There are lots of fruit and vegetables ripening this month, so the most of the work will entail harvesting, drying, curing, and preserving for winter. If you're planting any winter crops make sure to plant in a site that is free-draining, sheltered from the oldest winter winds and in a position that will get max winter sun.
In warmer climates, continue sowing annual and perennial flowers, which may have started in mid-December. In coller climates, keep trimming back old rose heads to keep the plants in steady development. Keep lightly trimming lawns often. Don't cut them too short at this time of the year.
