Spurias require full sun and an alkaline soil. Agricultural lime, dolomite limestone, or ground oyster shells may be added to make the soil alkaline. About six weeks after flowering, water should be partially withheld and the plant allowed to go into its natural dormant period. Just enough water to keep the rhizome from drying out should be applied. For better garden appearance, after the foliage starts to turn brown, cut it back to about four inches above the ground. Regular watering and feeding should begin when the new growth begins in the fall. Like all irises, spurias are heavy feeders and an all purpose fertilizer, low in nitrogen, applied three times a year is sufficient. Spurias can be left in place for many years to form large clumps, but if necessary, dig and replant in early fall, being careful not to let the rhizomes dry out.           

Isaiah 40:8
The grass withers and the flowers fade, but the Word of our God stands forever.
