Weeds
The types of plants considered weeds in Christmas tree cultivation vary from region to region. Regardless of the types of plants, from herbaceous weeds to woody plants, weeds are considered a pest to Christmas tree farms for several reasons. Seedlings are vulnerable to the competition for water and nutrients presented by weed infestations, however, even established trees can be out competed by weed growth. Some specific weeds cause more serious problems, the bracken fern can increase disease in fir trees, and employee morale and efficiency are decreased when weeds such as poison oak, Canada thistle and wild blackberries infest plantations. In addition, excessive weed growth can provide cover for wildlife, such as deer, gopher and field mice, which can have damaging effects on Christmas tree crops.
