Chestnut Trees together

Chestnut Tree Treatment was founded in 2015 by dutch entrepreneurs who have a heart for environmental sustainability and love for parks and trees.

The company wishes to enlarge the public awareness of possibillities to cure weak and affected chestnut trees. Cutting down the tree is not always the only solution!


With the special developed heating blankets some chestnut trees affected by Pseudomonas syringae can now be saved with a treatment that will only take a few days.The sick tree will be wrapped in our special blankets that can warm up the tree and can kill most of the pseudomonas syringae bacteria. After the treatment the chestnut tree will be able to recover and clean up the remaining bacteria.


After the succesful tests with Anecdotal evidence as a result Chestnut Tree Treatment is now ready to take it a step further, a full-fledged Scientific field study with which the law of the large numbers can take effect.

We can not do this alone, we need the local governments and public's help to start more field studies to treat more sick chestnut trees. If you have seen a sick chestnut tree, or have questions about our Treatment program, please feel free to contact us on so we inform you or can add the tree to the map and list of chestnut trees in need of treatment. Report all sick chestnut trees! Let's do this together!
