Start preparations for its many cold-weather uses, says Ruth

TopTip

Invest in lots of horticultural fleece and a greenhouse heater, if possible, to help keep your most tender plants safe through the coldest nights.

1 A plant-packed summer greenhouse is a buffet for pests, so make sure you get rid of any lurkers. A fumigating candle is a good idea, but make sure you follow the instructions closely.

2 Remove stuck plant matter and mould from between the glass and frame using a thin piece of plastic. Make sure the panes are secured against winter storms.

3 Poor ventilation creates a breeding ground for mould and rot, so open doors and vents on warm days, closing them when the temperature drops.
