August and September are the main seasons for when western white pines become ripe. When the cones are ripe they will turn a yellowish color. At the age of 7 the western white pine is able to produce its cones, and it can keep this process up until its 70 years old. But once over 50 years of age it gets harder for the tree to reproduce, and the only way it will still reproduce is if the trees individual tree vigor and ability to set or bear cones. The cone beetles are the trees worst fear they can cause practical to almost complete failure in the cone production. There are also moths that can cause a loss in seed growth. The seeds can survive harsh conditions when off of the branches of the western white pine; they can still be useable even after a whole winter. Studies found that you can keep the seeds viable for 20 years off the branch if you store them at -18C (0F) to -15C (5F) | August and September are the main seasons for when western white pines become ripe.

Seedling Development-''' | '''Seedling Development-'''' | ||
For germination to occur the seed must go through 30-120 days of cold temperature. The seed coat controls the dormancy the most. The seeds will most likely germinate in the late spring, the germination in lower elevations germinate in late April. The trees in the higher elevation will not germination if you increase the sunlight on the cone scientist have found that the soil is controlling center in the beginning for germination. Seeding off of the pine tree usually die because of insects and diseases. | For germination to occur the seed must go through 30-120 days of cold temperature.

'''Vegetative Reproduction-''' | |||
The Western White when naturally reproducing it does not use sprouting or layering, it does not use sprouting o layering. You can just take the cuttings from the tree and plant them and except it to reproduce you has to get the cuttings from the needles and wait for roots, you also have to use rooting hormones. | |||
