(1)Center the plant holes at the lo cation stake, unless the engin eer allows otherwise.

(2)Excavate the plant hole, except for MT stock, to at least the minimum dimensions the plant data chart

included in the plans show or as the engineer directs. However, the minimum diameter of the plant hole must be at least twenty-four inches greater than the diameter of the ball, container, or roots, for the full depth of the plant hol e. The depth of hole shall equal the height of the ball, pot, or container, so that the plant root collar is at ground level when the plant is in its final position and resting on undisturbed ground. Except, if placing the plant in heavy soils , then make the hole deep enough so that the plant root collar is 2 inches above the ground level after planting.

(3)Unless soil conditions make it impossible, dig the planting holes for MT plants by the tree-moving

machine and make them approximat ely the same size and shape as the soil mass containing the root system of the machine moved plant.

(4)Keep the sod and topsoil suitabl e for backfilling separate from the excavated subsoil.

(5)If planting on a slope, measu re the minimum depth of the plant hole from the downward side of the

slope at the hole.

(6)If it is necessary to suspend planting operations until the fo llowing planting season, backfill any open

plant holes before suspending the work. 632.3.5 Pruning

it in a vertical position. Spread the roots of BR plants to the ir approximate natural position and prune as required. Place B&B plants wh ile in their wrapped ball. Move and handle only by the ball. Set the plant so that, after settling, the plant root collar is at or 2 inches above the surrounding ground level, as specified above in 632.3.4 .

(3)Unless specified otherwise, ba ckfill the plant hole with topso il composed of 6 parts soil to one part

compost by volume. Place this so il compost mixture in layers around the roots or ball. Carefully tamp each layer in place in a way tha t avoids injuring the roots or ball or disturbing the plant position. Remove the burlap and other wrapping materials from the top one -half of B&B plants. Once approximately 2/3 of the plant hole is backfilled, fill the hol e with water and allow the soil to settle around the roots. After the water is absorbed, fill the plant h ole with topsoil and tamp lightly to grade. Bring any settlement to grade with the topsoil.

(4)Fill holes made for MT plants to about 1/2 the hole depth with slurry made from a 1:1 mixture of water

and compost by volume. Place the sl urry in the hole just before placing the tree in the hole. After removing the machine, backfill any voids remaining with topsoil . To facilitate watering, auger vertical holes around the perip hery of the tree just inside the ball lim its. Space the holes equally a maximum of 4 feet apart. Make each hole dee p enough and large enough to ac cept a perforated pipe 42 inches long with a 2 inch inside diame ter. Insert the per forated pipes into the holes immediately after augering. Make the top of the pi pe flush with the top of the mulch once in its final position. Leave the pipes in place after the tree is established.

(5)After the plantings are in place at least 2 days, but not more than 5, inspect the plantings. Adjust plant

depth and plumb as necessary, and place all additional required backfill. During the inspection period, thoroughly water all inspected plants and remove all twine or r ope and labels attached to trunks or branches. 632.3.8 Fertilizing
