tree moving machine, planting, landscaping, tree spade
Using a tree moving machine, often called a tree spade, can provide an economical way of obtaining larger trees in the landscape. The tree spade moves a tree with a soil plug attached. Tree spade trees are moved either from nurseries, where they have been especially prepared for transplanting, or from sites where they are already growing in a landscape. Nursery-grown trees generally provide better transplanting success, but, with proper selection and care, trees can be moved from one landscape to another. Moving large trees with a tree spade requires a good knowledge of the different species’ reactions to transplanting. An experienced tree spade operator can make the difference between success and failure.
