After a week of storms, David heads to the gardens at Hillsborough Castle where Claire Woods is surveying the trees for damage. Claire explains that their approach is to leave as much of the wood as possible in situ as it supports all kinds of life. In the first of a new series, Oliver Shurmann reveals his perennial of the month which is Hepatica nobilis – a flower he first encountered as a child in Germany. Grace Loughrey has a small yard garden at her house off Belfast’s Ormeau Road where she also grows many houseplants. She’s in studio with a guide on how to make them thrive. Also on the programme, David chats to Seamus O’Brien (Kilmacurragh) and Alex Slazenger (Powerscourt) from the cloud forest near the Uganda/Congo border where they are part of an expedition searching for giant Lobelia and David is joined in studio by Mary Doris who will answer questions live.
