<br />It :s believed that planting the trees at the start o'' the first <br />sprrng following grass and forb seeding :s useful as it allows grass <br />and forb seed to germinate and Gass through the cotyledon stage before <br />the minor d-sturbances that occur during tree planting. This also <br />allows the trees tc become established :n the frrst year without <br />e,,cessr:e moisture ~ompetrtion from the grasses. <br />No irrigation or shingle protection is considered necE~ssary to <br />establish the trees. On the Visual Berm 450 trees and shrubs were <br />planted as bare root stock. No irrigation or protection w:is provided <br />and only one fertilizer tablet was placed in the planting prole. After <br />6 years, appror.imately 60 /. of the or>ginai planting is still alive and <br />all but a halt dozen or so are strong, healthy plants, somea having <br />reached heights of nearly 8 feet. Those areas are east facing whereas <br />this area is north facing. It is well documented that trees growth, <br />keeping species constant, tends to be strongly controlled try aspect. <br />This is only mar-ginally true of grasses, fortis, and most shrrubs. <br />Fertilization of the trees will be limited to the inclusion of a <br />fertilizer tablet in the bottom of the planting hole plus ~~ossibly the <br />application of Hiosol organic soil amendment to the top of the <br />planting medium. It is also possible a small amount of po:.yacrylamide <br />will be included with the planting to help counteract the effects of <br />dry periods, but this may be limited to only sites where dryness is <br />expected. Polyacrylamides show considerable potential for use in <br />revegetatior~, particularly in the elimination or reduction of a need <br />to use irrigation. However, the verdict is still out as to exactly <br />ho~.: use`_'. .~ is in plantings on semi-ar_d :and.
