My herbs are bolting

Bolting is when a plant goes to seed. Unfortunately, three of my herbs have bolted, leaving the leaves puny and either too strong or too weak in flavor.

I need to deal with these mint seeds before they spread and take over the world.

The leaves are called cilantro; the seeds are called coriander.

Dill eeds are as airy as the dill leaves themselves.
I plan to use the seeds in pickles (thinking positively about my cucumber plants).
