Frost damage in day-neutral strawberries

The official air temperature at the West Central Research and Outreach Center on October 4, 2014 was 32 degrees.  Even with the air temperature at 32, the temperature recorded in the low tunnel system was 34 degrees, which prevented the day neutral strawberry flowers and fruit from frost damage.  By comparison, the non low tunnel […]

Spotted wing drosophila

With any fruit crop, it is important to monitor and routinely check for insects and disease.  Once such insect that can be especially devastating to a strawberry crop is the spotted wing drosophila (SWD). In 2014, we changed our trap cup design.  We used a clear plastic quart-size cup, with lid, as seen below.  We […]

Strawberry leaf spot disease

In September, we noticed strawberry leaf spot in the non-low tunnel treatment, but not in the low tunnel.  This occurred at both the St. Paul and Morris locations.  For reasons unknown to us, the leaf spot affected only the non-low tunnel but not the low tunnel treatments.    

Mid-September Harvest

Even though cooler night temperatures in mid-September caused a decrease in fruit yield, the quality, appearance, size and flavor of these day-neutral strawberries remains excellent, as documented in our September 18 harvest:   Harvest began in early August for day-neutral varieties in both the low-tunnel and non-low tunnel systems, with two pickings per week.  The […]

Western flower thrips causes damage to non-low tunnel fruit

During the August 2014 harvest period, we noticed fruit damage from western flower thrips.  Western flower thrips are slender, very small insects, about 0.03 inch long when mature.  Adults have feathery wings and vary in color from yellow to dark brown; nymphs are white or yellowish with small dark eyes. Thrips feed on strawberry blossoms, […]

Twospotted spider makes an appearance in low-tunnel system

Twospotted spider mite damage was detected on the leaves of day-neutral strawberry plants under the low-tunnel system in late July.  While the damage was slight, it certainly came as a surprise since we did not experience this type of insect problem in 2013 with our low-tunnel system.  Typically, the twospotted spider mite is found in […]

Removing flower blossoms from day-neutral strawberries

In 2013 and 2014, we removed flower blossoms from day-neutral cultivars in early, mid and late June for optimum production.  Recently, we came across an experiment that shares some new information on when and why you should remove day-neutral flowers. University of Maryland Professors and Extension Educators released a publication in September of 2009 suggesting […]

Low Tunnel Tour!

The University of Minnesota (U of MN) and the West Central Research and Outreach Center (WCROC), Morris, invite you to a tour of our day-neutral low tunnel strawberry plot.  Tours will be held on Thursday, July 24, 2014 beginning at 5:15 pm and again at 7:30 pm, running one hour in length each time. The […]

Low tunnel construction for use with day-neutral strawberries

As the weather permits, we are beginning construction of our low-tunnel system in preparation for another growing season of day-neutral strawberries.  For detailed instructions on how to construct a raised bed, low-tunnel system for strawberry use, please refer to our Construction video, or visit the Construction post from May 2013. 

Gearing up for another growing season

We are gearing up for another exciting year of day-neutral low tunnel strawberry farming.  The growing season of 2013 provided us with valuable opportunities to learn how this system can work for strawberry growers in the Upper Midwest.  Based on what we learned, we are heading into our second year with a few tweaks and […]
