Tips from Center for Agriculture, Food and the Environment

Be prepared for winter storms

Winter storms and cold temperatures have been a challenge for greenhouse businesses in recent years. Storm damage to greenhouses have included racking of the frame, bending of the hoops, broken glass or torn plastic and uplifted foundation posts.

Snow that accumulates on a greenhouse can put significant weight on the structural members. Snow can be light and fluffy with a water equivalent of 12 inches of snow equal to 1 inch of rain. It can also be wet and heavy with 3 inches of snow equal to 1 inch of rain. Snow having a 1 inch of rain water equivalent will load a greenhouse with 5.2 psf. This amounts to 6.5 tons on a 25' X 96' greenhouse.

While we do not know what is in store for this winter, a little preparation before a storm can minimize damage from severe weather events.

Here are a few resources to help prepare for winter storms this season.

Also, in recent winters, frigid temperatures and frequent snow storms caused delays of shipments of plugs and cuttings for spring production which arrived chilled or frozen. The damage often showed within a few hours after exposure to warmer temperatures.

Learn to recognize the damage. See this article with photos: ďChilling Injury on Cuttings: What to look forĒ by Tom Dudek, Michigan State University Extension.
