Winter 23/24 in UK & Europe with an early freeze! 1 2
by UK_Palms- 50 replies
- 1.5k views
After the crappy winter last year, it seems we are going to be starting this winter with below average temperatures as well. Far from ideal. Thankfully it won’t be too extreme as it is quite early on, limiting the extent of cold, but it is still quite a significant cold wave either way. And this appears to be effecting almost the entire continent too. This is coming down from Scandinavia and the Siberian arctic. Any cold will be heavily moderated / watered down by the seas around the British Isles, before it arrives on these shores. Here are the ECMWF and GFS runs. They are very similar looking now… both rather cold and wintry. I don’t …

Winterizing contradictions
by Than- 16 replies
- 357 views
I am considering winterizing methods and I read lots of advice online. However, some of them seem to contradict each other. Can anyone help me clear the mental fog? 1. Cover plants under tall evergreen trees to stop frost from falling on plants and also to trap heat VS use deciduous trees so that sun rays can pass through in the winter and warm plants up. 2. Mulch the soil around the soil to insulate it VS keep soil clear because it absorbs heat during the day and releases it during the night. 3. Keep the soil dry during cold spells to avoid freezing the roots VS water the plants because wet soil absorbs much more heat (again, if there is mulch on it, how c…

Palm growth in the fall/winter
by Ben F.- 1 follower

Hi all, I was curious about palm growth in the fall/winter. I'm in Southern California, zone 10a/b, it doesn't get much colder than upper 30's in the late fall/winter, typically not warmer than lower 70's during the day. I was curious about how palm trees grow during this season, specifically Queen palms. From what I read, they are still growing, but once the soil gets colder, not as much? I've noticed more palms around this area, including mine, seem to be doing the nutrient pulling from lower fronds (more yellowing), while still growing new fronds. Is there something about this time of year that makes palms use more of their own fronds, rather than nutrients/fertil…

2023 Atlantic Hurricane Season 1 2 3

That time of the year is still several months away, so dont worry about it yet. But, why am I making this thread then? We have Invest 90L off the east coast on...*checks date*…. January 16th! This Invest area is not expected to really do anything, and has been tagged with a 0% chance of development by the NHC today. Satellite data indicates that it *may* be a Subtropical Storm, but this is such a marginal case where it may or may not be that its best to just wait to call it anything until post season analysis. A lot of studying will go into this system im sure. 90L will go on to impact Nova Scotia and Newfoundland with gusty winds and rain. Heres some satellite …

Cyclone Ciarán (northwest Europe)

So it looks like this storm system is going to smash straight into us in the next 12-24 hours. I was hoping it would head further south and go through France, but it looks like the eye of the storm will pass directly through central England now, with the worst winds on the southern end of its tail, affecting the south coast of England and northern France the worst. The latest run on France’s AROME model has 150kmh+ winds over the Isles of Scilly and exposed parts of southern England. The Channel Islands of Guernsey and Jersey looks like they could be devastated, potentially with 180kmh winds. AROME is a fairly accurate model in the shorter t…

Some interesting Hardiness zone research

I was doing some web browsing and found an interesting page showing how much hardiness zones have shifted. I'm not sure if this has been posted here before, but I thought it was quite interesting. Closest city to me is Albuquerque, and it lines up with what I've noticed anecdotally. Overview of the research. https://www.climatecentral.org/climate-matters/shifting-planting-zones-2023 See the graphs showing the changes https://www.climatecentral.org/graphic/shifting-planting-zones-2023?graphicSet=Local+Shifting+Planting+Zones&location=Anniston&lang=en

thermal mass Impact of Common Landscape Materials
by kinzyjr- 2 followers
- 12 replies
- 697 views
Overview The purpose of this thread is to record observations of surface temperatures and their change over time under various conditions for common landscape materials. Most of us would assume that the borders and other materials we use to landscape our yards are relatively close in heat capacity, with albedo having an impact for the darker materials. This falls in line with the interest in urban heat islands (UHI), since having some of these materials near small plants may give them a boost overnight if they can hold enough heat. Landscapes with a lot of hardscaping may be able to gain a small advantage, especially if the grower is able to cover the plant in a w…

Was lucky to see the "Ring of Fire" eclipse on Saturday morning.. It made beautiful and striking shadows that shimmered.. here are some pictures I took of the shadows.. coming off my Washingtonia Filiferas and Eucalyptus.. It was really fascinating..the weather was perfect for it..not a cloud in the sky. Im also attaching some of my weather station data which recorded a temperature drop! I figured Id share because from what I understand it won't happen here for another 300 years!

Hurricane Ian damage to Bismarck
by Venice Strong- 12 replies
- 1.4k views
Last week’s Hurricane Ian pounded Venice FL with 115+ mph winds. Our beautiful 25 foot Bismarck suffered extensive damage to the northerly facing fronds. Several southern facing fronds are still attached. Our landscaper said that the center top frond was lost (containing the white spongey core material) and has no chance of survival. Has anyone had experience with this center core loss and what are it’s chance of survival?

What causes these "anti-microclimates"?
by Pee Dee Palms- 1 follower
- 16 replies
- 1.1k views
Recently I was looking at some USDA hardiness zone maps for Texas, Louisiana, and Mississippi and noticed something off about three different towns. These three towns that I have posted pictures of all seem to have a lower hardiness zone than the surrounding area which I would think should be the opposite. I thought that the asphalt and heat the buildings and roads create could potentially bump the hardiness zone up half a zone like most large cities. Why would these three towns be half a zone below the surrounding area? The three towns in question are: Pearsall, TX - Baton Rouge, LA - Vicksburg, MS

Hot Water

..This tweet from Scripps Oceanography today, and yesterday's SST readings via "State Of The Ocean" data from Southern CA. say it all.. Have been hearing about the 65+ Dew point readings across coastal San Diego county lately. Data from the State of the Ocean site is Sea Surface Temp. anomalies, not the actual temps recorded. From Scripps twitter page.. State of the Ocean SST anomaly data from 8/2/2018 across S. Cal. With this summer's stubborn high pressure looking to set up on top of the region again over the weekend and possibly through all of next week.. could Scripps record that magic number of 80F? ..Must admit i'm a little envious regardless.

Well I thought I’d start a new thread. I’m looking forward to a good growing season this year. Spring isn’t really here yet, but winter is slowly releasing its grip. By the equinox things start to really improve. Today is cloudy with rain returning tomorrow. A min of 12.5C this morning with a top of 18C forecast. The garden knows spring is upon us soon. The deciduous trees are in bud burst with the grapevines swelling there buds. My Rhopies, Howeas, and Archontophoenix are all opening spears in anticipation. Bring it on.

Is the climate of Dallas closer to Minneapolis or to Miami?

This same topic was made and exploded on the ol' City-Data Weather: https://www.city-data.com/forum/weather/3375676-climate-dallas-more-similar-climate-minneapolis.html Emman85 (a member both there and here) participated quite a bit, but to my knowledge no one else on here did, so I figured to make it here because you folks here on Palmtalk might find it of interest. Not just for the comparison between the climates, but for its overlap in premise with much discussed climates on here. Here's the comparison and contrast that overlaps what we discussed. "Dallas may not have continental winter temperatures but it does get continental winter patterns and can …

This was planted by a landscaper about 6-8 months ago and the original grinds started turning brown but the new ones looked ok. We have tried increasing water but it’s getting hotter and now the new ones growing from the middle look dry and yellow and unhealthy. I think it get 20 min of water every morning at 6 am. Anyone have any help or tips… I don’t think my landscaper knows what to do to make sure it doesn’t die help! Is it look better to anyone then I am thinking? I am worried it’s too late already and 120 degrees is coming!

length of nightly cool down and plants
by flplantguy- 1 follower
- 9 replies
- 728 views
Like the title says, Im wondering about the length of time a given location reaches its low (high) temp for the night (day) and the effect on plants in the garden. If the time is only minutes (like a light freeze) does it have any effect at all? If a plant likes cool nights and its warmer before a small drop at sunrise can you even count it? We average out numbers for plants in heating and cooling degree days for this purpose but its more for farming and less for plant microclimate. In Florida inland locations cool more than the coast and warmer nights are an issue on the water, but what about the adjacent lands that hit lower temps for short periods? How does that ef…

Why Southeast US Airports Are Often Cold Spots
by Can't think of username- 19 replies
- 998 views
All my research into why the Tallahassee airport official weather station is such a cold spot has taught me a lot as to why other Southeast US airports are also cold spots. To give those who missed those comments some context, the Tallahassee airport is a cold spot that has colder lows than many other places in the Southeast US because deforestation surrounding the airport leads to massively disproportionate soil drainage and ground/sky exposure that are both apt to make readings colder on the clear, calm, nights that are all too common in the Southeast US. 3 studies have been conducted on the matter and I can recommend all of them. https://www.researchgate.net/publi…

Coconut Palm in Sarasota, FL?
by Emarohl- 1 follower
- 20 replies
- 2.9k views
i just moved to Sarasota and am starting to plant trees in the backyard. I recently bought a small coconut palm maybe about 2-3 feet tall and planted it outside in our yard. I was wondering if anyone had any thoughts or advice on a coconut palm growing here. I know they aren’t very cold hardy. Our house is less than .5 miles from the Sarasota bay and west of highway 41. The yard gets plenty of sunlight and has good drainage. Will it be too cold for it to survive? Can I cover it in cold snaps to keep it warm? Coldest it got this year in our area was 38 deg. According to maps online we are right on the cusp of 9b and 10a. Wondering if anyone in the area had experience with…
