Starting seeds is the inexpensive way to grow more of your favorite plants. Here’s what you need to know for success.
Starting plants from seed has many practical benefits: You save money, get a head start on the growing season, and choose from varieties far beyond those locally available. By starting seeds, you also get to experience the joy of watching a seemingly lifeless seed sprout into a living plant.
A seed is a plant embryo and its initial food supply is stored within a protective coating. Seeds remain dormant until a combination of moisture, temperature, air, and light triggers germination.
Seeds have different shelf lives. Some will remain viable for hundreds of years, whereas others may only store well for a couple of years.
