Growing Lemon Balm in Zone 4A

Lemon balm is a vigorous, lemon-scented mint relative that’s impossible to kill — and equally hard to contain. Grow in a pot unless you want it everywhere.

Zone 4A has a short growing season — start seeds indoors when possible and use season-extending techniques like cold frames and row covers.

Top Growing Tips

• Grows in containers to prevent spreading; can take over garden beds
• Cut back hard after flowering to prevent self-seeding
• Fresh leaves make a calming, lemon-flavored tea
• Attracts bees strongly — excellent near fruiting plants
• Shade-tolerant; one of the few herbs that handles partial shade

Companion Planting

Good companions: tomatoes, squash, all vegetables (bee attractant)

Avoid planting near: No serious conflicts, but keep contained

Harvest Timeline

Harvest anytime; best before flowering for tea and culinary use
