Banstead Downs

Peter Gibbs and the GQT team answer your questions from Banstead Downs.

What surprises might sprout from newly laid turf? What is the best compost? And what is 'companion planting'?

Joining Peter Gibbs this week are grow-your-own expert Bob Flowerdew, garden designer Bunny Guinness and Pippa Greenwood, our expert in pests and diseases.

In 2008, a special tree was planted in Flamstead, Bedfordshire. On the surface the plane tree seems normal, but it has an inter-galactic pedigree that is far from down-to-earth. Matt Biggs takes Dr Robert Massey from the Royal Astronomical Society and Professor Steve Miller from University College London to visit the tree and its owner.
