This species of lumber is best for any type of board or picket fence – as long as the bottom of the picket is not touching the ground. Cedar is a very stable wood. It does not warp, shrink, or check, (split), as pressure treated pine will likely do eventually. Pressure treated (PT) pine boards can warp and shrink as quickly as one month after installation. At 10 years, a fence using cedar boards will have a much nicer appearance, compared to a pressure treated pine board fence.
