Tring
The GQT team are in Tring for this week's horticultural programme.
How can I get rid of slugs without using pesticides? Will rhododendrons grow on chalky soil? Should we remove dead trees or leave them for wildlife?
Joining Peter Gibbs to answer these questions and more in front of a live audience in Tring are pest and disease expert Pippa Greenwood, plantsman Matt Biggs, and garden designer Juliet Sargeant.
Also on the programme, Pippa Greenwood visits her old lab at the RHS Wisley Plant Science Laboratory which will shortly open its doors to the public to showcase past and present research.

Q 鈥� I recently added rose beds to my son鈥檚 sterile AstroTurfed garden.听 We discovered a good eight inches of hardcore under the AstroTurf听which is still there albeit disturbed.听听 I used a mixture of topsoil and green manure, but this also seemed very sterile.听 I didn鈥檛 notice any worms.听 Will these arrive naturally, or should I be doing something else to encourage them?
