Ed Lizard Posted December 13, 2010 Share Posted December 13, 2010 May be time to switch to Texas Ruby Red Grapefruit. Closer to home, I watered the heck out of my orange tree last night. 4ºF disparity between IAH and DWH. 26º at DWH, which probably did kill the tree if it happened in my back yard. But you live in Texas, in the mid-latitudes, four distinct seasons, 3 snowstorms in the last 6 years, you take your chances. Kills me that one of my oranges died last year when several neighbors with Manila Palms, completely unsuited for our brutal winters, had their trees survive. Anyway, if not Texas grapefruit, they grow oranges in California and Brazil... AREA FORECAST DISCUSSIONNATIONAL WEATHER SERVICE MELBOURNE FL 345 PM EST MON DEC 13 2010 ...DAMAGING HARD FREEZE THE NEXT TWO NIGHTS... ...DANGEROUSLY COLD WIND CHILLS TONIGHT... .DISCUSSION...

Ellinwood Posted December 13, 2010 Share Posted December 13, 2010 Advective freeze vs. radiational cooling freeze; I would be more concerned tomorrow night... True that... actual lows and wind chills will be a bigger effect on the population tonight, but the big concern over the vegetation will be the continuing (albeit very slightly less) cold when frost could actually form tomorrow night.

Wouldn't the traditional citrus protection methods, sprinklers, to form an ice barrier, or smudge pots work better in light wind? Link to comment Share on other sites More sharing options...

The frost will have a really, REALLY tough time forming with the wind blowing and the dewpoints dropping, though. You could be right... I'm not well-versed in Florida's agricultural habits.

Guest someguy Posted December 13, 2010 Share Posted December 13, 2010 Yes have been telling my ag folks since friday that the winds might stay up that of course would reduce a FROST... but NOT a freeze which can occur without a frost. in other words 28 degrees for 3 or 4 hrs with a n winds art 7 or 9 MPH ....NO major frost below 25 degrees for 6+ htrrs with a nw winds at 7 or 9 MPH sure you have NO frost But that Orange is now a fooking baseball Link to comment Share on other sites More sharing options...

But at those temps, it doesn't matter, they totally freeze and it's a moot point. Link to comment Share on other sites More sharing options...
Srain Posted December 14, 2010 Share Posted December 14, 2010 Meh. 39 from Leesburg to Winter Haven at this hour. Much to do about nothing regarding the 'crop' tonight. Link to comment Share on other sites More sharing options...

So you didn't but FCOJ futures? 26F at DW Hooks, about as close to my house as IAH. Did my orange tree survive? Haven't had the courage to check. BTW, 26 at Hooks and just a glancing blow for Texas. If the people at NWS MLB are talking lower to mid 20s, I'm not ready to dismiss them. Link to comment Share on other sites More sharing options...
Calderon Posted December 14, 2010 Share Posted December 14, 2010 This is the third year in a row with a freeze in southern Florida. which is really starting to eat into the palm and plant nurseries, especially after last winter where palms had damage on Miami Beach.
