How to Grow Mints: The Complete Guide

Mint (Mentha spp.) is a easy-to-grow cool to warm-season herb that thrives in USDA zones 3-11. With the right soil, sunlight, and care, you can harvest fresh mint in as little as 30+ days. This guide covers everything you need to know about growing mint at home—from planting to harvest.

Overview

Mint is one of the most vigorous and forgiving herbs, producing fragrant leaves for teas, cocktails, salads, and desserts. Its enthusiasm for spreading is legendary, so container growing is strongly recommended.

When and How to Plant Mints

Start indoors: 8-10 weeks before last frost. Mint needs partial to full sun and rich, moist, ph 6.0-7.0 to thrive. Plant seeds at Surface sow depth with 18-24 in between plants.

• Sowing depth: Surface sow
• Plant spacing: 18-24 in
• Germination time: 10-15 days
• Days to harvest: 30+ days
• Best soil: Rich, moist, pH 6.0-7.0
• Season: Cool to Warm season — zones 3-11

Care and Maintenance

Mint requires regular to moist watering and partial to full sun. Consistent moisture is especially important during the growing season when roots are establishing.

• Watering: Regular to Moist — water deeply at the base, not overhead, to prevent leaf disease
• Mulching: Apply 2-3 inches of straw or shredded leaves to conserve moisture and suppress weeds
• Feeding: Apply balanced organic fertilizer or compost tea every 3-4 weeks during active growth
• Watch for deficiencies: Yellow leaves = nitrogen, purple stems = phosphorus, brown leaf edges = potassium

Pro Tips

ALWAYS grow mint in containers—it spreads aggressively by underground runners and will take over garden beds. Even in the ground, use buried barriers.
