“Plants like carrots and even corn, they are really hard to transplant and they will germinate right into the soil anyway,” said Wendy Wilber, statewide Florida master gardener coordinator at the University of Florida. Some long-season seedlings can also be planted before the last frost.
How do you winterize carrots?

Why do farmers spray water before a freeze?
Cold weather prep for plants in winter
Drought-stressed plants are more susceptible to cold damage, so watering plants a few days in advance of a cold snap is beneficial. Watering just before the freeze can help too by creating warmth, and the water loses its heat slowly over the hours into the colder temperatures.
Can I cover plants with garbage bags for one night?
Yes – if you secure the plant properly. Garbage bags work to cover plants and protect from frost, but they must not be allowed to touch the plant’s surface. Use stakes and supports to create a tent-like structure over the plant, which will retain warm air. Make sure the trash bag goes all the way to the ground.
