Bolting in Epazote

verifiedReviewed by the GreenScout Team

Epazote is a pungent Mexican herb with a distinctive, slightly musty flavor used to season beans, corn, and traditional Latin American dishes. Bolting is when a plant prematurely produces a flower stalk and goes to seed, usually triggered by heat or day length. It makes herbs and leafy vegetables bitter and unusable.

How to treat bolting in Epazote

Once bolted, the plant cannot be reversed. Harvest any remaining usable leaves immediately. For some plants (basil, coriander), pinching off the flower stalk early can slow bolting and extend the harvest slightly.
