Instructions
These are quite easy to grow. Amorphophallus will go dormant
in the winter. Plant the tubers in pots at least 4"
wider than the tuber. The depth for planting the tubers
will depend on its size. Small tubers should be buried
around 2"-3" deep. Large tubers around 6"-10".
Use a good quality potting mix. Make sure that the top
of the plant is facing up. When dormant, don't give it
too much water, let the soil dry out. Keep it dry for
a couple of weeks and then water it again. Don't fertilize.
Repeat this process until the tuber wakes up in the spring.
At that time you can start watering regularly and fertilizing
the plant.
In the spring, if the tuber is mature enough, you will
see the flowers, otherwise a leaf will sprout. Very often
they form clumps with the flower appearing between the
leaves. They should start going dormant again in the fall.
The tuber can be dug up by late winter if necessary.
