Saving FL Plants from Freezing

By: Skyepony, 5:03 AM GMT on December 30, 2007

The best thing you can do to ensure your plant doesn't freeze is bring it in a warm house. Those plants in little pots aren't looking too scared.

Is that veggie cold hardy??

Very hardy
broccoli, cabbage, lettuce, onions, peas, potatoes, spinach, turnip, microgreens

Hardy
beets, collard, kale, lettuce, mustard, beets, carrots, chard, mustard, radish, some tomato, winter squash like acorn, bell peppers

Not Cold-Hardy
tomato, squash, corn, beans (including Lima), some spinach, eggplant, okra, southern peas, sweet potato, cucumber, watermelon, zucchini & summer squashes, malabar spinach, sweet orange 2 tomato, yellow pear tomato, bananas, orchids, hot peppers

resource~ UFL


What if it's not cold hardy??

Water the ground well the morning before. Late afternoon to evening cover the plants with cloth or plastic sheets that go all the way to the ground. Much wind is expected, so plan to anchor sheets well. A light should be placed under a plastic sheet to give warmth & prevent plastic sheeting from freezing to the plant with the help of condensation. Cloth shouldn't freeze to plants without a light, but with high winds may not be enough. High wind & feezes are the worst so doubling a sheet covered by plastic, well anchored to the ground, with a light should be considered for anything of great value. one or several large potted plants can be carefully layed on their side, together, covered in a few layers, preferibly under an oak tree for added protection.

Growers style irrigation through a freeze is not recommended to by tried with your home sprinkler irrigation system as most aren't enough volume, killing plants & wasting water. Rinsing frost off your turfgrass isn't gonna keep it green either.

Citrus trees~ Limes & lemons seem to be least cold hardy. Many other types may be okay in 28-30ºF for a few hours, some lower. Denser, healthier trees should be more hardy in general. Also to be considered is your tree dormant or not. Trees not dormant will be hit worse by a freeze. To protect it~ lots of Christmas lights that make heat, then cover the whole thing in sheets.

Strawberrys & low to the ground plants can be protected with a light, deep mulch like hay.

Be sure to water any plants that need it in the morning. Including any frozen ground around a plant to thaw.

...FREEZE WATCH REMAINS IN EFFECT FROM LATE WEDNESDAY NIGHT
THROUGH THURSDAY MORNING...

THE COLDEST AIRMASS OF THE SEASON...AND POSSIBLY IN SEVERAL
YEARS...WILL BEGIN TO OVERSPREAD THE AREA TONIGHT. TEMPERATURES
TONIGHT WILL FALL INTO THE MID TO UPPER 30S...EXCEPT FOR LOWER TO
MID 40S ALONG THE COAST SOUTH OF VERO BEACH.

THE COLDEST TEMPERATURES ARE EXPECTED EARLY THURSDAY MORNING WITH
LOWS REACHING THE UPPER 20S ACROSS MUCH OF CENTRAL FLORIDA AND
SOME MID 20S ACROSS RURAL INLAND AREAS. A LONG DURATION OF SUB
FREEZING TEMPERATURES WILL BE POSSIBLE AWAY FROM THE COAST...WITH
TEMPERATURES REMAINING BELOW 32 DEGREES FOR AS LONG AS 8 HOURS
WEST OF I 95.

IT IS POSSIBLE THAT THE IMMEDIATE COAST...INCLUDING THE BARRIER
ISLANDS...MAY ESCAPE FREEZING TEMPERATURES WITH LOWS IN THE MID
30S.

Drought Forecast

By: Skyepony, 6:31 AM GMT on December 23, 2007

NOAA Updates U.S. Drought Forecast


“In spite of a number of winter storms that affected the nation during the first two weeks of December, much more rainfall is needed to bring wells, lakes, and reservoir levels back to normal in many areas of the Carolinas, Georgia, Alabama and parts of Florida,” said Douglas LeComte, NOAA’s Climate Prediction Center drought specialist. "Over the last year or two, the precipitation deficits in these areas have been measured in feet rather than inches”.
