When planting Eremurus bulbs, dig a wide hole, enrich with compost or other organic matter and create a mound in the center to hold the bud, pointed end up, at a depth of 2-3 inches. Carefully spread the roots around the mound and cover well. To ensure good drainage, plants may be planted in a raised area, above grade by 2-3 inches. Place tubers 1-2 feet apart. Plant in a row or in groups of 5 for maximum impact. Water well, gently soaking the soil. Provide consistent water through the growing season, after the plant goes into dormancy, watering may be reduced. Once established, Eremurus is quite drought tolerant.
