Winter's a great time to clean your greenhouse to get rid of any lurking pests and diseases before the growing season begins.
It's likely to contain fewer plants now than at any other time of year, so clearing out will be easier, plus there aren't as many other jobs in the garden demanding your time.
Choose a day that is dry, sunny and calm and remove all your plants, tools and other items. Cover tender plants with fleece so they don't suffer in the cold outdoors.
Open the door and use maximum ventilation to let water evaporate as quickly as possible.
