This week on Gardeners' World, Monty Don shows us how to prepare for spring and summer with timely tasks in his damp garden and soft fruit area. Joe Swift continues his series of master classes on planting design to help us achieve the garden of our dreams. This week he is sharing tips on how to create a tropical green oasis. Carol Klein is in her Devon garden planting a viburnum that will give spring colour and fill the garden with fragrance. By considering its natural, native habitat, Carol shows how to plant it in the perfect place. We visit a couple that moved to a cottage in Cornwall and used their mastery of flower and foliage colour to turn a thin stretch of land into a beautiful garden. Back at Longmeadow Monty has advice on the best type of mulch to use for different planting conditions and he gets to grips with pruning his gooseberry and currant bushes.
