Question:
Does the humidity have any effect on Pine Cones and how they grow? Do they grow better in dry, arid areas or in a moister climate. Does the climate have any effect on how many pine cones are produced or their shape?

Replies:
Different conifer species (including pines) have differing habitat requirements (i.e., grow better in different geographical locations and with varying soil, nutrient, and water requirements). Cone crop production is affected by many factors besides the climate and habitat including periodicity (i.e., some years have larger cone crops), tree age, pests, disease, and predators.
