At least if you can't avoid it, you can reduce your costs by using a tool that doesn't need much energy and maintenance, is work effective and takes care of the roots of your young trees.
This proper tool, after several years of research, we will display it to the French forestry fair Forexpo on the 15th, 16th and 17th of June this year, close to Bordeaux.
Feel free to come and see it work !
I would be delighted to welcome you.
