Arkansas fruit growers assess damage from freeze, brace for second round of cold

Arkansas fruit growers are enduring a nervous week, sandwiched between two periods of freezing weather at a critical time for their crops.

A week ago, Arkansas’ fruit growers were assessing damage from a weekend freeze, while bracing for another round of cold.

Early spring is a critical time for Arkansas’ peach, apple and berry growers as their crops put out fruit-making blooms. Damage to the flowers can translate into no fruit being produced. For grape growers, some are seeing the tender and freeze-vulnerable first leaves or shoots on their vines.

In Washington County, where snow and sleet fell very recently, “some of our growers are seeing some major losses,” said Berni Kurz, county extension staff chair for the Division of Agriculture. “Blueberry losses are cultivar dependent so not a total loss with later blooming varieties not showing any signs of damage.

There were “some reports of heavy losses on strawberries under floating row covers—frost protection cloth,” he said. “Market gardeners have reported some losses on early season vegetables including broccoli, cauliflower and cabbage.

“What’s concerning is the low temperatures coming up,” Kurz said.

The National Weather Service at Tulsa said that “additional freezes look likely in the next several days. On a couple of mornings, it look like parts of far northwest Arkansas could see temps (of) 30 to 32 degrees.”

To cope, growers resort to floating row covers, burning hay in orchards to keep air temperatures above freezing for the trees surrounding the smoke and fire, and one grower has a helicopter to use its blades to fan warm air down into the orchard.

Fighting cold with ice

Ryan Neal, Benton County extension agent for the Division of Agriculture, has about four acres of blueberries. He uses an overhead watering system to protect the fruit from cold damage. While it sounds counterintuitive, keeping a wet icy layer on the fruit will maintain the temperature at 32 degrees, preventing damage. The technique does not work if the wind is blowing or it’s so dry the spray in effect becomes evaporative cooling. Neal has been using the system for two years and it covers about three-quarters of an acre.

“I’ll look to use it again,” he said. Neal said he didn’t turn it on last weekend because he was expecting a stiff wind. “When I awoke, there was a zero mile-an-hour wind and it was 24 degrees. I did get some damage” to early-season blueberries.

“The rest of the 3.5 acres look fine,” he said. “They’re still asleep.”

Still assessing

“We had some damage, but it’s still too early to tell fully what that will mean,” said Dan Chapman, director of the Fruit Research Station for the University of Arkansas System Division of Agriculture, said. “We’ve had damage to our grapes, but it’s hard to tell since the leaves aren’t uncurled yet. We’ve got some damage to our blueberries. The peaches are still looking good.

“There are a lot of factors when it comes to freeze damage such as elevation. Humidity can matter, whether there’s moisture on the ground or the ground is dry,” he said. “A lot has to do with the wind too and if there is home heat above, when you have a temperature inversion.”

Had the cold come later in the season, after fruit formation, damage might be less.

“The fruit can take more than the blooms because they have some sugar in them to keep them from freezing when it’s 32 degrees,” Chapman said, adding he hoped that the temperatures this weekend would stay in the mid-30s.

Amanda McWhirt, extension horticulture crop specialist for the Division of Agriculture, said she’s heard of fairly “extensive losses to blueberries in several parts of the state particularly on northern and southern highbush, but some of the later rabbiteyes still look OK further south,” she said. “Peaches have damage from the Missouri border down past Little Rock. Some damage is very extensive and others is spotty based on the farm location and varieties planted.

Matthew Davis, Jackson County extension agent, said his largest strawberry grower did see damage and there “will be minor crop loss, but fruit load on strawberries looks heavy.”

McWhirt said most strawberry growers put covers over their low-to-the-ground crop and protect the plants effectively.

“Overall, nothing is a total loss statewide, but several individual growers seem to have extensive losses for individual crops depending on the crop stage of development and how cold it got there,” McWhirt said.

Row crops

Jason Kelley, extension wheat and feed grains agronomist for the Division of Agriculture, posted photos of freeze-burned young corn plants on his Twitter feed.

“Impacts of freezing temps this weekend being seen on corn,” he said recently. “Looks rough now, will look worse over the next few days, but so far lots of healthy tissue below soil surface for recovery.”

Shortly after, he posted a photo of a damaged corn plant where green was reappearing. The forecast calls for storms and high winds and hail are likely to be the most worrisome for row crop producers.
