Wading into wisteria, managing mildew and an existential conundrum

This week we’re exploring the lives of the pioneering women gardeners of the 20th century who paved the way for women in horticulture today… through music.

And finally we’re taking stock after a hot, dry summer. We visit Alex Paines at RHS Garden Rosemoor in Devon to explore how the gardeners there are adapting what, where, and how they plant.
