Recent reader, new time caller. I live in Tampa, FL and have a Canary Island Date Palm that was recently diagnosed with palmetto weevils. Our local arborist was not able to come out quickly, but successfully and accurately diagnosed it with images and a phone call. Despite everyone that I spoke with saying that the tree should be pulled, I read some guidance on this form as well as from a You Tube video suggesting a few courses of action, including:
Fertilome Tree & Shrub Drench Gallon and
7.9% Bifenthrin Concentrate for Insect Control, which as the gentleman in the video (who was dealing with severe issues in South America suggested), I applied by drilling into some of the lower fronds with a 1.5" auger bit in order to spray the Bifenthrin into the bud. I also dumped some fire ant powder into the top of the bud, again something else that I read on a forum. I was desperate and was trying whatever I could. I only removed fronds that were drooping and brown with weevil tunnels...trying to give the tree a chance by leaving the greener fronds (mainly on one side as you will see). And I have remained patient.
That was all back in March, it is now Mid May. I've done some repeat application between then and now of the Bifrenthrin. The fronds that were not infected have held up all this time (see pictures). And most recently, there are some frizzy new frond spikes that have started to emerge (again, see photos). My question to this illustrious group is, (a) is this actual new growth, (b) is there any chance this palm will survive and recover to some sort of decent life, and (c) at this point, what should I do to help the palm?
Thanks in advance for the replies. This is a whole new ordeal for me...not necessarily the greenest thumb, but I've put in a lot of effort. If this guy survives, I'm popping some serious champagne. Be well!
This topic is started to document the cold damage, or hopefully lack thereof, due to the cold spell.
Initially, it looks like most of the damage done locally was due to frost. As you get outside of town, the damage can get pretty severe on the "high-9b/low-10a" palms that have become more common due to the advent of Lethal Bronzing. I'll begin with this photo I captured west of the airport on Medulla Rd. The damage didn't even wait for the warmup to manifest. For my own garden, I'm going to wait until it warms up to do my report. There may be palms that look undamaged now that will show damage after the next three days go over 80F. There may also be palms that appear to have light damage that have more extensive damage than shows at first.
@GoatLockerGuns was kind enough to compile his results from the Texas 2021 freeze in a spreadsheet that was easy to import into the Cold Hardiness Master Data. If you'd like to do this as well, I can assist if necessary.

For those who haven't been to this garden for either of tours or for a personal showing, you're missing out. Luckily, not for long. The new botanical garden is slated to open in Fall 2022.
For those familiar with the thread in the Travel Logs regarding Dr. John Rossi's Garden tour for the joint CFPACS + FCPCS meeting, you know how wonderful this garden was the first time. Now, the private garden is taking the next step and will become a botanical garden and nature preserve.
CFPACS and FCPCS had their Joint Holiday Meeting this weekend and were treated to a preview of coming attractions. Currently, the garden is home to over 300 species of palms and over 50 species of cycads. The garden also includes an area of "untouched" Florida, with tons of Sabal minor, Sabal palmetto and Serenoa repens under deciduous hardwoods.
You can see the new website here: https://www.stjohnsbotanicalgarden.org/
Here are a few photos from the meeting/preview:

Hey all. Haven't made a post of my own in a while, so I thought I'd share some of my potted palms that I keep on my patio here in zone 10A in southern FL. PLEASE disregard the somewhat messy patio at the moment. Thank you! its a work in progress!
In April of 2021 we had to move from our place which was on Maximo Point, the southern most tip of mainland Pinellas county. There, we were about a mile out into Tampa Bay on a small, less than 1/4 mile wide strip of land that ran along I-275 leading up to the Sunshine Skyway Bridge. We moved about 2 miles away to an Island in Tampa bay that is probably a bit smaller than Key West, called Coquina Key. In front of the new place is a fairly big salt / brackish lake, and behind me is a large body of water called Big Bayou. Once again we are still surrounded by water in very close proximity. The Patio faces South / Southeast and gets full sun in summer until about 3-4Pm. Winter we will get it at a lower angle, and for most of the day, keeping us warm. The building will protect us from the chilly NW winds from "cold fronts" that occasionally come through during "winter" lol. Its really more like "wet season (summer) and Dry Season (winter) here as the winter temps, while cool at times, are still nothing really close to actual "winter temps"
In these photos there is nothing rare or particularly spectacular, but they are all palms that I love. Dypsis Lutescens, Adonidia Merrillii, Phoenix Roebelenii, Chamaedora Cataractum.
First two pics are of my whole patio on the 4th of July 2021. Second of the first two is my newly (at the time) repotted Pigmy Date Palm. (Phoenix Roebelenii) It now has several feet of trunk. It was purchased in early 2018 and had one very small one, and the main trunk which at that time had about 4-6" of "trunk". It was much shorter. I removed the very small one to allow the bigger one to have the pot all to itself and so far its flourished.
The rest of these photos below were taken today, 8/11/2021.
Below: some large Dypsis Lutescens in "half" whiskey barrels. They were pretty large when I got them in late 2017/ early 2018, but had no clear trunk.
Now there are lots of clear trunks on them
Below: Adonidia Merrillii. Purchased in mid 2018 for $25.00, it was fairly small and trunkless. It has done fantastic in this pot since, and will be getting an upgrade this year.
Below: Phoenix Roebelenii.
The following 3 photos below are my water HOGS, Chamaedorea Cataractum. They were fairly small when I got them 2 years ago for $10 each. They have grown great,
and are now loaded with seeds. These things are WATER HOGS. I have to water then daily if it doesn't rain, sometimes twice daily each, and they need to be
DRENCHED / FLOODED each time. They are much happier on this patio as its less windy. It is still pretty darn windy here, but no nearly as strong / ongoing for hours on end
as it was at the old place.
