While some trees in Wisconsin are more tolerant of drought than others, we do not have trees that are fully adapted to drought. Therefore, it is absolutely essential that trees receive sufficient water throughout a drought period. Here are some awesome tips from Tree Health Management.
YOUNG TREES (TREES TRANSPLANTED/PLANTED IN THE LAST 5 YEARS)
The best way to water your young trees and shrubs is the slow-soak method. A deep watering over an extended period (like a slow-drip from your hose for several hours or a root feeder) is the best way. This will allow the moisture to go deep to the bottom of the roots. The majority of the water-absorbing roots are in the top 18″ of ground. During the months of May thru September, trees should be watered every other day there is no rain. If we receive precipitation of 1″ or greater, refrain from watering that day. If the ground is saturated from previous rains, refrain from watering. Trees should receive approximately 2 gallons of water per inch of caliper. For younger trees, around 5-10 gallons of water should be sufficient.

ESTABLISHED AND MATURE TREES
When it comes to mature trees, their well-established roots mean less fuss when it comes to watering. A watering schedule of 10-14 days will be adequate. This means that if there is no recorded inch of precipitation during the week according to the barometer or local weather station, you should water your tree with 2 gallons of water per inch of caliper.
Given the current drought conditions, it’s crucial to be mindful and increase watering to support the tree’s health. Monitor the soil moisture and adjust accordingly.
It is crucial to alleviate drought stress in trees, as trees experiencing drought stress are more susceptible to increased insect and disease pressure. This is particularly important for our patients that are currently in the ER. If your tree is undergoing treatment for a disease or insect issue, it becomes extremely important to alleviate drought stress.
