What is Bolting? While plants do not “run away” physically, their growth may run away rapidly, and this is basically what this phrase means in the gardening world. Plants, mostly vegetable or herbs, are said to bolt when their growth goes rapidly from being mostly leaf based to being mostly flower and seed based.
What does Herb bolting mean?
Bolting occurs when a plant is stressed, often because the temperatures got too warm for that plant’s liking. The plant wants to reproduce before it dies, so it sends up a flower that will go to seed. Bolting diverts resources away from the leaves, which can affect the taste — and not in a good way.
