Add words or change punctuation as you need to.Before planting a tree, a gardener needs to choose a good location and dig a deep enough hole. The location should have the right kind of soil, sufficient drainage, and enough light for the type of tree chosen. The hole should be slightly deeper than the root-ball and about twice as wide. The gardener must unwrap the root-ball, for even burlap, which is biodegradable, may be treated with chemicals that will eventually damage the roots. The roots may have grown into a compact ball if the tree has been in a pot for some time, and they should be separated or cut apart in this case. The gardener should set the root-ball into the hole and then begin to fill the hole with loose dirt. After filling the hole completely, he or she should make sure to water the tree thoroughly. New plantings require extra water and extra care for about three years before they are well rooted.
