B) (Yeats planting area for each plant and excavate pig C) Place planta to pit insuring roots are facing completely downward. D) Heel in soil arouond plant and proceec' to next planting location. E) Newly planted plants need to be fastened to the substrate for the establtahment of new roots. � Roots mall be spread in their normal position. All broken a fioyed roots hall be cut off deanly. G The diameter of the pits for all vsyetative stock shall be at least three times the diameter of the root masa. Plant pit wall shall be scarified prior to plant Installation. H Set the plants upright, in the center of the pit. The bottom of the root mass should be reefing on undisturbed soil. I) Place the backfill around the bees and sides of the root mass, and work each layer to settle backfill and to eliminate voids and air pockets. When pit is approximately 2/3 full, water thoroughly bef#3ra placing remainder of the backfill. Water again after placing final layer of backfill. J) Broken or damaged pots will be cut back to undamaged tissues leaving as much green basal ttsaue as possible aboro the roots If more than fifty percent (507n of the plant is damaged then contractor shall replace the plant. Container Stock/ Baro Root: A) Stock shall have been grown in a container long enough for the root system to have developed sufficiently to hold its sob B) Container plants will need to be watered regularly and placed in shady conditions unto planting occurs. together once removed tom the container. C) Bare root plants aro for immediate planting otherwise see D) below. D) If bare roots specimens are not to be planted within four (4) days, temporary holding of baro root specimens are to be covered entirely by a suitable medium (etc. soil, sawdust, mulch or the like) and watered regularly so as to not dry out Plant Locations: A) New plantings shall be located where shown on plan except where changes haus been made in proposed construction. B) Necessary adjustments shall be made only after approval by the owner or the owner"e repreaentatiV& Water: Water shall be potable and shall not contain elements toxic to plant life.
