The tree should have a single central leader. Multiple stems on a young tree will result in splitting as the competing leaders mature. Inspect the tree for damage to the trunk. Discolored, sunken or swollen areas indicate trouble. Note whether pruning cuts have callused over.
Fresh cuts indicate a recently shaped tree to appeal to customers.
Always check under tree wrap applied in the sales area. Avoid trees that have a great number of branches close together on the trunk. Such branches will be weak and create pruning problems later. 3-inch caliper tree should be 14 to 18 feet tall with a 32 inch minimum root ball. Check that the trunk is centered in the root ball.
