Winter hasn't been too cruel this year, but Carole is still hoping to find out how hardy the plants are that she deliberately left in the ground last year to test their resilience. Meanwhile, George takes a look at his winter stem border that's full of plants that have been shining out in the darker months. Undercover, the glasshouse is a hive of activity at this time and Jim is sowing for Scotland. Chris continues to work on the pond area of the garden, planting a range of grasses on the banking but it's perhaps a little too early for the waders. Carole visits retired doctor and artist David Hawson, who has created a fascinating topiary garden in Monymusk.
