Five specimens, down in my Valley of the Kings.

About four feet tall, 2" at the base, a year or so from 5-galloners.

One night, 27 FF, trashed, fronds black as an executioner's heart.

Sad!

Have 2 potted of these. 1 an avg 5 gal, other a nice 15+ gal size. Did nothing the first cold night (friday) Read all the posts, then checked and covered the remaining nights. Hit 29F, small looks bad, 15 gal has measles, and lower leaf actually looks good.

Zone 10a at best after 2007 AND 2013, on SW facing hill, 1 1/2 miles from coast in Oceanside, CA. 30-98 degrees, and 45-80deg. about 95% of the time.

I do some experiments and learning in my garden with palms so you don't have to experience the pain! Look at my old threads to find various observations and tips!

Have 2 galon plant no trunk next to remote sensor that read 29 and looks perfect.  It must be noted however that is next to the house amongst other potted palms, not sure how much difference this would make.

Will it come back in the spring? Make sure you spray the leaf base, where they come out.  The crownshaft looks pretty nice.

The password is OUCH.

I had five specimens all exposed to three nights of 24.8 F (-4.4 C) and a fourth consecutive night at 27.8 F.

But, it's starting to recover, like all of its brothers/sisters. . . .

Two 15 gallon size planted in 24 inch boxes this last summer.  Had two nights at 25f  no frost and a third night at 29f with frost.  Both palms had been wraped at the base up to the crown and still every frond on both palms witherd like the one pictured above.  But I am happy to report that as of 2-17-2007 there new amerging spears are starting to open.  Maybe by the end of summer they will start looking like palms again.

Both of my previous mentioned maximas have pushed a spear and are about 1/3 open. all the past leaves are pretty much toast. Looks like they'll come out OK eventually.

My A. maximas are about 16 feet OA with 7 feet of clear wood. Damage was shown after 29F, about 25% leaf damage. These things come out of burn faster than any palm I know.

Lost my only two remaining maximas this year under moderate cover (about four years from seed).

Definitely wimpier than cunninghamiana here.

I have a 10 year old a. maxima 15 feet tall, it has a reddish emerging leaf. It's a fast grower, but fronds exposed to clear skies that high off the ground do burn when temps are 30F or less for more than a couple of hours. However, under canopy, this palm can take considerably more cold.

31F Dec 7th for a couple hours some minor damage no overhead protection. Might have had frost as it was on the rooftops. It is right next to a large cunninghamiana that had zero damage.

Here is the tree overall

IMG_0449.jpg

About 5ft away is a Hibiscus with zero damage at all so I am sure the 31F is correct.

I will always cover it from now on below 33F. Didn't realize they were that wimpy. I have another much larger maxima under canopy and it is unfazed.

Really? Why so late? I think late January will be a good indicator when everything starts growing again

Not sure why. I didn't see full extent of the Dec 2013 freeze damage in Fairfield till March at the earliest. Some plants that appeared unscathed began to rot where tissue had died. Perhaps the rising temps and longer days allow plants that are on the edge to tip one way or another
