Can you tell me what type of fertilzer I should be using on my amaryllis? I live in Phoenix, AZ and the plants are outdoors in containers, and a few are in the ground. The leaves are healthy but they rarely produce flowers.

Use a high phosphorus fertilizer or bone meal. The phosphorus is what plants use to make the blooms and helps with blooming. Here is more information: https://www.gardeningknowhow.com/garden-how-to/soil-fertilizers/phosphorus-plant-growth.htm
