Horticultural programme featuring a group of gardening experts, chaired by Kathy Clugston.
Horticultural programme featuring a group of gardening experts, chaired by Kathy Clugston. Fielding questions from across the country, this week, are Juliet Sargeant, James Wong, and Pippa Greenwood.
As the snowdrops begin to emerge from the soil, our panellists sit down to share their advice on using grow lights, nurturing bonsai trees, and battling an infestation of gnats.
Away from the questions, Matt Biggs sets sail to meet one gardener who has chosen to create a garden on top of her canal boat and Bob Flowerdew shares his advice on growing the yellowhorn, xanthoceras sorbifolium.

Q – I’d like to grow a living willow screen with an archway to divide my small garden. I’d like to plant a clematis or another climber, at least over the arch, to give it colour – is this realistic? And would I have to put the plants in a container or in the soil with the willow.
