I live in zone 11. My climate is warm Mediterranean. Those plants marketed locally are Mediterranean too. There should be no problem to grow them, I thought, but I was wrong.
First, they are hybrids marketed only with the genus name, so no further classification is given.
The practice: Plant them in fall. Winter rains and declining temperatures will make them break dormancy. Package instructions say soak tubers in water for 24 hours before planting.
The problem: tubers rot. Some rot before sprouting, others rot after sending out their first few leaves.
attempts: i skipped the soaking stage, and tried my luck in the garden. In my latest attempt, I used a fast-draining cactus potting mix.
So far, no progress. My next window of opportunity is in the coming November.
