This week why it’s good for you to eat as many different coloured fruit and veg as you can grow. A visit to Mount Venus nursery where Oliver Schurmann has a great collection on hellebores that are putting on an impressive show when little else does. In Glenarm, Neil Porteous is pruning grapes and Maurice Parkinson recommends Lonciera nitida as one of the best (and cheapest!) hedging plants available. Anna Hudson joins David in studio to take questions. Email the programme at [email protected]
