Starting Seeds Indoors

Transplants can cost four or five dollars a plant, which means that in one growing season you’ll make back your investment in seed starting equipment. To grow strong, healthy seedlings you need a seed starting tray, a heating mat (to keep the soil warm and discourage damping off fungus), and a light source. It really does make a huge difference in plant vigor when seedlings get plenty of strong overhead light, rather than weak sunshine coming through a window.
You will also want a light soil, good for starting seeds.

Radishes are one of the easiest cool weather vegetables to grow, and don’t require starting indoors. Watermelon is a tasty and beautiful variety, adding color to spring salads. You can “winter sow” cilantro seeds now wherever you have room in a sunny border or vegetable and they’ll sprout when it’s warm enough to grow. Lacinato Kale is a nutritious, easy to grow green that is at home in the flower border as well as the vegetable garden. You’ll have the best luck if you start this indoors.

Seedling Heat Mats prompt seeds to germinate and grow faster and ideal for starting seeds indoors.
