The weed burner is very easy to operate.
- Slowly move the device over the weeds you wish to remove at a distance of about 3 cm.
- The high temperatures will boil the sap of the plants’ cells: the cell walls will expand, crack open and dry out.
- The plant may look unaffected immediately after the treatment, but it will dry out automatically within a few days. The effect will not be short-lived and the weeds will be removed in the long term.
For effective weed control, it is best to do your flame weeding in spring and early summer, when annual and multi-annual weeds start sprouting. It requires a lot more heat to kill large, mature plants, so you can save time and fuel by destroying the weeds when they are still young and tender.
To make your flame weeding more effective, it is advisable to repeat the treatment after 2 to 3 weeks. Burning annual weeds will kill the plant completely, but it will not stop multi-annual weeds from rising again, as it does not destroy their roots. The roots of multi-annual weeds will start to grow new shoots within a week. Additional treatments will eventually deplete the energy stored in the roots and the weed will die.
