Overview
Give your plants a helping hand through winter by adding a layer of bubble wrap to insulate your greenhouse. You'll have fewer draughts and will also benefit from lower bills if you use a heater during the very cold months.

late-autumn/winter
Takes just:
30 minutes
How to do it
-
Before buying any bubble wrap, measure the sides, roof and ends of the greenhouse. -
Starting with the sides, fix the bubble wrap to the frame using nails, drawing pins or wire, keeping it tight for extra insulation. -
When insulating the roof, fix the bubble wrap to the ridge and spread it down the glazing bars. -
Cut and fasten the bubble wrap around windows, vents and louvres so they can be opened.
"Choose polythene with large bubbles as this has better insulating properties and lets in more light."
"Buy bubble wrap by the metre from garden centres. Choose polythene that is specifically designed for greenhouses, as it is UV-stabilised and should last for at least three years."
