They may be the Plain Jane of the kitchen garden, but homegrown Turnips are wonderful when enjoyed small, 3" maximum. Sow in the spring as soon as the soil can be worked in an area which has not been freshly manured. Harvest by gently pulling out by the bottoms of the greens. Turnips are great in their raw state - munched whole, sliced or grated in salads, or steamed and dressed with butter. Turnip greens are delicious too!
