The info you provided is correct, but if you have a strong worm population and little humus in the soil, you''ll end up with a lot of worm eaten pieces. Which does make a lot of new tubers.
These plants like sun, the more they have the happier. Heat doesn't bother them as long as they aren't bone dry. They do need moisture in drier places.
Mine are raised at 6250' and in both set downs and raised beds. The setdowns are used to harvest water
off a barn roof and driveway and at the same time keep my j-chokes very happy. Also use those setdown locations for windbreaks for other crops. Windbreak and water harvesting are important here as we are pretty dry with 12" precip or less a year.
