Ilvy Njiokiktjien for The New York Times AMSTERDAM — For tulip growers in the Netherlands, Friday the 13th of March this year was a true horror show. When tulip stems came up at the country’s largest flower market in Aalsmeer, the prices stalled over and over again at zero.

It pulls in 7 billion euros ($7.6 billion), with an average of $30 million in flowers sold daily. Tulip growers put their wares up for sale starting in March, when the flowers begin to bloom. Tulip season usually lasts about eight weeks. Some parts of the industry have been hit harder than others because of the coronavirus outbreak, said Mr. van Tol, depending on the market that producers or distributors […]
