If you live in a cold climate, your growing season is limited to the number of days between the first and last frosts of the year.
For the most part, vegetables don’t grow in freezing weather. If you live in a cold climate, your growing season is limited to the number of days between the first and last frosts of the year. Starting seeds indoors allows you to extend the length of your growing season, so that you can grow more food. In spring, seeds can be started indoors several weeks earlier than they can be planted outside. When air and soil temperatures warm up, you can transplant weeks old seedlings into your garden at a time when you would otherwise be sowing seeds and waiting for them to germinate.
