8.2.2 Inspect roots for a girdling or circling condition. If girdling or circling roots are present, gently straighten or cut back any offending roots unless root manipulation will be too extensive, in which case the tree shall not be planted. 8.2.3 Trees shall have been grown in the container for a maximum of one year. 8.3 Bare root trees: 8.3.1 Roots shall not be allowed to dry out at any time. 8.3.2 All dead, damaged, broken or frayed roots shall be pruned off prior to planting. 9. Planting Procedures. 9.1 Set the tree on undisturbed solid ground in the center of the hole so that the upper surface of the root ball or root flare is slightly above the surrounding soil. 9.2 Set tree plumb, upright, and faced for best appearance. Prune to remove any broken branches. 9.3 Gently backfill the hole '/z full with original soil and flood hole with water to remove any air pockets. 9.4 Continue to backfill the hole, and when completed, thoroughly saturate the planting area with water to remove any remaining air pockets. 9.5 Apply 2-4 inches of mulch around the tree. Maintain a mulch free area within 2 inches of the trunk. 10. Watering Basin. Create a continuous 3 inch high raised berm of soil around the hole to direct water to roots, remove the berm after one year. 11. Staking. Trees shall be planted and established with a straight trunk, perpendicular to the ground. This can be accomplished through proper planting and staking. 11.1 Staking shall be two to three stakes driven firmly into the ground outside of the hole to prevent root damage. 11.2 Attach the tree to the stakes at 1/2 to 2/3 height using nonbinding tree ties or tree ties that are at least 1 inch wide to prevent damage to the tree trunk. 11.3 Attach the ties to the tree in a manner that allows the tree to move but still be held firmly in place. This will help develop trunk taper and add strength to the tree. Administrative Order - Page 9 of 14
