Some Eastern NC Areas Will Likely See Frost Again Saturday Morning (5pm, Friday, March 9, 2018)

— Written By

Good afternoon,

In a quick review of AWIS Hourly Forecasts for locations across North Carolina, I did note that Fayetteville Fayetteville 3.10 and Elizabethtown Elizabethtown are potentially going to see frost Saturday morning. And, what is interesting to note is that the minimum air temp. for Elizabethtown will only be 36 F (at weather shelter height of 2 meters, or 6.56 ft).

Fig. 1. Minimum temperatures for North Carolina on Saturday morning

Recap of this last night and this morning:  In speaking to a grower in Kinston area I learned that there was a BIG FROST this Friday morning, and frost started as early as 2 a.m. Apparently, blossoms in direct contact with the cover were killed. Maybe the Louisiana “raised cover” system is starting to make a little more sense (Fig. 2)? It was also the case that running the drip under cover helped last night. In Kinston area it got down into the range of 26 F. Over in piedmont, I saw one grower location near  Greensboro that got down to 23 F this morning (yikes). Once you get to 24 F, you have pretty much run out of all safety margin with a 1 or 1.2 oz cover. That’s double-cover time, or possibly run the drip system to try to gain another a degree of protection. The best tool to tell you the true blossom temperature is a digital thermometer with thermocouple that is inserted in blossom (Fig. 3)/

Fig. 2. By providing a support structure to raise the cover, growers in LA can eliminate any frost losses due to blossoms coming in direct contact with the cover.

Fig. 3. Digital thermometer is a very useful tool for accurately determining blossom temperature. This unit cost about $232 before tax.

Photos from Chesnee, SC today at 2 p.m.

Fig. 4. Camarosa fresh dugs (from PEI) with about 15 blossoms/plant – covers just came off today. The entire acreage at this farm location in Chesnee, SC, had row cover protection – you can see covers off to the side.

Fig. 5. Close-up of Camarosa fresh dugs — obviously these blooms survived the recent frost events. By far, the fresh dugs are the most advanced in plant size and bloom.

Fig. 6. Cut-offs of Camarosa had about 3-5 blooms today -sorry about the cap Wolf Pack fans.
