Scientist seeks no-shed Christmas trees

PUYALLUP, Wash., Dec. 14 (UPI) -- A Washington State University scientist and Christmas tree expert says he is close to genetically creating a breed of tree that doesn't shed its needles.

Gary Chastagner, who was dubbed "Mr. Christmas Tree" for his work in creating new species of Christmas trees, combating diseases in conifers and releasing guidelines for keeping trees fresh after cutting, said he hopes the needle-retaining fir trees will be available for holiday purchase within the next few years, The Seattle Times reported Monday.

Chastagner's research involved observing test trees and removing those that lost their needles too easily, while encouraging those that retained their needles to carry on their lineages at the university's Puyallup Research and Extension Center. He said 15 acres of conifers from all around the world grow at the center.

The scientist said the toughest test is finding trees that retain their needles after drying out.

"It's one thing if the tree goes dry," Chastagner said. "It's another if the tree goes dry and all the needles fall off."
