Latin pronunciation: (hy-DRAN-jee-uh mak-roh-RIL-uh)
Bell-shaped flower clusters are hydrangea's delight. Getting it to bloom, though, is a challenge.
To create new growth for future flowers, cut the plant back after bloom. Feed and water well as new growth forms. In fall, store in cool (45 degrees), dim area. Leaves will fall. Water just enough to keep soil moist. After Christmas, bring into light and maintain temperatures of no more than 55 degrees. Water normally. Mist stem with tepid water. As leaves form, feed and soak with supplement solution (1 ounce ammonium sulfate and 1 ounce iron sulfate in 2 gallons water). Increase temperature to 60 degrees until bloom. During bloom, never let temperatures exceed 70 degrees. Propagate by tip cuttings in spring.
