Seed Depth: Surface sow, press lightly into soil

Seed Spacing: 12–18 inches

Row Spacing: 18–24 inches

Sunlight: Full sun to partial shade

Days to Sprout: 7–14 days

Days to Maturity: 60–90 days

Growth Habit: Spreading perennial

Sunlight: Thrives in full sun but tolerates partial shade, especially in hot climates.

Soil Type: Prefers moist, well-drained soil with a pH of 6.0–7.0. Adding compost improves fertility and moisture retention.

When to Plant: Start seeds indoors 6–8 weeks before the last frost or sow directly outdoors after the danger of frost has passed.

Direct Sowing: Sprinkle seeds on the soil surface and press lightly. Spearmint seeds need light to germinate.

Indoor Sowing: Surface sow seeds in seed trays and keep moist. Transplant seedlings when they are 2–4 inches tall.

Succession Planting: Not typically needed; spearmint is a vigorous perennial that regrows each year.

Watering: Keep soil consistently moist but not waterlogged. Spearmint prefers damp conditions.

Fertilizing: Apply a light layer of compost or a balanced fertilizer in spring to encourage new growth. Avoid excessive fertilization to prevent loss of flavor.

Pruning: Trim plants regularly to promote bushy growth and prevent spreading beyond desired areas.

Pest and Disease Control: Generally pest-resistant but monitor for aphids and rust. Maintain good airflow to reduce the risk of fungal diseases.

When to Harvest: Harvest leaves once plants are established and at least 6 inches tall, typically 60–90 days after planting.

How to Harvest: Snip sprigs with scissors or gently strip leaves from stems. For the best flavor, harvest in the morning before the sun intensifies.

Seed Collection: Allow flowers to dry on the plant and collect seeds from spent blooms.

Storing Seeds: Store seeds in an airtight container in a cool, dry place.
