Contractor shall in a final Xx. From planting detail. Remove entire non bi.odegradable wrap material or remove minimum 1/3 of top of the burlap and cord. Plant root collar at soil surface, even if this requires removing some soil from top of ball. SPECIES SELECTION. These are observations assume a clay soil with little or no organic matter. Note that all of the species do poorly in compacted soils and soils with no organic matter. Adding fertilizer is only a partial substitute for adding organic matter +White pine may not be appropriate to the site. White pine does not grow well in clay soils. White pine does not grow well in soils with pH greater than 6.5. White pine is intolerant to soil compaction. If the pine does not prosper, it will not provide the desired winter barrier between the club and the neighborhood. On the other hand if the white pine grows rapidly when juvenile, a single stem does not provide much visual screen. + White spruce is listed on the plan and Black Hills spruce in the list, and the plan takes precedence. Of the two white spruce's black hills may be more suitable to the site. BH spruce is more tolerant of alkaline soils is more drought resistance. But difference between these two varieties may be focused on which is known to be more resistant to Rhizosphera. +Red oak. Red oak becomes iron deficient when grown at pH above 7. Iron chlorosis requires periodic treatment. Red oak is intolerant of compacted soils, +Alternative conifers that could be considered include Austrian pine which is at least moderately tolerant to compaction and clay. Its disadvantage is susceptibility to Diplodia shoot blight. If Norway spruce is not susceptible to Rhizosphera, it might be a good spruce to include. However, it is sensitive to Ceratocystis and to compact soils. Perhaps a more heterogenous spatial mix of different species is a good defense against all of these pests? POSITIONING OF DIFFERENT SPECIES may adversely effect the conifers, which are the main source of the year-round barrier between the club and the neig h borhood. +Dogwood next to the white pine has a biological draw back. Once the dogwood becomes established it might shade out the lower branches of the pine. Next to the spruce it would also raise the humidity and lessening wind flow through the trees increasing the incidence of Rhizosphera needle. drop, further. In short the dogwood could cause loss of leaves and hence death of lower branches. in small trees it could have similar effects on large branches. This same would be true for any shrub that is shade 3
