Retarding Needle Fall on Black Spruce Christmas Trees
Christmas tree purchasers often believe that their money has been ill spent because the trees so quickly shed their needles. The authors show how through the use of ordinary tap water without the addition of any expensive chemical, needle retention may be materially promoted. Although the experiments dealt only with black spruce, the method should have application with other species that are prone to lose their needles quickly when brought into a warm room.
