Cut it and use it as neccesary. Don't pull it up as it will continue to grow into fall.

Depends on what you planted it for, how you plan/planned to use it. Only for fresh eating, for canning or freezing or dehydrating?

If you like it but only want to eat it fresh then you might as well pull it and replant in the fall. That gives you the best fresh flavor without the bitterness.

If you planted as a green manure for soil benefits then turn it into the soil or toss it in the compost bin.
