I've got a rock "lawn" and I would like to quit using herbicide for killing
weeds, and try scorching them instead.
There are a lot of weed / roofing torches on ebay and I was wondering if
there is anything to choose for or against in buying one. The one I'm
leaning toward getting says: "3000+ Fahrenheit" - that's enough, right?
I wish, I would have had my bride do that. :-))
We use a weed barrier fabric beneath rock in the desert and still have
superficial weeds pop up in the rocks. A torch has been good when I
needed or used one. They are not routine for me, as I don't own one.

I like the company Leevalley. I went with their advice to water the
target plants. I quick hit of heat with no smoke and moss was dead on
my brick patio in a few days. Boiled I guess ? I purchased to deice
our walk .
Have someone standby with a hose just in case as dry tinder seems to be
about these days.

Maybe they don't want to keep chancing that the herbicide will also affect
Maybe they just don't like storing and handling the extra chemicals.
Maybe it's a large area, and they just don't want to keep contaminating the
ground water, below.
How many rocks can you name, that are flammable?
In the 60's people took acid to make the world weird. Now the world is
Guessing that's about the temperature the bonfire 2 years ago burned at its
height of heat. Cutoff lumber from the builder, juniper ashe, a little live
oak. All dried for about 2 months first. Pile was over 10 feet high, 30
foot around, teepee fashion. Fire laughed at the garden hose at its height.
Absolutely nothing grew there for a full year. Put a raised bed garden over
There was nothing within 50 feet that was a potential for burning, no wind,
overcast, drizzly off and on that day. Watered down the area around the
fuel dump anyway, prior to lighting off. Aluminum cans, and glass bottles
were melted flat. Some steel in some nails melted. Used magnetic pickup
tool to get all the steel remaining afterwards.
You don't have enough propane to do that. Plus, the roots are hiding under
rocks instead of flat ground.
Something that will work for a a year or two is used motor oil. But, weeds
will come back with vengeance. It won't kill them entirely. But, its no
worse than the chemicals and consequential runoff from herbicides that you
have to pay additional money for.
Google "Barton Springs" and "herbicide"
Sounds a bit like my annual event. Here's the before-and-after from
the 2005 one (the most impressive to date:
I used a big magnet in a sock to pick up a 20 litre bucket full of
nails from the site a few weeks later, and I'm still getting a handful
from time to time (I have a post there so that I know not to drive
This years was a little less impressive, but only a little:
