Start your garden early by sowing seeds in containers indoors. Any container that drains well can be used, but many gardeners prefer peat pots or pellets placed in flats or plastic flats with many sections that are sold specifically for the purpose. Either way you choose to do it, you will gain many valuable advantages from growing your own plants from seeds. You get to control all the growing conditions, which can create plants that are healthier and more robust than those purchased in stores later in the season.
