January in Florida is what June is to the rest of the country. Everything cool-season is either producing at full tilt or ready for one more succession planting. If you timed your fall planting right, your garden should be delivering right now. Missed the fall window? You still have time to get lettuce, peas, radishes, and herbs in the ground.

This is the seventh installment of our Florida Growing Calendar series, and it marks the start of our second year at Wholly Water Farms. We started in January 2024. One year in, our grow racks are fuller, our customer list is longer, and every lesson from year one is shaping year two.

Why Is January the Best Month for Cool-Season Growing in Florida?

January gives Florida growers the cool, stable conditions that most vegetables prefer. Average daytime highs across Central Florida run 68-72°F, with nighttime lows of 45-55°F. These temperatures are textbook for lettuce, brassicas, root crops, peas, and cool-season herbs. Soil temperatures in the 55-65°F range keep germination steady without triggering the premature bolting that ruins late-season plantings in March and April.

Rainfall is also low in January — typically under two inches across most of the state. That means you control the water, which is exactly what cool-season crops need. Overwatering causes more problems than underwatering for winter vegetables in Florida's sandy soils.

How Should You Succession Plant Lettuce in January?

Succession planting is the single most effective technique for continuous lettuce. Plant a new batch every two weeks so that as one planting hits harvest, the next is coming up behind it.

In January, direct-seed loose-leaf varieties like Red Sails, Black Seeded Simpson, or Salad Bowl every 14 days. These varieties reach first harvest in 28-35 days from seed, so a January 1 sowing gives you greens by early February. A January 15 sowing extends that through late February. One more sowing in early February pushes you into March — right up to the edge of when lettuce starts to struggle with rising temperatures.

For head-forming varieties like Romaine or Buttercrunch, use transplants set 10-12 inches apart. Romaine takes 55-70 days from transplant to mature heads, but you can harvest outer leaves starting at 30 days.

What Do You Do with Broccoli After the Main Head Is Harvested?

If you planted broccoli transplants in October or November, your main heads should be ready by now — or already harvested. But do not pull those plants. After you cut the central head, broccoli produces side shoots from the leaf axils that continue for six to eight weeks. These side shoots are smaller (two to four inches across) but just as flavorful and nutritious as the main head. Some growers actually prefer them because they are more tender.

Keep feeding the plants with a balanced fertilizer after harvesting the main head. Water consistently. The side shoots will keep coming as long as nighttime temperatures stay above 35°F and daytime highs remain below 80°F. In Central Florida, that window usually extends through mid-March. Green Magic, Destiny, and Waltham 29 are all reliable side-shoot producers.

What Is the UF Sensation Strawberry Variety?

The University of Florida's strawberry breeding program dominates Florida's $400 million strawberry industry. The variety getting attention now is Sensation (officially UF Sweet Sensation, released in 2020), bred for our climate. It requires only 150-200 chill hours and produces large, conical berries with brix levels consistently hitting 8-10 percent — noticeably sweeter than older commercial varieties.

January is prime strawberry season. If your transplants went in during October or November, they should be producing now. Keep beds mulched, remove runners so the plant's energy goes to fruit, and use drip irrigation at the crown level. Overhead moisture causes Botrytis fruit rot — the biggest disease concern during cool, damp Florida winter mornings.

Which Herbs Perform Best in a Florida January?

January is peak herb season in Florida, and three cool-season herbs are at their absolute best right now: cilantro, parsley, and dill. These are Mediterranean and cool-climate herbs that bolt quickly once temperatures climb above 75-80°F, so enjoy them while you can.

Cilantro should be succession-planted every two to three weeks. The variety Slow Bolt gives you an extra week before flowering, but nothing stops cilantro from bolting once the heat arrives. Harvest outer stems, leaving the center to keep producing.

Parsley — both Italian flat-leaf and curly — is slow to germinate (14-21 days) but once established, produces steadily through April. Harvest by cutting outer stems at the base, never topping the plant.

Dill grows fast and goes to seed fast. Sow thickly and harvest the fronds young. Bouquet and Fernleaf are the best Florida varieties. Dill self-seeds readily, so let a few plants flower for volunteer seedlings.

Can You Still Plant Sugar Snap Peas in January?

Yes, and January is actually the ideal time for a second succession planting if you put your first round in during November. Sugar snap peas like Sugar Ann (bush type, 56 days) and Super Sugar Snap (climbing, 64 days) thrive in January's cool temperatures. Direct seed one inch deep, two inches apart, along a trellis or fence. Climbing varieties need at least five to six feet of vertical support — they will keep climbing as long as there is something to grab.

Inoculate seeds with a Rhizobium legume inoculant before planting — this soil bacterium colonizes pea roots and fixes atmospheric nitrogen, reducing fertilizer needs and improving soil health. A $5 packet treats enough seed for 50 feet of row.

What Root Vegetables Should You Plant in Florida in January?

Carrots, beets, and radishes are all still plantable in January across Central and South Florida. North Florida growers are pushing the edge of their window but can squeeze in a late planting with row cover protection.

Crop	Variety	Days to Harvest	January Planting Notes
Carrots	Nantes, Chantenay, Danvers	65–80	Direct seed; thin to 2 inches apart; sandy soil ideal
Beets	Detroit Dark Red, Chioggia, Golden	50–60	Direct seed; soak seeds 2 hours before planting; harvest greens early
Radishes	Cherry Belle, French Breakfast, Watermelon	25–35	Fastest root crop; succession plant every 10 days
Turnips	Purple Top White Globe, Tokyo	40–55	Harvest young for best flavor; greens are edible and nutritious

How Do You Protect Plants from a Florida Freeze?

Florida freezes are not frequent, but they happen — the January 2024 freeze dropped below 28°F across parts of North and Central Florida. Vegetable gardens are vulnerable, especially transplants and tender herbs. Here is what works:

Row covers (frost cloth): Lightweight (1.5 oz/sq yd) floating row cover provides 4-8°F of frost protection. Drape over hoops so it does not rest directly on foliage.
Mulch: A three-inch layer of straw or pine needles insulates the root zone, keeping plants alive even if top growth gets frost-burned.
Water before the freeze: Irrigate thoroughly the afternoon before a predicted freeze. Moist soil radiates more heat, raising ground-level temperature by 2-4°F.
Containers: Move potted herbs and greens into the garage or house for the night.

At Wholly Water Farms, our indoor growing systems make freeze worries irrelevant. Our microgreens and hydroponic crops grow in a climate-controlled environment regardless of what is happening outside. That is one of the underappreciated advantages of controlled-environment agriculture — no weather risk.

Frequently Asked Questions

Is it too late to plant vegetables in Florida in January?

No. January is still well within the cool-season planting window for most of Florida. Lettuce, radishes, carrots, beets, sugar snap peas, cilantro, dill, and parsley can all be direct-seeded this month. Broccoli and cauliflower transplants are best started no later than early January in Central Florida, while South Florida growers have until late January.

How often should you plant lettuce for continuous harvest?

Plant a new batch every two weeks throughout the cool season. This staggered approach means that as one planting reaches harvest maturity, the next is coming up behind it. Loose-leaf varieties reach first harvest in 28-35 days from seed, so biweekly sowing keeps your supply unbroken from November through March.

What temperature kills strawberry plants in Florida?

Strawberry flowers and developing fruit are damaged at temperatures below 28°F, though the plant itself can survive brief dips to 20°F. Use row cover or frost cloth on freeze nights to protect blooms and developing berries. Established strawberry crowns are surprisingly cold-hardy, but the fruit set is what you lose when temperatures drop below freezing.

Do broccoli plants produce more than one head?

Yes. After you harvest the main central head, broccoli plants produce smaller side shoots from the leaf axils for six to eight weeks. These side shoots are two to four inches across, tender, and just as nutritious as the main head. Keep feeding and watering the plant after the main harvest to maximize side shoot production through March.
