The North West Enquirer (Manchester, U.K.) reports that Hayes Garden World in Ambleside, Holland, a leading garden center in the North West of the country, expects to sell 1.5 million tulips this year. The emerging trend in the bulb business in Holland is old-fashioned varieties of bulbs and prairie-style plantings.

The secret in planting bulbs, according to landscape architect Henk Koster, is to plant bulbs close together to get stands of color and to plant in layers. He pioneered the system of planting bulbs in layers at Keukenhof. Late flowering tulips are planted lower than normal, followed by a layer of soil or compost.
