A vegetable garden is often taken as a sure sign of summer, but gardens can be every bit as productive during springtime. For every garden vegetable that loves the summer heat, there's another that grows better in the cooler and wetter weather of spring. In fact, a number of home garden favorites, like peas, carrots, and broccoli, are early growers that are best planted not long after the threat of frost disappears. Depending on your local weather patterns and climate, cool-season vegetables can be planted either directly in the soil with no cover, directly in the soil underneath a row cover or low tunnel, or in pots and trays in a sunny window or porch. Here are 10 vegetables to plant early in a spring garden.
