I'm a little surprised by this and agree with what Mike (meizzwang) said. I'd suspect the wet cold roots/corm is the problem. Planting on a mound like they do with avocados, in a spot with full sun all day in winter might be enough to turn things around. Or even a very large pot (minimum 25 gallons) placed on soil and allowing the plants to root through the pot into the soil. That would guarantee you could keep the corm and some of the roots pretty dry during the cold rainy season. With the almost complete lack of rain this year, in-ground might have been OK!
