The Amorphophallus Konjac is a delicate perennial. The tuber is generally dormant when planted. At the end of each growing season, the plant stalk dies down. The nutrients and water stored in the plant goes into the tuber for dormancy. Around the month of April, the tuber will usually form some growth.(Usually an indicator to plant)
The tuber will grow most efficiently in a pot.
Well drained soil will work best.
A mixture of potting soil and 10%-20% sand works best. (This allows for good drainage)
The tuber should be planted at the end of April, beginning of May. (Depending on if it's a late winter)
The tuber should be planted 3-8" under the soil.
The plant will grow best in partial sun to partial shade.
The tuber should be watered lightly until the plant starts to appear.
When the plant becomes visible, it needs to be watered at least once a day to allow for rapid seasonal growth.
The tuber can grow 1-3 times it's size in one season if properly cared for.
If the plant is not hardy for the particular zone (below 6a), the tuber must be dug up after the first frost.
The leaf will die back and the plant will become a tuber.
After the tuber is dug up. It should be stored in a cool dry place indoors.
