Great looking bulbs, Barbara! I assume you know to pot them up now in pots that are just a bit larger than the diameter of the bulbs. Terracotta works best because they become top heavy when they develop leaves. After potting, they need only one good thorough watering to trigger the flower development, assuming they received proper prep in the past year.
Amaryllis are really quite simple to get to bloom every year if you do the following:
After flowering is finished, cut the flower stalk down but leave the leaves in place. Move it to a sunny location so the leaves receive maximum light. Water when the top quarter of the soil is dry. They can be moved outdoors when temps are consistently above 55 degrees.
Let them grow all through the summer, fertilizing monthly. In early September, force them into dormancy by moving them to a dry, cool, dim indoor location. With total neglect, the nice healthy leaves will gradually yellow and die. They can then be cut off. Maintain them in this dormancy for 8 to 10 weeks. Then, bring them to a nice living room location and water them thoroughly once and they should respond accordingly.
As long as you honor their need to have the bulbs replenished throughout the spring and summer and their need for dormancy in the fall, you should have success.
You may want to look into White Flower Farm in CT. They have absolutely top quality plants (Including Amaryllis), superb instructions and helpful personnel. Yes, they are expensive but well worth it if you can afford them. Visiting them in May and June is a wonderful experience!
