Step-by-Step Growing Guide
Epazote (Dysphania ambrosioides, formerly Chenopodium ambrosioides) is a robust, adaptable herb that grows almost too readily in warm conditions. It thrives in well-draining, lean to moderately fertile soil with a pH of 6.0–7.5 — poor soil actually concentrates the essential oils responsible for its characteristic flavour. Direct sow seeds shallowly (barely cover) in full sun after the last frost when soil is warm. Germination is rapid at 20–25°C. Thin to 30–45 cm apart; epazote grows to 90–120 cm and spreads vigorously. Water during establishment then reduce — established plants are notably drought-tolerant. Do not feed with nitrogen fertilisers; this dilutes the intense flavour. Contain carefully as epazote self-seeds prolifically and can become a persistent weed. Growing in containers prevents unwanted spread. In frost-free climates, it persists as a short-lived perennial though fresh annual plants from self-seeding replace the parent plant naturally.
