Presenter Monty Don talked about the blooms in a recent edition that featured show growers spending hundreds of hours tending plants. But Cheshire-based nursery Chrysanthemums Direct pointed out that the plants can grow easily in the garden without protection.
Exhibition manager Martyn Flint said everything has worked out because sales have boomed since the programme. "We were just a bit disappointed they didn't point out how easy they are to grow in the garden. But the show did a lot of good in terms of business," he added.
"Sales were markedly up in the week after the show - about 75 per cent. It got people interested. Interest has carried on into RHS Flower Show Cardiff (15-17 April). It's certainly been busy."
