Phoenix roebelenii

[iwan]

Still working on the temp numbers, but 16 out of 18 days below freezing.  Most days 12+ hours below freezing, rebounding to mid-40's.  Official lows in Madera and Fresno in low 20's.  Some frost every day, but nowhere near as heavy as normal 28-32F freezes.  I measured mid-teens F at 18" in one part of my yard.

OOPS...  Forgot to bring these in.  Back to Home Depot!

In a ~30g tall terracotta pot next to house, some protection from eves and surrounding Canna.  10" pot size.  This had been uncovered during the Dec 2006 freeze (~24F) with no damage and was unprotected the first couple of days of this freeze (recorded 24F nearby).  I started throwing a heavy blanket over this as the freeze got worse.  Being compressed by collapsed Canna stalks.  Foliage appears dessicated, about 60% damage.

4' tall plants with no overhead protection got moderate leaf burn from 5 hours plus of frostless 27F in the San Fernando valley.  Two other palms on the other side of the house, also no protection, were undamaged... though about 4' from the house.

Turns out, after closer inspection 2 weeks later, all Phoenix roebellenii in yard, save some under significant protection, severely burned to nearly defoliated (just took time to show up)- these plants are 4' tall and no protection.

Forgot to add.

A store in Fresno has a dozen or more single trunk roebelenii with 3-4' of trunk in 24" (maybe 36") boxes.  They were substantially burned.  The store was closed and it was too dark to take pictures.  I will be watching these.

Disappointed in this one. I have a tight cluster of three palms all with approx 1’ clear trunk. They were planted 2.5 years ago about 3’ from the house with no overhead protection. Until now they have been exceptionally healthy, vigorous, and never shown any cold damage.

- At 27F with frost about 10% of the foliage was moderately damaged.

- During the colder weather (min of 22F, no frost) I put x-mas lights under them and covered them with a frost blanket. 90% of the foliage was moderately damaged, but the plants look like they will survive.

Many multiple trunk plantings throughout yard, all 3-5 feet tall, all 90-95% burned after 24F low and multiple nights below 28F, no frost.  To be fair, there was slight earlier frost

damage on these, from December frost events.  I expect them to recover this spring and will edit this post reporting later.  All planted with no protection out in open.

_{I have a triple that was completely defoliated from multiple low 20s and 2 spear pulls. I seriously doubt it lives.}

Wimpy palm - I have a triple that was 70% defoliated from overnight lows of 28F, covered in frost cloth in the warmest part of the yard under canopy.  Not worth the grow if you get frost, ever.
