Course description

Seed Saving is an empowering skill that supports self-reliance and helps to promote biodiversity while providing the gardener with plants well adapted to local conditions. In this course, we review botanical reproduction to deeply understand the processes involved in seed production and then look at the techniques used to harvest and save medicinal plant seeds. Finally, we review germination to complete the full cycle of working with seeds. 

After completing this course you will have all the knowledge needed to effectively save your own seeds. You will be able to harvest seeds from many types of plants and will understand plant reproduction, enabling you to skillfully select the best time and method to save seeds.

During the course, we summarize seed saving techniques in a concise set of instructions. We also look in-depth at each step. You will gain an understanding of the best timing for harvest, methods for harvest based on seed type and shape, and how to select the best plants to save seeds from. Additional skills taught include drying seeds, storing seeds, testing saved seed, and germinating your seeds when you are ready to propagate new plants. 

To give you a thorough understanding of seed saving, we review aspects of plant reproduction and botanical anatomy that relate to fertilization and seed production. This includes the anatomy of a flower, anatomy of seeds, and various types of seeds and fruits. Understanding flower and fruit anatomy give us the knowledge needed to harvest seeds in a way that ensures our seeds are viable for future use. We look at 5 common families of widely used medicinal plants and learn about the unique features of each family’s fruits. 

We also discuss plant physiology and processes related to seed production and use, including plant life cycles, pollination, seed dispersal, and germination. In regards to pollination, we talk about open-pollinated and hybrid plants and discuss why and how a gardener may prevent cross-pollination. 

In addition to the practical skills that comprise the focus of the course, we discuss seed banks and seed longevity to understand the importance of saving organic seeds to support food security and maintain our access to valuable medicinal plants.

Upon completion of this course, you will have the ability to:

  • Understand the plant anatomy involved in reproduction, including flower anatomy and how this relates to plant reproduction seed saving
  • Know about different types of fruits/seeds and how seeds are dispersed in nature
  • Comprehend plant life cycles
