Good morning, Susan! Helicodiceros needs lots of sun to bloom. They also love fertilizer. W hen they are growing, I keep mine in full sun. I repot every other year a fter they go dormant. The media I use is peat/sand/pumice (grit) with lot s of dry compost/leaf litter mixed in. During dormancy I keep them comple tely dry. When they break dormancy, I give them lots of water (I leave th em out in the rain, and if there is no rain I do not let the soil complet ely dry out), but I never let them sit in water. They must be well draine d. Using these methods each plant gives me anywhere from one to three inf lorescences per year. Happy days! Christopher D.

Subject: Re: [Aroid-l] Temperature requierements for Helicodiceros Bernhard,
I am certainly no expert when it comes to this plant, but I do have a few in pots, so I will share what I know! Here in Tennessee, USA, they start growing in December and die back in hot weather, but I thin k they last until June or July.
My pots were under a potting bench, getting almost no light and only a little water dripping from the pots above. I pull them out when I notice them starting to grow.
Mine have never bloomed, however.
They are in a greenhouse that gets down to about 50F (10C) at night an from 50-100F during the day (depending on outside temperature and sun) ..

Date: Wednesday, January 27, 2010, 4:28 AM Aroiders, from the temperatures and seasonal rainfall on Sardinia I g uess that Helocodiceros grows from late Sebtember to April or May with the maximum of rainfall in November and December and temperatures down to 8 °C (46 °F) in December to February. I woul d like to know, wether the low temperatures in the growing season are n eccessary or if Helicodiceros could be grown (and flower) at higher tem peratures as well. Looking forward to any comment, B ernhard.
