    Start by comparing the needles. Pines tend to have longer needles than spruces and these grow in pairs or clusters. Spruce trees needles appear to grow directly from each branch and are spaced close together, like bristles on a hairbrush.

    This depends on which pine tree you are talking about. All pines have needles with scratchy bark on the trunk, but each tree shape is different. Some grow tall and straight like a needle, others like round baubles and others like triangles. Search for image examples of pine trees for a good idea of the wide variety.

    Under certain conditions that put stress on a tree, it will not produce cones in a stressful year. That stress can be caused by temperature fluctuations or drought conditions or lots of other things.

    How do I identify a white BC pine vs a Ponderosa pine?

    Ponderosa pines are easily recognized by their tall, straight, thick trunks, clad in scaled, rusty-orange bark that has split into big plates. One can easily identify some trees by smelling their bark. Ponderosa pine bark smells like vanilla or butterscotch.
  • Question
    Pine needles are grouped in five, indicating a white pine, but bark is 1 - 1½ squares, which does not appear smooth like a white pine. Are five grouped needles always indicative of white pines?
