It's a place where spring is king.

News 12’s Doug Geed takes us to an East End greenhouse operation where right now is their busiest time of year.

Between the arrival of spring, Easter and with Mother’s Day not far off, the demand for flowers is huge.

Kurt Weiss Greenhouses has been meeting the demand for decades.

“Overall we have between 9 and 10 million square feet. That makes us one of the largest greenhouse producers in the United States,” says Wayne Weiss.

The operation has 60 acres of greenhouses at their Center Moriches headquarters alone -- churning out traditional spring favorites including tulips and hydrangeas.

What they grow in Center Moriches is packed up and shipped out and trucked to box stores, supermarkets, garden centers and florists.

The fifth generation of the Weiss family is now involved in the business and it's certainly come a long way from when they were delivering flowers by horse-drawn carriage.

An automated planter is among the newest additions.

“It can plant three different species into one particular cell and make a combination liner,” says Weiss.
