Castlewellan's walled garden reborn, Spring wildlife watch and Adam Frost's bulb of the month

Available for 30 days

David Maxwell visits the historic Annesley Walled Garden in Castlewellan Forest Park as it reopens to the public. The garden, which dates back to the mid-18th century, has been closed for two years while £1.3 million of improvement works were carried out. Head gardener Alwyn Sinnamon shows David the work done to the long borders and the gleaming glasshouses, restored to their former glory. David also explores the rediscovered Bog Garden and Rhododendron Wood. Adam Frost reveals his bulb for March, and there’s a visit to the Alpine House in Kew Gardens, which is celebrating its 20th birthday. In the studio, gardening expert Claire McNally joins David to answer questions, while wildlife expert Katy Bell uncovers the secret world of dragonflies.
