Bring in clippings of winter greens such as juniper (Juniperus spp. and cvs., Zones 2–10), toyon (Heteromeles arbutifolia, Zones 7–10), and pine (Pinus spp. and cvs., Zones 2–9) to celebrate the season.
Plant out spring bulbs.
Start spring veggies—and consider edible flowers such as pot marigolds (Calendula officinalis, annual), borage (Borago officinalis, annual), and violets (Viola spp. and cvs., Zones 3–9), which bloom in winter and early spring.
Prune roses (Rosa spp. and cvs., Zones 3–9) and fruit trees.
