Most gardeners understand the need to water consistently and deeply during the warmer months, but it’s just as critical to water trees and shrubs as you head into the colder months.
Good snow cover can help insulate roots and moderate soil temperature, but many areas can’t rely on consistent heavy snow all winter. To create a layer of insulation, apply a 3- to 4-inch layer of organic mulch over the root zone of your trees and shrubs.
Start wrapping your tree from the bottom up, overlapping the wrap by a third until you reach the first branch. Secure the wrap with a knot or a piece of twine to keep it from slipping down, and make sure to remove it in early spring.
