1. Plant native - plant tree native to the area as they are adapted to the local soil, climate, and wildlife and help with the areas natural development.
2. Preventative pruning - Weak branches, especially on young trees can break due to wind and ice/snow. Pruning the tree during the dormant season of fall or late winter can reduce risk. A recommendation is to work with an arborist, particularly for mature trees.
3. Water before freezing - Watering before the ground freezes reduces risk on winter drought and windy conditions that can dry out the tree. Look at appropriate amounts of water for the age of the tree and avoid over watering.
4. Mulching for insulation and protection - Adding mulch like wood chips, leaves, and organic materials, helps insulate and protect tree roots from temperature changes over the winter. Mulch in the growing season will also help with weed prevention. Keep mulch about 6 inches clear from the trunk to avoid rot. Optionally add compost below the mulch to give the tree a nutrient supply.
5. Tree wraps, guards, barriers - Wraps and guards protect the tree from foraging animals, sunscald (too much sun exposure), and winds. Different wraps or guards may be needed depending on the local animal. Burlap barriers help evergreen trees survive better in winters and allow air circulation. Remove items in early spring to avoid moisture build up and rot.
6. Winter care - During the winter, mark trees like with tall markers if they are near snow plow areas and avoid salt use near the trees. For slippery surfaces, using sand near trees is preferred. Brush off large snow build up to prevent damage to branches.
