Barbara, the other thing about amaryllis is that they may have been forced to bloom outside their regular season, the first time they bloomed. Sometimes after forcing, it takes a year for a bulb to recover and bloom at the right time. Here in Florida they bloom in springtime, March or April. Then we just leave the foliage for the rest of the year to re-form the bulbs for next spring.
If yours are planted in your garden, then they need a little fertilizer and regular water through the hot summer months after blooming is finished. It rains here through the summer, so that part is easy for us, but where you are, not so much. Come to think of it, your drought situation might be a part of the reason why they didn't bloom this year. Not enough water last year?
As Lin said, don't remove any foliage unless it is yellow or brown. Green leaves are making the plant produce a good bulb to bloom the next season.
