What to Plant
Annuals/Bedding plants: Plants that can be added to the garden during the coolest months include begonia, browallia, lobelia, dianthus, dusty miller, and nicotiana.
Bulbs: Winter is a great time to plant bulbs that will bloom in the spring. Some examples include Clivia lily, crinum, and agapanthus.
Herbs: Many herbs will thrive now that temperatures are cooler, including tarragon, thyme, dill, fennel, and any of the mints.
Vegetables: Many vegetables can be planted this time of year. This is the last month to plant Irish potatoes, beets, broccoli, brussels sprouts, cabbage, cauliflower, collards, kale, mustard, and turnips.
What to Do
Landscape: It is a good time to plant woody shrubs. Water frequently to get new plantings off to a good start.
Irrigation: Water plants if temperatures remain higher than normal and rainfall is scarce.
Shrubs and trees: Prune non-spring flowering shrubs and trees this month to improve form.
Arbor Day: Celebrate Florida Arbor Day (the 3rd Friday of January) by planting a tree in your yard or community.
Crapemyrtle: Remove seed pods, crossing branches, and small twiggy growth to improve the plant’s appearance and form, if desired. Hard pruning is not required.
Cold protection: Bring sensitive plants like orchids inside if a frost or freeze is predicted. Thoroughly water and cover sensitive plants in the landscape 12–24 hours before a freeze.
Pests: Apply horticultural oil to citrus, shrubs, and deciduous fruit trees while plants are dormant to control scale. Apply copper spray to mangos after bloom.
