When to Prune Lavender in Seattle

In Seattle's mild climate (zone 8b), lavender pruning timing is crucial for flowers and plant health.

Best Time: Late Fall After First Frost

Prune in November or December, cutting back to about 3 inches above the woody base. This stimulates dense, vigorous spring growth and abundant summer blooms.

Why Not Spring?

Pruning in April removes the flower buds that formed last summer. You'll get few or no blooms this year, and the plant may become leggy.

If You Already Pruned in Spring

Accept a bloomless year. Keep the plant watered and fertilized lightly; it will recover for next season.

General Lavender Care for the Pacific Northwest

• Sun: 6+ hours direct sun.
• Soil: Fast-draining, gritty, alkaline (add lime if soil is acidic).
• Water: Deep but infrequent; let soil dry between waterings.
• Varieties: English lavender (L. angustifolia) like 'Munstead' or 'Hidcote' handles wet winters best.
