Why do your cedars all of a sudden have brown throughout them?

Brown foliage in cedars can indicate several issues, such as drought stress, pest infestations, or diseases like cedar Apple rust. Environmental factors, like sudden temperature changes or poor soil drainage, can also contribute to this issue. It’s important to assess the overall health of the tree, check for any signs of pests or fungal infections, and ensure proper watering and care to address the problem effectively.
