About this episode
The episode provides tips for caring for potted plants during heatwaves and discusses powdery mildew and its management.
In a summer of rolling heatwaves, we look at what we can do to help out one of the garden areas most vulnerable to parching - plants in pots. RHS Horticultural Advisor Nick Turrell explains what you can do to keep them alive and thriving as temperatures soar. The heat and high humidity this summer have provided the perfect conditions for fungal plant diseases to spread like wildfire. RHS Plant Pathologist Dr Jassy Drakulic tells us about powdery mildew, and shares what you can do if your plants have succumbed. And finally, our Chief Horticulturist Guy Barter sheds some light on how we can make the most of this summer's most precious resource, when rainfall finally arrives where you are. Plus some listener questions answered.
