As May gets under way at Longmeadow, Monty Don turns his attention to his 'dry garden', an area where the soil is particularly thin and baked by the sun. He recommends plants which thrive in these conditions. Meanwhile, Rachel de Thame visits the gorgeous gardens of Coton Manor in Northamptonshire, where the owner has planted inspirational combinations in unpromising areas. Carol Klein meets a woman who loves gardening, not for plants, but for the creatures they attract to her South Devon garden. And back at Longmeadow, Monty introduces an area of his garden which regularly floods and demonstrates, through planting, how he has used this situation to enhance what he calls his 'damp garden'.
