Storage: Store bulbs in peat at 68°F
(20°C). To induce
flowering, the growing plants must receive at least four weeks at 80-85°F
(27-29°C) followed
by a minimum temperature drop of 14°F
(8°C), e.g., down
to 65-70°F (18-21°C).
These temperatures must be very constant or bulbs may not flower. After
12 weeks at the lower temperatures, the plants should flower. Subsequently,
the high temperature treatment should be repeated. Thus, the plants can
flower twice per year. If water is withheld, the foliage will senesce and
sometimes this will also induce flowering. |
