape the top off and many will not come back up. If perennial pull. Do this before they start going to seed and you will see the results over the course of the next year or two.

I can see the residual char as being useful for the garden. We have irrigation lines runs so errant flame is no issue. Its not a huge patch either, but big enough that hand pulling is just not really working for me, though I have pulled after rains and brought wheelbarrow load after load of grass to the compost pile.

@Chuck I found this on the net:

According to the publication NFPA58, a tank with 20 pounds of gas at 70°F has a pressure of 145 psi, at 90°F would have 180 psi, at 105°F would have 235 psi, and at 130°F would have 315 psi.

It certainly explains why my gas grill is so sluggish on cold days...
