Reducing Winter Related Injury in Landscape Trees (pdf)

Montana can have harsh winter conditions that can sometimes challenge even our hardiest trees and shrubs, especially if steps aren’t taken to set them up for the best success. Last winter was especially tough on many of our landscape trees and shrubs, and we saw significant amounts of winter injury across the state. Follow these tips to set your trees and shrubs up for a more successful winter this year by allowing them to harden off and protecting them from common winter-related injuries.

Minimizing Deer Damage in Residential Landscape Settings

Deer are generalists that can persist across a wide range of habitat conditions. They favor early vegetation stages that keep brush and sapling browse within reach. Dense cover is used for winter shelter and protection. Because deer are so adaptable and residential areas sometimes provide suitable habitat conditions, deer can pose challenges to homeowners.

Xeriscaping and Other Thoughtful Landscaping Practices to Conserve Water

Drought conditions and limited water supplies in much of the semi-arid West can reduce water availability for irrigating home landscapes. This makes water conservation an important component of gardening in Montana and beyond. Xeriscaping, a term originally developed by Denver Water (derived from the Greek word “xeros,” which means ‘dry’), is a method of landscaping that incorporates water conservation strategies to minimize water waste and reduce the need for supplemental irrigation.
