Gardeners' World continues with more timely tasks to keep our gardens looking their best. Monty Don gives his pond a spring clean and adds some much needed colour to his Jewel Garden pots. He also fleeces his tender plants. Carol Klein meets a young couple, Dan and Dom in Gloucestershire who are just getting started with their first garden. Over the course of the year, Carol will be helping and advising them on how to transform their small space into a lovely multifunctional family garden. Joe Swift visits a gardener in Northumberland who copes with temperatures of 18°C in the winter and 30°C in the summer. Despite these extremes, she has succeeded in developing a wonderful garden she can enjoy all year round. And we meet a grower whose love of butterflies and bees has inspired his fabulous and extensive collection of buddleja.
