Hello, I planted my newly-aquired Helicodiceros tuber last fall in barely moist soil. I waited about a week and then watered. I watered about once each two weeks all winter, and nothing happened. We had a cold winter for Phoenix, with about 20 nights at my house below freezing. The following days are always well above freezing. Two weeks ago our weather suddenly went from 45 degree nights / 65 degree days to 65 degree nights / 90 degree days. The plant sprouted and is growing. Is this unusual behavior? Leo -- Leo A.
