Growing Mint in Zone 3B

Mint is incredibly vigorous and aromatic. Best grown in containers to prevent it from taking over your garden.

Zone 3B has a short growing season — start seeds indoors when possible and use season-extending techniques like cold frames and row covers.

Top Growing Tips

• ALWAYS grow in containers — mint spreads aggressively by runners
• Extremely easy to grow from cuttings — just root a stem in water
• Harvest frequently — pinching encourages bushier growth
• Many varieties: spearmint, peppermint, chocolate, apple, mojito
• Perennial in most zones — comes back stronger each year

Companion Planting

Good companions: cabbage, tomatoes (deters pests)

Avoid planting near: keep away from other herbs — it’ll crowd them out

Harvest Timeline

Harvest leaves anytime once established
