A fir tree has soft needles, a graceful appearance, a strong root and anchorage system and they also have fewer problems than many spruce and pine trees. More and more dwarf firs are being introduced now into the market. They are the perfect choice for a smaller lot. One of my favorite trees is the white fir. Probably the most adaptable fir, it tends to be a bit more forgiving.
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.
