Here in Iowa and in most of the eastern 2/3 of the US it is a superior windbreak tree and I highly recommend it. Spacing- single row 20’ apart, double row 20’ by 20′ apart, multiple rows 25 ‘or more apart with the trees staggered from the other row. Fungal diseases that effect other spruces do not effect it, and insect pests occur rarely except on older or stressed trees.Ī 2’ tall potted tree can be over 10 ft tall in 5 years, in good soil, with adequate moisture and weed and grass control around the base. They Norway Spruce have few disease problems unless stressed. In areas where the summer can be hot and dry (Nebraska, Montana, Wyoming) they will not do well unless they have adequate moisture, for best growth rates they should have 25” of rain per year or more. Does not do well where the soil is constantly wet or swampy. It is able to take more moisture than other species and should be considered where soils can stay moist and where the land is level and does not drain as well. They will grow in a soil PH of up to 9 but does prefer a 7.5 and lower for best growth rates. I have seen them growing in a variety of soils, even rocky, and sandy soils that hold moisture, and does well in clay soils where pine and fir would not do well. It will grow well in hardiness zones from 2-7 with some sites in the southern areas being too warm for this spruce as they enjoy colder climates better. Deer will not normally eat this species unless there is nothing else available.
It has bright-green foliage when young that changes to a glossy. Due to its shape, heavy snow and ice storms cause little damage. The Norway Spruce evergreen is a rapid grower with drooping, pendulous secondary branches. It can live a very long life in windbreaks of over 100 years in most soils, and is the most common old windbreak tree in the midwest. It will grow to 100+ ft tall and 25+ ft wide, it is very wind firm due to its large spreading root system, and tough flexible wood. In Europe it is commonly called the Mountain Spruce and can be seen growing everywhere.
It is a native of Europe where it grows throughout the region and is the most common evergreen in the Alps area in Europe, the Black Forest of Germany, and the Carpathian mountains of Romania and Ukraine. Its branches extend to the ground, giving excellent wind protection. It never drops its needles but keeps them on for up to 10 years. The Norway Spruce is a fast growing (2-3’ per year) evergreen that has dark green needles that are 1 inch long, and can grow up to 5 ft a year in a good weather year. abies seedlings include a number of parallel physiological and biochemical changes in concert, enhancing the capability of plants to survive and grow during drought periods, but only to a point.The Norway Spruce is our favorite and best large evergreen for windbreaks in the eastern 2/3 of America. These results demonstrate that the drought response of P. A significant decrease in Chl(t) and F(v)/F(m) were only observed during the more advanced stages of dehydration. Decreasing values of water potential were accompanied by early changes in P(N), g(s) and Pro. On Day 26, significant differences in psi(L) were recorded among all treatments. After Day 12 of dehydration, psi(L) of ss seedlings was already significantly lower than that of the two other groups.
The results indicate that not all observed physiological parameters display the same degree of sensitivity to dehydration.
The following physiological variables were monitored until ss seedlings began to die: leaf water potential (psi(L)), stomatal conductance (g(s)), CO(2) exchange (P(N)), free proline content (Pro), total chlorophyll (a + b) concentration (Chl(t)) and the maximal photochemical efficiency of photosystem II (F(v)/F(m)).

Image of seeds, christmas, growth - 86262650. The seedlings in the control group (c) were watered to prevent any dehydration effect. Four-year-old seedlings of Picea abies Karst (Norway spruce) were grown in semi-controlled conditions with three watering regimes.
