Jack Frost descends upon us all in Wisconsin, but the depths to which he brings the mercury differ depending on your latitude, elevation, and proximity to water or urban areas. These differences are observed in a location’s cold hardiness zone, which represents the average minimum temperature a location is expected to experience.
Cold hardiness zones are well-known decision-making factors for anybody with a smidge of green on their thumb. But did you know that there are multiple hardiness zone maps out there, and that where you stand right now might be in zone 6 on one map, but zone 5 on another? Enter the labyrinth, dear reader.
To keep everyone safe and healthy during this pandemic, the Arbor Day Foundation is suspending the requirement to hold a public Arbor Day celebration in 2020. Communities will be able to maintain their Tree City/Campus/Line designations without meeting this standard.
Are you going stir-crazy stuck inside your house or apartment? Take a visit to the forest outside your door! Step outside to enjoy the sights, sounds and smells of the trees and nature around you. It’s good for your mind, body and soul. Research shows exposure to nature reduces depression, anxiety and stress! Plus, we all know physical activity keeps your body healthy and boosts your mood. 
Our thoughts are with the families who are grappling with school closures, while balancing work and facilitating their children’s school days. There have been many online sources for continued education for all levels of schooling and we encourage you to check them out in addition to those provided by your local schools.
