Easy to grow peonies, the right way to dig and herb of the month

This week David finds out more about the ultimate easy to grow plant – the peony. Grower Alec White explains why he gave up a career in law when he fell in love with their brilliant blooms and why they are a worthwhile investment, lasting over 50 years in the garden. Also on the programme, James Shippen on the biomechanics of digging and Jekka McVicar reveals the first of her herbs of the month. In studio Cherry Townsend will join David to answer questions and provide some winter gardening inspiration. Contact the programme on gardenerscorner@bbc.co.uk
