More Easy Vegetables to Grow. Most root vegetables like carrots, turnips, and radishes are hardy and can be planted directly in the garden early in the spring and left until fall. The tops can be harvested too as these plants grow. Green beans and zucchini are also a cinch to grow and quite prolific producers.
Carrots, beets, parsnips, radishes, turnips, and rutabagas are the most commonly grown root crops. They all have similar cultural requirements and grow best in cool weather. Since they are hardy, they may be planted early in the spring, and left in the garden until fall. In addition, tops of beets and turnips are commonly used as cooked greens and can be harvested while the plants are young.
