Few garden activities are as satisfying as harvesting root crops. Grasping the green aboveground shoots and pulling to reveal the treasure beneath the soil -- this is one of gardening's finest moments! And root crops are easy to grow in loose, well-worked, rich garden soil. Direct-sow the seeds in early spring or late summer, for these are cool-season crops, maturing in the chilly weather of spring and fall. And enjoy your "hidden" harvest of nutritious, delectable root vegetables!
