celeriac

Some of my celeriac is producing flower shoots otherwise it is very healthy looking. I keep it well fed and watered. Do I cut off these flower shoots or not?  Same goes for celery...do the flower shoots stay on? There aren't many and I do water them alot. On the same subject, my pak choi is also going to bolt. Should I just eat it...it's already quite a good size but has been munched by flea beetles! That's rather alot of ?'s, should keep you busy in the rainy periods.
