How to Plant a Tree: Tree and Shrub Selection and Planting

Rocky Mountain Gardening Elective

 

Trees and shrubs are one of the greatest investments we can make in our property and if cared for properly, can increase the value of our homes ten-fold or more. They are also a big investment and one that we often relegate the important decisions about to others.

How do you know what to plant where, when the best time to plant is for evergreens or deciduous trees and shrubs or the difference in planting strategies for a balled and burlapped specimen or a containerized plant?

Do you know what to look for when you go to the nursery to select a tree or how to dig a proper hole and amend it correctly to insure the best root spread in the appropriate amount of time? Should it be pruned after planting and how? And do you know how to properly care for your investment to avoid transplant shock or winter dessication injury?

We will cover all these concepts and more to make you more confident when choosing or planting trees and shrubs in your landscape or when supervising contractors who will do the job for you.
