Here is what I have outdoors unprotected unless severe freeze. In in Pensacola not far from your destination. Id advise to locate as close to the coast as possile for the additional heat.

Blood Oranges, - excellent
Hamlin oranges - have been better producers and are cold hardier- Trifoliate and us 897. - no production from us 897 yet
Myers lemon- softball lemons - trifoliate rstk
Owari Satsuma- think it was cleopatra rootstock
Ponkan Mandarin-- unknow rtstk
Xie Shan -
Navel orange- excellent - trifoliate
Dekopon- plant is hardier than fruit it appears . fruit is excellent but cold intolerant below 32

others that friends grow-

kimbrough satsuma, ichan lemons for sure.

Not citrus but here are some others

apples- anna dorset golden and ein shimer
look into thornless arkansaw self erect black berries exceelnt - apache navaho arapahoe for all summer long production
kiwis- friends grow them prolific thouh needs few years and trellis system


plums-
santa rosa , methley, catilina, burbank. I have specific recommendations for rtstk for these. Let me know if interested.

blueberries-- titan, vernon and --SUNSHINE BLUE- the best in my opinion because most toletant of high ph of all the verieghties Ive grown. 5-1-1 mix in pots for these - You have tons of blueberries !-- I use 55 gallon water barrels (plastic) and cut in half for each plant. I like to move mine around..


And many more I could list that Ive got growing. This should start you off.

When do the Blood Clemintines ripen? Also are these the same as Mandared Mandarins, Red Nules?

The fruit on mine are 90 percent orange with just the neck and areas in fruit in the interior that are still showing slight green tint. The fruit is noticable sweeter. im pulling one every  wek or so  now though January.

If temps are under 90F when you apply and 24 hours thereafter, a mix of dormant oil and malathion is the ticket.  Just got rid of soft scale on a blood orange.  Wouldn't have notice it if I hadn't seen the soot.

Also, keep control of ants.

Second this. 
Has for me. Saw Marks post and responded as Ive used same mix and it worked. Only used it a couple times on soft scale and it stopped them. I use it every year on  black scale on Olive trees and it works for them as well, but these need to be scraped first as the malathion spray only kills the young ones before the shell hardens. Be carefull though on young trees without canopy shade protection as oil can burn as bsbullie referenced. Ive never had that issue though as I try to spot treat  areas not the whole tree. Like to hear what Marks opinon is. He may have more soft scale issues .

For hard scale- credit card scrape (pia) then malathion sprayed two feet in either non infested direction. Reapply after rain as it will wash off. 
Also circle trunk at base to stop ants.  After several applications no further hard scale.

Does it work against the soft scales too?

Thats not right...sigh... Wish I could take you up on that... looks really good and sweet!

Welcome back...Blood clementine...how do those taste? never seen one.

In about 5 years.

After growing citrus in ground in freeing zones for years, I have to say that Grapefruit is highly cold tolerant.  Never even got leaf burn from 15°F where even the kumquats and calamondins suffered a little.  Oranges definitely do not have them beat, and my satsumas dropped leaves and suffer branch die back at 20°F.

Here in 8b/9a oranges left to their own will all perish unless protected until larger- then every fourth or fifth year they too may sucumb to  a 18-22 degree hard freeze. Grapefruit on the other hand grow wild here... I believe grapefruit trees themselves survive due to the much larger mass of the trunk/tree. Neighbors tree is 30 feet tall and look like a...tree. Much larger than other citrus in general.

Also ...leaf temp is more important than outside ambient air temp. Too many worry about air temp. Im more worried about the conditions that are occuring with the cold.  When there is no wind and I can see the stars on a clear cold night- danger,danger.  This is more dangerous because air temp may be say..29 outside for 4 hours but the leaf/trunk through super cooling(radiative cooling) can be 2-3 degrees cooler and sub 29 for 6 hours. 

On the other hand- when it is windy and the air is moving I rely more on the actual weathermans forcast low temp as the wind keeps the citrus the same temp as the air.

Anyone know where I can find one here in Florida to buy online?

Is your heater the type that does not put out ethylene gas as it burns?

A quick research found that this gas can be controlled by 1 square inch of vent per 2000 btu of heat via propane. In citrus it actually hasten ripening as Ive just read  that ethylene is used to color up citrus. Ill vent the greenhouse with slightly adjar intake and exhaust louvers to make sure though.

 Im also only going to heat for a few hours on low setting just enough to keep the greenhouse at 38 or so instead of the original plan to maintain 45 to 50 degrees with an all night full burn setting... too much experiments to be done still as the greenhouse is on its trial run.

Any info on this ethylene  issue would be appreciated.

I think the same. Seems that and extended store in the refrigerator would dry the fruit out. Im going to place about 5 in freezer bags in the bottom drawer of the fridge to see how they taste after a month or so.

I picked another one last night and the fruit was not as good. About a quarter of the segments on one side seemed dried out. The rest of the Dekopon was juicy with noticeably less acidic bite . I wouldnt say sweeter but less acidic then the one I tried earlier. Thurs and Friday are  predicted to be 35 and 32 degrees lows with Friday holding 32 for 6 hours or so. Im going to close the greenhouse up and heat with a propane heater.



 I tried it out a few nights ago and  raised the temp from 58 to 70 after about an hour or so at full setting (25k btu) in the green house. Im not sure what it will do at 32 outside. Ive ordered a second one in case it cant hold a 10 degree differential from the outside air. 

Glazed terra cotta pots slow transpiration and seem to work better for me. Less prone to chipping and cracking as well.
