Protecting Our Urban Forest: Combatting Tree Decline and Death Caused by Excessive Water in Wisconsin

Homeowners in Wisconsin need to be concerned about the health of their trees following recent flooding. Arborists advise that paying attention to signs of distress and taking preventive measures can help avoid tree decline or death. Too much water is detrimental to most trees in the state, with standing water for more than seven days blocking oxygen from reaching tree roots underground, leading to root rot. Additionally, excess water can wash away soil from roots, making trees more vulnerable to being uprooted by wind.

Adam Passo, district manager at the Milwaukee Davey Tree Office, emphasized the negative impact of excessive water on trees in Wisconsin. He explained that if the root system remains saturated for over seven days, many roots might die. In areas with poor drainage, premature color changes in tree leaves indicate damage. Other signs of distress include wilted leaves, discolored foliage, and pest infestations. Passo noted that the actual stress on trees may not manifest until the following year and that a drier summer could aid in tree recovery.

It is essential for homeowners to monitor their trees’ health and take appropriate action to mitigate damage caused by flooding. By being aware of the signs of distress and implementing preventive measures such as pruning or fertilizing trees when necessary, individuals can support tree health and prevent potential decline or death.

In conclusion, excessive water is detrimental to most trees found in Wisconsin landscapes due to its ability to block oxygen from reaching root systems and wash away soil from roots. Homeowners should be vigilant about monitoring their trees’ health after recent flooding and take appropriate actions to mitigate any damage caused by it.
