Hello and welcome fffuuudesu,

Probably would get more responces if you started a fresh thread for your question, but it did give backround to your question so who cares?

Yea you can bury the plant up to it's ears. The stalk will simply send roots out from it and become a root rather then a stalk.
Besides helping you get rid of 4" of useless stem, the plant will be happier too.

Don't sweat it. :thumbsup:
