REAL is the only way to go!!
Of course Christmas trees are what help me to have a boat. My dad started selliing trees when I was about 10 years old. We bought the trees from a guy that was retiring and planted some of our own that same year. So I've been selling Chrsitmas trees every year for 35 years, with no end in sight.
Troutly is right about the Fraiser Fir. That or a Blue Spruce or Norway Spruce are the only way to go. They are the most expensive of the u-cuts because they take longer to grow. An 8' Fraiser or Spruce is 10-15 years old. A lot of things can go wrong in that amount of time.
Anyone need a map to our farm??
