A. titanum question
I wonder if some growers experienced with A. titanum can share some of their wisdom with me. I have 5 small plants that grew from seeds planted a few months ago. (I live in Honolulu, and the plants are growing in pots outdoors in partial sun.) Looking ahead, I wonder what to do after they go into dormancy.
I believe that in HetterscheidÂs categorization of Amorphophallus, A. titanum would be considered to be in Group II, so the tubers should not be allowed to dry out during dormancy. This is confirmed by Peter Boyce of Malesiana Tropicals, who said in a previous posting on this forum that they should never be allowed to dry out, and watering should be only cut back slightly during dormancy. In addition, Troy Davis, says on his website that in its natural habitat A. titanum gets high rainfall throughout the year, that it should not be taken out of the soil, and that it would not enjoy being stored dry during dormancy.
Since A. titanum tubers are susceptible to rot, after the plant goes dormant, I wonder if I should dig out the tubers, cut off any sections with rot, and treat them with a fungicide. Maybe I should also let them air out for a few days before planting them again. Anyone have any thoughts on this?
