Gardening Blog: re-skinning the polytunnel


Home » Gardening Blog: re-skinning the polytunnel

 

This week in the gardens, we put a new skin on the polytunnel. It’s necessary to put a new skin on every 3 or 4 years, or longer if possible. It was a team effort with staff from buildings and displays chipping it to help, while a warm brazier sat burning away to keep us warm. Roger’s polytunnel also has hot beds housing the first seedlings of the season. Hot beds are beds of food scraps mixed with compost. As they decompose, they warm up, providing good conditions to begin growing from seed.
