My yard was hit with the first frost of the year. There was frost all over my car and the weeds in my front yard were also iced over. I hope everyone’s plants are doing ok. There is another frost advisory for tomorrow.

Yep diffidently 'Yukon Express" coming thru -30F on ground this morning! We did a quick covering with frost cloth over top's of most plant's no covers on Cherimoya's will by week-end what kind of damage! Stay warm!

35 and no frost up on the mountain.

Spaugh, that’s great news, I was worried the plants were going to get fried.

I’m sure I’ll lose most the new growth on my Mangos and Lychees. I think everything will survive.

Simon, we got frost as well in Clairemont (92117)... unusual enough that I snapped a picture of the frost on the hood and roof of my truck.

Haven't had a chance to check the trees.

simon_grow · « **Reply #10 on:** February 20, 2018, 04:44:54 PM »

I get some minor frost almost every year but today’s frost was a little thicker than in previous years. When I scrapped my windshield, the ice particles were large enough to scratch my windshield but just barely and I stopped before I caused more damage. Tonight’s going to be another cold one so if you have a frost advisory in your area, take your plants in now. I hope everyone’s plants make it through.

Chula Vista was 38 last night, I didn't notice any frost. Simon, I thought you were up enough not to get any frost.

ScottR · « **Reply #12 on:** February 20, 2018, 06:57:15 PM »

The only damage so far is young tender growth on plants because of our previous Winter high way! Will be cold the rest of this week up here! But possible rain on the way we'll count it when it hit's the gauge!

Badfish8696 · « **Reply #13 on:** February 20, 2018, 07:08:01 PM »

Spoke too soon about the mild winter in the thread I posted the other day. Last night I had significant frost with several hours below 30 and at least two hours below 26. My avocados look terrible, you can see tons of brown spots on leaves, brown stems, black shriveled new growth, wilting blossoms, and just walking through the grove you can smell decaying leaves. Luckily only a few varieties were blooming. I fear the trees will have significant defoliation. So much for that foliar fertilizer application I just did. Have little faith in a bumper crop of avocados this year but we will see.

The citrus are largely fine, minimal damage to some that had a smidge of new growth. Mexican lime has leaf drop as always, though it was blooming prolifically so will probably loose fruit set there.

I am guessing if I had a mango in ground it would have been destroyed by this frost so I am rethinking planting one of those now.

Banana looks okay. Some burns on tender pomegranate leaves. Burns on papaya leaves not covered well enough.

Hey Mark, I’m literally on a flat Mesa where cold air settles. Just a mile away from my house down in Sorrento Valley, the temperature was reading 33F because they are at a lower elevation.

Leo is just up the street from me but he is on a hill so the cold air drains much better than compared to where I live. I have patio heaters for extreme cold weather events but I’m not going to turn them on unless it’s one of those rare 10-15 year hard freeze events.

Samu are your stone fruit flowering and flushing now? I have some trees with big fruits already and others are completely dormant and bare. Im hoping this week of cold will wake them up.

CBG35 · « **Reply #18 on:** February 20, 2018, 09:56:55 PM »

Simon,

I noticed that all of my mango flower panicles were droopy this morning, after the frost. Does that mean they will die and the trees will likely re-flower? I haven't had a frost like this for 3 years. Also, some leaves turned partly brown.

Sorry to hear about this freeze. We were hit hard in central Florida in January. February has been record breaking heat the whole month. I think all but the first two days of the month have been over 80* and mostly 60+ degrees at night. Our forcast is hot for rest of month but I hope we don't get any insane cold front in March. Everything is growing and blooming about 3-4 weeks earlier this year compared to last year. Just watched an interesting video from a guy (plant abundance) in California using sprinklers to protect his blooms. I'm looking into a sprinkler setup myself for part of my project. Hope I don't get to test it this year. Hope you all make it through well.

Yes, I noticed a couple of stone fruit trees started pushing nubs and even few flowers popping sporadically; but no big fruits like yours, Spaugh! (Interesting, how could that be ? Please talk about it at the Temperate Fruit section).
Yeah, this cold nights are good to our stone fruit trees that may require a certain minimum chilling hours. (But unfortunately is the opposite effect to our Tropicals...

The florida prince peach already has golf balls all over it. It is always really early to ripen.

No action on some of the others.

barath · « **Reply #23 on:** February 21, 2018, 12:23:52 AM »

I think last night's cold was unusual in that there was no inversion layer, so areas closer to the coast and at lower elevation were warmer than higher elevations. From what I heard, that's because the cold air basically replaced all the warm air and so there was little opportunity for an inversion. Here in the East Bay the areas near-ish to the water, like where I am, stayed above 35 F but I think some inland areas got frost.

Mugenia · « **Reply #24 on:** February 21, 2018, 02:25:57 AM »

I will be the first one to say it. It's Trump's fault. I blame it on him.

It's cold like hell around Mockingbird/Markham area in Riverside, but there's no frost. The low was about 34F and windy. Hope there's no damage to our young trees.

simon_grow · « **Reply #25 on:** February 21, 2018, 09:20:17 AM »

I didn’t get any frost this morning and hopefully the cold front has moved on. The temperature was 40f at my place this morning. I have some minor frost damage on Younger Mango leaves already showing but everything else looks good so far.

We bottomed out at 32F i can live with that

joehewitt · « **Reply #27 on:** February 21, 2018, 10:53:03 AM »

Here in Los Gatos it got down to 32. A bit shocking given that my brain had already switched into "spring mode" from that stretch of high 70s earlier in February. Too early to assess the damage, especially given the 10 more days of near-freezing temps in the forecast.

I was relieved to see that many of my most tender plants, like Jackfruit, Babaco and Green Sapote, had no frost near them because I planted them near the canopy of large oak trees. Others, which are under open sky, like Carambola and many Cherimoyas, had light frost on their leaves. Considering that most winters we dip down in the 20s repeatedly, I am still counting this as a mild winter.

Went to bed in the East Bay expecting the forecasted 32F, woke up to 26F. Amazingly little seems to have died (even some dragonfruits I left out on the patio). Eugenia candolleana didn't even drop its leaves. Hopefully the coming weeks don't reveal more casualties.

Frost damage usually raises its ugly head in days/weeks to follow, some results are immediately the day following to 3 days, some struggle to hang on and die in 2-3 weeks. again, keep roots warm, you can lose limbs but save roots and bottom few feet and plant will grow back up.

On Tuesday night, where I live in So Cal, it hit 28 deg F for 3 hours (5 hours total below freezing). Last night, it only hit a low of 30 deg F and was below freezing for 4 hours. Data from El-USB attached to a Mango tree. Panicles have all completely wilted. Leaves have some browning, but otherwise the trees don't look too bad. Posting so others know the cold tolerance of Mangoes. 30 deg F was okay, but 28 for 3 hours was damaging (but not fatal). My trees are small BTW, all 0-3 years in the ground. No protection.

No frost in PQ. I'll have to check on my worms though, they don't like it when it gets below 40.

i have a worm bin
We just had a 100yr hard freeze in New Orleans (20F) a few weeks ago...
with all the stuff i was worried about, i forgot the worms.
they were perfectly fine.
the bin is a bit protected, but, i still imagine it had to get 25F.
i have also found tons of compost worms that have made their way into the garden over the years
(my castings have eggs and small worms).
all the dead plant material; is making them go nuts now that its warmed up.

i am really surprised my Myers lemon made it. and the orange.
i lost a 25yr satsuma though, but it was looking bad this whoile year anyway.
i lost things like natal plum and guava, which i thought were hardy (some made it)
pretty sure i lost the Grumichamas, and maybe even the Jabo (2 jabos should be fine, but lost twigs and stems )
mangos are toast. but they were from seed, and i kinda figured one year this would happen.
i am hoping the White sapote comes back. its 6ft tall (was)... i know the top was burned to hell.
i hope it flushes from the bottom or the roots.

last year my black sapote and Baobob didnt come back to life until early June (from the roots)

i had made the mistake of throwing out a few plants to reuse the pots on April.
wont do that this year.
i have a dozen containers with various subtropical dead-looking plants
they will just be an eyesore until July...

behlgarden · « **Reply #40 on:** February 22, 2018, 04:33:27 PM »

hit 34 this am, still no frost where I live in Corona.

Watch your trees in So Cal, and highly recommend watering them heavy around 2 AM, that will bring soil temp up from near freezing to about water temp over 50. Mangoes dont take freeze well, I have lost several in the past, some died after about month, leaf drop is imminent and show up quicker

gozp · « **Reply #41 on:** February 23, 2018, 01:48:27 PM »

Hit 32 early this AM.

We have hit 30 for 3 straight days. So far no damage.

I hope everyone gets through this crazy late season cold snap with little damage/casualties. So far, (knock on wood) I haven't seen a wiff of frost and my trees are doing pretty well. My santol got beat up a bit last week but is putting out new growth, and my mangosteen is looking fairly healthy but the new growth is a bit lackluster. Hopefully all will be well in a week or two. All seedlings have been fine on my patio: soursop, taitung SA, soncoya, langsat, madrono, achacha, plinias, sweet G. dulcis from Joshua... etc. Good luck everyone. Chris

I got my first frost of the year this morning. It was all over my car and on the weeds in my front yard. My White Pineapple got frosted back as they do every year but they will survive. Mangos are ok but I expect minor damage on new blooms and shoots. Here’s some pictures for today.

Only 37F here last night, 13 Miles inland. All soursop seedlings are inside already; annona scions still under wraps; budding mango scion still looks good; stone fruit trees are liking this...yes, hope yours are ok too!

We are not too far apart but I'm in the shallow valley between 2 hills (Anaheim hills and north tustin). I too had a thicker layer of frost on my car than I am used to.

Will have to check on plants. Last year 1/3 of my mangoes croaked about 3 weeks after the February frost. Brad, you re lucky the warm air rises. I did about 45 avocado grafts within the past few weeks. I just can't believe my rotten luck with weather and avocado grafts. If it's not Santa Ana's then its heavy rain and now frost following my avocado grafts.
