Owners: Cathy and Joe Shipman Year established: 1987 Location: 20685 Main Road, Mattituck Phone: 631-298-4619 With 23 years in the Christmas tree business, Shamrock Christmas Tree Farm offers customers all the holiday trimmings they can imagine. Holiday products include field-grown Douglas fir trees, precut Fraser fir trees, fresh greens and balled trees. According to co-owner Joe Shipman, “We have a very large selection of field trees, and we take special care of all our precut trees, making sure they’re all kept in water until sold.” They also offer handmade wreaths, roping, grave blankets and kissing balls. Every Saturday and Sunday, Santa Claus comes to visit from noon to 5 p.m., and train rides around the farm are given Friday, Saturday and Sunday, weather permitting. Shoppers can enjoy complimentary hot chocolate and popcorn on the weekends, and this year Shamrock’s has added an outdoor fireplace to help keep off the chill. Shamrock Christmas Tree Farm is open daily from 9 a.m. to 5 p.m. through Dec. 24. You can visit online at shamrockchristmastrefarm.com.
