Kathy Clugston hosts this week's gardening Q&A with her panel of experts - Pippa Greenwood, Matthew Wilson and Matt Biggs. Together they answer questions emailed by listeners. This week, the panellists discuss the importance of Latin names in horticulture, offer suggestions for office planting and advise on the best pea growing techniques.
