Wondering what to do with your lavender plants in the Fall?
I may give my lavender a very light trim in August but other than that I leave it alone until Spring. Although some varieties are cold hardy for Zone 5, they can still struggle from a harsh winter. Leaving them unpruned will give them more winter protection.
When Spring arrives you can trim them back but make sure you never trim back into the wood of the stem. They will not produce new growth if you do this.
Not pruning your lavender will have it become woody and leggy. It will also begin to bloom less and less over time.
