Don't worry about it. Despite what you think, citrus can take frosts very well. All of mine went through our January 2007 freeze. Temperatures dropped to the low 20s and even to 18F for two nights. No damage.

Oh, wow, great info! Thanks! Are yours in pots or in the ground?

Eight were in the ground at the time of the freeze and one was in a five gallon container. One of the ones in the ground (a variegated pink lemon) had been recently transplanted one week prior to the freeze.

Excellent! You have made it possible for me to sleep tonite. I can't thank you enough!

It's supposed to be 24 up here and I just put Christmas tree lights in my trees.

Your welcome! i'm glad i could help ease your mind. Keep warm tonight, it's supposed to get pretty cold. I'm forecasted to get to at least 30F tonight (Fresno). I'm a bit worried about my pachypodium lamereii. I've got it covered with a large net. We'll see how it fares.

It is very unusual in Z9 to get a significant frost when there is precipitation or there is any significant cloud cover. I know it is clear tonight, but you didn't need to cover the plants when it was raining. Well hydrated plants are also less likely to develop frost damage.

An update from Lake Elsinore - I left the xmas lights on the trees and it got really cold here last night, but it also rained continually through the nite, so I hope they are OK. I just checked weather.com and the low last nite was only 39, forecasted to be 31 tonite, and then start warming up slightly. I am unable to really check on them until the rain stops, but they look OK from the window. Will keep updating you. Please update me on your situations. Thanks!

So far, the Christmas tree light are keeping my citrus trees safe from the frost here in Orland. We have more cold nights ahead.

OK, update time. Last night was the lowest yet at 34 degrees, after 2 days of steady rain. There is snow on the foothills next to our house. Yeeks! Very unusual!

Anyway, my beloved citrus seems fine, my fuyu persimmon and my brown turkey fig also seems fine. These low temps definitely are bringing on dormancy for these two! Tonite should get down to 32, so I will report again tomorrow.

The really cool thing about all of this is that I'm learning a LOT about growing citrus in containers. From 107 and bone dry to 32 and soaking wet in just a few months. Wow!

How is everybody else doing?

OK. another very cold nite, could have been as low as 28, which weather.com recorded. Might be a record for this date. Anyway, trees and fruit did fine without lights or covers! Yay! Heavy fog this morning which could have helped a lot.

Will keep you informed. Anyone else?
