How to grow epazote
Overview
Epazote is a pungent herb from the Amaranthaceae family, grown for its distinctive flavour in Mexican bean dishes. It thrives in warm conditions and requires regular leaf harvest to maintain quality.
Soil Preparation
Epazote prefers slightly acidic to neutral soil (pH 6.0-7.0) with good drainage. Add compost or well-rotted manure before planting to improve fertility. Avoid heavy clay soils that retain moisture, as they cause root rot.
Growing Guide
Sow epazote seeds 5mm deep in free-draining soil, spacing plants 30-40cm apart. Position in full sun and water only when soil is dry to the touch; overwatering reduces leaf quality. Pinch out growing tips early to encourage bushy growth and delay flowering. For best production, plant in spring after frost risk passes in temperate zones, or in autumn in Mediterranean climates.
Sowing
Sow seeds 5mm deep in seed trays or directly in garden beds, spacing 30-40cm apart. Germination takes 7-14 days at 20-25°C. Direct sowing is preferred for this fast-growing herb; transplant only if starting early in cooler zones.
Care
Feed every 4-6 weeks during active growth with a balanced liquid fertiliser (e.g., 10-10-10). Prune regularly to remove flower buds and keep plants compact, which improves leaf quality. Remove self-sown seedlings to control spread.
Companion Planting
Plant epazote near beans and corn to benefit from its pest-repelling properties. Avoid planting with other strong-scented herbs like fennel or dill, as they may cross-pollinate. Isolate in pots to prevent self-seeding into garden beds.
Common Pests & Risks
Epazote is generally pest-free in Australian gardens. Occasional aphids on new growth can be washed off with water or treated with neem oil. No significant disease issues when grown in well-drained soil.
Harvesting
Harvest young leaves (4-6cm long) from 8 weeks after sowing, using them fresh or dried. Pick leaves before flowering for strongest flavour; remove flower stalks promptly to extend harvest. Use sparingly due to intense taste—a few leaves per dish is sufficient.
In the Kitchen
Use fresh epazote leaves in bean dishes (black beans, refried beans) for authentic Mexican flavour. Dried leaves are stronger—store in airtight containers. Add leaves at the end of cooking to preserve aroma; avoid boiling for long periods.
Troubleshooting
Yellow leaves: overwatering or poor drainage—reduce water and improve soil. Leggy growth: insufficient light—move to full sun. Bitter flavour: leaves too old or plant flowering—harvest young leaves before flowers appear. Stunted growth: cold temperatures—protect from frost or grow in warm zones. Leaf drop: sudden temperature change—acclimatise plants gradually.
