How can I control alexander plants? How can I encourage my gage trees to flower? What tips do the panellists have for increasing biodiversity? Kathy Clugston and her team of green-fingered experts are by the Suffolk Coast to share their advice with an audience of garden enthusiasts. On the panel are head gardeners Ashley Edwards and Matthew Pottage, and pest and disease expert Pippa Greenwood. Meanwhile, Matthew Pottage explores the Royal Botanic Garden, Sydney. He dons his hard hat to get up close with a particularly dangerous local pine and admires the wollemi pine, a living fossil thought to be extinct for two million years until a small population was discovered in the Blue Mountains of Australia in 1994.
