This particular job is a favourite one with many in the industry as you are involved in replacing trees that you may have removed and have a hand in leaving a legacy for generations to come. Knowledge is required of many aspects of this including selecting species and matching them to sites especially in streets where conditions are often hostile. One should also consider carefully points such as what is the best size and whether it should be a bare rooted tree or a containerised tree. Access with a vehicle will be a major deciding factor, because the larger the tree the greater challenge delivering and moving the tree to the pit will be. Advice here is to speak to the supplier or at least an experienced nurseryman with knowledge of this subject before making a selection.
