Tring
The GQT team returns to Tring for this week's horticultural programme.
How do I get my cypress tree to be pencil thin? I grow vegetables in pots – how can I stop cats ‘going’ in them? Have I killed my husband’s beloved banana trees? When should I cut back my salvias to get a good display in the spring and summer?
Returning to Tring to answer these questions and more in front of a live audience are Peter Gibbs and this week’s panel: Pippa Greenwood, expert in pests and diseases, plantsman Matt Biggs, and garden designer Juliet Sargeant.
And Dr Chris Thorogood, GQT’s intrepid plant-hunter, went to Sumatra to hunt down the Titan Arum – Amorphophallus titanum – in its natural habitat.

Q Email from Douglas O’Shea
For 30 years I’ve admired the plane trees that line Kennington Road in London.Ìý I’ve noticed little silver placques nailed to the trees on the west side, each bearing the name of astronauts who’ve walked on, or orbited, the moon.Ìý Well, having heard GQT’s recent feature about Moon Trees – plane, grown from seed that had orbited the moon – I wondered if these trees might have been related.Ìý I mentioned it to a neighbour who said they were planted by the British Interplanetary Society based in Vauxhall – but they are too tall – at least 80 feet – to be only fifty years old.

Q – I try to garden with consideration for the eco-system, so I don’t cut anything down over the winter but on the very odd day that it’s sunny I’m desperate to get out there and start chopping things down.Ìý So what does the panel do to scratch that itch?
(34 minutes 04 seconds)Ìý
Ìý
Q What can I put in flower pots to keep cats out?Ìý I have a small garden and grow vegetables in pots – I find it quite irritating when I find cat pooh in my pots – it puts me off eating my produce.
