Testing the limits of cold tolerance
publication date: Feb 1, 2014
Weather extremes pose special challenges to farmers. They are responsible for painful crop losses and costly infrastructure damage, and let’s face it, it’s just no fun to work in 100 degree heat or -15 degree cold!
But weather extremes also provide valuable insight into the growth habits for our crops. This fall we planted kale, carrots, spinach, salad greens, and arugula in our greenhouses for winter harvest. Two of our greenhouses are heated to 30°F, two are unheated. Below is a summary of what survived the “polar vortex,” as meteorologists called the arctic cold wave that swept over the U.S. and Canada in January.
