“Christmas strawberries?” requested Matthew Davis, Jackson County Extension staff chief for the College of Arkansas Division of Agriculture, in a Dec. 21 Fb put up. “The nice and cozy climate has prompted a number of strawberries to kind below the row covers.”

The early berries are a part of the analysis Davis is conducting on new strawberry varieties and measuring how they react to winter climate.




As soon as acclimated to cooler temperatures, strawberry vegetation are hardy all the way down to 10 levels Fahrenheit and foliage hardy all the way down to about 22 levels. Shorter days and cooler temperatures point out the plant is making ready for dormancy.

“It is inevitable. The row covers all the time come off,” Davis stated. “We usually use row covers to assist with fall progress due to the late planting. Attributable to enterprise restrictions, row covers are sometimes utilized and might not be eliminated till early March. The issue is that row covers forestall vegetation from reaching dormancy.

In his trial, Davis leaves half the vegetation in his strawberry rows uncovered. He’ll make weekly visits, observing injury and progress within the “crown or crowns,” the elements rising above the soil line within the middle of the plant.

“We actually wish to know if utilizing row covers may delay plant dormancy,” he stated. “Strawberries want a transition time that permits the plant to go dormant. Throughout that dormant interval, we turn out to be involved after we see temperatures reaching 15 levels Fahrenheit or beneath. When temperatures attain that low throughout dormancy, we glance to cowl or restore Any vegetation could also be in danger.

“The chilly might have an effect on every selection in another way,” Davis stated. “Crops will kind two to 5 sub-crowns main into spring. We wish to see one or two sub-crowns forming within the fall together with the primary crown. Chilly climate can injury the crowns and trigger delayed maturity or demise of the plant. These schemes will give us the chance To see any variegated variations in crown formation, injury and dormancy.

Among the many varieties included in Davis’ trials have been Camino Actual, Fronteras, Ruby John, Chandler, and some numbered varieties.

In northeast Arkansas, strawberries are typically stripped of their covers at totally different instances and when labor is offered, Davis stated, including that he hopes to be taught whether or not the covers have a optimistic or damaging impact on his growers’ productiveness.

For areas that aren’t carefully monitored, it’s tough to know in March whether or not injury to strawberries is brought on by chilly or different elements, such because the plant not being rooted correctly.
