Growing Lemon Balm in Zone 3B

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 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
