Some firs are quite picky about where they are grown, and in what type of soil. White firs can be grown in most soil types, although like most trees, they prefer it well-drained. White firs are somewhat drought resistant and have even been known to grow out of cracks in granite rock or in old gravel pits, Goodspeed says. In an area where only Mother Nature waters, a white fir usually can survive just fine. They get their name from their light-colored needles.
New growth is a nice, light green to blue color, which is quite attractive.
They can reach a height of 45 feet, with a spread of 25 feet. Like most firs, they have a pleasing pyramidal shape. The Fastigiate variety has an upright, almost columnar form. Another tall fir that grows in our area is the balsam fir, he adds. These firs are often grown to be sold as Christmas trees.
