Many plants are winding down for winter, however December is still a busy time for gardeners. We speak to the team at RHS Garden Wisley to find out the seasonal jobs they are doing around the garden. Our RHS Advisors answer your questions on subjects including: starting in a new garden from scratch, planting apple trees and how to care for olive trees. We discover the berries, flowers, colourful stems and evergreen foliage on display in Wisley's Winter Walk. There is also an update of the latest events taking place at our four RHS Gardens.
