I live in zone 5, and wonder how I should treat Lavender before the
season starts....do I need to cut back last years growth? Thanks
Lavender hardiness depends on the species, but I am not aware of any
that will survive a winter in USDA zone 5 or even zones 6 and 7.
While pruning lavender will rejuvenate the plant, it must be done
carefully. As with other relatives of salvia -- rosemary, sage, mint,
etc -- there must be green leaves remaining below the cut. Otherwise
the branch will die back to its base. If a branch has no green leaves,
remove the entire branch. If there are no green leaves on the plant at
all, it is dead; lavender is evergreen.
