In the fall trees drop their leaves and go into an apparent dormant state, so we don’t think much about watering them during the winter. What we don’t realize is that the roots continue to grow throughout the winter – and do need water.
All trees benefit from winter watering but in Draper, with our dry air and soils, it’s especially important for evergreens to receive water year-round. As a general rule, trees should be watered 1-2 times per month during winter when the ground is not frozen. Young trees should be watered more often. The roots best able to use water are at the “drip line” – the area where water drips off the tree in a rain storm.
Trees should be watered to a depth of about twelve inches along the drip line and under the tree canopy. This will make sure all the roots get the water they need. Trees that don’t get adequate water during the winter months may not die, but it may stunt their growth and increase their risk of secondary diseases and insect infestations. Make sure your trees get adequate water year-round.
