In the fall, after the second flush has come and gone, prune the stems down to an inch above the wood. Leaving them long will create space for snow to collect on the shrub and break it, or wind to blow off weaker branches. Pruning the shrub to prep for winter will make it much more likely to survive the harsh weather. Taking the time to do this will also help to prevent more of the shrub from turning to wood. The parts of the plant that turn to wood won't produce new lavender stalks; the stalks grow from new shoots that emerge from the shrub every year. A big, woody base is prone to cracking or rotting, so the idea is to keep it from getting too woody. Even though you don't want the base to get too woody, you can't cut away old wood on a lavender shrub. Some shrubs rejuvenate themselves when you cut back the wood, but lavender doesn't. What you cut won't grow back. Make sure you never cut the part of the shrub that has turned to wood. If you live in a place with heavy snows and harsh weather, your lavender bush is likely to lose a few branches over the winter. Examine the shrub in early spring, before it begins producing new shoots. Remove any broken or rotting branches to make way for new growth.
