Summer Garden Party RHS Wisley: Show 2
Kathy Clugston and the panel answer questions at the GQT Summer Garden Party on growing a clementine from pips, unusually shaped cacti, and using an unheated greenhouse in winter.
Kathy Clugston hosts the second of the Gardeners鈥� Question Time Summer Garden Party specials from RHS Garden Wisley in Surrey.
Joining Kathy are Pippa Greenwood, Matthew Wilson, Marcus Chilton-Jones and Dr Chris Thorogood, taking questions from an audience of keen gardeners gathered beneath the marquee at the Wisley Flower Show.
The panel share the gardening lessons they wish they鈥檇 learned sooner, help a young gardener who has successfully grown a clementine from pips and work on solving the mystery of some unusually shaped cacti.
There are also recommendations for planting up a sunny pergola, making the most of an unheated greenhouse through winter, and advice on how to treat against some unknown pests leaving marshmallow like residues on a well loved Hydrangea.
And to conclude, the panel almost break into song as they are asked if there is any music that inspires them to garden.
