Gardening in December in Zone 7
By December, Zone 7 has passed its first fall frost (Mid October – mid November) and the outdoor season is largely over. It's time for cleanup, mulching, and putting beds to rest — though cold-hardy crops under cover can still produce.
There's little to sow now, but Kale, Spinach, Carrots, and Leeks should be coming ready in Zone 7 gardens — keep picking to get the most from each plant.
About December in the garden
December is the quietest month in cold-zone gardens. Planning, education, and equipment preparation fill the time. In warm zones, cool-season gardens are fully active and the holiday season includes fresh garden harvests. The winter solstice marks the turning point toward longer days.
