Grow lights: when and how to use them

Kathy Clugston and the GQT team are in Tyne Valley, Newcastle.

Kathy's joined by Dr Chris Thorogood, Bethan Collerton and Matthew Wilson, who tackle a variety of questions from troubled Aspidistra, yellowing Choisya and planting for winter colour. The team also discusses beech hedges, how to tackle the issue of invasive Japanese knotweed and unlikely exotics thriving in northern gardens.

Later in the show, Bunny Guinness enlightens us on the benefits and use cases of grow lights within greenhouses.
