Central Florida Cold Snap: What did well and what did poorly?
« on: January 04, 2018, 02:58:33 PM »
In the northern part of Orlando, we hit 29-30F for about 4 hours early this morning. This is the first time that I offered no protection since I didn't think we would drop below 32F -- I was wrong. Most of the trees have about the same level of protection from the cold -- no micro climates on my property. I've surveyed the damage so far amongst the tropicals:

NO DAMAGE:

Michelia Alba -- no damage (surprised)
Large peach cobbler mango -- no damage
Mallika mango (small tree)  (no damage at all)
Jaboticaba -- no damage
Sapodilla -- no damage (all 5 varieties the same)
Day avocado -- no damage
Wurtz avocado -- no damage
white sapote (sue belle) -- looks great, no damage at all
tamarind -- no damage
Grumichama -- no damage
Barbados cherry -- no damage
Canistel -- no damage
achairu (achacha) -- no damage
pitangatube -- no damage
pitanga -- no damage
pitomba -- no damage
Australian beach cherry -- no damage
guava -- no damage
cherry of the rio grande -- no damage
feijoa -- no damage
lemon drop mangosteen -- no damage


SOME DAMAGE:

Lychees -- trees ok but new growth toasted (old leaves ok)
Kohala longan -- same as lychee (new leaf burn but established leaves ok)
Ylang Ylang -- most of the exterior leaves toasted; did much better than I thought
Small mangos -- both lemon zest (toasted leaves), Maha Chanok (leaf burn), Pickering (some burn); most burn on lemon zest.
Large mangos -- Carrie (some leaf burn)
Pakistan mulberry -- quite a bit of leaf burn
Gefner atemoya -- some leaf burn
figs -- toasted leaves 100% (all 20 varieties)
sugar apple -- leaf damage (not too bad surprisingly)
Wax jambu -- leaf burn
jack fruit (about 3 feet tall) -- some leaf burn; surprised it wasn't killed


QUITE A BIT OF DAMAGE:

Bananas -- toasted leaves and trunks (Manzano, Dwarf Cavendish, Ice cream, Golden)
Kary starfruit -- leaves toasted and crispy (tree will survive though)
Papaya (Red Lady) -- extensive toasted leaves
Muntingia (strawberry tree) -- leaf burn extensive
Pacay -- leaf burn extensive


EXTENSIVE DAMAGE:

Abiu -- toasted leaves and all dropped already (may not survive)
Rollinia -- toasted leaves and all dropped
Peanut butter tree -- all leaves toasted; looks bad
Dragon fruit -- don't think it will make it

How about you all?  Similar results or different?  I'm trying to narrow down what plants are really ok for 9b Central Florida -- without being next to a lake, etc.

I am south east of you almost to the Brevard county border. I anticipated low temps and got upper 20s and heavy frost and tonight will supposedly be colder than last night, but I probably wont have daylight time to go and survey damage to my stuff until Monday evening. But anticipating it I wrapped the trunks of my moringa and African sausage trees as well as a hong kong orchid(its not fruit but it looks nice). I covered all of my in ground mangoes, jackfruit, and wax jambu as well as mounded mulch around their bases. They should be ok like that until Sunday or Monday evening. Worried about my all spice and longon in the back yard and not too concerned about anything else, not like we got hit with an ice storm and the rain fortunately had plenty of time to dry before the cold hit yesterday.

We we're at 32 or lower for nearly 8 hours last night here in Lakeland. I'll only comment on things I didn't protect. We were at 28-29 degrees for about 4 hours of the 8. Indian jujube (Thai giant) looks toast this afternoon. Of course all bananas. Navel orange, pineapple orange, Meyer lemon, Ruby red grapefruit all look like they took a serious beating last night. I did not protect them because the freeze was far more severe than forcast. Starfruit leaves look to me like they had a bad night. All trees under cover with heat lamp are fine. Trees like mangoes all appear to be fine but I have heard they are slow to shown death signs. Some of these trees I protected with burn barrels and I suspect the side closest to barrel might be ok while opposite side will show damage within a week. All fig leaves were toast but expected. Mulberry leaves toast. Moringa toast. Peaches had no leaves as they were dormant. Everything in the garden took a beating. Guava tree leaves are looking worse and worse through the day. Dragon fruit cactus looks like it's turning to mush. I tried protecting the dragon fruit and guava as they were in proximity to a burn barrel but it failed to help. Tonight trees I protected like jackfruit, green sapote, macadamia nut, Sapodilla, sweetheart lychee, coconut cream mango are either going to have their plug pulled and left to the freeze as we are going to redo our entire project, or I may leave them plugged into the heat lamp and sell them as they are all small enough for transplant. My bacon and Mexicola avocado look good so far. Some leaf damage was spotted on my white sapote a few hours ago. Pineapples all took a beating accept maybe some that were close to burn barrels. I had freezing temps for two hours before I even got the barrels cranking as 32 degrees hit us 3-4 hours earlier than forcast.

Just did a walk around at 4pm. Longan leaves looking bad now, white sapote looks bad, both avocados especially the Bacon starting to show signs. Kent, Keitt, are both starting to show signs of burn. Glenn was better protected as I positioned the burn barrel better on that tree. Lychee showing some signs. We were hit hard here.

Lake Placid in Highlands county. We has a little frost about 2-3 weeks ago. Only some discoloration on my young sapodilla leaves. This morning however, my Raja Puri banana pup (3ft tall) looks like a goner. Young coconuts (1gal) not looking too good either. Fronds are brown-er. Seeing some frost damage on some of the lower mango tree leaves. Jackfruit trees not looking to bad neither. I didn't bother to venture too deep into my yard to fully assess the damage as I didnt want to lose too much sleep over it. After the next 2-3 more nights of this very cold weather then I'll fully assess. Brought in all of my seedlings and cold sensitive plants yesterday. Thank God I did. Mulberries did well.

Wanted to add that my two in ground peanut butter trees did well so far.  I have a pond on the front about 1/2 an acre. My neighbour to the left has a 1.5 acre pond in the back, and to the right, that neighbours has about 4 acres of wetlands.

Hit the low 40's here overnight. Did not bring anything in. All trees seem fine, including acai palm, jucara palm, borojoa, cacao, abiu, dragon fruit, etc. Might bring a few in tonight though, as it may get even cooler. Good luck everyone!

I managed a quick walk through before it got dark. We must have had a windstorm today, some of my deer cages I put blankets over went flying. My mountain annonna had fried leaves. My African Sausage every leaf was fried. Hope it comes back, trunk was wrapped in a heavy blanket though. Bananas ...... Everything else I looked at was ok. Now the cold night....

After night two. Apparently the wind turned my covered deer cage over my Wax Jambu into a kite and blew into the woods leaving it unprotected.
So heavily fried trees at this point:
Wax Jambu
Parts of wind exposed jack fruit
Mountain Annona
"gold" annona
Juman tree
Surinam cherry
melon berry
all gauvas except lemon guava which doesnt appear to have noticed it was cold
Pommalo
sugar apple even though it was in the process of dropping its leaves anyway
White Sapote
Black Sapote
a lot of my ornamentals turned straight up brown.

Frost damage is not immediately seen, most severe symptoms start showing up after days and sometimes weeks, that has been my observation from last two Frost's in southern California few years ago.

True ^ Damage not always evident right away. Also some species are fine with a quick cold snap one morning, some aren't, and some are more affected when it's multiple nights/mornings in a row like this front.

Did a walk through the property today. My mango trees are young and new planted from 3gal to 25gal. Some burn was evident. Julie, East Indian, Ice Cream has some bad burn but still green stems.  ZIC's 5inch inflorence are droopy so potential crop loss there. 1gal Coconuts took a hit. Crispy brown but the cores are still green so we'll see. The bananas will survive. Jabo looked normal. Grumichama, Jamacian Cherry, Pitomba.....normal. The next few days will reveal the true damage. Thinking about tall hedges and multiple burn bins.

I decided not to stress this cold snap, and just did c9 xmas lights and not full shelters. My low was around 30 going off the nearest weather station's readings. Some bananas (unprotected) browned, and unfurling leaf tips on my lychee got nipped back a bit, but all else looks good. The lychee should be about perfect, it nipped back flushing leaves, so hopefully it will rebound with flushing blooms instead=)

An interesting observation - the area of my yard that is coldest, where the bananas browned, the tri-colored oyster plant next to them were totally melted. In other areas of my yard that get less cold due to microclimates, the oyster plants are undamaged, and so were bananas in those spots. Since they are a really common landscaping plant, the oyster plants seem to be a nice indicator for people contemplating zone pushing. If the oyster plants get killed back by frost in your neighborhood, chances are any mangos, lychees, bananas etc you are contemplating adding will need cold protection.

Wow I finally got a chance to walk around and look at things. I have some odd micro-climates apparently.
My eastern grove with its 35ish trees is toasted. I even put some up under the oaks that are in the woods on the east side of my property. They always have sun but are somewhat protected. I thought. Pretty much every tree that hadnt already lost its leaves is a brown color now. Mangoes protected by sheets, jack fruit protected by a thermal blanket, deer cages wrapped in blankets, most sensitive trees mulch mounded up their trunks. The only trees that are evergreen that are still green are my carob and Irish strawberry. The strawberry is no surprise since I got it from Washington state. Fried from this area consist of 2 mangoes, a jackfruit, jamun, a few sugar apple types, moringa, spanish lime, reb jaboticaba, a rainbow eucalyptus, a bunch of guavas, and some other odds and ends.

Now my back two grove areas had the opposite happen for the most part. This area is also partially shaded by oaks on the north side of my property. My all-spice trees and fully exposed longon took it like champs and have very little visible damage. All of my lychees look fine except for the biggest one that had some fresh leaf flush that burnt and not even all of that. Now next to my longon a black sapote took it hard and a mulberry nearby has a lot of burned individual leaves. Dragonfruit so far dont seem to care.

My fruit orchard looks horrible. Two mangoes which were covered with thermal blankets and mounded are sickly yellow brown, although the cotton candy being bushier seems to have some green leaves in the center. Most of my ornamentals are brown/black but I expect them to come back in spring. Black pepper climbing my oak? Gone. A lot of bromiliads under that oak are yellow now. Mountain annona, starfruit, white guava, melon berry, my prized African sausage, favorite productive sugar apple and another jackfruit, all in varying shades of brown/black. The Mountain annona is supposed to not care about high 20s. A cheriyoma looks in rough shape but hasnt changed yet. A white sapote has yellowed but not turned brown either. Bananas of course are toasted, hope they come back.

Things that weathered the storm well, olives show no concern, lychees, loquats, pomegranates, lemon guava out in the open, pineapple guava, citrus(even a Key Lime in the open with no protection), Irish strawberries, carob, Allspice(could be from a protected microclimate).

Now to see what comes back and that will determine what I need in the future to replace things with.

For those with serious mango damage. 
I had a mango I took for dead many years ago.  It had been unprotected and the temperatures had dropped and stayed low for a long time.
All the leaves fell off and I was sure it was dead.
I cut off the upper part leaving about a two foot stump that I planned to dig up when I had the time.
You can only imagine my surprise when the plant came back.  Pushed new shoot all over and today it is a very happy tree. 

What I am saying is, unless the replacement is ready consider cutting back trees that may look like they died.  If they did, it wouldn't matter and you will remove them anyway when you replacements are ready.  If they are not dead you could be rewarded with your nice trees back producing in a year instead of starting a new tree and waiting a couple of years.

I was looking at your list.  We are in Houston which was zone 9, but someone changed the zone to 8.
We just experienced a hard freeze 20 degrees with ice/sleet.  We spent the entire day from morning
til dark covering fruit trees.
The main tree I wanted to comment on was the Cherry of the Rio Grande.  Ours is about 5 years old.
This tree took the temperature with no damage.  Even a baby Rio I planted is coming back out.
We covered the Kari Starfruit, but we always cover this tropical tree.  We also had Christmas lights on
lots of trees. 
This is the second Barbados Cherry I have lost.  If I get another, I'll leave it in a pot.  We definitely know what will
make it and what will not.  We have dug up the persian lime, a lemon, and one other that will seem to
never be able to fruit.
The older Jacotabica has lost all its leaves, but is still green on the stem.  The cara cara orange faired the worst
of all the citrus. 
I am going to post here hoping someone many know help for the newly planted Joey avocado. 

Hope this never happens to you or I again.
Wishing you well with your trees.  Carol in Houston

Several weeks later, damage is still pretty bad.
Jackfruit, despite being covered fried and the branches snap fairly easy. I think they are toast.
Mangoes are still iffy.
Sweet tart while losing all of its leaves and branches snap fairly easy, has new growth coming out from the trunk.
Lemon Zest rubbing the bark shows green so I think it will come back.
Cotton Candy lost the upper 2/3rds but bottom third has green leaves.
Graham lost all leaves and I haven't rubbed bark to see if its green under.

Barbados cherry no sign of life
Sugar Apples(all types) no signs of life. (not unexpected since they normally lose leaves for winter anyway)
Melon Berry, raison tree, che, ice cream bean, java plum, moringa, pintanga, pitangatuba, all gauavas except Lemon(no damage at all), African Sausage, carambola, mountain annonna, black sapote, no signs of life

Other trees that lost all leaves but have new shoots:
Jamun, white sapote, wax jambu, all Jaboticabas,

Nam Doc Mai #4 I gave to a friend in Ocoee almost died.  Hope something lives above graft on wrist thick trunk.

Coconut cream and fruit punch took the worst over in Titusville where they had a mid day ice storm. One of Lisa’s neighbors used to have a fruit punch but it’s a goner and Lisa’s is pretty close.

In my yard surrounded by young mango trees with burnt leaves the juicy peach looks amazingly well.

Not a single leaf damaged.   I have been impressed with the tree so far which has grown the most of my new planting’s and now it looks to be a touch more cold hardy...

A month post freeze I would say for me things are much better than I originally expected. I lost two mango seedling trees which were 3-5' tall. It appears I lost my Thai giant Jujube (indian). Starfruit had defoliated completely and I pruned them back and they are putting out new growth everywhere. My main mango trees are flushing and flowering right now, they were protected using burn barrels. Pretty much everything is flushing or flowering on my project right now. Working on some overhead irrigation for freeze protection in some areas of my project. So long as we don't get hit in March I'm much happier than I was originally after the early January freeze. It took a lot of work to protect this much stuff but things will survive another year.

Here's my update on apres freeze garden.

Lost:  9 seedling mango (4x atulfo, 5x store boughts), 1 seedling duncan grapefruit, 6x papaya, numerous mid-size bananas and about 10lbs of sweat for moving all my potted plants indoors and then out again.

Key Lime - lost 95% of its leaves and had a bunch of branch die back.  I pruned the deadwood and it started flushing new growth about 10 days ago.  Was in ground for about 1.5 years and bought at HD.



Meyer Lemon - lost all its leaves but 1 and also had a bunch of branch die back.  Deadwood pruned back but no flush yet.  Was in the ground for about 1.5 years and bought at HD.



Duncan grapefruit seedling.  This little guy was just about 1 year old when the freeze hit and had been in the ground about 7 months.  It was 18 inches before the freeze and now its down to about 4.5 or 5 inches.  After trimming the deadwood off the top 10 days ago it has also started flushing nicely.



Haas seedling avocado.  This one's a bit interesting.  I planted 3 avocado seeds into the same hole last august but only 1 of them sprouted.  It got to about 12 inches tall before the freeze and ended up freezing all the way to the stems.  It bounced back nicely, but here's the surprise.  One of the other pits I put in the ground that never sprouted last year sprouted now !!  It's the one on the left.  Wasn't expecting that.



Florida prince peach.  Just starting to push out some growth.  Should be no issues with this one.



Bananas were hammered.  I've kept cutting back all the dead/decaying tissue and have a stump or two pushing out growth.  Still holding off hope for some nanners this year but not sure.  Great new growth on the bottom of them all though.



Pineapple patch was where I put the most effort into saving as it is close to our house and has a southern face so it warms up earlier in the day.  I put paint drop cloth over the pineappples and ran an electric heater about 7 nights this year.  They seem to be fine except that one that is starting to yellow up a bit.  All pineapples are dole twist-tops from the store that I just stuck into the ground and they rooted.

Hi Carol
I am in New Orleans... Very similar here.
it hit 20F... 50yr, maybe 100 yr record low.
i had the same experience.
my CORG had no damage at all.
4yr old starfruit looks like it might not come back
(although i read somewhere about one coming back from the low 20s)
i had lots of damage to the Jabos, but they are alive.
grumichama, green sapote, jackfruit, bloack sapote
all look dead.
last year i had several plants i thought i lost, but a few started sprouting from the roots
some in April, some May, some not until June.
i hadnt heard of one taking over a year, but its good to know.
i have 2 mango in ground that had gotten farily large,
 i have to think the root system didnt freeze too badly.

i had put 5gallon buckets of hot water, and covered several small trees with blankets/sheets, etc...
i am crossing fingers on the baobob and inga... they were pretty large
and if the roots didnt freeze for too many hours they might come back.
