With some new research linking glyphosate with cancer and other research saying it is safe, it becomes very confusing. We all make a personal choice on deciding on what we want to believe, so some of you may be thinking about alternatives. Unlike glyphosate, weed burners are not a chemical spray, so their method of destroying weeds is not systemic.They work by damaging the weed's leaves with a blast of intense heat that could be as high as 1200 degrees celcius. Only the area where the heat gets to is damaged. The roots are left intact. Leaves feed the weed via photosynthesis, so with no leaves the weed starves and dies. However, if it has an established root system (like a dock, oxalis etc) it may have enough food reserves to recover. Persistant burning will eventually kill even the largest weed because it will run out of reserves.
Since weed burners are not systemic, if you do happen to singe the odd leaf of a wanted plant it will probably recover as long as it has a few intact leaves to grow on with.
Wide variety of use, not just weeds. Burning holes in weedmat for instance, but the best, we sold one to the NZ Stunt School for setting people on fire! Don't try this at home.
How effective are weed burners?
One effective method of controlling weeds without sprays
Plan ahead. Burn off the weeds in your garden with your LPG weed burner at least a month before you intend to plant it (see above). Prepare the soil so it is a fine seed bed. If you have one of our Mantis tillers this is ideal as it will produce a lovely fine seed bed, perfect for weed germination. The idea here is to make the garden perfect for growing weeds. Water your garden well to get the weed seeds to germinate. When the weeds get to the two or three leaf stage (see picture below) burn them off with your weed burner. It is important to methodically go over the whole patch of garden as if you are painting it, because there are many small weeds present that are often hard to see and you need to get them all. If you only focus on the weeds you can see you will miss some.
You have now have removed a large number of the weed seeds from your soil. When planting, try not to disturb the soil too much.If you use our Leeaky Hose for irrigation it will keep the soil surface dry and thus reduce further weed germination.
