By
destroying cell structure in the plant leaf, the weed will no
longer put energy toward growth, so even on big weeds, you will
see a stunting effect or even a kill, depending on how established
the root system is and how long the plant was exposed to heat.
On smaller weeds a slow walk is usually the best pace - just a
split second of heat should kill unwanted weeds and grasses -
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.
It is important to remember when flaming in and around desireable
plants that heating those leaves can cause damage as well, so
be careful around flowers and shrubs - particularly evergreens.
Conifers are very flammable and should be avoided.
Poison ivy, oak or any poisonous plant should be avoided also-
the smoke from flamed leaves will cause a rash to your skin, eyes
and lungs!
What's the best advice we can give you? If
in doubt, don't. Always allow a safe distance between the flame
and desireable plants, shrubs and trees. Always keep a fire extinguisher
and water supply close in case of an emergency. |
