This year's Christmas might be without Christmas trees for some Americans. A fungus called Phytophthora root rot is afflicting trees in Oregon and in North Carolina, affecting nearly all Christmas tree species. Tree farms are most susceptible because of density and the soil is usually poorly drained. What makes this so deadly is that it is difficult to detect, and can only be done through a laboratory analysis. there is also no known cure for the root rot. If this is not contained, more than 304 million dollars could be lost in Oregon alone. The U.S. Department of Agriculture is spreading word of this fungus in order to get firm aware and regularly check their trees.
