As part of the BBC's Big British Asian Summer, the team celebrates South Asian influences on British gardens. Monty Don visits a Hindu temple in Neasden, to learn more about the melding of the traditional Hindu Mandir and north-west London suburbia. Frances Tophill and Nick Bailey pick up growing advice from allotmenteers in Bradford and Birmingham. Plus, Joe Swift visits gardeners in Middlesex who have created a garden celebrating their Indian roots and the programme meets botanical horticulturist Bala Kompalli, who runs the orchid unit at Kew Gardens.
