How often do fir trees produce cones?
The male cones are formed in the spring near the branch tips and are short-lived. Female cones are produced the following summer and are not fertilized until the spring of the next year. A fir tree may be 8-10 years old before it starts to produce cones. Some years it will have far more cones than others. This is in response to environmental conditions such as weather, a stressed tree makes more of an effort to make sure it reproduces before dying.
