Road salt also leads to brown shoots. Therefore always plant a thuja hedge sufficiently far away from roads and paths that are kept free of ice with road salt in winter.

Root rot occurs when the tree of life is in a wet location. Waterlogged Thuja does not tolerate emerald at all. Ensure good drainage of the soil.
