When the plant bok choy goes to seed, do you cut the plant off at the bottom or leave it?

When it goes to seed, this is called bolting. After bok choy bolts, it is considered to be done and the whole plant is harvested, regardless of the size. After it bolts, it will cease to send energy to the leaves, even if you cut the flowers off.
You can help prevent bolting in the future by keeping the roots as cool as possible. Heavy mulching and frequent watering will help with this, but growing it in the cool seasons (spring and fall) will help the best.
