How to collect seeds from Birch trees

Asked September 27, 2020, 8:32 AM EDT

I have a birch tree in my yard And I would like to gather seeds. It’s late September now, the tree has green catkins on it. Do I pick these now? Can you send me a site that I can read that will help me in this process.

Growing a paper birch from seed is a great idea. The pieces you collected appear to be strobiles, or fertilized flowers. When they begin to dry you can harvest the seeds. Here is a link to a picture:
