Growing Lavender in Zone 4B

Lavender is a fragrant, drought-tolerant herb that attracts pollinators and looks beautiful in any garden.

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

Top Growing Tips

• Must have excellent drainage — raised beds or sandy soil work best
• English lavender is hardiest (zones 5-8); French/Spanish need zones 7+
• Don’t over-mulch or overwater — mimics its native Mediterranean conditions
• Prune after flowering to maintain shape and prevent woody centers
• Harvest when about half the flowers on the spike have opened

Companion Planting

Good companions: roses, echinacea, yarrow

Avoid planting near: shade-loving or moisture-loving plants
