Monty Don, Carol Klein, Joe Swift and Rachel de Thame kick off the flower show season at the Malvern Spring Gardening Show. They revel in the beautiful flowers, all at the peak of perfection, in the floral marquee. They hunt for planting inspiration in the 21 show gardens and each of them scour the showground to find which plant, garden, gadget or display to choose as their 'best in show'.
