St Austell: Kiwis, Proud Plants and Frozen Seeds

When do kiwis produce fruit? What plant cuttings are you proud of propagating? Should we freeze seeds in water before planting them? Kathy Clugston and the panel have the answers.

When do kiwis produce fruit in the UK? What plant cuttings are the panel most proud of propagating? Should we freeze our seeds in water before planting them in the ground?

Kathy Clugston and a powerhouse panel of gardening experts return to the iconic Eden Project outside St Austell in Cornwall where they field questions from a green fingered live audience. Tackling everything from persistent pests to planting dilemmas, the panel includes houseplant specialist Anne Swithinbank, award-winning garden designer Chris Beardshaw, and horticulturalist Frances Tophill.

Later in the programme, continuing our autumn feature series, Matthew Wilson provides an extensive guide to dividing your perennial plants.
