Here in the UK, pine cones grow on several types.
Cones: White pine are monoecious, meaning each tree can produce male and female cones. This occurs in the spring, typically between May and June. Male cones have overlapping scales that open to release pollen. Female cones can be up to 8 in long and one inch in width. Feb 26, Because sap is like the engine that keeps nourishing ingredients running throughout the tree, small amounts of sap may ooze all year from pines. Usually that happens after they’re pruned, when they begin budding or as the seasons change.

Apr 28, Cones, such as found on pine trees, serve to protect the developing seed. Sometimes too, pine cones function in dispersal of the seeds. Because of their often large sizes, it takes a lot of energy (photosynthate) to make a pine cone. Thus, if there were no seeds inside, it would be wasteful for the plant to expend energy to make large cones. May 25, If the tree looks otherwise healthy and other trees in the vicinity also look like they have a lot of cones, my guess would be that it is just a good cone year and that you will see lots of both immature and mature cones on the ground through the course of the season.
