Answer: Forcing bulbs can be tricky and sometimes it takes some trial and error to make the process work. In this case I think the chilling temperature was a little too high; normally a temperature closer to 40 degrees is recommended for two to three months. Then the growth period might have also been a bit too warm, since the preferred temperature range for that stage is only about 60 to 65 degrees. The cooler temperature will also help the blooms last longer. Finally, some varieties simply are more amenable to forcing than others.
