Growing new plants and new gardeners, gardens to visit for free, solving courgette queries and replacing overgrown shrubs (Ep 148)

We visit RHS Garden Wisley to discover the new plant propagation facilities and what they mean for the gardeners there. And it's not just plants that the RHS is cultivating: as we look to the next generation of horticulturists there's still time to enter the Young School Gardener of the Year competition. Plus an exploration of our Partner Gardens, more than 200 glorious gardens nationwide (and overseas) that open their gates for free to RHS members at selected times throughout the year; and our advice team troubleshoots a poor courgette harvest and offers suggestions on replacing an overgrown shrub border.
