Cut-price perennials, tree of the month and RHS community gardens

This week David gets around the problem of pricey perennials by finding out just how easy many are to grow from seed. Ann Fitzsimmons recommends ‘first year flowering’ varieties and shows how sowing some seed now can save gardeners a small fortune. It’s the weekend of the RSPB’s big garden birdwatch. Listeners are invited to text in what they are seeing and Claire Barnett from the charity has all the information on how to take part. Also on the programme, the RHS is gifting 4 community or school gardens this year. David has been chatting to chief horticulturalist, Guy Barter, on what they are looking for. And in the first of a new series, Tony Kirkham, aka ‘the king of trees’ from the Royal Botanic Gardens, Kew on his favourite tree for January.
