Wow! Night time temps dropping to the 30s! Luckily my bananas are in pots but the leaves are definitely suffering. Out of the three - Cardaba, Miki Luki and FHIA-18 - Cardaba is doing well.

How come I don't feel it here when I am only 43 miles from you? At least my bananas are still green this morning.

Its been in the high 30s here at night here in houston. just as a precaution I went ahead just mulched the nanners with some hay I had around.

I am not doing anything so far. I am waiting when the tempt drops at zero

NE of Sacramento, we have been lucky so far, no frost or freezes. (I've been worried though)

Everything looks good except normal spotting from cold temps. M. Kru though.. doesn't look too good. I think it doesn't like temps under 40?

Things are doing ok here in Fresno. They say maybe rain this after noon. It should hit Sacramento first than come my way. Its been cold in the mornings and than nice in the afternoon.

It's cold here but not enough to affect my bananas. I am the lazy type though I wait until it hits and then I do something.

Wow, that's pretty cold guys! It's been in the low 40's high 30's here at night. You think you'll have a record cold winter for you guys out there?

32 degrees or lower is all you need to worry about.

Not that it will do you any good to worry about it!

Up here in East Palo Alto its only reached ~38.5F, I'm hoping all of the extra moisture we are supposed to get keeps the winter warm.

'They' said we here in SE Louisiana are to have a mild to warm and wet winter. But that's just an average. That doesn't mean it won't get cold. It will still get below freezing possibly 3 to 5 times in some places, maybe 2 to 3 times in others, and possibly 0 times in some. What 'they' say because of el nino/la nina/la nada does does not translate as solid. Just as the term global warming does not exactly mean the planet is warming up. It's a stupid term that is abused and misused and not true. This whole emissions thing has all of the sudden been turned into trade and cap for carbon footprint? WHAT? That's the dumbest thing I've heard in a long time. It doesn't STOP it!

But hey, everything has to have a name or definition now. Before it was, Oh I've got a slight cold. Now it's called S9-KO87 or something.

Point is, don't trust 'them', trust what your area normally does. Exclude the nino and nadas because, as far as a freeze goes, they mean nothing.

We've had frosts three mornings south of Sacramento (Delta) this week, with yesterday being the hardest, reaching a low of 32F. Leaves look okay so far...I've got fruit hanging on one tall unknown plant again late this year so I am spraying it with water and used a smudge pot a couple of nights as I want the fruit to size up more.

Benny, you are waiting until zero?? I assume you mean Oc, I hope!

Tommy, even without reaching 32F we can have heavy frosts which will kill back the leaves. That doesn't kill the plant, but that will certainly stop my fruit from sizing up. I think we can get frosts with temps as high as 38F.

Yes, that's what I mean or 32 F

Sorry but I dont understand this. 38F is 3C, right?
Do U think with strong wind or somehow?

harveyc

Yea, about 3c. No, winds decrease the chance for frost. I don't understand it very well but Joe Real once explained how heat radiation to outer space draws heat out and forms frost even when air temperatures are above freezing. It happens all the time, most of our frosts occur about 32F (0c). We had about 30 days of frost last year (more than the prior several years combined) but we probably only got down below 32F a few times.

There are lot of differences in our climates. In our case wind (North wind) incerase chance of frost.
Another thing is that we dont have souch high oscillations in day/night temperatures as you.
We dont go so low at night but also not that day high as you.

It has been an unusually cold November in our area. I'm glad the rain as started and I hope that'll give us a break from the cold.

The habaneros are doing worse than the bananas. There goes my idea of a banana habanero salsa.

Conejov - thanks for reminding me! I'll put some mulch on bananas!

North winds increase the chance of freezing here, but do stir up air in those cases where we're above freezing temperatures, so the chance of frost then decreases. Our very coldest nights are calm nights following a period of north winds such as we had in January 2007 when we had several days where we stayed below freezing and reached the low 20s (F).

And what area might that be? You might want to edit your profile to include your approximately location.

We were at 37F at 11pm last night and I thought we'd have frost again this morning but a storm front approached so we didn't drop any further and didn't get frost. We now have high winds (gusts expected up to 45mph) and rain. Great for ducks!

You guys should move over here to Greece! Winter seems to be still far away.
November average so far was about 3 - 4° C (5 F) to warm (mean temperature) and our low temp was 4° C (40 F), but only one night. Usually it's about 8 - 10° C (45 - 50 F) and around 20° C (70 F) during day.
But it should be getting colder soon. My nanas still like it oudoors. Even my little baby AeAe get a few hours outside every day...

Harvey, will do. I'll get my profile edited by this weekend.

Who has had luck getting bananas to produce in the bay area? Which varieties? Any pixie dust I should be aware off?

Thanks,

Sid

Sid, I'm just NE of Antioch and have bananas on a plant right now and there used to be a guy named Mike in Antioch that fruited bananas and I'm sure many others as I do see bananas around the Bay Area from time to time, but I think many folks there do not get warm enough weather to get them to flower early enough although they may be an areas which are mild enough for bananas to survive unprotected. Maybe the need to try Veinte Cohol, etc., fast flowering/maturing varieties.

Maybe we should send Al Gore to Greece and the cold weather will follow in! :ha:

Harvey:
My Viente Cohol is over a year old and still look like a pup. It won't grow anymore at 2 1/2 feet with small trunk about 2" diameter. The ambient tempt probably is the cause. It's time to move to San Diego.

Man harvey. You get a lot of cold temps and frost out there in the delta. I wonder why? And yes, in CA we do get frost on still calm cold nights. At 38F? maybe yes I guess it is possible. But temps are recorded at 6ft high where it might be 37-38 and at the ground level 32. It still needs to be 32 to form frost.

Frost - Wikipedia, the free encyclopedia (http://en.wikipedia.org/wiki/Frost) Here is an article for all of those interested in the different ways frost forms

The air does not need to be >32 for frost to form.
Surfaces (like banana leaves) loose heat to the clear night sky and their surface will be coler than the sourounding air...leading to frost.

TommyMacLuckie

That's what's confusing. Everything I've read about frost says it's commonly confused with meaning 'freeze' when in fact it needs to freeze for frost to occur.

That's just what I've read. Me I've never had any problems with a frost, only with freezes. 33 degrees and my bananas are fine. 32, eh, not so good. 31, bye bye fronds.

So I don't know. I always thought frost was in low areas that act as pockets, trapping descending colder air, similar to an area that is low, like a delta, compared to hillsides because the cold air sinks.

But then getting frost on a wind shield without a freeze happening...so obviously something gets colder than other things.

Hi friends,

First of all, I am surprised to know that it had already fallen frost in Sacramento.

In the pacific coast of central Japan, it had dropped down to 37F in these
days. But there was no damage at all to my bananas yet.
For safety, however, I have taken Dwrf. Cavendishes into the house leaving
other comparatively cold hardy bananas outside that I am planing to perform
anticoldness protections.
During the coldest season, it drops even to 25F.

Frost hasn't yet fell in Sacramento, but the cold outlying areas yes. demo meccha samui da neee. Dwarf Cavs don't like cold, so good idea:)

I think it probably has had frost in Sacramento. I lived there for many years and it's very similar to what I have here in Isleton. Up higher where you are at I'm not surprised you haven't had frost yet. Folks down in Modesto and south had frost a couple of weeks before me. This is one of the earliest frost years that I remember and I've been around here for 52 years.

Okay you're probably right. Probably not downtown/midtown though due to urban heating:D It's zone 10A in some spots so doesn't really speak for 'Sacramento'
