Weeds that keep sprouting can drive hobby gardeners to despair. But how can greenery be permanently and effectively removed from the joints of terrace and pavement slabs? They can be kept clean very easily with hot air weed killers. You can find out how they are used correctly and how they work in this article.
What are hot air weed killers and how do they work?
Weed hot air killers are electrical devices that use hot air to combat weeds. They are environmentally friendly, safer than gas appliances, protect the joints and do not require joint sand. Multiple applications may be necessary and they require power.
What are hot air weed killers?
With these electrically operated devices, the weeds are destroyed using hot air and not a flame, as is the case with gas-powered flame devices. The heat causes the proteins inside the plant to coagulate and the cell walls to burst. As a result, the weed dies. The hot air flow also reaches the roots and damages them, so that new growth is greatly reduced.
How environmentally friendly is this technology?
Hot air weed killers require electricity, but apart from that they are very environmentally friendly. The air jet, which is up to 650 degrees hot, is directed at the weeds for just a few seconds, which then dries up and can easily be swept away.
Unlike with gas appliances, the plant initially looks relatively intact after heating. Don't let this fool you: after a few hours or days it will wither.
What advantages do the devices have?
- Because there is no open flame, these devices are considered safer than those that run on gas.
- Thermal destruction protects the joints.
- In contrast to removing weeds with the joint scraper, no joint sand needs to be spread after weeding has been carried out with the hot air device.
- Since the hot air flow can be used in a targeted manner, ornamental plants in the surrounding area are protected.
Are there any disadvantages?
When using the hot air weed killer, you are dependent on electricity. The extension cable required for this limits the working radius. Therefore, these devices are rather unsuitable for very large properties.
Several applications may be necessary until the weeds finally die down.
Tip
Hot air weed killers often have practical additional functions. With some devices you can light the grill, remove paint and varnish and even de-ice objects.
