If thuja has turned brown after winter, what should be done in this case should be determined after establishing the causes of such trouble. The most likely factors are:

  • fertilizer oversupply;
  • alkaline water;
  • damage by pests or diseases.

To prevent burns in February, it is recommended to cover the plant with gauze or mosquito net. If we didn’t manage to prevent the negative impact of sunlight, then we need to start watering with warm water, and with the onset of steady heat, cut off the darkened twigs.

When the water stagnates, the soil around the tui is loosened and treated with antifungal drugs. If it was found that groundwater is too close to this place, then only transplanting the bush to another place will help. Fertilizing the soil costs only twice a year, using manure for this purpose.

Only weak acid and weak alkaline soil is suitable for growing tui. At detection of elevated rates it is necessary to take measures to reduce them. If necessary, make lime or peat.

Fungal diseases of thuja and their treatment is a much more serious matter. One washing here will not do. The fungus can also cause blackening, but it is also characteristic of the formation of disputes. In a small area, the lesions are treated with fungicide twice, maintaining an interval of 1-2 weeks. Damaged parts of the plant are removed, and further preventive measures are carried out( spraying with Bordeaux mixture or biofungicides).

Dead plants are a source of infection, so you need to take care of their timely removal from the site. Damaged branches are also removed and burned to prevent the spread of the disease to another territory.

If the thuja was wintering covered, but do not rush to remove the covering material from it: this should be done gradually so that the plant can get used to the sun and not get burned. If the site is located in a place open to the sun, then on the south side it is better to install a sun shield. If you follow these simple rules, the thuja will be healthy, green and will serve as a real decoration of the landscape.
