What does Overwatered arborvitae look like?

Answered by Edward Huber

When Arborvitae trees are overwatered, it can lead to some noticeable symptoms. One of the most common signs is a discoloration of the leaves. You may observe that the foliage turns yellow or brown, particularly on the younger, exterior part of the plant. This discoloration is a result of the roots being saturated with water for an extended period.

Another symptom of overwatering in Arborvitae trees is leaf dieback. This means that certain parts of the tree, such as the tips of the foliage, may start to dry up and eventually die off. This can be seen as a browning or wilting of the affected areas. The excess water prevents the roots from absorbing necessary nutrients, causing the leaves to wither and die.

In addition to discoloration and leaf dieback, overwatered Arborvitae trees may also exhibit signs of root rot. This is a fungal infection that occurs when the roots are constantly submerged in water. Root rot can cause the roots to become mushy, discolored, and have a foul odor. It weakens the tree’s ability to take up water and nutrients, leading to further stress and decline.

Overwatering can also result in stunted growth and overall poor health of the Arborvitae tree. The excess water prevents the roots from receiving enough oxygen, which is essential for their proper function. This lack of oxygen can hinder the tree’s growth and make it more susceptible to other diseases and pests.

To summarize, overwatered Arborvitae trees display symptoms such as discoloration of leaves, leaf dieback, root rot, stunted growth, and overall poor health. It is important to be mindful of the watering needs of these trees and avoid overwatering to ensure their optimal growth and vitality.
