Frost

15 posts in this topic

I thought I'd start a thread about frost after seeing very thick frost this morning. How often does your climate get frost (if it even does)? Where are you located? Are you in a cold/warm microclimate or have any? Here in Virginia, near Chester, we get frost commonly during the Winter and late Fall. Tree canopy (I use Leyland Cypress for this, it works well) and close proximity to water can protect places here from a lot of the first frosts. Here was the frost this morning, the first picture is from my front yard (exposed to the West) and the second picture is from a lot with Leyland Cypress in it. Notice how the closer you get to the Leyland Cypress the less frost there is. Also keep in mind that this was a pretty heavy frost. With light frosts, it is common for places with dense canopy above to get no frost at all.

In the front yard, at least a mild frost each year before I put the oak in there.  Now, the area where I see frost is diminishing as the oak spreads out.  In the back, I've never seen frost on the ground under that big oak.  I'll probably get more frost on the other side since I had to take one of my avocado trees down.

My neighbor took this awesome/beautiful photo on her property this morning, about 1/3 of a mile to my west.

We had patchy light frost on our property. The difference?  We do have a good number of large trees on our property opposed to the open pasture....but we are also about 50’ higher in elevation.

San Diego, Tijuana does not get frost. If I read correctly, the last time it snowed in San Diego/TJ was 1968.(may be off by a year). But still we do have cool winters.

I'm just outside the northern city limit of Mobile; frost information (50% probability @ 32°F) is as follows:

Last Frost Date: February 28

First Frost Date: November 29

273 freeze-free days iper year.

My property has about 30% coverage from a giant live oak. The areas most protected from northerly winds are in the dappled shade of this tree.

Had my first big frost and freeze this week. Even though I had a low of 24F and clear skies the humidity was still 83%. My car underneath a large fir tree never has frost.

It's not when you get it as often as we do in the winter.

So which is the worst, frost or snow?

Frost, it wipes out all of your tropicals (that are tender) for the season. But, if you have to go somewhere and there is snow, have fun. I guess I just like snow more. I don't mind "warm snows," like snow when the tempature is no colder than say 28 degrees F because you can go out in it and the palms (hardy ones) will be fine.

Have to agree with @PalmTreeDude. Snow 9 out of 10 times means the temperature is over 25f(usually closer to 32f) and melts the next day and even acts like an insulator. There was a scientist on Solomons Island that used the, rare for them, snow to insulate his palm and it was as tall as the building! Frost kills way worse. 

 

Honestly I'd rather not see either ever again for the rest of my life!

We typically have a handful of frosty morning each year - usually accompanying 34F or 35F nights. So far we have not dipped below 40F and the forecast has us above 40F through Christmas. Hoping for the best as January arrives.

Last night we had a low of 53F with multiple lows in the mid 50s over the past week. Yet we had frosts on 27th Sep and 3rd Oct, but no frost since then. The nights have got progressively warmer the further we head into winter, which is very odd. We had some real cold nights in the last week of September / first week of October, but we then experienced a warming trend with no more frost up until now. I'm not sure how late September can be colder than early December (in the northern hemisphere)? Very odd. Although that is due to change in the coming days with possible frost forecast...

    • 2018/19 Winter Low Temps
      By PalmatierMeg
      About this time every year someone starts a thread about Winter Lows in the Northern Hemisphere. Such a thread is somehow therapeutic for PTers anxious about how cold may affect their palms - at least we know we aren't alone. So, I'll kick off this year's discussion.
      This morning was the lowest temp since last March: 48.4F      Predicted: 46F     Current temp: 56.3F at 10:30 a.m.
      Tomorrow's predicted low: 43F
      Then a warming trend until the next cold front. I am making no attempts to move/protect palms at this time. After sunup, temps rise quickly.
    • Cut My Bananas Down For The Season
      By PalmTreeDude
      I cut my banana trees down for the season today, this was their second year of growth. When I first got them I got one small sucker from my neighbors bananas that he dug up for me, it barely had a root on it. I planted it, and it multiplied over the two years of having it. Keep in mind these get a lot of shade in the summer, so they are not as fast as if they were in full sun. Here are the trunks, which I also cut down. I dug up two very small suckers that were just coming up. I am going to try to grow them over the winter in pots. 


    • Final Cayanne Pepper Harvest Before The Freeze
      By PalmTreeDude
      So it will be going down to 25 tonight, which means all tropicals will be killed for the winter, the only are around me that may be spared is the islands in the reservoir, but even they might not be saved by the water. They have not had a single frost yet, even the areas right along the lake did not frost yet (I can tell by the completely unharmed bananas a trees along the water). My Cayanne Pepper plants will be killed by tomorrow. So I did my final harvest. 

    • Winter Tips for King Palms (9B)
      By Palms916
      Still very new to growing palms, so all advice is greatly appreciated. Just wondering if at this size of the king palms (c), does the occasional mid to low 30’s every now and then require any protection? They receive full sun daily, as they just battled our brutal hot summer sun. Winter over nights usually, down to mid-low 40’s or upper 30’s for a couple hrs. Occasionally dipping down into the low 30’s at worst a few nights throughout December-January. Daytime weather in Dec-January upper 50’s - low 60’s. But plenty of sun light year around
    • Confusion about Coconut Palm hardiness
      By Jake
      So I’m planning on moving to the Emerald Coast after I finish my EMT-P. From what I’ve seen, it’s mostly Cabbage Palms, Canary Island Dates, Windmills, and some California Fan Palms. 
      The area seems to have most everything I want, but I find it slightly upsetting that Cocoa’s cannot grow there! I did some research on the subject and found that Pensacola and Panama City are both 9a USDA zones. Not surprising at all.
      Now this is what throws me off; Multiple websites I have seen say that Coconut Palms are “..great for growing from 9a to 11..” Is this information just plain wrong? I’m just confused as to why no one would plant these in the panhandle if they are able..?
      Thanks for your time,
      - Jake
