Postbag Edition: Seaton Delaval Hall
Kathy Clugston and the panel choose roses for a shaded memorial bed, investigate the collapse of a wisteria and unpick the mystery of a white flag iris that changed colour.
Kathy Clugston and the GQT team visit the Seaton Delaval Hall in Newcastle, to answer questions from the GQT postbag.
Today, the panel helps choose roses for a shaded memorial bed, investigates the sudden collapse of a once鈥慻lorious wisteria, and unpicks the mystery of a white flag iris that decided to flower again in autumn, but this time in blue.
Kathy is joined by Matthew Wilson, Bethan Collerton and Dr Chris Thorogood.
Alongside these questions, Sarah Peilow, Head Gardener at Seaton Delaval Hall takes us on a tour of the Parterre and the South East Garden.
