Exposure to harsh conditions is one of the more common reasons arborvitae can turn brown, and heat isn’t the only culprit. Intense winds can also be a cause for brown arborvitae. If your tree is suffering from browning during the winter, harsh winds and freezing temperatures may be to blame. As the temperature drops, the ground may freeze and cause the roots to freeze as well. This makes it difficult for the roots to take in water and even more difficult for the lower part of the tree to share the water it has with the higher parts of the tree. This causes desiccation to occur. The top of the tree is still producing energy, despite not having access to water, and the sunlight hitting it can cause parts of the tree to die. When the weather is causing damage to your tree, it’s up to you to protect it.
