This module is a crash course in plant science. Before we get into any gardening techniques we need to first understand plants and how they grow. This knowledge will help answer a lot of the questions that come up in your garden throughout the season. This module is about laying the groundwork.

In the last module, we explored the structures and processes involved in plant reproduction. In this module, we’re going to continue that exploration and move on to how gardeners use these processes to grow more plants. We'll also look at how plant breeders use natural plant reproduction processes to create new varieties (a.k.a. cultivars) so gardeners can grow plants that have better flavor, better color, more disease resistance, and so on. We’ll also look at how to grow plants from seed. Growing plants from seed is one of the most fundamental gardening practices. You'll learn about the biological processes involved, as well as techniques to encourage success. Beyond seeds, you’ll find this week that quite a few plants can also reproduce asexually, or vegetatively. You’ll discover some of those structures and processes, and explore ways that we can grow many new plants from one.
