Care of Newly-Planted Trees
Newly-planted trees need active and frequent care during the entire establishment period. In USDA hardiness zones 4 and 5, the establishment period lasts about 12 months per inch of trunk diameter. For a two-inch caliper tree, this translates into a 24-month establishment period. Good cultural practices during this period help reduce transplant stress and create a favorable environment for tree growth.
Consistent and proper care during the establishment period is the most important thing you can do to succeed with your new tree.
