Growing Clivia and Getting It to Flower

I have an 8 year old Clivia miniata. It has not bloomed in the 3 years I have owned it. What do I need to do to get those beautiful orange flowers?

A healthy slightly potbound clivia will reward you with beautiful flowers. Be sure your plants receive bright light indoors or partial shade outdoors, ample moisture, and high humidity during the summer. Keep the plants in a cooler location (mid 50’s) during the winter. Reduce watering and do not fertilize during this period. As the days lengthen, increase the moisture and fertilize as needed with any dilute solution of flowering plant food. The plants should produce flowers in spring or summer. This plant is hardy in zones 9 or 10 and higher.
