Abstract
The purpose of this study was to determine the frost protection value of covering your plants in spring with polyethylene terephthalate (plastic) milk jugs or polyurethane rose cones. These coverings were placed in a field southeast of Kalamazoo, Michigan. Nocturnal temperatures were measured from May 7- 24, 1995 on clear and cloudy nights. Spring nocturnal temperatures inside one U.S. gallon milk jugs were slightly lower and those inside rose cones slightly higher than ambient air temperatures. Placing holes near the bases of these covers to provide additional circulation resulted in slightly lower nocturnal temperatures under the rose cones but no variation in temperatures within the milk jugs.
