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‑glorious 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.
