What to do in the garden when the temperature drops, Adam Frost’s Shrub of the Month and dealing with invasive Bamboo

As temperatures drop, David Maxwell is joined in studio by Ann FitzSimons to consider how to deal with snow and ice in the garden. He also heads to the National Trust’s Mount Stewart where despite the freezing weather work is continuing to reclaim areas of the garden lost to invasive bamboo. At the Chelsea Physic Garden in London, Emily Hazell explains how they protect tender species which already benefit from the urban heat island effect. She also explains her very precise rules for what stays and what gets cut down in the borders so they are tidy through the winter months. Also on the programme, Gardeners’ World presenter Adam Frost begins his Shrub of the Month series with his must-have shrub for January. Email the programme at gardenerscorner@bbc.co.uk
