01 the plant. . " a container plant appears to be "root-bound", score the roots approximately 1/8 Inch deep vertically in no less that lour locations around the ball and across the bottom. Some larger roots can be "teased" out to avoid cutting them, In alllplantings, the root ball can be broken up and spread out belore planting to encourage better root growth closer to the surface and in- crease survival chances. " Backlill pit with a mix 01 1/3 coarse peat, 1/3 topsoil, and 1/3 site soil, " Do not compact the backfill by tamping, " Build a watering basin with the extra backlill mix and water to cause settting and wetting 01 backfill, Add backfill as needed to prevent ex- posing the plant's root ball. Again, do not tamp or cut in added backfill, . ~ it may be necessary to cut holes in the watering basin belore leaving the site ilthere is a tendency lor water to puddle due to heavy soils, a rainy or heavy snow period, or il exces- sive outside water cannot be avoided, The soil that is removed should be lell on site so it can be used to reestablish the basin aller the next watering, " Place 4 Inches 01 course wood chip mulch within the basin to reduce water loss and stabilize soil temperatures. " Stake trees for only two seasons;part of the staking process Is to determine which trees ac- tually need to be staked. . Staking and guying are not to involve any mate- riallhat might Cut Into the tree trunk such 88 as wire, rope, or lWlne even when placed Inside a rubber hose or over a soli wrapping. . Slaking and guying wiD only involve Ihe use of strapping materials lhat are three Inches greater In width. . Straps will be allached to guy wires only through grommets, or other means that will not allow the wire to be wrapped around the Iree. . Trees 01 less than 3 Inch caliper should be fas- tened to one or more 2x2 wooden stake(s) with a strap thatla placed into a ligure eight forma- tion around the tree and stake, Straps should be fastened directly to the stakes, . Trees that are over 3 inch caliper should be fas- tened with three guy wires, AIi guy wires must be flagged in no less than two locations to make each wire more visible, Stakes should be no higher than the strap, which should be below center 01 the tree. " AIi deciduous trees planted In late summer or lall should be wrapped with a commercial tree wrap Irom the base 01 the tree to the second main branch, Tree trunks should be wrapped lor only two winter seasons (October-April) aller initial planting, Wrapping protects against sud- den temperature changes and sun scalding. It is not necessary 10 wrap corky bark species such as aspen, birch or burr oak. The wrap should be started at the base and overlapped 30% to 50% to prevent water Irom entering and being trapped next 10 the bark. " Tree wrap will be fastened with a staple, tack or some other means that will do Iitlle or no dam- age to the tree; absolutely nothing should be wrapped around the tree 10 secure the tree wrap, . Tree wrap should be removed each spring to fa- cilitate seasonal growth and prevent insect in- festation, ~ 50.
