Our dry fall weather and impending winter weather means our trees and shrubs need some watering help from us. The following article from Denver Water provides some valuable tips to help us take care of our trees and shrubs to ensure a green spring.
Winter in Denver includes snow and cold, but long dry stretches and warm temperatures are not unusual. especially since this fall has been one of the driest in Colorado history. “The occasional hand-watering of trees and shrubs in the winter is helpful. A few gallons go a long way this time of year,” said Jeff Tejral, water efficiency manager at Denver Water. Watering during dry stretches, when there’s been no significant precipitation for about three weeks, will prevent root damage that affects the health of the entire plant. Apply the water at the “drip line,” the area at the outer edge of the plant’s branches, so that it reaches the roots. A 3-week dry spell means:
• Trees: Need about 10 gallons of water for each inch of the tree trunk’s diameter.
• Shrubs: Need between 5 and 18 gallons of water.
Water only when temperatures are above 40 degrees with no snow on the ground. Frozen soil won’t absorb water. Keep moisture in the ground by putting mulch under the plant’s branches, leaving a few inches of space around the trunk of the tree or base of the plant.
