Answer: The time to prune lavender is in early spring once you are able to tell which parts have winterkilled and which parts are still fully alive. You would trim off any winter damaged stems, and then cut the rest of the plant back to restore a fairly symmetrical look and remove about half of the overall size. Since it is getting ready to bloom, you could trim off just the dead portions now. After the blooms fade, then give the plants a light shearing to deadhead and tidy them up. Next year, prune in early spring.
