Update containers for winter color with cold-hardy kales, cabbages, and violets (Viola spp. and cvs., Zones 3–9). Incorporate evergreen cuttings and red- and yellow-twig dogwood stems (Cornus sericea, Zones 3–8) for added winter interest.
Weed winter germinating weeds. They are easier to remove before they get too large and go to seed.
Watch for interesting fall leaf and bark color on Japanese maples (Acer palmatum, Zones 5–9 and Acer japonicum, Zones 5–7) to help guide future selections.
Select and plant hellebores (Helleborus spp. and cvs., Zones 4–9) for fall and winter color.
