Is it better to propagate house plants in water or straight into soil? Is crop rotation necessary? What could I grow under my row of standard Bay Trees?

Kathy Clugston is in Chess Valley, Hertfordshire for this week's programme, along with her panel of horticultural experts = proud plantsman Matt Biggs, grow your own guru Bob Flowerdew, and pest and disease expert Pippa Greenwood.

Later, Juliet Sargeant transports us all the way to Zanzibar, East Africa, as she gives us a masterclass on the wide variety of spices the island has to offer and how you could potentially grow them in your own garden.
