Planting Instructions: Planting Instructions: Select a sunny location and plant in early spring in deeply cultivated, moderately rich soil. It does best in deep, moist, rich loam, well fertilized, but will grow in any good soil except perhaps very light sands and very heavy clays. Shallow soil will not serve since this plant has rough, pronged roots. Dig a hole 3-4” deep. Place the sets in the hole so they are just below ground level and cover with soil. Pack sets firmly and apply a balanced fertilizer two to three times during the growing season. Water regularly. Plant in the spring, after the ground warms to about 50º F.
