Plants are protected even if air temperatures dip down to 25 degrees provided it doesn’t stay that cold for too long. This spring, com and tomatoes even survived an early April sleet storm. On a sunny, breezy spring day, the temperature under the plastic is as much as 30 degrees warmer than the open air. On a cloudy, still day, the difference may only be four to six degrees.

They run east to west so the plastic catches more sunlight. When the continuous strip of plastic is laid down, water will drain off the slope, Stevens explains. Once the plants grow up to the plastic, it is rolled back. He used a special plow to make the unevenly ridged trenches; only two of these plows have ever been manufactured. However, homeowners could easily dig the trenches by hand and other plows could be adapted by growers working on a small scale. The sloped plastic covering didn’t work perfectly, Stevens admits. Some water collected. It may be necessary to poke a few holes in the plastic or sweep the water off by hand.
