Bolton
Kathy Clugston and the GQT panel of experts visit Bolton to answer listener questions on sweet pea pruning, shady clay planting and compost bin conundrums.
Kathy Clugston and the Gardeners' Question Time panel visit the outskirts of Bolton in Lancashire. Kathy is joined by RHS Bridgewater Curator Marcus Chilton-Jones, Garden Designer Matthew Wilson and Plantswoman Christine Walkden.
The panellists tackle what to do about an overwhelming stash of black plastic pots, advise on why a listener's new compost bin is lacking in worms, and suggest plants for shady clay areas beneath mature beech trees.
Other questions cover planting for waterlogged borders, homemade foliar feeds for seedlings, and opening a wildlife-focused garden for the National Garden Scheme.
Later in the programme, Bunny Guinness shares spring propagation tips, including softwood and basal cuttings and using an aeroponic propagator.
