You'll probably have the best selection with online seed companies (try: Sustainable Seed Company, Baker Creek Heirloom Seeds, or Johnny's Selected Seeds), but your local garden center will likely carry them in the spring, says Myers. Once you've picked up your containers and soil for your indoor garden, it's time to choose your seeds. Step 6: Plant those seeds, transplants, or scraps. Nitrogen is the key nutrient for plant growth and helps create lush, green leaves, which then help capture the sun's energy, convert it to sugar, and ultimately create delicious vegetables, per the Northeast Organic Farming Association."It reduces your workload, and I am all about that," she says. If your chosen potting soil doesn't contain fertilizer from the get-go, consider adding one that contains the right amount of nitrogen for vegetables plants (which need less than leafy plants and grass) and slow-release to provide a steady flow of nutrients. Some boast a "starter charge" of fertilizer that's used up after two or three waterings, while others, labeled controlled-release, time-release, or slow-release, include a fertilizer that provides small amounts of nutrients over a long period of time, explains Myers. Aside from good 'ol dirt, potting mixes may contain fertilizer, so be sure to check the bag, so you know how often you should be fertilizing. When choosing a potting mix, look for one that's light and fluffy, and if you're going for organic veggies, use a mix that's certified and labeled by the Organic Materials Review Institute, says Myers.
