Norway Spruce


The Norway spruce belongs to the family Pinaceae. Spruces are symmetrical and are conical trees. In this family alone there are about forty different specimens. This report will explain the growth, culture, diseases and insects the plant may get, some propagation techniques and the landscape uses it has to offer.

The Norway spruce can grow from forty to sixty feet high and have a spread of twenty five to thirty feet. The zone it can survive in between three to eight. The bark on the Norway when it is young is thin, but can become thin with gray brown flaking scales on the bark off older trees. It’s pyramidal with pendulous branches. The fruit are cylindrical cones can get to a purple or green color when young. Foliage around the medium grade of the tree and the leaf color it offers is bright green to a purplish color when maturing. A culture it has to live in order for it to survive is moist, sandy, acidic, well drained soils but can survive in most soils around the specific zones. This plant prefers the cold climate and should be pruned in the spring. Examples of select diseases and insects that affect spruces include red spider, spruce gall aphid, bud worm, and borers. The Norway Spruce are often used as windbreaks and are used a lot for large scale landscaping such as parks, golf courses, highways, and public buildings. One of the benefits of propagating Spruces is that the seeds germinate without pretreatment and can be directly sown in to the grown. Root pruning is optional and should be performed between from November to January.

The Norway spruce can be beneficial for decorative purposes and for weather preventative cases such as wind-breakers. Planter’s can benefit from this because they are not pretreated and can be directly sown in the grown and root pruning is optional so there is less maintenance.

This report mentions important facts about the plant that landscapers can use to their advantage. They will also learn some background information about the plant including where it came from and what zones it can be found in and survive
in.

  1. Disease is caused when the normal growth of the lawn Lawn is disrupted because of its interactions with pathogens like fungus. The pathogen comes from the environment and hinders the growth of turf grass. Diseases generally occur where the environment is floods with pathogens. Moreover the plants which are more stressed are prone to disease as compared to unstressed plants.
