Opinions differ greatly on this question - some people want to give nature free rein and allow all "wild herbs" - as weeds are also known - to grow unchecked. For others, the aesthetic aspect takes centre stage and a weed-free garden is the top priority. Basically, it can be said that the growth of plants of all kinds is not desirable in every place around the house, yard and garden - in some cases more, in others less. Especially as damage to buildings, for example, caused by heavy weed growth can also be a solid reason to put a stop to nature in some places. The question now arises as to how weed control can be organised in the most environmentally friendly way possible without endangering the health of humans and animals. Here you will find information on biological weed control with hot water - including a comparison with other methods.
The water-impermeable wax layer (cuticle) that surrounds each leaf is damaged
Hot water now penetrates to the individual cells of the weed and these burst due to the high temperatures. The protein in the plant's cells freezes at temperatures above 42 °C. This reaction can no longer be reversed, like the protein in a boiled egg.
Thanks to gravity, the water seeps into the upper soil layers and destroys the fine roots of the weeds there.
Thermal weed control using only hot water is a modern and proven method of getting rid of weeds in the long term. The process affects the entire plant, leaves, stalk and roots. The long-term success is mainly due to the fact that these effects cannot be reversed.
- In-depth effect : The method does not exclusively affect the foliage, but also on the roots and seeds of the plant. The fine secondary roots are destroyed, which significantly reduces the surface area for the absorption of nutrients and water is significantly reduced - the plant becomes weaker and weaker.
- The method is very effective. This is due to the properties of water. The hot water quickly covers the entire surface of the leaves, not just part of them, as is the case with vapour.
- Due to the high level of efficiency, the majority of the plant is destroyed with just one application. The frequency ofnecessary applicationsdecreases significantly in subsequent years.
No sunlight
The leaves of the weed can no longer absorb light and therefore cannot photosynthesise
No water
No nutrients
The weeds can no longer absorb nutrients and are weakened down to the roots in the long term
Problem-free use on terraces, paths, lawns, flower beds and high-quality ceramics
Targeted and pinpoint work, e.g. for individual weeds in the lawn
Sustainable effect - minimises the weed burden in the long term
The use of hot water offers an economical solution and an ideal alternative to weedkillers. The highly efficient technology is also gentle on the environment. The hot water (95° C) first destroys the cell structure in the leaves of the plant above ground. Photosynthesis can no longer take place. The plant can no longer absorb nutrients and dries out. The hot water penetrates to the roots, causing the plant itself to die after repeated applications. Removing weeds with hot water is up to 20 times more effective than with conventional methods such as gas burners or hot air blowers and other household remedies. Our Unkrautfuchs works with constantly regulated hot water (temperature above 90°).
Results of the University of Copenhagen
A study carried out at the University of Copenhagen shows that treatment with hot water results in the lowest weed coverage, even with the lowest treatment frequency.
It also shows that, in comparison, treatment only needs to be carried out 4 times a year.
Studies by the University of Ghent
The experiment carried out by Dr. Ir B. De Cauwe at the University of Ghent showed that hot water has the highest thermal conductivity and heat capacity, which means that it provides the highest kill ratio compared to others tested.
In the figure below you can see the tests carried out 7 days and 21 days after the application of three different methods at the University of Ghent.
