Salvaging Your Greenhouse After a Heavy Snow Storm

A quick checklist covering potential hazards and steps to take to salvage your greenhouse after a heavy snow storm.
Be aware of potential hazards:
• Sliding snow or ice
• Falling glassAgri:
• Broken frame members
• Severed electrical wires
• Leaking fuel oil or gas
Shut off utilities:
• Disconnect power supply
• Shut of gas supply
• Turn of main water supply
Minimum structural damage:
• Take photos
• Prop up greenhouse frame to prevent further collapse
• Add additional bracing (diagonal at corners)
• Check and tighten frame connections
• Repair glazing
• Close doors and vents
• Open drain pipes
• Provide temporary heat to keep plants from freezing
• Check and repair heating/electrical/water systems
Major structural damage:
• Take photos
• Support frame members for safe entry
• Cut poly if necessary to reduce load on structure
• Clear aisles
• Remove plants to temporary structures or alternate location
• Drain water system
• Cover heating/cooling and materials handling equipment with tarps
Snow removal:
It can be very expensive to remove the snow. You also have to have space for it. If the snow is light, there is not much danger of further collapse. If it is heavy, some growers found that as it settled, melted and refroze, it formed a cocoon next to the greenhouse and didn’t add a lot of pressure. Removing it may cause more damage. If you need the light for the plants, then the snow will have to be removed.
Contact the insurance company.
Rent equipment to remove snow if necessary. Also rent to replace damaged heating/cooling equipment.

Upcoming Events
Food Safety Lunch and Learn Webinar Series
February 11, 2025 : Part One: What's Going on with Food Safety?
NYS Department of Agriculture and Markets FSMA inspectors are expected to step up farm visits this season. Why are they showing up on the farm asking about FSMA? Aren't we exempt? This noontime hour we will discuss the purpose of the farm visits and what produce farmers need to know.
February 18, 2025 : Part Two: What Counts as Food Processing?
In this session, we will discuss what counts as processing and what doesn't. Stories of inspectors coming to farmers markets and auctions telling some growers certain products can't be sold usually without much explanation. We will try to make some sense of things and clear up some misunderstandings so hopefully the upcoming season goes smoothly.
February 25, 2025 : Part Three: Traceability - Benefits for Food Safety and Beyond
Can having a traceback process for your produce (and other farm products) make good business sense regardless of FSMA regulations? We will (try to) make the case for farms to have some sort of traceability mechanism in place.
