This winter has been exceptionally dry across the Four Corners, and in many places there isn’t even snow on the ground — which means our trees may actually be more stressed than they look. Even though trees are dormant, their roots can still dry out during long cold, dry spells, and that can lead to dieback later in the spring and summer.
With warmer temperatures expected this weekend — highs in the 50s here in Cortez — it’s a good window to give trees a deep drink. The general rule is to water one to two times a month when there’s little snow cover and the ground isn’t frozen. Water during the warmest part of the day, and go slow and deep so moisture reaches the roots.
Young trees and evergreens need extra attention, since they lose more water to dry winter air. A layer of mulch around the base can also help hold in moisture and protect the soil.
It may feel strange to water in January, but in a dry winter like this, it can make a big difference come spring.
