Hello!
Many types of
trees in that family can sprout and
root under similar conditions. Just to be safe, I would season the wood
enough that it dies on a cellular level before burying it, if invasive sprouting is a possibility. Maybe before you bury it, make some
mushroom totems with the rounds, and let them go for a year before you bury them. Then you can get a mushroom harvest before they become part of your
hugel project.
Hope that helps!
