Sidmouth

Is there a place for sawdust in the veg patch? How best should I trim a mimosa? Can you share a remedy for my husband’s plant obsession?

Peter Gibbs and the GQT team are in Sidmouth answering questions from an audience of keen gardeners.

Joining Peter to share their tips, tricks and tales are plantswoman Anne Swithinbank, pest and disease expert, Pippa Greenwood, and Head of Horticulture at the Royal Parks, Matthew Pottage. The experts discuss wedding cake trees, whether to keep or cull a rhododendron, and the reasons why houseplants may struggle to flower.
