Thuja fungal diseases and their treatment are much more serious. Flushing alone is not enough. The fungus can also cause blackening, but the formation of spores is also characteristic of it. With a small lesion area, the thuja is treated with a fungicide twice, maintaining an interval of 1-2 weeks. The damaged parts of the plant are removed, and further preventive measures are taken (spraying with Bordeaux mixture or biofungicides).

If the site is located in a place open to the sun, then it is better to install a sun shield on the south side. Subject to these simple rules, thuja will be healthy, green and will serve as a real decoration of the landscape.
