Trees shall be planted and established with a straight trunk, perpendicular <br /> to the ground. This can be accomplished through proper planting and staking. <br /> 11.1 Stakes shall be one or two hardwood stakes driven firmly into the ground <br /> outside of the hole to prevent root damage. <br /> 11.2 Attach the tree to the stakes at knee height using nonbinding tree ties or tree <br /> ties that are at least 1" wide to prevent damage to the tree trunk. <br /> 11.3 Attach the ties to the tree in a manner that allows the tree to move but still be <br /> held firmly in place.
