When to prune lavender

Prune lavender in early spring, once all chance of frost has passed and green leaves are emerging from the base of the plant.

The window: Early spring, after all chance of frost has passed (early March or so), when green leaves start to emerge from the base of the plant.

Wait until all chance of frost has passed before pruning.
Look for green leaves starting to emerge from the base of the plant in spring.
Wait for the green spring growth so you do not mistake live stems for winter die-back.

The mistake to avoid: Do not prune in July, because you will cut off the year's blooms-in-progress even if the plant has already bloomed twice in a season.

Timing varies by region and year; your local extension office is the closest authority.
