Preparing Your Greenhouse for Winter

Fall is just around the corner and it will soon be time to start prepping your greenhouse for winter. It is important to conduct proper up-keep of a greenhouse to prevent disease and mould. Here are a few steps to consider.

Clean your greenhouse out by:

• Removing seasonal plants
• Sweeping it out
• Disinfecting surfaces and floors with soapy water
• Clean the roof cover with a mild detergent
• Wash the entire structure and all gardening tools and accessories in the greenhouse
• Take inventory of tools and possibly reorganise them
• Clean off any shading paint to allow more sun and heat to enter during winter
• Ensure that after the clean, the greenhouse is thoroughly ventilated and dries out

Inspect the greenhouse by:

• Ensure the roof cover is not cracked
• Examine the insulation
• Possibly add additional insulation on the north facing wall
• Inspect heating system (if present)
• Inspect the ventilation system
• Replace any cracked panes
