Leave the lavender alone
Avoid the temptation to cut back lavender plants this fall and winter in spite of their visual decline with the cold.
Lavender reacts badly to hard pruning and also may rot if given a thick layer of organic mulch in winter.
Wait for new growth to emerge in spring before trimming and tidying the plant.
Replace end-of-season annual container plantings with a display of winter heath and pansies or violas.
Make sure the pot is frost-proof (most clay pots are not) and free-draining. Freshen the soil with a potting mix.
Hard freezes in January will flatten unprotected pansies, but they will bounce back for a spring display.
