Fig. 1. I suppose if I were a nature photographer, I would think this is a beautiful sight – it has that winter wonderland look! But, the thickness and whiteness of that ice tells me just how brutal last night was for this orchard and orchard grower. Having been a tree fruit grower in the early 80s, this photo brought back some not so great memories of the extreme damage and crop loss that a windborne freeze can cause. What all fruit growers (tree fruit and small fruit) have just experienced in the last 24 hours was actually WORSE than the Easter Freeze of 2007 (4/7-4/8/07). And, that is my view, and the view of Curtis Smith (Seven Springs, NC), and several veteran growers who I spoke with early this morning who have been around the industry for more than 30 years. This was THE BIG DADDY of ’em all! (Photo credit: Daniel Overcash, Regional Agronomist for Region 11: Cabarrus, Davidson, Davie, Forsyth, Iredell, Mecklenburg, Rowan, Stanly, Surry, Union, Yadkin).
Good late afternoon,
I think everyone is feeling pretty dazed at this moment from what we’ve just been hit by. And, in just a few hours, ROUND THREE begins! All I can say is, “the price of berries better go up this year!” We don’t have much time to regroup – the halftime buzzer is about to go off for what is shaping up to be challenging night of cold protection, but for many, if not most strawberry growers, I am happy to say that we’re still in the game! For sure, strawberry plants that might have had as many as a total of 20-25 excellent green fruits, blossoms, and popcorns going into last night may be down to 1/2 that number this afternoon, but the ones that are living are absolutely worth saving! But, as soon as we are through all this mess, you will need to get to work pretty quickly on some clean-up operations and spraying with captan.
1. What is different about tonight from last night?
- Temperatures tonight will potentially be colder than last night! This does not bode well for growers who are 100% reliant on row covers in areas going into low 20s and teens! Eric Hunter got to 18 F last night in Easley, SC, and he reported late this afternoon that, ” Just finished a round of inspecting under (double) covers. It appears the only real damage we have is where blooms touched the fabric. Other than that, all appears good. He also did single covers in some test locations. Basically, the crop got SMOKED with just single covers!!! Here is his very interesting report:
- “I left a few hundred plants covered only with 1.25oz covers – over 90% of those blooms were killed. I haven’t checked the popcorn stage blooms there yet. Also, he wrote: “Just found a row end where about 10 feet of 6 rows were covered with only a 1.5 oz. cover. 90% loss there as well.
- We have decided to put three covers on for tonight. We got through last night so we’re not gonna take a chance with missing by a few degrees tonight. I will do so tonight to see what happens.
Another grower in Greensboro, NC (Rudd Farm) did very well with a single cover by itself, and gave this report by phone to me early today:
- Greensboro, NC (9:30 a.m.) – it got to 21 F this morning, and a single one ounce cover provided nearly 10 F protection. The blossom reading was 30.7 F when the outside air was 21 F (source – Kenneth Rudd). They also ran water on top of covers but had an unbelievable night of trying to keep ice off the sprinklers. Even with sprinklers designed for this (frost proof), they had freezing up of these sprinklers within one hour of cutting on. In hindsight, they would have been better off not running! A blossom min of 30.7 is well above critical min of 28 for open bloom. The grower reported a bloom temp this morning (at same time under cover) with sprinkling of 32 F…well above the critical, but what work!
- Overall, I would say that if your location is going to drop down to 20, or maybe reach the upper teens tonight, a double cover is definitely recommended. But, that may not be an option at this late hour! So, you may be interested in this idea of adding some heat with drip…
- Something that is of great interest to a lot of growers is this idea of using drip beneath the row cover. It was used last night by a grower in VA Beach area who had a minimum of about 24 F this morning, and his crop came through with no issues today. He even mentioned that some rows with no covers, or anything for that matter, actually seemed to do pretty well and were putting out some new blooms today, and he and I were wondering if the drip might have made a difference there as well? No matter, a major concern with dripping is with potential of components of the drip system freezing up, and so this grower has decided to be more proactive in starting the drip up when blossom temps are around 33 F (using digital therm and thermocouple) – you could wait another few degrees and not start up until maybe 30-31 blossom temp, but he wishes to sidestep any problem with the system freezing, so he is starting sooner. There can be no doubt that adding a few degrees of heat under a row cover tonight (with colder temperatures than last night in many areas), is definitely desirable, and with these much lower wind speeds tonight compared to last evening, I think this approach can really work well.
- Sprinkling on top of row cover will be a favorite approach for many growers tonight. It can work very well in a situation where we have the potential for very cold temperatures, winds (see next section) and very low dew points. Here is a recap of how this procedure works:
- Sprinkling on top of row cover
- You can sprinkle on top of the cover to add heat back into the ice blanket system, as we did for the Easter freeze of 2007. This technique can be very successful in windborne freeze conditions, frost/freeze conditions (winds between 5-10 mph, and sub-freezing temps), or conditions where the row cover blanket is going to provide inadequate protection – LIKE TONIGHT in locations going into low 20s and teens
- For the ice blanket approach to work, you need a top notch sprinkling system, and you also need a digital thermometer to closely monitor bloom and bud temperatures all through the night. You really cannot tell if the sprinkling is helping or not without a digital thermometer and thermocouple wire that is inserted right into the blossom or bud.
- When the temperature of bloom under the cover reaches 32-33 F, start the irrigation on top of the row covers
- After you start sprinkling on top of the row covers, you will actually see from your digital thermometer that the bud and blossom temperatures immediately “pop up” (usually to about 38 F ). When water freezes there is a beneficial release of heat (called heat of fusion), and as long as you can keep sprinklers turning you will be able to maintain temperatures of the floral tissues above their critical temperature.
- In case of serious winds, you will definitely need extra labor to to knock ice off nozzles – in the early evening tonight with these high there is an excellent chance of nozzles freezing up.
- In case your pump fails, I have seen growers come through a situation like this as long as they could get their sprinklers “going again” – you may have up to 1 1/2 – 2 hours to get the irrigation running again — monitor bud and blossom temps with your digital thermometer to know how critical the patient may be?
- Keep running the water into Thursday morning after sunrise, and do not stop until the blossoms in coldest part of field are above 32 F. You should have at least 5 blossoms set up with thermocouple wires – Hopefully, you did remember to test your thermocouples (inserted in blossoms) before sunset tonight — make extra sure they are working! You may recall the afternoon advisory today where a grower in Sanford discovered that his blossom temps were reading 51 F at 11:30 a.m. (he had been sprinkling on covers all night), and I assured him it was ok to turn off. Basically, you don’t have to worry so much about wet bulb temps if you have a digital thermometer reading the true blossom temperature. As John Gross of Sanford said to me today, this takes all the guesswork out of it!
- Sprinkling on top of row cover
- Winds are still very much in the picture, but for the most part, we will be dealing with winds that are significantly lower than what we saw last night and today. Technically, many areas will be in what I refer to as a frost/freeze event tonight – this type of event has sub-freezing temperatures and winds in range of 5-10 mph. This type of event can be managed with sprinkling alone, but you really have to be on your game this late afternoon with the start up time for growers who will be sprinkling without the benefit of a row cover.
- Even now as we approach 5 p.m., winds are still howling out there! And, this makes things extremely difficult for start-up time. I just said we are going to be in a frost/freeze tonight, but we are still not there (winds are howling still). At the moment we are still experiencing windborne freeze type winds (10 mph and greater), but we fortunately don’t have sub-freezing temperatures yet. I have been in a lot of communication last night and again this morning with a grower over in Wilson area who managed to bring his blooms through last night with sprinkling (and, what an ordeal it has been), and now we are looking at starting up again as soon as air temperatures drop to around 39 F at 5 p.m.
- At 5 p.m. the wet bulb will be 29 F in Wilson-Rocky Mount area. Again, the air temp is still 39 F. Once you start irrigating in these high winds, you will see “evaporative cooling” reduce the effective temperature of the strawberry blossom to 29 F (that is what it will feel). Despite the ridiculous winds still at 5 p.m., we are going to get started now. If you start at 6 p.m. at this location, the wet bulb is only 27 F, and that can kill blooms right at start-up.
- By about 8 p.m. we will see winds drop to 8 p.m. (2000) – see the AWIS hourly: Rocky Mount Wilson And, from there (8 p.m.), it should be an OK evening for sprinkler irrigation by itself. Believe me, I don’t like this idea of starting in all this wind at 5 p.m.! How I wish this grower had had a little more row cover. But, he did not, and could not find any. The row cover would have let us delay start up until the blossoms get down to 30-31 on digital thermometer (this reminds me, if you have not checked the blossoms you are using for these readings, do so NOW). You may need to re-insert some of the thermocouple wires into blooms where they wiggled out!
- Let’s quickly examine Sanford, NC — please note that at this location we are not quite so rushed to get the watering going again – here we can wait until 1900 (7 p.m.) according to Sanford AWIS. At that time the air temp is forecast to be 39 F, and the wet bulb will be 30 F. I am waiting until 30 Wet Bulb (and not sooner) because of the high winds. Finally, at 7 p.m. winds will start to fall into the range of a frost/freeze, and not a windborne freeze windspeed of 10 mph+.SANFORD
- Because the buzzer for the next half just sounded, I am going to issue this advisory, as incomplete as it is, because growers in colder locations who are relying on sprinkling alone, need to be very very careful of their start up. Please note that when air temp gets to 39 in both Wilson and Sanford, that is when we need to be running water. That air temp of 39 relates to a wet bulb of about 30, and we don’t wish to play around with wet bulb start ups that would cause the blooms to feel a temperature of 28 or lower — that will cause what is referred to as “the cold jolt.”
For growers using irrigation alone tonight, please check when the wet bulb will be reaching 30 F in your location, using these AWIS hourly forecasts for the city/town closest to you, or the AWIS site that works best for your farm!
Remember, to make sure the ice you are making with your sprinkling is CLEAR and not MILKY.
This photo just was provided this afternoon by Daniel Overcash, Regional Agronomist for Region 11. Cloudy ice is an indication of problems with the sprinkling operation. I do see some possible issues with the appearance of the ice in this photo, but I will defer to Daniel on what the actual outcome might have been? The next photo shows perfect protection, but it was also a much easier night of cold protection some years ago.

SkyBit for a VA Grower near Richmond – it arrived in my email at 5:15 p.m. even though it says 8 p.m. It is indicating a very cold minimum of 21 F, and this will require use of sprinkling and row cover both. If you think you have problems tonight, I want you to open this pdf for Farmville, VA, and note that at 1800 (6 p.m.), the air temp will be 31 F, the dew point is -10 F, the wet bulb is 23 F, and winds are 13 mph. AWIS shows a low of 19 F tomorrow morning for Farmville (which is near the operation for this SkyBit, but runs a little colder). What is extraordinary is that at 1900 (7 p.m.) the dew point drops to – 32 F and wet bulb is 9 F. Farmville Hourly Detailed Weather Forecast
Good thing they have a row cover down, as well has have a top notch irrigation system. The grower wrote today: “We ran from 11:30 last night til 2:00 p.m. Min temp outside cover was 22. Temp under cover 41!!! We switched all sprinklers to Nelson rotators on 30×60 spacing. They don’t freeze up like impact sprinklers do. One more brutal night, then a 25 degree night piece of cake! Strawberries first week April here we come!”
They will start watering again his late afternoon or early evening when the blossom temps drop to 30-31 F. Of course, they could not manage this without having use of a digital thermometer with thermocouple assembly for monitoring bloom temps!
Not such a good row cover report for Sweet Charlies from Northern VA (5:30 p.m.)
Fig. __ This is Sweet Charlie with 1.25 Typar and two 0.9 s for a total of three covers. Not very good.
