Hi Rand and all,

If you don't have a greenhouse, put the pot of Ferraria in the
brightest, sunniest window you have.

Good luck on trying to switch them over. My only thought on the
subject would be to store the bulbs next summer and autumn for as
long as possible out of the pot, bare, and in a brightly lit, warm
and quite dry location to delay the new shoots.

Some bulbs are very sensitive to environmental conditions and come
in and out of dormancy in response to moisture, daylight length,
heat, cold, etc. Others seem to have a built-in calender and clock
and grow on their own timetable regardless of conditions around them.

Regards,
