Planning You Garden for Seed Saving
2026-03-02 17:30 - 19:30 | Columbia County OSU Extension Office, 505 North Columbia River Highway, St Helens, OR, 97051, United States
Monday March 2nd 5:30 pm
Columbia County Extension – 505 N Columbia River Hwy St. Helens, OR
Presented by Amy Corris
Amy is an unapologetic plant nerd who believes every seed has a story. She teaches about seed saving as both an art and a small act of optimism for the future. She believes good gardens are grown with curiosity, generosity, and a willingness to experiment – and she’s never met a seed packet she didn’t want to open.
The art of saving seeds begins when you plan your garden. This workshop will help you learn about the pollination needs of your plants and help you meet their needs in order to provide heirloom seeds for future gardens.
